wxGrid bvackground colours, repainting/refreshing.

wxPython Users

G'day All,
I have a wxGrid in which I am doing some processing on each row/line.

I was hoping I could change the background colours of the cells as they are read and processed.
I did this by just putting this

self.grid.SetCellBackgroundColour(row,col,MYgrey)
self.grid.ForceRefresh()

after each cell was processed successfully

The problem is the window/grid/cells aren't actaully repainted with the new
background colours until the mouse triggers an even on the grid,
so the effect is not really what I had hoped for.

Is there a way to implement this, what is wrong with the logic?

TIA

Do you have any BeginBatch calls that havn't yet had a matching EndBatch call? ForceRefresh doesn't do anything if batch processing is active. If that doesn't help then you could try doing this instead:

  self.grid.GetGridWindow().Refresh()
