Hi,
I try to get all selected cells in a wxGrid and normal selections work
quite well.
However, when I de-select a cell after selecting a row that contains
this cell, I do not get any update on the GetSelect... methods that are
shown below in the code. The unselected cell is correctly displayed
unmarked in the grid. The behavior is identical if columns
instead of rows are selected.
The wxPython demo does not display any selection-specific event (other
than OnClick) in this case.
For example, when I select row 2 and then Ctrl-Click on the first cell
inside row 2, the highlighting disappears but I do not get any
selection-related events. The functions that I use for getting the
selection do not yield updated values.
How do I catch these unselected cells or how do I get a list of
all cells in the range?
I am using wxPython 2.8.7.1 with python 2.5 on Linux (wxGTK).
Best Regards
Martin
