hi everybody,
a have a simple ??
i'm working on a chat application. my message displaying area is a canvas.i have added scroll-bars to it using scroll-pane
"sp = new ScrollPane(ScrollPane.SCROLLBARS_ALWAYS);"
now what i want is the scrollbars should adjust automatically to display the last message and also i should be able to adjust them
manually so that i can view the previous messages.
i have tried setScrollposition() it works well also but then i'm not able to adjust scrollbars manually.
this interface is in AWT.
please tell me a solution.its a bit urgent.
thankx and regards

Hi Asheet,
I can not help you with the problem. I have never attempted it so I have no clue as to how to do it.
Sorry,
Manfred

Perhaps you would get a better response if you used a more appropriate subject!

use this code
txtArea.scrollRectToVisible(new Rectangle (0,txtArea.getHeight()-2,1,1));

You use a low-level component, you'll need a low-level solution.
In other words, when the scrollbar moves, you'll have to redraw the affected parts of the canvas.
For smooth scrolling, you'll need to bit-blit. It's simpler to scroll line-by-line by rerendering the strings, but that makes for jerkier operation.
