Java Forum / General / June 2005A button close in JDialog
Hello I have a a JDialog (extends of JDialog class) object in that I have an aPanel (extends of JPanel class). In this aPanel, I have button. When I click this button, I want this dialog to close. Could you please tell me how to do that. I tried to use this function for the button: this.getParent().dispose() //obtain the parent (JDialog) then dispose it but this function does not work Thank you S.Hoa > I have a a JDialog (extends of JDialog class) object in that I have an > aPanel (extends of JPanel class).

The > Dialog is still visible. Well, duuh.. Try. theDialog.setVisible(false); or.. (invoked from the right place) this.setVisible(false); ..which translates to setVisible(false); SignatureAndrew Thompson http://www.PhySci.org/codes/ Web & IT Help http://www.PhySci.org/ Open-source software suite http://www.1point1C.org/ Science & Technology http://www.LensEscapes.com/ Images that escape the mundane Hello As the button is inside a panel, this panel is inside a theDialog, I do not know how to get the theDialog.setVisible(false). I also tried this.getParent().getParent().dispose() //this is the button but it doesn't work > Well, duuh..

I could tell you, but you can probably figure it out better by experimenting. // where is my mummy? Container c = (Container)this; while( c.getParent()!=null ) { c = c.getParent(); System.out.println( "Container: " + c ); } > I also tried > this.getParent().getParent().dispose() //this is the button > but it doesn't work Is it just lazy, perhaps? ;-) SignatureAndrew Thompson http://www.PhySci.org/codes/ Web & IT Help http://www.PhySci.org/ Open-source software suite http://www.1point1C.org/ Science & Technology http://www.LensEscapes.com/ Images that escape the mundane Thank you for your help I have to use this to get it works.

It is not about understanding *getParent()* method. It is about understanding who is the PARENT. :) > (chuckles) That was just to help you *find* it, but is > very fragile.

Or have some central repository where all your top-level windows register and de-register. /Thomas SignatureThe comp.lang.java.gui FAQ: ftp://ftp.cs.uu.nl/pub/NEWS.ANSWERS/computer-lang/java/gui/faq http://www.uni-giessen.de/faq/archiv/computer-lang.java.gui.faq/ >> while ( c.getParent() ! instanceof TargetDialogClass ) { >> c = c.getParent(); >> } > > SwingUtilities.getWindowAncestor() ..(checks subject line) Good point. I had completely lost that this was a *Swing* GUI matter and was thinking 'valid back to 1.1!' ( same old story ;) As an aside, do you know if that method has been available since the introduction of Swing? The javadocs are a bit vague on some of the '@since' tags..

Correct @since tags seem to be completely out of the scope of Sun's QA. /Thomas SignatureThe comp.lang.java.gui FAQ: ftp://ftp.cs.uu.nl/pub/NEWS.ANSWERS/computer-lang/java/gui/faq http://www.uni-giessen.de/faq/archiv/computer-lang.java.gui.faq/ >> (chuckles) That was just to help you *find* it, but is >> very fragile.
