Hi,
You need to use ActionContributionItem class. I have a sample action class
below.
package com.microstrategy.web.sdk.seditor.actions;
import java.util.Iterator;
import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.Control;
import org.eclipse.swt.widgets.Menu;
import org.eclipse.swt.widgets.MenuItem;
import org.eclipse.jface.action.Action;
import org.eclipse.jface.action.ActionContributionItem;
import org.eclipse.jface.action.IAction;
import org.eclipse.jface.action.IMenuCreator;
public class DropDownAction extends Action implements IMenuCreator {
private Menu fMenu;
public DropDownAction() {
setText("My Actions");
setMenuCreator(this);
}
public void dispose() {
if (fMenu != null) {
fMenu.dispose();
fMenu= null;
}
}
public Menu getMenu(Menu parent) {
return null;
}
public Menu getMenu(Control parent) {
if (fMenu != null)
fMenu.dispose();
fMenu= new Menu(parent);
int i= 0;
Action filterAction = new Action("Filter") {
public void run() {}
};
Action gen = new Action("gen",IAction.AS_DROP_DOWN_MENU){
public void run(){}
};
addActionToMenu(fMenu, filterAction);
new MenuItem(fMenu, SWT.SEPARATOR);
addActionToMenu(fMenu, gen);
return fMenu;
}
protected void addActionToMenu(Menu parent, Action action) {
ActionContributionItem item= new
ActionContributionItem(action);
item.fill(parent, -1);
}
public void run() {
}
/**
* Get's rid of the menu, because the menu hangs on to
* the searches, etc.
*/
void clear() {
dispose();
}
}
In the View, add the following code to add the above action.
DropDownAction dn = new DropDownAction();
manager.add(dn);
I hope this will solve your problem.
