Hi, everyone!
I'm making an Gtk application, which has a table (GtkTreeView), and a
customized canvas widget providing graphical view, both corresponding to same
data (GtkTreeModel).
I want to synchronize the selection state between the table and the canvas.
When people change the selection in table, or click on an item in canvas, both
of them should change their selection: select to corresponding row, and
highlight on corresponding item.
Now the problem comes: GtkTreeSelection emits the 'changed' signal, no matter
it is caused by mouse click or by program. If I organize callbacks in the way
below, the callback will fall into a cycle.
on_table_change {
change_model
}
on_canvas_item_change {
change_model
}
on_model_change {
change_table_selection
change_item_rendering
}
So, how should I organize those callbacks? Thanks a lot!!!
