Hello,
I'm having trouble getting checkboxes to work properly when I use a
sub-classed QDirModel and CheckStateRole in data(). The app's
checkboxes don't appear to respond to mouse-clicks. (Although their
states are changing, as I've verified in the model.)
If anyone has a moment to execute and/or review the small code example
I've copied below, I'd greatly appreciate it.
Thanks in advance!
Scott
