TExtIntuiMessage

Extended Intuition message structure

Declaration

Source position: intuition.pas line 540

`type TExtIntuiMessage = record`
`eim_IntuiMessage: TIntuiMessage;`		Standard Intuition message
`eim_TabletData: PTabletData;`		Pointer to tablet data
`end;`

Description

All IntuiMessages are now slightly extended. The ExtIntuiMessage structure has an additional field for tablet data, which is usually nil. If a tablet driver which is sending inputevent.IESUBCLASS_NEWTABLET events is installed in the system, windows with the WA_TabletMessages property set will find that eim_TabletData points to the TabletData structure. Applications must first check that this field is non-NULL; it will be nil for certain kinds of message, including mouse activity generated from other than the tablet (i.e. the keyboard equivalents or the mouse itself).

Note

This structure is subject to grow in the future. Making assumptions about its size is a bad idea.
