// Class : WindowHandle
|
|
// Description : This object represents a window on the desktop, not
|
|
// necessarily a Panda window. This structure can be
|
|
// assigned to a WindowProperties to indicate a parent
|
|
// window.
|
|
//
|
|
// It also has callbacks so the Panda window can
|
|
// communicate with its parent window, which is
|
|
// particularly important when running embedded in a
|
|
// browser.
|
|
//
|
|
// To create a WindowHandle, you would usually call one
|
|
// of the NativeWindowHandle::make_*() methods,
|
|
// depending on the kind of native window handle object
|
|
// you already have.
