title: Adding browse function to button -Python
body: <p>I have a button in my code:</p>
  
  <pre><code>self.add_bt = Gtk.Button()
  self.add_bt.set_label(_("Choose from computer"))
  
  
  vbox.pack_start(self.add_bt, False, False, 0)
  </code></pre>
  
  <p>I want to include FileChooser function on clicking this button.</p>
  
  <pre><code>dlg = Gtk.FileChooserDialog()
  dlg.show()
  </code></pre>
  
  <p>What I am trying to do is, on clicking the button labelled "Choose from computer" I want the browse window to open.
  Then get the added file included in place of current image.</p>
