Hello All,
I am writing a dialog which one of its widget is a gtk.ComboBoxEntry (
let's assume widget in the example below is its instance )
When the user select one of the values from the gtk.ComboBoxEntry I need
to run some calculations that takes a few seconds.
In order to reflect calculation time to the user I want to switch the
mouse pointer to an hour glass and back to arrow what it finish the
calculation.
I use the following code but it doesn't seems to work in a deterministic
way. From time to time it skips the last line and keep the mouse pointer
as an hour glass.
watch = gtk.gdk.Cursor(gtk.gdk.WATCH)
widget.window.set_cursor(watch)
calculation code
widget.window.set_cursor(None)
I would appreciate your advice on the right way to implement this.
Could the calculation code be raising an exception? Try adding some
logging to see whether the last lien is actually being called. You could
also use a try...finally... block to ensure that the last line is
called:
watch = gtk.gdk.Cursor(gtk.gdk.WATCH)
widget.window.set_cursor(watch)
try:
calculation code
finally:
widget.window.set_cursor(None)
