QWindowCreationContext Class

Detailed Description

Active Context for creating windows.

There is a phase in window creation (WindowCreationData::create()) in which events are sent before the system API CreateWindowEx() returns the handle. These cannot be handled by the platform window as the association of the unknown handle value to the window does not exist yet and as not to trigger recursive handle creation, etc.

In that phase, an instance of QWindowCreationContext is set on QWindowsContext.

QWindowCreationContext stores the information to answer the initial WM_GETMINMAXINFO and obtains the corrected size/position.
