(I'm something of an Eclipse newbie, so apologise for any dumbness on my part...)
I have a number of editors (derived from IEditorPart) in my RCP app, and a requirement has arisen that one particular editor needs to be also available in a modal dialog box (along with some extra controls) opened by one of the other editor classes. The editor to be embedded consists of the main viewer control, toolbar, and a couple of dozen helper classes (label providers, comparators, etc).
The options before me appear to be:
Find a way to put an editor area, IWorkbenchWindow-style, into a (JFace or SWT) Dialog.
Not had much luck searching for how to do this
Create a new WorkBenchWindow with a Perspective that just the editor area visible, and no views. Make this modal.
On trying this, the new window seemed to inherit things (menus etc) from its parent window.
Refactor the editor in question so all of it now resides on a single control, then embed this control in both the editor and the dialog.
Potentially time-consuming, given the number of places the helper classes refer back to the main editor object.
If it turns out that this is a truly perverse and anti-idiomatic thing to want to do, in Eclipse terms, can you suggest a wiser course of action?
Thanks
EditorParts are meant to be inside workbenchwindows. There is a lot of code that depends on this behaviour. So I would suggest not to do (1). If the result is acceptable (a workbench window, which is modal), the easier way is to hang on to (2).

For a custom language I created a CompletionContributor. Everything works fine. But I'm limited to the information I can display (only in the list or the bottom "advertisement" and only 1 line).
When trying to auto-complete on a java class name it will display more information on the selected line in a small side window. I would like to exploit that mechanism but I really don't know how it is done.
When looking at the options provided, I can use a custom LookupElementRenderer but there is no method in LookupElementPresentation related to the right window.
Any idea how it is done?
Are you referring to documentation popup which may be displayed if the corresponding setting (Setting->Editor->General->Code completion->Show the documentation popup in) is turned on?
If you want the feature to work for your language you have to use lang.documentationProvider extension point.
I learned to program 30 years ago with Emacs. I'm starting to learn moderns IDEs such as "IntelliJ IDEA", "PyCharm", and "VS Code".
It's hard to adjust to how visually "busy" they are, with constant pop-up menus appearing every character I type.
Of course I want to be able to get suggestions for completion or parameter hints or other popups when necessary. I just don't want them to appear by default.
Some people are asking why popups are annoying. The main problem is that popups cover code above or below where I'm typing.
Emacs has completion. But it doesn't need a popup. For instance, dynamic completion works just fine 90% of the time, even though it's not smart enough to parse syntax or look up function and method definitions.
So I'd like to know if there are settings in JetBrains or VS Code IDE's that would help.
I'm aware of two kinds of popups.
(1) An offer to complete my typing, which appears below.
(2) Annotation of argument names and definitions, which appears above.
There may be other popups as well.
I'm aware that a popup can be dismissed with ESC. But often they just come back the moment you type another character.
What would be great is if the popup would not appear by default, but I could cause it to appear with a single keystroke. Or I could dismiss it and it would stay dismissed.
For PyCharm You can also try writing in "Disctraction Free Mode"
View -> Enter Distraction Free Mode
Which should give you a little screen of calm which will feel a lot more like emacs to you.
It's possible to adjust the behaviour via "Settings".
In IntelliJ IDEA, goto Menu File --> Settings ... , then navigate to Editor --> General --> Code Completion , or type something in the search field (upper left).
Perhaps you find more settings when you browse through Settings dialog.
To be honest, I didn't make a lot of tests with these settings, because I find the helper popups very useful.
Another option to get rid of some "noise" is to adjust settings for displaying parameter names in the code editor.
I switched this off completely.
Go to Settings --> Editor --> General --> Appearance
The new IDEs are really busy looking for libraries, checking/auto closing balanced parentheses, indenting, surrounding methods/functions/procedures/classes as you type. Sometimes I feel the same, but these IDEs are not plain text editors anymore. Every key stroke triggers something which can be time consuming. When the project gets larger and when it has lots of libraries, it can get even slower. Some IDEs have options to turn some of these options off. Every feature turned off will have some positive effect on responsiveness to some degree
But I think, instead of turning these features off, the best way to have these features on a responsive modern IDE is to use a computer with a fast cpu, an ssd drive and sufficient memory.
In Eclipse I could hit Ctrl+O and get a popup which I could use to get an overview of everything in the current class, pick an entry, and jump to it.
In idea, there is Alt+7, but I have a few issues with it. First, the keyboard doesn't seem to put its focus there. I have to take my hand off the keyboard and use the mouse to place the focus on the Structure dock.
I also don't like how it's taking up real estate. I don't want to change how things are laid out if I want to see the structure. I would like a more non-invasive popup, and handier and snappier.
Is there another feature that gives me quick access in the form of a popup preferably, like Ctrl+O provides in Eclipse?
Another nice feature would be to be able to use the J and K keys to move up and down the selection, instead of having to use the cursor keys. I'm using IdeaVim, so the normal workflow when editing files, is that both hands stay in a touch-type position. It would be nice if I can use the various navigation features also using vim keys...
Perhaps there is a way to enable this, that I haven't discovered yet?
IntelliJ equivalent of Eclipse's CTRL+O is CTRL+F12 (⌘+F12 on Mac), which will give you more or less the same pop-up as in Eclipse. But I'm not sure if it can be navigated using j and k keys.
More details can be found in the IntelliJ help.
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.
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
