Thanks for the suggestion. I tried using a Pmw.ComboBox, but I've run
into essentially the same problem. If I bring up the selection list
on a keypress, then the selection takes the focus and further input no
longer goes to the entry of the ComboBox. However, if I set the focus
to the entry after bringing up the selection list, I can at least
continue inputting to the entry, even though the selection list menu
gets placed behind the entry. This is not desirable behavior, but at
least it is closer. Any idea how to bring the menu to the forefront
without the entry losing focus? The following demo demonstrates the
issue:
import Tkinter
import Pmw
class demo:
def __init__(self, parent):
self._search_bar = Pmw.ComboBox(parent,
label_text = 'Register Mnemonic',
labelpos = 'w', entry_width = 60)
self._search_bar.pack(padx = 20, pady = 20)
self._search_bar._entryfield.component('entry').bind('<Key>',
self._suggest_text, add = '+')
def _suggest_text(self, event):
curr = self._search_bar._entryfield.getvalue() +
repr(event.char)[1]
self._search_bar._list.setlist([curr + '_0', curr + '_1', curr
+ '_2'])
self._search_bar._postList(event)
self._search_bar._entryfield.component('entry').focus_set()
print curr
if __name__ == '__main__':
root = Tkinter.Tk()
root.title('A Problem')
demo(root)
root.mainloop()
