hi,
i want to use scrollbar for a canvas.
can someone please tell me how to do this


Create a frame, and grid a canvas and two scrollbars within it.

Define the visible size of the canvas via -width and -height, and the overall size with the -scrollregion.

Tie the two scrollbar's events to the canvas using the -xscrollcommand and -yscrollcommand on the canvas.

Set the highlight thickness and border widths to 0 in order to avoid them occupying any of the visible canvas area.

could u pls provide me any examples for doing that..
because i am facing problems while providing the options for canvas.

do i need to use the grid command fro placing the canvas and scrollbar on the frame..

I don't have an example that's within my copyright to reproduce here, but there is a good example in "Practical Programming in Tcl and Tk" (see http://www.wellho.net/book/0-13-022028-0.html) on page 474.  The best example I could find online (I've just had a quick search - I'm sure there are more) is at http://www.usenix.org/publications/login/2002-06/pdfs/flynt.pdf

And, yes, you place the scollbar and canvas on the frame with the grid command.

don'y mind, but, now could you please tell me how grid them together in a  canvas.
because i haven't used grid command in tk till now..
but i have an urgency to complete my work .
so would be a great favour from your side if u could please help me in this topic.

THANKS IN ADVANCE

I'm just about to leave home to give a training course, so much as I would like to do you the great favour, I can't at the moment. The two references in my previous answer both include worked examples, including the use of grid. One of the references is online and available for you to read.

A previous answer at http://www.wellho.net/forum/Assistance/Answers-on-Opentalk.html may also help give you some further insite into what I we can provide here, and the timescale put on answering.

it's ok thank you.
i got it solved without using grid..

thank you once again..
