/*
|
|
OcctWindow class implements Aspect_Window interface using Qt API
|
|
as a platform-independent source of window geometry information.
|
|
A similar class should be used instead of platform-specific OCCT
|
|
classes (WNT_Window, Xw_Window) in any Qt 5 application using OCCT
|
|
3D visualization.
|
|
|
|
With Qt 5, the requirement for a Qt-based application to rely fully
|
|
on Qt public API and stop using platform-specific APIs looks mandatory.
|
|
An example of this is changed QWidget event sequence: when a widget is
|
|
first shown on the screen, a resize event is generated before the
|
|
underlying native window is resized correctly, however the QWidget instance
|
|
already holds correct size information at that moment. The OCCT classes
|
|
acting as a source of window geometry for V3d_View class (WNT_Window, Xw_Window)
|
|
are no longer compatible with changed Qt behavior because they rely on
|
|
platform-specific API that cannot return correct window geometry information
|
|
in some cases. A reasonable solution is to provide a Qt-based implementation
|
|
of Aspect_Window interface at application level.
