Window Definition State-Changed Constant

If you implement a custom window definition function, when the Window Manager passes the kWindowMsgStateChanged message in your window definition function's message parameter it may also pass a value in the param parameter with one or more bits set to indicate what part of the window's state has changed. You may use the following mask to test this value. For a description of the kWindowMsgStateChanged message, See Window Definition Message Constants.



 
enum {

    kWindowStateTitleChanged        = (1 << 0)

};

Constant description

kWindowStateTitleChanged: If the bit specified by this mask is set, the window's title has changed.
