Source position: intuition.pas line 4093
function DoGadgetMethodA( |
gad: pGadget; |
win: pWindow; |
req: pRequester; |
message: tMsg |
):LongWord; |
gad |
|
An abstract pointer to a boopsi gadget |
win |
|
window gadget has been added to using AddGList() or AddGadget() |
req |
|
For REQGADGETs, requester containing the gadget |
The object does whatever it wants with the message you sent, which might include updating its gadget visuals. The return value is defined per-method.
Same as the DoMethodA() function, but provides context information and arbitration for classes which implement custom Intuition gadgets.
You should use this function for boopsi gadget objects, or for "models" which propagate information to gadgets.
Unlike DoMethodA(), this function provides a TGadgetInfo pointer (if possible) when invoking the method. Some classes may require or benefit from this.
Note: This function invokes the specified method with a TGadgetInfo derived from the Window and Requester pointers. The TGadgetInfo is passed as the second parameter of the message, except for OM_NEW, OM_SET, OM_NOTIFY, and OM_UPDATE, where the TGadgetInfo is passed as the third parameter.
Implementers of new gadget methods should ensure that the TGadgetInfo is the second long-word of their message!
