There are two ways of doing this; -using the old style or the new style, which is more pythonic. Let's -use the new style in this case. You can find more information about -both these styles in the -`Signals and Slots in PySide2 <https://wiki.qt.io/Qt_for_Python_Signals_and_Slots>`_ -wiki page. - -The `QPushButton` has a predefined signal called **clicked**, which -is triggered every time the button is clicked.

We have also implemented the -`init()` method that calls the `QDialog`'s init method with the -parent widget, if any. Also, the new `setWindowTitle()` method -just sets the title of the dialog window. In `main()`, you can see -that we are creating a *Form object* and showing it to the world. - -Create the Widgets -=================== - -We are going to create two widgets: a `QLineEdit` where users can -enter their name, and a `QPushButton` that prints the contents of -the `QLineEdit`. -So, let's add the following code to the `init()` method of our Form: -:: - - # Create widgets - self.edit = QLineEdit("Write my name here..") - self.button = QPushButton("Show Greetings") - -It's obvious from the code that both widgets will show the corresponding -texts. - -Create a layout to organize the Widgets -======================================== - -Qt comes with layout-support that helps you organize the widgets -in your application. In this case, let's use `QVBoxLayout` to lay out -the widgets vertically. Add the following code to the `init()` method, -after creating the widgets: -:: - - # Create layout and add widgets - layout = QVBoxLayout() - layout.addWidget(self.edit) - layout.addWidget(self.button) - # Set dialog layout - self.setLayout(layout) - -So, we create the layout, add the widgets with `addWidget()`, -and finally we say that our **Form** will have our `QVBoxLayout` -as its layout. - -Create the function to greet and connect the Button -==================================================== - -Finally, we just have to add a function to our custom **Form** -and *connect* our button to it. Our function will be a part of -the Form, so you have to add it after the `init()` function: -:: - - # Greets the user - def greetings(self): - print ("Hello {}".format(self.edit.text())) - -Our function just prints the contents of the `QLineEdit` to the -python console. We have access to the text by means of the -`QLineEdit.text()` method. - -Now that we have everything, we just need to *connect* the -`QPushButton` to the `Form.greetings()` method.

The second is preferred in this case, so you can verify -if the two inputs are not empty to enable the button *Add*. - -.. note:: Qt also provides a special class called - `QValidator <https://doc.qt.io/qtforpython/PySide2/QtGui/QValidator.html?highlight=qvalidator>`_ - that you can use to validate any input. - -Empty chart view ----------------- - -New items can be added to the table, and the visualization is so far -OK, but you can accomplish more by representing the data graphically. - -First you will include an empty `QChartView` placeholder into the right -side of your application. - -.. literalinclude:: steps/09-expenses.py - :linenos: - :lines: 66-68 - -Additionally the order of how you include widgets to the right -`QVBoxLayout` will also change. - -.. literalinclude:: steps/09-expenses.py - :linenos: - :lines: 81-91 - :emphasize-lines: 9 - -Notice that before we had a line with `self.right.addStretch()` -to fill up the vertical space between the *Add* and the *Clear* buttons, -but now, with the `QChartView` it will not be necessary. - -Also, you need include a *Plot* button if you want to do it on-demand. - -Full application ----------------- - -For the final step, you will need to connect the *Plot* button -to a slot that creates a chart and includes it into your `QChartView`. - -.. literalinclude:: steps/10-expenses.py - :linenos: - :lines: 103-109 - :emphasize-lines: 6 - -That is nothing new, since you already did it for the other buttons, -but now take a look at how to create a chart and include it into -your `QChartView`. - -.. literalinclude:: steps/10-expenses.py - :linenos: - :lines: 139-151 - -The following steps show how to fill a `QPieSeries`: - - * create a `QPieSeries`, - * iterate over the table row IDs, - * get the items at the *i* position, - * add those values to the *series*. - -Once the series has been populated with our data, you create a new `QChart`, -add the series on it, and optionally set an alignment for the legend. - -The final line `self.chart_view.setChart(chart)` is in charge of bringing -your newly created chart to the `QChartView`. - -The application will look like this: - -.. image:: expenses_tool.png - -And now you can see the whole code: - -.. literalinclude:: main.py - :linenos: diff --git a/sources/pyside2/doc/tutorials/expenses/expenses_tool.png b/sources/pyside2/doc/tutorials/expenses/expenses_tool.png Binary files differdeleted file mode 100644 index 7a6f6d1f0..000000000 --- a/sources/pyside2/doc/tutorials/expenses/expenses_tool.png +++ /dev/null diff --git a/sources/pyside2/doc/tutorials/expenses/main.py b/sources/pyside2/doc/tutorials/expenses/main.py deleted file mode 100644 index 5dd632301..000000000 --- a/sources/pyside2/doc/tutorials/expenses/main.py +++ /dev/null @@ -1,207 +0,0 @@ -############################################################################# -## -## Copyright (C) 2020 The Qt Company Ltd. -## Contact: http://www.qt.io/licensing/ -## -## This file is part of the Qt for Python examples of the Qt Toolkit. -## -## $QT_BEGIN_LICENSE:BSD$ -## You may use this file under the terms of the BSD license as follows: -## -## "Redistribution and use in source and binary forms, with or without -## modification, are permitted provided that the following conditions are -## met: -## * Redistributions of source code must retain the above copyright -## notice, this list of conditions and the following disclaimer. -## * Redistributions in binary form must reproduce the above copyright -## notice, this list of conditions and the following disclaimer in -## the documentation and/or other materials provided with the -## distribution. -## * Neither the name of The Qt Company Ltd nor the names of its -## contributors may be used to endorse or promote products derived -## from this software without specific prior written permission. -## -## -## THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS -## "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT -## LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR -## A PARTICULAR PURPOSE ARE DISCLAIMED.

Try porting a Qt C++ application -to Python to understand this. - -Before you start, ensure that all the prerequisites for -Qt for Python are met. See -:doc:`Getting Started <../../gettingstarted>` for more -information. In addition, familiarize yourself with the -basic differences between Qt in C++ and in Python. - -Basic differences -================== - -This section highlights some of the basic differences -between C++ and Python, and how Qt differs between these -two contexts. - -C++ vs Python --------------- - -* In the interest of code reuse, both C++ and Python - provide ways for one file of code to use facilities - provided by another. In C++, this is done using the - ``#include`` directive to access the API definition of - the reused code. The Python equivalent is an ``import`` - statement. -* The constructor of a C++ class shares the name of its - class and automatically calls the constructor of any - base-classes (in a predefined order) before it runs. - In Python, the ``__init__()`` method is the constructor - of the class, and it can explicitly call base-class - constructors in any order. -* C++ uses the keyword, ``this``, to implicitly refer to - the current object. In python, you need to explicitly - mention the current object as the first parameter - to each instance method of the class; it is conventionally - named ``self``. -* And more importantly, forget about curly braces, {}, and - semi-colon, ;. -* Precede variable definitions with the ``global`` keyword, - only if they need global scope. - -.. code:: python - - var = None - def func(key, value = None): - """Does stuff with a key and an optional value. - - If value is omitted or None, the value from func()'s - last call is reused. - """ - global var - if value is None: - if var is None: - raise ValueError("Must pass a value on first call", key, value) - value = var - else: - var = value - doStuff(key, value) - -In this example, ``func()`` would treat ``var`` as a local -name without the ``global`` statement. This would lead to -a ``NameError`` in the ``value is None`` handling, on -accessing ``var``. For more information about this, see -`Python refernce documentation <python refdoc>`_. - -.. _python refdoc: https://docs.python.org/3/reference/simple_stmts.html#the-global-statement - -.. tip:: Python being an interpreted language, most often - the easiest way is to try your idea in the interperter. - You could call the ``help()`` function in the - interpreter on any built-in function or keyword in - Python. For example, a call to ``help(import)`` should - provide documentation about the ``import`` statment - -Last but not the least, try out a few examples to -familiarize yourself with the Python coding style and -follow the guidelines outlined in the -`PEP8 - Style Guide <pep8>`_. - -.. _pep8: <https://www.python.org/dev/peps/pep-0008/#naming-conventions> - -.. code-block:: python - - import sys - - from PySide2.QtWidgets import QApplication, QLabel - - app = QApplication(sys.argv) - label = QLabel("Hello World") - label.show() - sys.exit(app.exec_()) - -.. note:: Qt provides classes that are meant to manage - the application-specific requirements depending on - whether the application is console-only - (QCoreApplication), GUI with QtWidgets (QApplication), - or GUI without QtWidgets (QGuiApplication). These - classes load necessary plugins, such as the GUI - libraries required by an application. In this case, it is - QApplication that is initialized first as the application - has a GUI with QtWidgets. - -Qt in the C++ and Python context ---------------------------------- - -Qt behaves the same irrespective of whether it is used -in a C++ or a Python application. Considering that C++ -and Python use different language semantics, some -differences between the two variants of Qt are inevitable. -Here are a few important ones that you must be aware of: - -* **Qt Properties**: ``Q_PROPERTY`` macros are used in C++ to add a - public member variable with getter and setter functions. Python's - alternative for this is the ``@property`` decorator before the - getter and setter function definitions. -* **Qt Signals and Slots**: Qt offers a unique callback mechanism, - where a signal is emitted to notify the occurrence of an event, so - that slots connected to this signal can react to it. In C++, - the class definition must define the slots under the - ``public Q_SLOTS:`` and signals under ``Q_SIGNALS:`` - access specifier. You connect these two using one of the - several variants of the QObject::connect() function. Python's - equivalent for this is the `@Slot`` decorator just before the - function definition. This is necessary to register the slots - with the QtMetaObject. -* **QString, QVariant, and other types** - - - Qt for Python does not provide access to QString and - QVariant. You must use Python's native types instead. - - QChar and QStringRef are represented as Python strings, - and QStringList is converted to a list of strings. - - QDate, QDateTime, QTime, and QUrl's __hash__() methods - return a string representation so that identical dates - (and identical date/times or times or URLs) have - identical hash values. - - QTextStream's bin(), hex(), and oct() functions are - renamed to bin_(), hex_(), and oct_() respectively. This - should avoid name conflicts with Python's built-in - functions. - -* **QByteArray**: A QByteArray is treated as a list of - bytes without encoding. Python 3 uses - "bytes". QString is represented as an encoded human readable string, - which means it is a "str". - -Here is the improved version of the Hello World example, -demonstrating some of these differences: - -.. literalinclude:: hello_world_ex.py - :linenos: - :lines: 40- - -.. note:: The ``if`` block is just a good practice when - developing a Python application. It lets the Python file - behave differently depending on whether it is imported - as a module in another file or run directly. The - ``__name__`` variable will have different values in - these two scenarios. It is ``__main__`` when the file is - run directly, and the module's file name - (``hello_world_ex`` in this case) when imported as a - module. In the later case, everything defined in the - module except the ``if`` block is available to the - importing file. - -Notice that the QPushButton's ``clicked`` signal is -connected to the ``magic`` function to randomly change the -QLabel's ``text`` property. The `@Slot`` decorator marks -the methods that are slots and informs the QtMetaObject about -them. - -Porting a Qt C++ example -========================= - -Qt offers several C++ examples to showcase its features and help -beginners learn. You can try porting one of these C++ examples to -Python. The -`books SQL example <https://code.qt.io/cgit/qt/qtbase.git/tree/examples/sql/books>`_ -is a good starting point as it does not require you to write UI-specific code in -Python, but can use its ``.ui`` file instead. - -The following chapters guides you through the porting process: - -.. toctree:: - :glob: - :titlesonly: - - chapter1/chapter1 - chapter2/chapter2 - chapter3/chapter3 diff --git a/sources/pyside2/doc/tutorials/qmlapp/logo.png b/sources/pyside2/doc/tutorials/qmlapp/logo.png Binary files differdeleted file mode 100644 index 30c621c9c..000000000 --- a/sources/pyside2/doc/tutorials/qmlapp/logo.png +++ /dev/null diff --git a/sources/pyside2/doc/tutorials/qmlapp/main.py b/sources/pyside2/doc/tutorials/qmlapp/main.py deleted file mode 100644 index 54edf0e37..000000000 --- a/sources/pyside2/doc/tutorials/qmlapp/main.py +++ /dev/null @@ -1,82 +0,0 @@ -############################################################################# -## -## Copyright (C) 2019 The Qt Company Ltd. -## Contact: http://www.qt.io/licensing/ -## -## This file is part of the Qt for Python examples of the Qt Toolkit. -## -## $QT_BEGIN_LICENSE:BSD$ -## You may use this file under the terms of the BSD license as follows: -## -## "Redistribution and use in source and binary forms, with or without -## modification, are permitted provided that the following conditions are -## met: -## * Redistributions of source code must retain the above copyright -## notice, this list of conditions and the following disclaimer. -## * Redistributions in binary form must reproduce the above copyright -## notice, this list of conditions and the following disclaimer in -## the documentation and/or other materials provided with the -## distribution. -## * Neither the name of The Qt Company Ltd nor the names of its -## contributors may be used to endorse or promote products derived -## from this software without specific prior written permission. -## -## -## THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS -## "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT -## LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR -## A PARTICULAR PURPOSE ARE DISCLAIMED.

QML is a declarative language that lets you design UIs faster than a traditional -language, such as C++. The QtQml and QtQuick modules provides the necessary infrastructure for -QML-based UIs. - -In this tutorial, you will learn how to integrate Python with a QML application through a context -property. This mechanism will help us to understand how to use Python as a backend for certain -signals from the UI elements in the QML interface. Additionally, you will learn how to provide -a modern look to your QML application using one of the features from Qt Quick Controls 2. - -The tutorial is based on an application that allow you to set many text properties, like increasing -the font size, changing the color, changing the style, and so on. Before you begin, install the -`PySide2 <https://pypi.org/project/PySide2/>`_ Python packages. - -The following step-by-step process will guide you through the key elements of the QML based -application and PySide2 integration: - -#. First, let's start with the following QML-based UI: - - .. image:: textproperties_default.png - - The design is based on a `GridLayout`, containing two `ColumnLayout`. - Inside the UI you will find many `RadioButton`, `Button`, and a `Slider`. - -#. With the QML file in place, you can load it from Python: - - .. literalinclude:: main.py - :linenos: - :lines: 98-108 - :emphasize-lines: 6,9 - - Notice that we specify the name of the context property, **con**, - and also we explicitly load our QML file. - -#. Define the `Bridge` class, containing all the logic for the context property: - - .. literalinclude:: main.py - :linenos: - :lines: 51-91 - -#. Now, go back to the QML file and connect the signals to the slots defined in the `Bridge` class: - - .. literalinclude:: view.qml - :linenos: - :lines: 85-93 - :emphasize-lines: 5-7 - - The properties *Italic*, *Bold*, and *Underline* are mutually - exclusive, this means only one can be active at any time. - To achieve this each time we select one of these options, we - check the three properties via the context property as you can - see in the above snippet. - Only one of the three will return *True*, while the other two - will return *False*, that is how we make sure only one is being - applied to the text. - -#. Each slot verifies if the selected option contains the text associated - to the property: - - .. literalinclude:: main.py - :linenos: - :lines: 79-84 - :emphasize-lines: 4,6 - - Returning *True* or *False* allows you to activate and deactivate - the properties of the QML UI elements. - - It is also possible to return other values that are not *Boolean*, - like the slot in charge of returning the font size: - - .. literalinclude:: main.py - :linenos: - :lines: 64-70 - -#. Now, for changing the look of our application, you have two options: - - 1. Use the command line: execute the python file adding the option, `--style`:: - - python main.py --style material - - 2. Use a `qtquickcontrols2.conf` file: - - .. literalinclude:: qtquickcontrols2.conf - :linenos: - - Then add it to your `.qrc` file: - - .. literalinclude:: style.qrc - :linenos: - - Generate the *rc* file running, `pyside2-rcc style.qrc > style_rc.py` - And finally import it from your `main.py` script. - - .. literalinclude:: main.py - :linenos: - :lines: 41-48 - :emphasize-lines: 8 - - You can read more about this configuration file - `here <https://doc.qt.io/qt-5/qtquickcontrols2-configuration.html>`_. - - The final look of your application will be: - - .. image:: textproperties_material.png - -You can :download:`view.qml <view.qml>` and -:download:`main.py <main.py>` to try this example. diff --git a/sources/pyside2/doc/tutorials/qmlintegration/qtquickcontrols2.conf b/sources/pyside2/doc/tutorials/qmlintegration/qtquickcontrols2.conf deleted file mode 100644 index 850646021..000000000 --- a/sources/pyside2/doc/tutorials/qmlintegration/qtquickcontrols2.conf +++ /dev/null @@ -1,10 +0,0 @@ -[Controls] -Style=Material - -[Universal] -Theme=System -Accent=Red - -[Material] -Theme=Dark -Accent=Red diff --git a/sources/pyside2/doc/tutorials/qmlintegration/style.qrc b/sources/pyside2/doc/tutorials/qmlintegration/style.qrc deleted file mode 100644 index e313f5ed6..000000000 --- a/sources/pyside2/doc/tutorials/qmlintegration/style.qrc +++ /dev/null @@ -1,5 +0,0 @@ -<!DOCTYPE RCC><RCC version="1.0"> -<qresource prefix="/"> - <file>qtquickcontrols2.conf</file> -</qresource> -</RCC> diff --git a/sources/pyside2/doc/tutorials/qmlintegration/textproperties_default.png b/sources/pyside2/doc/tutorials/qmlintegration/textproperties_default.png Binary files differdeleted file mode 100644 index cfeac9368..000000000 --- a/sources/pyside2/doc/tutorials/qmlintegration/textproperties_default.png +++ /dev/null diff --git a/sources/pyside2/doc/tutorials/qmlintegration/textproperties_material.png b/sources/pyside2/doc/tutorials/qmlintegration/textproperties_material.png Binary files differdeleted file mode 100644 index 47866c10e..000000000 --- a/sources/pyside2/doc/tutorials/qmlintegration/textproperties_material.png +++ /dev/null diff --git a/sources/pyside2/doc/tutorials/qmlintegration/view.qml b/sources/pyside2/doc/tutorials/qmlintegration/view.qml deleted file mode 100644 index 97968d691..000000000 --- a/sources/pyside2/doc/tutorials/qmlintegration/view.qml +++ /dev/null @@ -1,183 +0,0 @@ -/**************************************************************************** -** -** Copyright (C) 2019 The Qt Company Ltd. -** Contact: http://www.qt.io/licensing/ -** -** This file is part of the Qt for Python examples of the Qt Toolkit. -** -** $QT_BEGIN_LICENSE:BSD$ -** You may use this file under the terms of the BSD license as follows: -** -** "Redistribution and use in source and binary forms, with or without -** modification, are permitted provided that the following conditions are -** met: -** * Redistributions of source code must retain the above copyright -** notice, this list of conditions and the following disclaimer. -** * Redistributions in binary form must reproduce the above copyright -** notice, this list of conditions and the following disclaimer in -** the documentation and/or other materials provided with the -** distribution. -** * Neither the name of The Qt Company Ltd nor the names of its -** contributors may be used to endorse or promote products derived -** from this software without specific prior written permission. -** -** -** THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS -** "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT -** LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR -** A PARTICULAR PURPOSE ARE DISCLAIMED.

-There are two ways of laying out items in QML: `Item Positioners`_ and `Qt Quick Layouts`_. - -- Item positioners (`Row`_, `Column`_, and so on) are useful for situations where the size of items - is known or fixed, and all that is required is to neatly position them in a certain formation. -- The layouts in Qt Quick Layouts can both position and resize items, making them well suited for - resizable user interfaces. - Below, we use `ColumnLayout`_ to vertically lay out a `ListView`_ and a `Pane`_. - - .. literalinclude:: chat.qml - :linenos: - :lines: 50-53 - -Pane is basically a rectangle whose color comes from the application's style. -It's similar to `Frame`_, but it has no stroke around its border. - -Items that are direct children of a layout have various `attached properties`_ available to them. -We use `Layout.fillWidth`_ and `Layout.fillHeight`_ on the `ListView`_ to ensure that it takes as -much space within the `ColumnLayout`_ as it can, and the same is done for the Pane. -As `ColumnLayout`_ is a vertical layout, there aren't any items to the left or right of each child, -so this results in each item consuming the entire width of the layout. - -On the other hand, the `Layout.fillHeight`_ statement in the `ListView`_ enables it to occupy the -remaining space that is left after accommodating the Pane. - -.. _Item Positioners: https://doc.qt.io/qt-5/qtquick-positioning-layouts.html -.. _Qt Quick Layouts: https://doc.qt.io/qt-5/qtquicklayouts-index.html -.. _Row: https://doc.qt.io/qt-5/qml-qtquick-row.html -.. _Column: https://doc.qt.io/qt-5/qml-qtquick-column.html -.. _ColumnLayout: https://doc.qt.io/qt-5/qml-qtquick-layouts-columnlayout.html -.. _ListView: https://doc.qt.io/qt-5/qml-qtquick-listview.html -.. _Pane: https://doc.qt.io/qt-5/qml-qtquick-controls2-pane.html -.. _Frame: https://doc.qt.io/qt-5/qml-qtquick-controls2-frame.html -.. _attached properties: https://doc.qt.io/qt-5/qml-qtquick-layouts-layout.html -.. _Layout.fillWidth: https://doc.qt.io/qt-5/qml-qtquick-layouts-layout.html#fillWidth-attached-prop -.. _Layout.fillHeight: https://doc.qt.io/qt-5/qml-qtquick-layouts-layout.html#fillHeight-attached-prop -.. _ListView: https://doc.qt.io/qt-5/qml-qtquick-listview.html -.. _Qt Quick QML Types: https://doc.qt.io/qt-5/qtquick-qmlmodule.html - -Let's look at the ``Listview`` in detail: - - .. literalinclude:: chat.qml - :linenos: - :lines: 53-99 - -After filling the ``width`` and ``height`` of its parent, we also set some margins on the view. - - -Next, we set `displayMarginBeginning`_ and `displayMarginEnd`_. -These properties ensure that the delegates outside the view don't disappear when you -scroll at the edges of the view. -To get a better understanding, consider commenting out the properties and then rerun your code. -Now watch what happens when you scroll the view. - -We then flip the vertical direction of the view, so that first items are at the bottom. - -Additionally, messages sent by the contact should be distinguished from those sent by a contact. -For now, when a message is sent by you, we set a ``sentByMe`` property, to alternate between -different contacts. -Using this property, we distinguish between different contacts in two ways: - -* Messages sent by the contact are aligned to the right side of the screen by setting - ``anchors.right`` to ``parent.right``. -* We change the color of the rectangle depending on the contact. - Since we don't want to display dark text on a dark background, and vice versa, we also set the - text color depending on who the contact is. - -At the bottom of the screen, we place a `TextArea`_ item to allow multi-line text input, and a -button to send the message. -We use Pane to cover the area under these two items: - - .. literalinclude:: chat.qml - :linenos: - :lines: 101-125 - -The `TextArea`_ should fill the available width of the screen. -We assign some placeholder text to provide a visual cue to the contact as to where they should begin -typing. -The text within the input area is wrapped to ensure that it does not go outside of the screen. - -Lastly, we have a button that allows us to call the ``send_message`` method we defined on -``sqlDialog.py``, since we're just having a mock up example here and there is only one possible -recipient and one possible sender for this conversation we're just using strings here. -
