Giving JDialog the correc

Show all headers | View raw

  To: comp.lang.java.gui
Often I find an error or want to give the user some information I am 
doing so in a class that is an extension of JPanel. However, this JPanel 
may have another JPanel as it's parent, or some other Container class. 
So if I have to show a modal JDialog or JOptionPane I don't know what to 
provide as the parent.

Providing null to a JDialog means that if I click on another window and 
then back onto the original, the dialog dis-appears behind the main window.

Does anyone have a design solution to this? I sort of thought that I 
might have a class that tracks the active window, but then all windows 
would have to register and de-register with this class . . . doesn't 
seem very convenient.

Any help appreciated.

Lionel.
