◆ event() [1/3]

bool RasterWindow::event ( QEvent * ev )

protectedvirtual

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.

Definition at line 64 of file rasterwindow.cpp.

Here is the call graph for this function:

◆ exposeEvent() [1/3]

void RasterWindow::exposeEvent ( QExposeEvent * ev )

protectedvirtual

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.

◆ paintEvent()

void RasterWindow::paintEvent ( QPaintEvent * ev )

inlineprotectedvirtual

The paint event (ev) is sent by the window system whenever an area of the window needs a repaint, for example when initially showing the window, or due to parts of the window being uncovered by moving another window.

The application is expected to render into the window in response to the paint event, regardless of the exposed state of the window. For example, a paint event may be sent before the window is exposed, to prepare it for showing to the user.
