Adding a conditional popup menu to a Jtable using Matisse in Netbeans?

[Pete Dawson]

Hi,
I'm trying to add a popup menu to a Jtable such that the menu only shows when a row is selected in the Jtable. Can anyone help me with how to do this,
I'm using the Matisse GUI builder in Netbeans 6.7.1
I can add a popup menu OK but it is possible to pull up the menu even when no table row is selected, this is what I am trying to avoid.

Thanks
Pete

Pete,
Welcome to the Ranch.

How are you showing the popup? Have you used the JCOmponent#setComponentPopupMenu()? If yes, you will need to use mouse listeners and use the JPopupMenu#show() instead, which will be triggered only if any table row(s) is/are selected.

Thanks for the reply,

Yes the automatically generated code contains

jTable1.setComponentPopupMenu(jPopupMenu1);

So that means I need to back up a step and add the menu programmatically myself? GUI builders are a bit tricky when you can only do part of the job with them!

Which is why people who want to learn Swing don't use them.

Pete,
To answer your question, yes. You will have to use the mouse listener approach.

I am with Rob here. IDEs which auto generate the code never give you the level of control which hand coding does (as you have found out yourself). Also, Netbeans generated code will not (always) work on other IDEs like say Eclipse.
