| 14. 26. 5. 显示JPopupMenu的AWT组件 |
|
|
If you need to enable the display of a Panel (an AWT component), you can configure it at the individual
JPopupMenu level or for your entire applet or application.
At the individual pop-up level, just set the lightWeightPopupEnabled property to false. |
The setInheritsPopupMenu() method accepts a boolean argument.
When true, and no component pop-up menu has been directly set for the component, the parent container will be explored for a pop-up. |
At the system level, this is done as follows: |
|
// From now on, all JPopupMenus will be heavyweight
JPopupMenu.setDefaultLightWeightPopupEnabled(false);
|
|
