Question

Specifying & locking the size of a JPanel

Asked by: KrisM82

Hi all

I have to JPanels, one is slightly smaller than the other by about 5 or 6 pixels, for some reason I cannot set and lock the size of the JPanel so that it doesnt change.


Is there a ways that I can lock it so that the size of the JPanel will never change? I have tried using the seSize(int, int). (Dimension) methods and they dont seem to do anything

any help would be fantastic

thanks kris

Try overriding all the sizing methods such that they'lll only work once (flag them)

 

by: NeutronPosted on 2004-07-22 at 04:35:07ID: 11611245

You could try setting the layout-manager of the parent container to null, and then using the setSize method...

(maybe you will also have to setLocation too)

>>You could try setting the layout-manager of the parent container to null

That will of course affect all other components

Are you having trouble getting the JPanels to be a certain size or is the problem that the user is able to resize them?

 

by: IneednotitlebarPosted on 2004-07-22 at 11:32:09ID: 11615159

from experience, I agree with CEHJ, setting the parent containers layout to null allows you to have full control over where components are.  

In fact, if you have only two panels in a frame (assuming the parent is a frame) it would be quite easy. set the frames layout to null, and use setLocation and setSize to your hearts content to place the panels.  

You could also lock it so that you cant resize the parent too, I believe its setResizable( false )

>>I agree with CEHJ, setting the parent containers layout to null allows ...

That's not me you're agreeing with ;-)

That solution is only applicable if you want to take over the layout for all Components in that Container

GAH, Ok, true that... I agree with whomever said that...  :)
