Append Results to ListBox

Jun 28th, 2008

Hi,

I have 2 modules, grepforapp.py and myApp.py. Basically i'm trying to make a 'search' utility. myApp makes the UI with one textbox for taking input, start button and a list box which displays the file names where the pattern was found.
grepforApp walks through the dir tree and searches the pattern in each file. In my previous code i used to read and store everything and then would display the results in one shot. Then i changed the code to call the grepforapp.search in a loop and try to display the results as they come for each dir. but this is not happening. If you see the code i'm doing a ListBox.Append in a loop but still the final result is shown in one shot and not in steps. Can anyone see what's wrong with the code?

myApp module

Take a look at the control variables section at the following link. A control variable can be linked to several widgets and will update the widget automatically. http://infohost.nmt.edu/tcc/help/pubs/tkinter/
