Hello,
I'm having a little problem with editable cells: I have a validity
check for data entered into a editable cell, and if it fails, I
want to give the user another try to enter something into that
same cell.
To get the focus to the previously edited cell again after showing
an error message, I use TreeView::set_cursor with the last
parameter start_editing set to true (while in the signal handler
for signal_edited of the cell renderer).
The problem is that, when confirming the input by clicking
somewhere outside the cell, the UI gets messed up: the entry for
the edited cell is there as it should (and its content is reset as
it should), but can't be confirmed or aborted anymore. I get the
following error message on the command line:
Gtk-CRITICAL **: gtk_container_remove: assertion
'gtk_widget_get_parent (widget) == GTK_WIDGET (container) ||
GTK_IS_ASSISTANT (container)' failed
Is it just not allowed to use set_cursor while handling the
confirmation of editing a cell or is this a bug I should file?
I can confirm that the same thing happens with one of the example
programs in the gtkmm tutorial,
https://git.gnome.org/browse/gtkmm-documentation/tree/examples/book/treeview/editable_cells
If the input in the cell is finish by pressing Enter, no critical
message is printed. If the input in the cell is finish by moving to
another cell, the critical message is printed.
It looks like a bug, but I don't know if it's a gtkmm bug or a gtk+
bug.
