12.9. Creating Actions
Problem
You want to create menu items and toolbar buttons and connect Java code to them.
Solution
Create a new action, add menu items and toolbar buttons, and implement what you want to have happen in Java.
Discussion
Building upon the example developed in the previous two recipes,
we’ll now add menu items and a toolbar button to the
plug-in. Right-click Action
Set
1
in the Extensions box of the plug-in manifest
editor and select New→ Action. In the Properties view, set
the label
property to Action
1
, the toolTip
property to
This action is
functional
., and
the id
property to Action1
.
Next, set the menubarPath
property to
Menu1/Group1
and the
toolbarPath
property to Group1
.
That connects the action to the menu item and toolbar button.
To connect the action to code, select the action, Action 1
, in the Extensions box, and click the ellipsis (...)
button that appears when you select the class
property in the Properties view. This opens the Java Attribute Editor
shown in Figure 12-21.
Figure 12-21. Creating an action class
Select the “Generate a new Java
class” radio button, enter
org.cookbook.ch12.MenuPlugInFromScratch
in the
“Package name” box (or click the
Browse button and select that package), and name the class
Action1
, as shown in the figure. Then click
Finish. This creates the new action and adds its Java support file,
Action1.java
, to the project.
