Canvas Problems

[SmallProgram]

Hello Friends,
Now that I have got lot of help from this site Iam feeling very much at Independence to ask you people silly doubtsalso.Please bear withme and answer my questions.
Now My question is that I want to edit the objects that are generated at runtime on a canvas.What I mean is that If I draw line or a oval or a rectangle how to identify them after a series of events and how to edit them i.e how to change their properties.
I mean can we get their identification (ids) and can we use the configure tag.
Please Answer me
Thanks in Advance.

When you create objects on the canvas, the "create" command returns the id: set cid1 [.c create line $x1 $y1 $x2 $y2]
Then you can change the configuration:

pathName itemconfigure tagOrId ?option? ?value? ?option value ...? Bob Rashkin

You can also apply tags to canvas items, and then manipulate them later by using the tag names instead of the IDs. For example:

[tt]pack .c
.c create rectangle 20 20 120 120 -tags fred
.c create oval 150 30 190 100 -tags {fred barney}
.c itemconfigure barney -fill red -outline
.c move fred 5 50[/tt] - Ken Jones, President
