Question

Consider this Python program which uses PyGtk and Hippo Canvas to display a clickable text label. Clicking the text label replaces it with a Hippo CanvasEntry widget which contains the text of the label.

import pygtk pygtk.require('2.0') import gtk, hippo  def textClicked(text, event, row):     input = hippo.CanvasEntry()     input.set_property('text', text.get_property('text'))     parent = text.get_parent()     parent.insert_after(input, text)     parent.remove(text)  def main():     canvas = hippo.Canvas()     root = hippo.CanvasBox()     canvas.set_root(root)      text = hippo.CanvasText(text=u'Some text')     text.connect('button-press-event', textClicked, text)     root.append(text)      window = gtk.Window()     window.connect('destroy', lambda ignored: gtk.main_quit())     window.add(canvas)      canvas.show()     window.show()      gtk.main()  if __name__ == '__main__':     main() 

How can the CanvasEntry created when the text label is clicked be automatically focused at creation time?

Answer 1

Underneath the CanvasEntry, there’s a regular old gtk.Entry which you need to request the focus as soon as it’s made visible. Here’s a modified version of your textClicked function which does just that:

def textClicked(text, event, row):     input = hippo.CanvasEntry()     input.set_property('text', text.get_property('text'))     entry = input.get_property('widget')     def grabit(widget):         entry.grab_focus()     entry.connect('realize', grabit)     parent = text.get_parent()     parent.insert_after(input, text)     parent.remove(text)
