* Fix hellowindow exampleMichal Klocek2020-05-251-44/+21
| | | | | | | | | | | | | | | | | | | | It seems this example never worked as expected. It has a 'multiple' option which should show extra windows with rendering taking place in different thread, however although render is moved to other thread render() function was never called in that thread. Fix following things: * make rendering in other thread * stop requestUpdate if nothing is exposed * add timer so animation works at the same speed despite of number of windows (renderer B renders two windows) * wait for render to finish before triggering requestUdpate * remove mutex where not needed Pick-to: 5.15 Change-Id: I420436bd28d0357534332dd55b088d634d906c14 Reviewed-by: Laszlo Agocs <laszlo.agocs@qt.io>

* Change almost all other uses of qrand() to QRandomGeneratorThiago Macieira2017-11-081-3/+4
| | | | | | | | | | | | | | | | | | | The vast majority is actually switched to QRandomGenerator::bounded(), which gives a mostly uniform distribution over the [0, bound) range. There are very few floating point cases left, as many of those that did use floating point did not need to, after all. (I did leave some that were too ugly for me to understand) This commit also found a couple of calls to rand() instead of qrand(). This commit does not include changes to SSL code that continues to use qrand() (job for someone else): src/network/ssl/qsslkey_qt.cpp src/network/ssl/qsslsocket_mac.cpp tests/auto/network/ssl/qsslsocket/tst_qsslsocket.cpp Change-Id: Icd0e0d4b27cb4e5eb892fffd14b5285d43f4afbf Reviewed-by: Lars Knoll <lars.knoll@qt.io>

* Be (somewhat more) consistent about the value of piEdward Welbourne2017-06-201-13/+12
| | | | | | | | | | | | | | | | | | | | Use M_PI (and friends), where possible, in favor of hand-coded approximations of various (in)accuracies. Where that's not available (e.g. fragment shaders), use the same value that qmath.h uses for M_PI, for consistency. Replaced math.h with qmath.h in places that defined a fall-back in case math.h omits it (it's not in the C++ standard, although M_PI is in POSIX); or removed this entirely where it wasn't used. Reworked some code to reduce the amount of arithmetic needed, in the process; e.g. pulling common factors out of loops. Revised an example's doc to not waste time talking about using a six-sig-fig value for pi (which we no longer do) - it really wasn't relevant, or anything to be proud of; nor did the doc mention its later use.

* Make hellowindow multi display capable on embeddedLaszlo Agocs2014-10-161-2/+14
| | | | | | | | | | | | | | | | | Platforms like eglfs allow a single window per screen. Thus the behavior of --multiple is not suitable since it tries to open multiple windows on the primary screen. Instead, introduce --multiscreen. Add also --timeout to quit the app after 10 seconds. This is essential on platforms that do not have windows with decorations that can be used to close windows. With eglfs' kms/drm hooks, starting with --multiscreen will now show a rotating logo on all connected displays, with some random background color.

* Modernize the OpenGL examplesLaszlo Agocs2014-08-121-24/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change them to use QOpenGLWidget and QOpenGLTexture. Advocate also the usage of VBOs. Hopeless examples, that rely on the fixed pipeline and will not compile or work in ES and dynamic builds, are moved to a "legacy" directory. The documentation pages for these are removed. This long due change avoids the confusion newcomers experience when trying to get started with Qt 5 and OpenGL. hellowindow's behavior is changed to open a single window only by default. The old default behavior, that opened three windows on platforms that supported both MultipleWindows & ThreadedOpenGL, can be requested by passing --multiple. --single is removed since it is the default now. This plays much nicer with drivers that have issues with threading. In addition, say hello to hellogl2. This is the old hellogl example updated to use QOpenGLWidget and OpenGL 2. It also has a mainwindow with multiple (un)dockable widgets containing the OpenGL widgets. This helps testing the behavior when the top-level of the QOpenGLWidget changes and provides a very important example of how to do proper resource management in this case. (must use aboutToBeDestroyed() of the context, since the context goes away and is replaced by a new one on every dock/undock) As a bonus, the logo is now real 3D, no more orthographic nonsense. Launch with --multisample to request 4x MSAA. Launch with --coreprofile to request 3.2 Core. In this particular example the shaders are present in both versions and there is a VAO so the application is functional with core profile contexts.

* Extend QOpenGLFunctions with GL1 functionsLaszlo Agocs2014-03-041-11/+11
| | | | | | | | | | | | | | | | | | This introduces the ability to indirectly invoke all common GL1-GLES2 functions via QOpenGLFunctions. The GL1 functions are not yet resolved, since this would not work anyway when linking to an OpenGL implementation directly. However this may change later but that will be a completely internal change without affecting any public APIs. Also migrate some of the opengl examples to use QOpenGLFunctions for everything. Once dynamic GL loading becomes available on some platforms, these examples should continue to function without any changes since they do not anymore invoke any OpenGL functions directly.

* Rename all QWindow properties that have "window" in themShawn Rutledge2012-11-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | windowTitle, windowModality, windowIcon and so on are named that way to be similar to the ones in QWidget. However QQuickWindow inherits all of the declared properties, and we would like to have shorter property names in QML. If you are working with a Window then it's obvious the title property is the window title. Unfortunately, there must be patches in many other modules which depend on this one. In order to avoid the need to merge them all at the same time, there is also patch https://codereview.qt-project.org/#change,39001 which temporarily adds backwards-compatible accessors, which can be removed after the other modules are able to build without them. We should not rename windowState to state, because in QML, state usually drives the state machine for animation transitions etc. (although QWindow is not an Item, a user might get confused about it).

This is for being able to support adding screens at run-time later on, by connecting it to a signal in QGuiApplication. The QGuiGLContext API has changed a bit, by not sending in all the parameters in the constructor but instead having a create() function. The createPlatformGLContext() factory in QPlatformIntegration takes a QGuiGLContext * instead of a QSurfaceFormat and a share context, similar to how the window and backing store factory functions work. The XCB plugin has experimental support for connecting to multiple X displays simultaneously, creating one or more QScreen for each.

| | | | | | | | | | | | | To enable having a single GL context used for multiple drawables we need to de-couple the context class a bit more from the window class in the plugin API. Now contexts are created stand-alone based on a GL format and a share context, and when calling makeCurrent() a desired surface is specified. This maps well to GLX, EGL, Cocoa, AGL, and WGL, which all support this use case. QWindowContext is renamed to QGuiGLContext, and QWindowFormat is renamed to QGuiGLFormat. We have the ability to introduce a pbuffer or similar other offscreen GL drawable abstraction in the future.
