JPopupMenu display under Canvas

Question

I have a Canvas, some text fields and a context menu.

When I start the application and right click on the canvas a popup menu shows. But when I write something inside the text field than I right click on the canvas, the popup will shows behind the canvas.

Any idea how to fix that ?

put up some code, ideally an SSCE. Usually, just by writing an SSCE you will find your issue. – Motteo

Answer 1

JPopupMenu.setDefaultLightWeightPopupEnabled( false );

solved the issue.

Boor

This call affects all popup menus that will be created in future. Usually it is enough to modify lightWeightPopupEnabled property of the particular JPopup instance by calling popup.setLightWeightPopupEnabled(false). – Calibrate

Answer 2

1) Canvas is AWT Component, and is Heavyweight type of Components

2) JPopupMenu is Swing JComponent and is Lightweight type of JComponents

3) possible to solve that by using Swing JPanel rather than AWT Canvas

4) your issue is about Mixing Heavyweight and Lightweight Components or rest is here

I need a Heavyweight component to draw into it with opengl. – Cernuous

agreed correct way for OpenGL, your choice is more simpler than use JPopup use Window or un_decorated Dialog, there you can put Swing JButtons, for laying use GridLayout – Stochmal
