view action delegate with sub menu ... [message #332277]

Thu, 16 October 2008 08:22

Eclipse User

Hi all,

I need to implement a view action that will display, as a submenu, a list of
actions when selected ... the action comes from extension point (view action
delegate)

VIEW CONTEXT MENU
________________
- Action 1
- Action 2
- List Action
- sub action a
- sub action b
- sub action c
- sub action d
- Action 3

I'll try to describe what I need to do ...

I have a list of names that I know at runtime ...
When I select an item in my view I would like to see in the context menu my
"List Action" action with a submenu that will list the actions (each one
named with the name I read when the application when it starts ...)

I have found a way to do this via a normal action (jface.action) where I can
override the setMenuCreator (with IMenuCreator) ...
But what shall I do here ...

This action is contributed to my view from a fragment so I cannot directly
add the action to the context menu and I cannot create in the

Any suggestion, or a better approach will be appreciated.

Thanks
Kar

<fragment>
<extension
point="org.eclipse.ui.popupMenus">
<viewerContribution
id="org.eclipse.ui.articles.action.contribution.popup.navigator "
targetID="com.xxx..views.DBView">
<action
class=" org.eclipse.ui.articles.action.contribution.ViewAction1Deleg ate "
icon="icons/command.gif"
menubarPath="additions"
id=" org.eclipse.ui.articles.action.contribution.navigator.action 1 "
label="View Action 1">
</action>
<menu
id=" org.eclipse.ui.articles.action.contribution.navigator.subMen u "
label="View Sub Menu"
path="additions">
<separator
name="group1">
</separator>
</menu>
....
....

Yes, don't use actions.

You can use org.eclipse.ui.menus to create a view submenu that contains
a dynamic contribution ... implement CompoundContributionItem and you
can return your dynamic list (I'd still suggest commands and
CommandContributionItems, but you can return ActionContributionItems if
you are so inclined).

Thanks Paul . it worked .

One more question if I can .

The example works fine when I add the dynamic actions to the context menu
but I would love to create a sub menu (SUB ACTION) that will be populated
with the dynamic actions.

I have tried:

a) Adding in the plugin C (the one that will display the dynamic actions) a
popup menu extension point that will just create a new menu separator .
I have tried to set the menu contribution uri to
"my.project.menu3/subseparator" with no luck (I can only see the the action2
in the sub menu) - the example works fine if I use additions in the uri.

b) Or shall I put the popup menus extension point in the plugin B - the one
where is present the db view .

c) I have even tried to create a sub menu ( in the bit of code that will
fill the context menu . ) but still I cannot add the dynamic action plus the
context menu start acting weirdly (separator appears and disappear each time
the context menu is displayed)

MenuManager viewMenu = new MenuManager("Local View", "locals");
viewMenu.add(new Separator("popuplactions"));
viewMenu.add (actionExecEomdbAction);
manager.add(viewMenu);

What am I doing wrong?
Thanks Kar

Paul sorry ... one more question ...

in the previous post I told you I was using the View Action Delegate to
perform my action ...
now, using the CommandContributionItem and the command handler how can I
know (or at least from where) the selected item in the view ... can I do
something similar selectionChanged ...

thanks

This needs to be in your menu contribution, since org.eclipse.ui.menus
can't see popupMenus

With a subclass of AbstractHandler the execution event contains the
current selection and the active part. You can use the helper methods
on HandlerUtil to get them. For popup menus, check out active menu
selection and then selection.

Hi Paul . solved problem about command parameters and selected item .
I still need to create the sub menu with the dynamic actions on the view
context menu .

I have tried adding the following bit to the main plugin (the one with the
view):

<extension
point="org.eclipse.ui.menus">
<menuContribution
locationURI="popup:com.utils.views.DBView?after=additions">
<menu
id="myid"
label="MyLocalAct">
<separator
name="Utils.separator1"
visible="true">
</separator>
</menu>
</menuContribution>
</extension>

And in the extending plugin use:

<extension
point="org.eclipse.ui.menus">
<menuContribution
locationURI="popup:com.utils.views.DBView?after=myid/Utils.separator1 ">

<dynamic
class="my.project.MyCompoundContributionItem"
id="my.project.myCompoundContributionItem">
</dynamic>

....

This did not worked . (if I use just after=myid I can see the list of
commands listed in the main level of the context menu).

-----

I did tried to put all the bit of code in the extending plugin .

<extension
point="org.eclipse.ui.menus">
<menuContribution
locationURI="popup:com.utils.views.DBView?after=addition">
<menu
id="idtest"
label="TESTTEST">
<dynamic
class="my.project.MyCompoundContributionItem"
id="my.project.myCompoundContributionItem">
</dynamic>
</menu>

</menuContribution>
</extension>

No action is displayed at all.

Could u please help me
Thanks in advance
Kar
