POupdate a gtk.VBox dynamically
text
Body
copied!<p>I have been using this website pretty often in order to solve small issues that I have while programming in Python. This time, somehow I could not find a suitable solution for my situation. So, here is my problem:</p> <p>I want to dynamically add entries to a gtk.VBox widget. The problem is that it doesn't work the way I want it to work. I simply have a button, whose action is to add an additional widget to a VBox. Unfortunately the widget doesn't appear on the window. I guess, I have to add something like a repaint function call, but I didn't find anything like that. Here is a sample code, showing my problem:</p> <pre><code>import gtk class DynamicVbox: def __init__(self): self.window = gtk.Window(gtk.WINDOW_TOPLEVEL) self.window.connect("destroy", self.close_application) self.window.set_size_request(400,320) #a hBox to put the button and the dynamic vBox hBox = gtk.HBox(False, 0) addButton = gtk.Button("add checkbox") addButton.connect("clicked", self.AddCheckButton) self.vBox = gtk.VBox(False, 0) self.vBox.pack_start(gtk.CheckButton("CheckButton"), True, True, 1) hBox.pack_start(self.vBox, True, True, 5) hBox.pack_end(addButton, False, False, 5) self.window.add(hBox) #start gtk self.window.show_all() gtk.main() def AddCheckButton(self, button): self.vBox.pack_start(gtk.CheckButton("CheckButton"), True, True, 1) print "adding checkbox..." def close_application(self, widget): gtk.main_quit() # run it a = DynamicVbox() </code></pre> <p>A appreciate any help. Thanks in advance.</p>
