I know that I can declare actions in plugin.xml that specify style="pulldown" in order to make a pulldown style toolbar button, but I want to be able to do it programatically, using the IToolBarManager and IContributionItem interfaces.
I've looked through the interfaces, and the implementations of various things in eclipse, but I can't see how I'd do it. Ideally I want to add such a toolbar item from an IEditorActionBarContributor implementation.
Anyone got any ideas?
In answer to my own question, you need to create an Action object, and then call setMenuCreator on the action. Then when you add the action to the toolbar you'll get a drop down menu.

I am a beginner in intellij plugin development. I need to add a project type by my plugin in New Project Wizard. I could manage that part with <extention> tags in plugin.xml. Now I need to add a CustomWizardStep when I click the next button after selecting the project type. What is the first method called when that button is clicked in which class? Can anyone please explain?
I think you are looking for com.intellij.ui.wizard.WizardStep#onNext method.
You can extend the com.intellij.ui.wizard.WizardStep class to use in your own wizard.
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 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)
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
In our code base there are a few very long methods (several pages worth of code). When reading the code, it would sometimes be good to be able to see the name of the method the current line belongs to, without paging up to the beginning of the method. Is this possible in Intellij IDEA? I am using Intellij IDEA 7.0.3.
You can use View | Context Info (Alt+Q, Ctrl+Shift+Q on Macs). It will display a pop-up on the top of the editor with the current context information (class/method signature).
IntelliJ 2018
This is shown by default at the bottom.
Unfortunately, the method is shown only by name (not including the parameters). If a method is overloaded you won't know for sure where you are.
If you want to move it from bottom to top, go to File > Settings... > Editor > General > Breadcrumbs > check Top:
In the structure panel select the "Autoscroll from source" option.
This way when you place the cursor inside any method the structure panel will show which method you're in.
Intellij now has support for breadcrumbs. Go to settings > appearance and tick "Show breadcrumbs". In this way you can view class/method name without Alt+Q.
For some reason (Alt-Q) wasn't consistent in Android Studio for me. I find (Ctrl-F12) to be pretty satisfactory for this purpose (Navigate|File Structure) though it can be a little laggy in larger files. And by pressing the hotkey again it will populate the list with all the inherited methods as well.
