include pGUI.e
atom func = IupGetCallback(Ihandle ih, string name) |
Description: |
Returns the callback associated to an event.
ih: identifier of the interface element. name: name of the callback. Returns: the callback or NULL if there is none. |
Notes: |
This function replaces the deprecated combination:
IupGetFunction(IupGetAttribute(ih, name)) IupGetCallback also returns the correct callback if an event was associated using IupSetFunction and IupSetAttribute, so old applications work normally. (Note that IupGetFunction has been renamed/wrapped as IupGetGlobalFunction() in pGUI, hence the red/invalid colour.) |
