Re: [pygtk] Problem with window.set_modal()
Mauro Giacomini wrote: I have a problem with the set_modal function in a pygtk program I'm writing. The situation: I have a main window; when the user clicks on a button, a new window came up for the selection of a particular item in a treeview. When the user confirm the selection with the click on the ok button, this window disappear (destroy) and the interaction return to the main window. But, although I declare the second window such as modal window and transient for main window, the instruction I put in the main window after the call to the second window are executed without waiting the response for the second window. Is there something else to do? Or is there a better approach to a similar situation? Modality itself only prevents user from interacting with other application windows. It doesn't cause application to wait for window response anywhere. If you want to get response now, use gtk.Dialog.run(). Note that GNOME programs are generally not recommended to use modal windows.

There can be some handlers that you don't know of, e.g. GTK+ itself can install some handlers for its own purposes. Then, if you slip some value change in without the corresponding signal, the code behind such handlers can break in unpredictable manner. What you should do instead is to block handlers you don't want to be run during this change and unblock them afterwards (or disconnect and the reconnect again).

Using the hash is fine.
It's currently implemented like this:
static long
pygobject_hash(PyGObject *self)

return (long)self-obj;
}
self-obj is NULL if the object isn't initialized and will return 0.
If it's initialized, self-obj will return the memory address of the
GObject pointer.
This code is unlikely to go away and you can safely depend on it.
