Mark,
I use Palm Object Library and ran into the same problem. I use the default
font so some of the items are hard coded but the code below now causes the
entire row to be selected. Basically you need to check that the penDown is
after the first 11 pixels, for the default font, and if it is queue a
tblEnterEvent.
RectangleType rectTable;
GetBounds(rectTable);
// see if the point is in the table
if( RctPtInRectangle(pEvent->screenX, pEvent->screenY,
&rectTable) )
{
Int16 screenY = pEvent->screenY - rectTable.topLeft.y;
// calulate which row we are in
// only send the tblEnterEvent if after the first 11 pixels, using
standard font so
// it's hardcoded
if( screenY % m_wRowHeight > 11 )
{
Int16 row = (screenY / m_wRowHeight);
// send a table enter event
EventType event;
MemSet(&event, sizeof(event), 0);
event.screenX = pEvent->screenX;
event.screenY = pEvent->screenY;
event.eType = tblEnterEvent;
event.data.tblEnter.tableID = CTable::GetObjectID();
event.data.tblEnter.pTable = GetTablePtr();
event.data.tblEnter.row = row;
event.data.tblEnter.column = 0;
// queue it
EvtAddEventToQueue(&event);
}
}
else
CGrid::HandleEvent(pEvent, bHandled, bResult);
Hope this helps!
