Is there an easy way to make the label on a button reflect the sate of the button. For exampl how would you make a button that says On when pressed and Off when released?

Hi Todd,

In python my code to change the picture on the button, in fact i have a 3 state button :
Red = external emergency, Orange = internal emergency, Green = machine on.
self.widgets.machine_on_button.set_image(self.widgets.red)
self.widgets.machine_on_button.set_image(self.widgets.green)
self.widgets.machine_on_button.set_image(self.widgets.orange)

In your case the basic code can be : Togglebutton1.set_image(red)
My pictures are located in share/linuxcnc, this because this is in the python code :
imagedir = os.path.join(BASE, "share", "linuxcnc")

In glade you can attach a picture to a button. In your case a ON picture and a OFF picture.


Good luck !!

It you have problem's post your python code and glade file.

If you separate this button in the GNU image manipulation program, it cerntainly will work.
You can make very beautifull screen desig's with this feature.


If you want to make a black screen design :
self.settings = gtk.settings_get_default()
self.settings.set_property("gtk-theme-name", "Adwaita-dark")

Hhaa.. whoehoe.
I have never tried this. But indeed. It's the most easyest way. Perfect.
