I have a GUI which shows 640x480 video frames from a firewire camera. I've
gotten a request to allow the user to zoom in on a particular part of the image
if they choose; the camera doesn't have a zoom feature, so this wouldn't give
any better resolution, but might make things easier to see anyw
I have a tool bar containing several GtkRadioToolButtons. Clicking on them
works fine. However, I'm trying to figure out how I can activate one of them
programatically.
My first guess was to do
gtk_widget_activate(GTK_WIDGET(radiobutton));
but that didn't work; gtk_widget_activate returned FALSE
