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.
