GetWindowClass
Obtains the class of a window.
pascal OSStatus GetWindowClass (
WindowPtr window,
WindowClass *outClass);
- window
- A value of type WindowPtr . Pass a pointer to the window whose class you wish to obtain.
- outClass
- A pointer to a value of type WindowClass . On return, this value identifies the class of the specified window. See Window Class Constants for a list of possible window classes. If the window was not originally created using the function CreateNewWindow , the class pointed to by the outClass parameter is always identified by the constant kDocumentWindowClass .
- function result
- A result code. See Result Codes.
DISCUSSION
A window's class categorizes the window for purposes of display (that is, both the window's appearance and its display ordering) and tracking. A window's class cannot be altered once the window has been created.
