Description
Callback structures are used to pass platform-specific information. The NPSetWindowCallbackStruct object, allocated by the browser, contains information required for the ws_info field of an NPWindow.
The NPP_SetWindow() function passes a pointer to this structure to the plug-in. The structure is valid for the lifetime of the NPWindow, that is, until NPP_SetWindow() is called again or the instance is destroyed.
The type field of this structure always contains NP_SetWindow. The remaining fields are Standard X Toolkit attributes of the top-level shell window in the browser window hierarchy.
