Hi!
I am trying to write a simple code to let the user change the
accelerators associated to actions during the execution. I set up a
Gtk::TreeView with Gtk::CellRendererAccel to edit and render the
accelerators. I am able to receive the emitted signals however I got
strange results on modification like being unable to modify the accels
for compile time associated actions or multiple slots associated to a
single accel. In my application I use a Gtk::ActionGroup (I put it
together with the TreeView related thing in a single class) and a
Gtk::UIManager to which I add the Gtk::ActionGroup and from which the
AccelGroup is extracted and passed to the main window.
I saw in action some things i could undo for instance disconnecting for
a signalproxy but there seem not to be a disconnect() function. I do not
really know about all that signal/slot proxys.
I send you a copy of the code i use. Thanks a lot for your
comments/ideas/...
