Hi Bernd,
That was not too hard. There are at least two ways to find the information you
seek and accomplish your goal:
(1) Create the extension through the GUI that the Plugin Development
Environment (PDE) provides. First, you add an "org.eclipse.ui.viewActions"
extension. Second, you add an "action" to this extension. Third, you hover the
label of the field "class" that tells you "must implement IViewDelegate".
(2) [In case you don't like GUIs.] You search for the specification of the
extension point you want to use: Google Search for
"org.eclipse.ui.viewActions", and click on the first result:
http://help.eclipse.org/indigo/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Fguide%2Fworkbench_basicext_viewActions.htm.
Then you read "To provide the action behavior, the implementation class
specified in the plugin.xml must implement the
IViewActionDelegate<http://help.eclipse.org/indigo/topic/org.eclipse.platform.doc.isv/reference/api/org/eclipse/ui/IViewActionDelegate.html>
interface."
So instead of subclassing Action, you just need to implement
IViewActionDelegate.

Subject: [DPP-Devel] Problem with actions
Hello fellow developers
I have a problem adding and executing an action in the console-view of eclipse.
I put the following code at the end of the plugin.xml :
<extension point="org.eclipse.ui.viewActions">
<viewContribution
id="de.fu_berlin.inf.dpp.ui.ConsoleContribution"
targetID="org.eclipse.ui.console.ConsoleView">
<action
id="de.fu_berlin.inf.dpp.ui.ShareConsoleAction"
label="SarosConsoleSharing"
toolbarPath="Saros"
icon="icons/obj16/group.png"
tooltip="Share the Console"
class="de.fu_berlin.inf.dpp.ui.actions.TestAction">
</action>
</viewContribution>
</extension>
I created the class TestAction in the package: de.fu_berlin.inf.dpp.ui.actions
and filled it with the following content:
package de.fu_berlin.inf.dpp.ui.actions;
import org.eclipse.jface.action.Action;
public class TestAction extends Action {
@Override
public void run() {
System.out.println("Action tested");
}
}
In my understanding this should suffice. But when I'm pressing the button an
information window opens containing: "The chosen operation is not currently
available".
Can anybody please help me? Thanks in advance!
Sincerely
Bernd Bieber
