window sizing trouble

[jeremytaffy]

I have an application that loads in a small window. When a selection is made, I clear the small window, and want to make it full screen sized, with a big button filling most of the screen. I have been able to resize the window, but the button only fills the size of the area that was originally there. I cant figure it out. code included

thanks in advance

i was wondering about a similar thing the other day. I couldnt figre it out either

OK, well i don't know if that helps your problem, but there are some strange thingies in your source:

1) Kill that "final" stuff, as far as i see there is no sense to make anything final in your program. At least not local variables...

2) Don't set layouts to null, simply set it to the layout you need, null layout messes most things up

3) When you want to clear a panel/frame use removeAll(), afterwards add new items to it!

4) Don't write class names (like go) in lower-case, commonly the first letter is upper-case. Just to be fussy

So, my suggestion what could help:
Replace the code of method
public void actionPerformed(ActionEvent e)
with this:

if (rbutton1.isSelected())
{
   Dimension screenSize=Toolkit.getDefaultToolkit().getScreenSize();
   int wdFrame=screenSize.width;
   int hgFrame=screenSize.height;
   frame.setBounds(5, 5, wdFrame, hgFrame);
   frame.removeAll();
   frame.add(yesButton);
   frame.doLayout();   
}
[\code]
If that doesn't help, set the layout of frame in your main method to BorderLayout and add components to the CENTER

thanks for the help. I got it to work by modifying it to this:

if (rbutton1.isSelected()){
Dimension screenSize=Toolkit.getDefaultToolkit().getScreenSize();
int wdFrame=screenSize.width;
int hgFrame=screenSize.height;
frame.setBounds(0, 0, wdFrame, hgFrame);
removeAll();
add(yesbutton);
frame.doLayout();

however, i want to be able to add one more smal cancel button just to the side of big button. i tried adding the button the same way, but it added it over the top as a huge button.
any help would be appreciated
thanks in advance!

did you try using GridBagLayout to work things out? That is very powerful, can do anything you want.

 

[Tschibo]

Don't try GridBagLayout at least you have some REALLY complicated layout to do. I have solved all layout problems w/o it up to now.

How you add the small button to the side depends on how the small button should look like afterwards.

When it's something like

+--------+-+
|        | |
|        | |
|        | |
+--------+-+
[\code]
Then simply use my best friend, the BorderLayout, put the big one in CENTER and the small one in EAST (or WEST for the other side).

But if it shall be not as high, something like this
[code]
+--------+
|        |
|        +-+
|        | |
+--------+-+
[\code]
you should nest to BorderLayouts, like this:
[code]
p1=new Panel(new BorderLayout());
p2=new Panel(new BorderLayout());
p1.add(big, BorderLayout.CENTER);
p1.add(p2, BorderLayout.EAST);
p2.add(small, BorderLayout.SOUTH);
[\code]
Maybe you need some padding stuff, but that should do it
