MouseUtils.PopupMouseAdapter (UI Utilities API)

java.lang.Object
- java.awt.event.MouseAdapter
- - org.openide.awt.MouseUtils.PopupMouseAdapter

Enclosing class:

MouseUtils
```
public abstract static class MouseUtils.PopupMouseAdapter
extends java.awt.event.MouseAdapter
```
The PopupMouseAdapter provides safe way to implement popup menu invocation mechanism. It should be used instead of invoking the popup in mouseClicked because the mouseClicked does not work as "often" as it should (i.e. sometimes it is not called). PopupMouseAdapter delegates to isPopupTrigger to get correct popup menu invocation gesture. Clients are supposed to extend this class and implement showPopup method by adding code that shows popup menu properly.
Please note that older implementation which used treshold is now deprecated, please use default constructor.
