How to avoid this problem...

[pbaudru]

Hi All,

I have this JFrame. I'm using Eclipse.


When I select something on the second JComboBox the 'spécification' JComboBox is refreshed.....but something weird happens at the same time.....the JButton NEXT (>) turns 'invisible'......


Then when I move the mouse or click in some object on the JFrame this 'NEXT' JButton (>) becames very big and we only can see it on the JFrame.....


How can I avoid this problem please ?

Best regards, Pierre.

Hard to tell without seeing your code. Did you accidentally mix AWT and Swing?

Hello,

Thanks for your message !

Yes I have both AWT and Swing.....I didn't know that would be a problem to mix these two.....
I have this on the code:
import javax.swing.*
import java.awt.*

So, in this case....with one should I have to delete ?

Regards. Pierre.

You cannot really delete any of them as you still need events from AWT. I'm only guessing here, so post your code or an Short, Self Contained, Compilable and Executable, Example Program

Hi,

My code is here bellow......you will see that I'm really new on JAVA development....I started with this on 4 january 2010....I know that I still have to learn a lot of things, before I was a CoolGen/Cobol developer....anyway thanks a lot for your help....if you have any suggestions to change my code please let me know, I will appreciate that !

Pierre.

Ouch! Stop right there and go back to the basic tutorials.
Code Conventions for the Java Programming Language
Sun's basic Java tutorial
Trail: Creating a GUI With JFC/Swing (The Java™ Tutorials)

Your code violates the code conventions.
You produce procedural code instead of classes and objects.
You don't use models (see the Swing tutorial)
You use eclipse without knowing the basics. Stay with an editor and the command line until you can create GUIs, mastered classpaths and packaging.
