[wxPython-users] a few questions about wx.Grid

[Vern Muhr]

Chris,

Thanks for the very quick reply! SetCellHighlightPenWidth(0) eliminated the cursor, as long as it is called after the grid has been populated. I don't really understand what the real prequisite is, but I get an exception if I set it too soon.

I was also able to hide a column if:
1. I call SetColMinimalAcceptableWidth(col, 0)
2. I later call SetColSize(col,0)
3. finally, renderer.GetBestSize() returns a with of 0 for cells in the hidden column.

Thanks again for the help,

Vern

SetCellHighlightPenWidth(0). Note that the cursor will still be
"present" and that may affect the way your user interacts with the
grid unless you provide overridden behavior. For example, arrow keys
to navigate may not be intuitive (since they'll be moving the
invisible cursor, not scrolling the grid).

Set them to 0 height/width.

Congratulations, I look forward to seeing it.
