* registered window messages. The name passed to
|
||
* RegisterWindowMessage() is gtk-win32-embed:%d, with %d being the
|
||
* numeric value of an GtkWin32EmbedMessageType enum. Each message
|
||
* carries the message type enum value and two integers, the “wparam”
|
||
* and “lparam”, like all window messages.
|
||
*
|
||
* So far all the window messages are posted to the other
|
||
* process. Maybe some later enhancement will add also messages that
|
||
* are sent, i.e. where the sending process waits for the receiving
|
||
* process’s window procedure to handle the message.
