Hello again,
I have a problem with GtkCellRendererCombo, for which I did not find a
solution yet.
I try to use editing-started signal on that renderer to update combobox
model based on current selection in my treeview. But it segfaults out
when I try to receive the currently selected value from my treeview
treemodel.
Segfault stacktrace: http://pastebin.com/m4694e64b
TreeView creation: http://pastebin.com/m4da78675
editing-started-callback: http://pastebin.com/mcdb04be
Note: here is the segfault in line 20 (gtk_tree_model_get), some things
that drawed my attention: editable is 0x0, path is "0:0" (even if my
selected line is the second one in my treeview)
Model update/creation: http://pastebin.com/m3f5f52b7
My questions:
- Does anybody find an error why it segfaults?
- Is my solution the prefered one to do such tasks? (I also tried to use
cell_data function to update the combobox, this way was working to some
extend, (combo got values, getting selection works) but seems to cause
massive recalculating so it even does no longer support drag'n'drop in a
second application part.)
Greetings,
Christoph Hartwig
