Hi,
I have a QListView, I also have a separate checkbox to do selectAll,
deselectAll functionality, and It's working. but I am missing one thing,
when I do selectAll, then deselect one item, The SelectAll checkbox should
be cleared. I have been trying to figure out a way to do that but can't
find the right way to do It.
Here is what I have done so far:
I have conntected the listView.selectionModel() 'selectionChanged' signal
to toggle_groups_checkbox, In there I try to print the count of deselected
items, and if it's more than 0 I clear the checkbox, but printing the count
of deselected_items is not accurate, when I do selectAll it prints many
values, one of them deselectedItems is 1... that would make me clear the
checkbox, which is wrong. I think there is a better way to do that, so any
guidance would be appreciated.
self.connect(self.ui.listView_gateway_groups.selectionModel (),
SIGNAL("selectionChanged(const QItemSelection&,const QItemSelection&)"),
self.toggle_groups_checkbox)
def toggle_groups_checkbox(self, set_selection, clear_selection):
print set_selection.count()
print clear_selection.count()
