Draw zoom rectangle on CompactFramework
Posted: Fri Apr 24, 2009 8:15 pm
Hi,
I am trying to use the zoom features on compact framework.
All I am trying to have is to have the zoom rubber band for the selection i am trying to do.
However, as I drag the mouse around, I don,t see any rubber band, but the zoom functionnality is working fine.
Looking in the source code, I have found this:
and this:
which clearly explains why nothing is displayed: nothing is done...
In my opinion, it is a very bad idea to declare a System.Windows.Forms namespace [Who would have thought such a namespace would be declared inside Steema.TeeChart.Pocket.dll ....], especially if you don't do anything inside the methods... I have been wondering what I was doing wrong for a considerable amount of time before discovering this...
Is there any way to be able to see a rubber band when zooming on compact framework ?
