eclipse menu contribution - eclipse-plugin

I want to add a menu to the eclipse menubar in a RCP application and that menu will be shown active based on some condition(e.g return value of some method) in Java code .Please let me know how can I do it.

Here you find some short examples. Maybe that is enough to give you an idea.

A menu can not be enabled/disabled directly based on an expression - that is only possible for the menu items themselves.
To enable/disable a menu item, have a look at Command Core Expressions in the Eclipse Wiki...

Customize existing menu/toolbar Item

I am building a netbeans platform application. This application is project based. I need to customize existing menu/toolbar items.
For instance, when a java project is selected, the "New File" button on the toolbar brings a standard wizard. But when a custom project (my project type) is selected, I would like that same button to bring my own dialog/wizard.
How do I achieve this?
I have been struggling with this for quite some time, any pointer would be greatly appreciated.

Pop-up menu is not fully visible in IntelliJ IDEA

I am just evaluating IntelliJ IDEA. Installed it with default procedures.
I created a simple Spring project and when I right click on the project, not able to see the the bottom part of the pop up menu. The issue is because of my laptop screen's height is less and could not fit the entire set of pop-up menu items.
In eclipse there is a drop down arrow, so that I can scroll to the menu items, which do not fit in the screen. How can I get the similar eclipse functionality in IntelliJ?
Well, you are only missing one useful feature (Genereate Java code from wsdl). I would ignore it unless you need to generate such code.
If you want to run this generation you can do this with Ctrl + Shift + A (and start typing feature name)
//btw, it is better to make code generation in maven anyway

How to add a button to the main toolbar in Eclipse programmatically

I've a question. I cannot find the way, how to add buttons to main toolbar programmatically. My problem is, that I've the task to dynamically (based on XML configuration file) build menus and toolbar. I found how to add a menu item programmatically, but not toolbar button.
Tutorials mostly show how to create buttons and menus using plugin descriptor (plugin.xml), but not how to do it programatically. It seems, that it is out of bounds of Eclipse plugin philosophy.
I've just found this:
There might be layout problems with this approach. I also don't
believe the framework will try and re-create your dynamic item except
at random toolbarmanager updates. With Menus they can be updated on an
SWT.Show event, which is why CompoundContributionItem only applies to
Menus.
What shall I do? Can I say Sorry, there is no way to build toolbar dynamically. I can do it just for menus? Collegue says, that it must be possible, but he does neither know how.
The only way to be able to create main toolbar entries programmatically is in an RCP app, where you supply the ActionBarAdvisor for the workbench window. This isn't dynamic, however, just called on window creation.
Another way to do it would be to use org.eclipse.ui.menus and contribute org.eclipse.ui.menus.ExtensionContributionFactory. It also works only on workbench window creation (not really dynamic), but you could read your own XML and provide IContributionItems for the main menu or toolbar.
How dynamic are you trying to be? Most solutions work well on startup/window creation.

Whenever you try to do something programmatically in Eclipse that is normally done through plugin definitions you are walking on thin ice. I've tried it on a few occasions and it rarely ended up being easy or good.
Instead, think of what it is that you only know at runtime and need to be able to change on the fly. Is it the name or icon of the button? That can be changed at runtime.
Take a look at runtime commands, they can be confusing to define properly, but with them you can for example create buttons that are only visible if a condition is active. That condition could be set at runtime.

How can I add an AppleScript menu to my menubar?

How can I add such a menu to the menu bar in my Cocoa application?
Various applications, for example Coda, have this. Is there an easy way to do this or must I implement this myself?
You must implement this yourself.
The ApplScript Editor has a preverence page where you can activate "show apple script menu in menu bar" (or something similar worded)

Editor context Menu - Eclipse-RCP

I have an Eclipse RCP application. I have created an Editor. There are few context menu (default), when I right click on the Editor. I have not created these menus.
Please let me know, How to remove the context menu of the Editor?
It needs different approach by which editor you extends.
Let me know What you extends, than I can answer more efficient one.
In general way:
IWorkbenchParSite#registerContextMenu(...) will be used, So find where calls that, override it. It is not recommend. Because by doing this, Menu Extensions which is contributed for your editor will not work anymore.
If you mean the system menu that appears on editor tabs and view tabs, that menu is provided by the presentation (2.1, Classic, Default, etc). There is no tweak to simply modify it.
The 2 ways to remove it would be:
write your own presentation, using
the
org.eclipse.ui.presentations.StackPresentation
API and matching extension point.
Writing a presentation is a involved
undertaking.
Change the internal classes in the
org.eclipse.ui.workbench plugin
and patch that plugin in your RCP
app.
If you use Text or StyleText you will get the system default menu (cut,copy,paste, maybe something about encoding or input). If you are not going to supply your own menu, simply create an empty SWT Menu and set it:
Menu emptyMenu = new Menu(text);
text.setMenu(emptyMenu);
Eclipse also has a text editing framework, if you need more than a basic text box you should check it out. http://wiki.eclipse.org/The_Official_Eclipse_FAQs#Text_Editors
