Member Function Documentation
◆ event()
|
overrideprotectedvirtual |
Override this to handle any event (ev) sent to the window. Return true if the event was recognized and processed.
Remember to call the base class version if you wish for mouse events, key events, resize events, etc to be dispatched as usual.
Reimplemented from QWindow.
Reimplemented in Window, Window, Window, Window, Window, and Window.
Definition at line 100 of file openglwindow.cpp.
Here is the call graph for this function:
◆ exposeEvent()
|
overrideprotectedvirtual |
The expose event (ev) is sent by the window system when a window moves between the un-exposed and exposed states.
An exposed window is potentially visible to the user. If the window is moved off screen, is made totally obscured by another window, is minimized, or similar, this function might be called and the value of isExposed() might change to false. You may use this event to limit expensive operations such as animations to only run when the window is exposed.
This event should not be used to paint. To handle painting implement paintEvent() instead.
A resize event will always be sent before the expose event the first time a window is shown.

overrideprotectedvirtual |
This virtual function is called whenever the window contents needs to be painted. Reimplement it in a subclass.
There is no need to call makeCurrent() because this has already been done when this function is called.
Before invoking this function, the context and the framebuffer, if there is one, are bound, and the viewport is set up by a call to glViewport(). No other state is set and no clearing or drawing is performed by the framework.
- Note
- When using a partial update behavior, like
PartialUpdateBlend, the output of the previous paintGL() call is preserved and, after the additional drawing perfomed in the current invocation of the function, the content is blitted or blended over the content drawn directly to the window in paintUnderGL().

Here is the caller graph for this function:
◆ resizeGL()
|
overrideprotectedvirtual |
This virtual function is called whenever the widget has been resized. Reimplement it in a subclass. The new size is passed in w and h.
- Note
- This is merely a convenience function in order to provide an API that is compatible with QOpenGLWidget. Unlike with QOpenGLWidget, derived classes are free to choose to override resizeEvent() instead of this function.
- Avoid issuing OpenGL commands from this function as there may not be a context current when it is invoked. If it cannot be avoided, call makeCurrent().
- Scheduling updates from here is not necessary. The windowing systems will send expose events that trigger an update automatically.

- initializeGL(), paintGL()
