Thanks Robin,
EVT_SCROLLWIN doesnt seem to be enough - for example moving the cursor up
and down off the page - but I can trap these separately.
If I want the evt_scrollwin handling to allow update to the other window
while dragging the scroll bar I can do a wxYield():
def OnScroll(self,event):
print event
wxCallAfter(self.ScrollAfter, 0) # scroll back to top after initial events
wxYield()
event.Skip()
def ScrollAfter(self,event):
(x,y)=self.CalcUnscrolledPosition(0,0)
self.frame.Change(x,y) #notify other window to move
Unfortunately the CalcUnscrolledPosition is wrong until the mouse is
released (it looks like the previous position)
How would I intercept repainting of the grid.GetGridWindow()?
Cheers,
Andrew

Hi,
I am having trouble intercepting events on a wxGrid control.
I have a grid and another window side by side. I want to "scroll" the
other
window to keep insync with the vertical scroll on the grid window.
I have found I need a combination of many event handlers and liberal use
of
wxCallAfter to update the gfx in the other window to match the contents of
the grid for all possible scrolling methods on the grid.
Isn't EVT_SCROLLWIN enough?
I tried an EVT_PAINT message to catch any redrawing of the grid - but this
was never called when scrolling via mouse or cursors.
The wxGrid is actually composed of several component windows, so they
are the ones getting mouse and paint events, not the main grid window.
YOu can get a reference to the windwo implementing the main part of the
grid with grid.GetGridWindow()
