hi all,
please help me with little problem [ the big one for me right now :(]
i write little app [ texteditor , who not :) ]
from textview i call window popup with help. [pressing 'a' in test
prog ] and i have 2 questions.
1.) how i disable automatic Tab inserted after pasting text from popup ?
use another key is solution but i want Tab as completer.
2.) it seems to same prob as in 1.) but how i disable moving cursor in
textbuffer when popup window is active and i changing rows in
treeview ? when i change type on WINDOW_TOPLEVEL my treeview has
focus and i cannot write into buffer.
sorry for my noob questions. here is example.
import gtk
class Completer(gtk.Window):
def __init__(self, parent, textview):
gtk.Window.__init__(self, gtk.WINDOW_POPUP)
self.set_size_request(200, 300)
