Pulldown actions in the View toolbar problem [message #435205]

Hello, guys!

I'm a newbie in eclipse so it maybe a little difficult for me to
understand some basic concepts. I see that declarative way of creation new
actions is very simple and nice (using org.eclipse.ui.actionSets and
org.eclipse.ui.viewActions extention points).

The only problem I met here is to create Pulldown action in the view local
toolbar (not a pulldown menu)...

Please, help me with this thing (the declarative solution if possible).
Generally, I think this feature is possible (for example - "Console View"
in the Eclipse IDE has such actions: "Display Selected Console" and "Open
Console")

Thanks:)

Hi Alexei,

Actually pretty simple. I did a simple snippet for you that should work. You
need to implement an action that implements IMenuCreator which provides the
getMenu()-method. This method provides the menu and fills it with the
content you want to show. Typically you would futhermore add ActionItems to
that. You can find a sample for that in the code of the console view (see
below).

Finally you need to initiate this by calling setMenuCreator of the class
Action in your constructor.

public class MyView extends Action implements IMenuCreator {

private Menu fMenu;

public MyView ()
{
setId("myId");
setToolTipText("myToolTip");
setImageDescriptor(ImageUtils.getImageDescriptor(ImageUtils. COLLAPSE_ALL));

// this is the first magic portion for it
setMenuCreator(this);
}

/* this is the second magic portion for it */
public Menu getMenu(Control parent) {
if (fMenu != null) {
fMenu.dispose();
}
fMenu= new Menu(parent);
MenuItem menuItem = new MenuItem (fMenu, SWT.PUSH);
menuItem.setText ("hello 1");

return fMenu;
}

// other methods like run and to empty ones that are needed for
interface
}

Here's how you can view the source code of the console-view. Open the
plugin-view. Here you will find a plugin named org.eclipse.ui.console.
Right-click, import As Source Project. Now go to Navigator or Package
Explorer and open this new project. You will find the
org.eclipse.ui.internal.console.OpenConsoleAction under source. Here you'll
see the same approach only that getMenu uses addActionToMenu() to add
actions to the Menu.

Sorry, I forgot to add the call in the view to integrate into the toolbar:

IToolBarManager toolbar=
getViewSite().getActionBars().getToolBarManager();
MyViewAction menuAction = new MyViewAction ();
toolbar.add(menuAction);

and of course the class name for the Action should be called MyViewAction
not MyView

Hello, Stefan!

Thank you very much for your answer:) It is really useful for me... And
what about declarative way of the action definition (I mean plugin.xml).
Is this impossible to make the pulldown action this way?

It seems that xml-scripting eclipse abilities are restricted to make some
simple actions (actionSets) which are not accessible and reusable from
other application parts...

Am I wright?

Thank you ones more for your examples:)

You are welcome :-)

I don't think that there is a way to do that because it involves much more
that pressing the button. How would you fill the entries in a declarative
way? What would the entries do (declarative-wise)? The only application I
would see is that those entries again are actions....

Stefan,

Menu entries are actions. It's OK for my needs. But I spent much time
searching the web and docs for the XML instructions how to do this. It
seems the best way to make actions (even not pulldown) is to define them
in the source code.

Also I see that there is the xml instuction to make the pulldown action on
the application top-level (whole workbench) but there are no similar
instruction for the view or editor part...
