How to clear the Entry subwidget of Tix Combo box?

[dudeja.rajat]

Hi,

In my combo box taken from Tix, how can I delete item in Entry subwiget?

My case is like this:

I have a check button which when made un-ticked should clear the entry
from combo box (i. anything selected in combo box previously)

I used the following commands:
subEntry = self.cbAnalysisLibVersion.subwidget("entry")
subEntry.delete(0,END)


This does not seem to be working?
