I HAVE TWO JPANELS named "UI" and "OUTPUTPAGE1" and one JScrollPane in which UI Jpanel is already present ....i want to replace UI Jpanel by OUTPUTPAGE1 JPanel by a mouseclick event
HELP!!

[Rob Camick]

Way too much code to post. In the future post a proper SSCCE when yo uask a question.

i want to replace UI Jpanel by OUTPUTPAGE1

scrollPane.setViewportView( outputPage1 );

hey Rob ,
i know i have posted way too much code .... in learning phase ....
i have already tried this

jsp.setViewportView(op1)

....but not success



anywhere else i could be going wrong....maybe adding of mouselistener or anywhere else??

[Rob Camick]

in learning phase ....

And that is way I suggested you need to start with an SSCCE.

Create a simple program that does what you need. Prove to yourself that it indeed is only a single line of code that is required to replace a component in a scrollpane.

Then once you get it working in a simple program you look to what is different in your real program. Like I said we don't have time to read through all that code.

maybe adding of mouselistener

Thats easy to check. Just add a println(..) statement in the listener to see if the code is executed.

or anywhere else??

A common problem is having two variable reference different scrollpanes. So maybe you have a class variable and an instance variable of the same name. Get rid of the instance variable.

i tried your trick of writing the minimal possible code which does what i want it to ....and it has worked ....would be posting a solution asap of my original problem so that i can contribute to this forum cheers

There is no need to revalidate() the viewport.
