Detailed Description

Traps LButtonDn events.

The only method that is overridden by this class is LButtonDn; this is to create a picture-based button which can use Mac PICT or Windows BITMAP resources rather than just icons as in the other buttons in the widget set. The implementation is quite sparse in that there are only two different pictures for the selected and uselected states. There is none of the sophistication of the real iconic buttons such as being able to display a highlighted state when the end-user is clicking on the button.

DV_Note: As a widget eventhandler this should now derive from DVControlEventHandler rather than CEventHandler

Member Function Documentation

bool16 PicIcoPictureWidgetEH::LButtonDn ( IEvent *  e )

virtual

Handle left button down events. Change the data model, and also change the picture displayed. This is because there is no platform peer that knows how to change its visual representation so we have to do it ourselves.

Parameters

e	event of interest.

Reimplemented from DVHostedWidgetEH.
