Function InitWrapperWindow

window.go:716–734

InitWrapperWindow initializes a window that wraps (embeds) another window. Calling this method is necessary, if you want to be able to override the WndProc method of the embedded window. The embedded window should only be used as inseparable part of the wrapper window to avoid undefined behavior.
