i am developing an application for which i have created different application windows. Now i'm in a confusion on how i can link one to another using a button, that is when i click a button, it has to navigate to the other application window.

Then I call:
SIMessage sm=new SIMessage(this, "Attention", SIMessage.TypeMessage.WARNING_MESSAGE,"You need to change ...");
callMethode2();
The problem is that it executes the call to Methode2 before showing any dialog while it is supposed to force the user to respond before continuing.
I see an empty window side by side with the window generated by callMethod2!, so what is wrong?

You should set the modality for Dialog.
A modal window is a graphical control element subordinate to an application's main window. It creates a mode that disables the main window but keeps it visible with the modal window as a child window in front of it. Users must interact with the modal window before they can return to the parent application.
So, Set the modal flag of the dialog when initializing it.
setModal(True)

I want to change the text on txtpnInscrito every time that atualizador() runs
But i don't know how to do this.
If i change the text directly in the button btnCasa it changes, but i want to make a refresher by time and utilize the same function to refresh when doing actions on buttons.
Thanks in advance.
And sorry for the horrible english.

You need to make txtpnInscrito field of the class so that it's accessible in all your methods within your class
Have a look at Understanding Class Members for more details

Toggle Java JPanels - each panel deifferent class

I'm a beginer in Java GUI, and i have an issue with trying to toggle between panel in other class.
My main Class "MyBoxGUI" has 2 Panels, "Login" and "UserMenu"
The default is "Login" panel, when pressing "OK" the window moved to "UserMenu" Panel.
So far so good while in the same class.
The issue is, when i set a new panel in new class and setvisibe that panel, i can't go back to "UserMenu" panel - (The actionlistener is working fine).
Can someone help me please?
