| | | | | | | | | | | | | | | | | | Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to qt.io. Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination. New header.LGPL-COMM taken in the use file which were using old header.LGPL3 (src/plugins/platforms/android/extract.cpp) Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license combination Change-Id: I6f49b819a8a20cc4f88b794a8f6726d975e8ffbe Reviewed-by: Matti Paaso <matti.paaso@theqtcompany.com>
* Make hellowindow multi display capable on embeddedLaszlo Agocs2014-10-161-1/+3
| | | | | | | | | | | | | | | | | 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 Agocs2014-08-121-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Examples: Add Q_DECL_OVERRIDE to overridden functionsOlivier Goffart2014-07-151-2/+2
| | | | | | | | | | | | | | | | | | Q_DECL_OVERRIDE (which expands to 'override' for supported compiler) helps to declare the intent (that it is an overridden function) and force compilation error when there is no such virtual function in the base class. The examples should show the best practice of having it, as it may save the programmer quite some time in case of change of API or typo in the function name or arguments. This change was done automatically with clang-modernize -add-override -override-macros And fixed MSVC compilation by removing inline for TorrentViewDelegate::paint Change-Id: Ice66ae93fae571266f908703d5b8892b2c1ebb1a Reviewed-by: Jędrzej Nowacki <jedrzej.nowacki@digia.com>
* Improved robustness of threaded rendering in hellowindow example.Samuel Rødal2013-04-251-11/+14
| | | | | | | | | | | | Previously resizes along with the animation was implemented using queued signals and slots, potentially causing a huge lag between the size of the window and the rendered contents. Now the animation is always driven by the rendering thread and is triggered based on the window's isExposed() status.

* QWindowContext / QWindowFormat refactor.Samuel Rødal2011-06-101-10/+30
| | | | | | | | | | | | | 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.
