How to know the name of the window

[Nouf Nassri]

Hi everyone

I have 3 frames Fe1, Fe2 and Fe3 The first frame contains two buttons Button 1 << view Fe2 "and button 2 <<viewr Fe2>>
I like when I click a button1 it should check if the frame f3 is active when f3 is active then it must close f3 and display frame f2 and the reverse for button 2

Thank you for the help.

Hi,
have you created any code and faced with problems? if so let us know what's the problem and we'll help you...
By the way with the informations you gave, by looking at (J)Frame's documentations, i would simply suggest you the method

  isVisible()  

or if you mean something more than just visibility, the methods

  isValid()  

or

  isActive()  

So you can check the status of any frame by these methods and do what you want by means of another methods in JFrame:

  setVisible(boolean b)  

or

  validate()  

bes of luck

Frame 1

Action Button1

  

if(f3.isVisible()){
f2.setVisible(true));
f3.setVisible(false));
}else{

f2.setVisible(true));
}

 

Action Button2

  

if(f2.isVisible()){
f3.setVisible(true));
f2.setVisible(false));
}else{

f3.setVisible(true));
}

You can simplify and clarify that:

if(f3.isVisible()){  
   f3.setVisible(false));  
} 
f2.setVisible(true));
...
if(f2.isVisible()){  
   f2.setVisible(false));  
}  
f3.setVisible(true));

Then simplify further:

switchFrames(f3, f2);
...
switchFrames(f2, f3);
...
void switchFrames(JFrame oldFrame, JFrame newFrame) {
   if (oldFrame.isVisible() {
      oldFrame.setVisible(false);
   }
   newFrame.setVisible(true);
}

In fact, you don't even need the 'if' statement - it's OK to call setVisible(true/false) on the frame whether it's visible or not:

switchFrames(f3, f2);
...
switchFrames(f2, f3);
...
void switchFrames(JFrame oldFrame, JFrame newFrame) {
   oldFrame.setVisible(false);
   newFrame.setVisible(true);
}
