This article was previously published under Q70079 SUMMARY
Although Windows does not have application programming interface (API)
calls to support dragging iconic windows (windows represented by an icon),
calls to MoveWindow() can be used to implement a dragging functionality for
iconic multiple-document interface (MDI) child windows.
However, the icon's title is not in the same window as the icon, so
when the icon is moved, the title will not automatically move with it.
The title is in a small window of its own, so a separate call to
MoveWindow() must be made to place the title window correctly below
the icon.
The information below describes how to get the window handle for the
small title window, so that the appropriate call to MoveWindow() can
be made.
The icon's title window is a window of class #32772. This window is a
child of the MDI client window, and its owner is the icon window.
To get the window handle to the appropriate icon title window for a
given icon, enumerate all the children of the MDI client window,
looking for a window whose owner is the icon.
You can use EnumChildWindows() to loop through all the children of the
MDI client window.
You can use GetWindow(..., GW_OWNER) to check the parent of each
window.
