The main -idea to achieve this, is the following: - -.. code-block:: python - - element.signal_name.connect(slot_name) - -All the interface's elements could be connected through signals to certain slots, -in the case of a `QAction`, the signal `triggered` can be used: - -.. code-block:: python - - exit_action.triggered.connect(slot_name) - -.. note:: Now a *slot* needs to be defined to exit the application, which can be done using - `QApplication.quit()`.

To do so, you -will add this procedure to the `Widget` constructor. - -.. warning:: Only for the example purpose a QTableWidget will be used, - but for more performance-critical applications the combination - of a model and a QTableView is encouraged. - -.. literalinclude:: steps/05-expenses.py - :linenos: - :lines: 48-73 - -As you can see, the code also includes a `QHBoxLayout` that provides the container to place widgets -horizontally. - -Additionally, the `QTableWidget` allows for customizing it, like adding the labels for the two -columns that will be used, and to *stretch* the content to use the whole `Widget` space. - -The last line of code refers to *filling the table**, and the code to perform that task is -displayed below. - -.. literalinclude:: steps/05-expenses.py - :linenos: - :lines: 75-81 - -Having this process on a separate method is a good practice to leave the constructor more readable, -and to split the main functions of the class in independent processes. - - -Right side layout ------------------ - -Because the data that is being used is just an example, you are required to include a mechanism to -input items to the table, and extra buttons to clear the table's content, and also quit the -application. - -To distribute these input lines and buttons, you will use a `QVBoxLayout` that allows you to place -elements vertically inside a layout. - -.. literalinclude:: steps/06-expenses.py - :linenos: - :lines: 64-80 - -Leaving the table on the left side and these newly included widgets to the right side -will be just a matter to add a layout to our main `QHBoxLayout` as you saw in the previous -example: - -.. literalinclude:: steps/06-expenses.py - :linenos: - :lines: 42-47 - -The next step will be connecting those new buttons to slots. - - -Adding elements ---------------- - -Each `QPushButton` have a signal called *clicked*, that is emitted when you click on the button. -This will be more than enough for this example, but you can see other signals in the `official -documentation <https://doc.qt.io/qtforpython/PySide2/QtWidgets/QAbstractButton.html#signals>`_. - -.. literalinclude:: steps/07-expenses.py - :linenos: - :lines: 92-95 - -As you can see on the previous lines, we are connecting each *clicked* signal to different slots. -In this example slots are normal class methods in charge of perform a determined task associated -with our buttons.
