PyGTK - Frame Class

---

 Frame class is a subclass of the gtk.Bin class. It draws a decorative border around the child widget placed in it. The frame may contain a label whose position may be customized.

A gtk.Frame object is constructed with the help of the following constructor −

frame = gtk.Frame(label = None)

The following are the methods of the gtk.Frame() class −

• set_label(text) − This sets the label as specified by text. If None, the current label is removed.
• set_label_widget() − This sets a widget other than gtk.Label as label for frame.
• set_label_align(x, y) − This sets the alignment of the frame's label widget and decoration (defaults are 0.0 and 0.5)
• set_shadow_type() − This sets the frame's shadow type.

The possible values are −

• gtk.SHADOW_NONE
• gtk.SHADOW_IN
• gtk.SHADOW_OUT
• gtk.SHADOW_ETCHED_IN
• tk.SHADOW_ETCHED_OUT

The following code demonstrates the functioning of the Frame widget. A group of three objects of gtk.RadioButton is placed in an HButtonBox.

btn1 = gtk.RadioButton(None,"Degree")
btn2 = gtk.RadioButton(btn1,"P.G.")
btn3 = gtk.RadioButton(btn1,"Doctorate")
hb = gtk.HButtonBox()
hb.add(btn1)
hb.add(btn2)
hb.add(btn3)

In order to draw border around the box, it is placed in a Frame widget, and it is added to the toplevel window.

frm = gtk.Frame()
frm.add(hb)
self.add(frm)

Example

Observe the following code −

import gtk
class PyApp(gtk.Window):
   def __init__(self):
      super(PyApp, self).__init__()
      self.set_title("Frame Demo")
      self.set_default_size(250, 200)
      self.set_border_width(5)
      frm = gtk.Frame()
      hb = gtk.HButtonBox()
      btn1 = gtk.RadioButton(None,"Degree")
      hb.add(btn1)
      btn2 = gtk.RadioButton(btn1,"P.G.")
      hb.add(btn2)
      btn3 = gtk.RadioButton(btn1,"Doctorate")
      hb.add(btn3)
      frm.add(hb)
      frm.set_label("Qualifications")
      self.add(frm)
      self.connect("destroy", gtk.main_quit)
      self.show_all()
      if __name__ == '__main__':
PyApp()
gtk.main()

The above code will generate the following output −
