I've searched on the internet about removing some of the right click context menu items such as Copy, Run as...,Show in and others and I didn't saw a certain answer about this.
Is it possible to remove these contextual menus without actually removing the plugins that add these contributions to it , a kind of filter for the contextual menu ?

I'm trying to create a plugin for eclipse and for the one of the requirements is to add an entry to the context menu for all text editors so that on right click I get an option corresponding to the action I want to perform. I've tried to find relevant resources for it but most of the use cases are focused on adding a context menu to a view etc and not to the context menu for the eclipse editor. So far, I tried to implement this using the eclipse context in the activator but as is perhaps obvious, the workspace is not created when the activator's start method executes. Any help would be appreciated!
I am developing an Eclipse RCP application, and would like to remove some of the items displayed in the "Show In" context menu. The items are placed in this menu by various plug-ins, and I would prefer to not have them there.
Adding a new entry to this menu is well documented: https://wiki.eclipse.org/FAQ_How_do_I_make_my_view_appear_in_the_Show_In_menu%3F
However, removing an existing entry seems problematic, since Views are listed in the "Show In" menu by virtue of them implementing the IShowInTarget interface. The resulting menu items do not have unique IDs that could be used to disable them via an Activity.
It seems to me like the only way to avoid listing a View defined by an existing plug-in in the "Show In" menu is to extend the plug-in class implementing this View.
The source code for the 'Show In' menu is org.eclipse.ui.internal.ShowInMenu.
This gets contributions from a number of places but I don't see anything that could be used to filter them.
'Extending the plug-in class implementing the view' is not really possible.
I have a org.eclipse.swt.browser.Browser instance created in a composite. I would like to know when some content is pasted in the browser using the (platform specific) right click context menu and selecting the paste option.
In the menuDetected() of MenuDetectListener, I get a notification when the context menu is detected in the browser.
How can I know if the Paste option is selected from the context menu?

No you can't access the selected context menu item. There is no direct provision for that. At least not in eclipse 3.7. Although, you could try different combinations of events for determining the menu item. For example, in windows the internet explorer populates the status bar with 'inserts the clipboard...' when your mouse pointer hovers over the Paste menu item, you can capture this using StatusTextListener event.
Note: The hack is not an elegant solution, even if you get it working, there is still some possibility that it may break with new or older releases of SWT or in fact its behavior may vary with operating systems !!
My question can be split into three:
Is it possible to hide/remove arbitrary context menu items in Eclipse (3.6) by ...
standard UI?
some existing plug-in?
custom plug-in?
I failed to find ways to do this by methods 1 and 2. If the only option is creating custom plug-in, could anyone push me towards the right direction where to start (I have some experience in Java, but not in Eclipse plug-ins).
You can hide menus or menu entries through the standard GUI: see help
To hide a menu item or toolbar button:
Switch to the perspective that you want to configure.
Select Window > Customize Perspective....
Open the Menu Visibility or Tool Bar Visibility tab.
Find the item you want to hide.
Uncheck the check box next to the item. Uncheck a menu to hide all its children.
Click OK to cause the changes to take effect.
But that will hide this entry from all the menus (contextual or not) in which it is present.
So it may not be as fine-grained as you want through the GUI.
You can also try it through a plugin (see also Menu contribution)
The first steps are pretty standard for using extensions in Eclipse.
Open the plugin.xml file and add the org.eclipse.ui.activities extension.
Then create an activity node and give it a unique ID.
Then create an activityPatternBinding node and use the unique ID for the activity to find the pattern node to the activity node.
The activityPatternBinding node requires that you supply a regular expression for the ID string of the UI element that you wish to hide.
The problem is that there appears to be at least 3 ways that menu items and toolbar buttons are added to the UI.
The first way is through the newer Command/Menu Extensions.
The second way is through the older ActionSets Extension.
Then there are other UI elements that appear to be hard coded into the Workbench and do not have ID strings and cannot be hidden using the Activities Extension. Luckily there are few of this third type of UI element.
Considering you are talking about the latest Eclipse, I will copy only the first way:
1/ Use the Plug-In Spy
The first way is to use the Plug-In Spy.
Press alt-shift-F2 and click on a menu item or toolbar button that you want to be hidden.
If there is an ID string under the heading "active action definition identifier" then you are in luck.
This item has been added using the Command Extension and you can use this ID as the pattern argument for the Activities Extension.
But not all items that have been added using the Command Extension present their ID string to the plug-in spy.
As a side note, the ID strings are period separated.
For instance the ID for a button might be "org.eclipse.ui.navigate.backwardHistory".
Regular expressions use the period to stand for any character. Luckily the period used as a wild card matches with actual period characters so you don't need to escape them if you don't want to. I find it makes it a bit easier to read if they are not escaped and it is highly unlikely it will cause any ambiguous matches.
I am pretty new to eclipse. I notice that depending on the Perspective I am in, the new submenu lists different items in it. Is there a way to pick the items it lists (modifying the perspective) just using the eclipse interface? or am I needing to do a plugin of some sort to enable this.
Go to Window >> Customize Perspective
You should be on the Shortcuts tab and should see a dropdown called Submenus:
Make sure you have the "New" submenu selected and from there you can add New shortcuts.
