I added the scrollbar in the resource (.rcp) file
SCROLLBAR ID ScrollList AT ([EMAIL PROTECTED]
[EMAIL PROTECTED] 7 110) VALUE 0 MIN 0 MAX 0 PAGESIZE 0
and in the .c file i added the following code
static Boolean MainFormHandleEvent(EventPtr event)
{
ScrollBarType * ScrollBarPtr;
......some code here......
... some switches here.....
case sclRepeatEvent:
{
newval = event->data.sclRepeat.newValue;
MainFormInit(form,MainStartIndex+newval,MainEndIndex);
FrmDrawForm(form);
handled = false; //Handled should be set to false
}
break;
}
Now at first if i wanted the scrollbar to be hidden i
just did
FrmHideObject(form,FrmGetObjectIndex(form,ScrollList)).
The scrollbar return 2 types of values one is the new
value it went to and the other on which it was
prevously at. Now from these values i calculated which
records to show in the table . MainFormInit method
does that displaying accordingly.
Hope this helps
