Detailed Description

Window creation code.

This struct gathers all information required to create a window. Window creation is split in 3 steps:

\list

• fromWindow() Gather all required information
• create() Create the system handle.
• initialize() Post creation initialization steps. \endlist

The reason for this split is to also enable changing the QWindowFlags by calling:

\list

• fromWindow() Gather information and determine new system styles
• applyWindowFlags() to apply the new window system styles.
• initialize() Post creation initialization steps. \endlist

Contains the window creation code formerly in qwidget_win.cpp.
