Keeping a Java App. Open but Closing One of the Windows
 
Hi:

I made a java app. (with 3 windows) and I was wondering if there was a way to close two of the three forms (except one window) without closing the entire application (All 3 windows).

Thanx in advanced,
C++

Re: Keeping a Java App. Open but Closing One of the Windows
 
How are you making these forms? Are they modal frames, or just frames?

they're just in a separte class - they're just JFrames. Here's the code.

Thanx for your help,
C++

Re: Keeping a Java App. Open but Closing One of the Windows
 
I promise I will help, but I just took a 4 hour SAT, and don't feel like working right now!

Hi everyone,

Set the closing default constant of the frames to hide and set the visibility to false for the frames to be closed by buttons. See the java JFrame api and java JFrame tutorials for more details

Yours Sincerely
