Hi Paul,
I've just started using this control too, and found that same problem.
Carlos Alloatti is already aware of this problem, and for this moment, I did
the following to fix this small bug.
Carlos is not available this week, and he promised to send a new version as
soon as he gets back.
For now, you can do one of the following solutions:
1 - Create a new method, "ResetScrollBars", and add the following code:
If This.ControlCount > 0 And This.Controls(1).BaseClass = [Image]
With This.Controls(1)
This.nOriginalWidth = .Width
This.nOriginalHeight = .Height
This.nZoomIndex = This.nDefaultZoomIndex
ShowScrollBar(This.nHCtlHwnd, SB_CTL, 0)
ShowScrollBar(This.nVCtlHwnd, SB_CTL, 0)
This.ctl32_Resize()
If This.ctlVEnabled Then
This.ctlVVAlue = 0
Endif
If This.ctlHEnabled Then
This.ctlHValue = 0
Endif
Endwith
This.ctlZoom = 100
Endif
So, after you change the WIdth or Height properties of your SContainer, just
call the above method, and it's done.
2 - The better way, and probably how it will be fixed:
a - in method Ctl32_BindEvents, add the following code at the end;
*!* Control Resizement
Bindevent(This.Controls(1), Width, This, EvtHandler_Size, 1)
Bindevent(This.Controls(1), Height, This, EvtHandler_Size, 1)
b - Create a new method, and call it "EvtHandler_Size" and put this code in
it:
With This.Controls(1)
This.nOriginalWidth = .Width
This.nOriginalHeight = .Height
This.nZoomIndex = This.nDefaultZoomIndex
ShowScrollBar(This.nHCtlHwnd, SB_CTL, 0)
ShowScrollBar(This.nVCtlHwnd, SB_CTL, 0)
This.ctl32_Resize()
If This.ctlVEnabled Then
This.ctlVVAlue = 0
ENDIF
If This.ctlHEnabled Then
This.ctlHValue = 0
ENDIF
ENDWITH
This.ctlZoom = 100
This way, the control will automatically update its scrollbars when width or
height are changed.
Hey Mal, I've already put all those codes
What do you think of this solution ?
Regards
Cesar
