Member Function Documentation

event() [1/2]

bool src_gui_vulkan_qvulkaninstance2::VulkanWindow::event ( QEvent * ev )

inlinevirtual

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.

event() [2/2]

bool src_gui_vulkan_qvulkaninstance2::VulkanWindow::event ( QEvent * ev )

exposeEvent() [1/2]

void src_gui_vulkan_qvulkaninstance2::VulkanWindow::exposeEvent ( QExposeEvent * ev )

inlinevirtual

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.
