I have two laptops and on one of them in Eclipse I was able to add a type hierarchy that shows class members, etc. directly under the opened files (or whatever you call the tabs that are right about the red box in my image). I have no idea how to do this though, anyone have any suggestions?
Also, on a related note, when I do just open the type hierarchy it always requires that I open it given the context of the current opened .java file. On my other laptop it's sort of dynamic and allows me to explore the type hierarchy of whatever file I'm viewing. I want it all to work like how it is in Microsoft Visual Studio.
I think you mean the breadcrumb - Navigate > Show in Breadcrumb

RStudio uses Chrome Devtools for debugging support in its Viewer pane. (It is labelled as "RStudio Devtools", but I'm not sure to what extent it is customized besides that). You can open its window using Right-click "Inspect Element".
When developing a display that uses Javascript, the source pane in Devtools is very useful for setting breakpoints, single stepping, etc.
One thing that is fairly inconvenient is finding the line where I want to set a breakpoint. Once I have the source file open searching it is easy, but getting to the right source file is hard. Typically after I go to the source pane, I see something like this:
I know the name of the file I want to debug, but it's buried several levels below index.html in the list of files on the left. Is there a way to quickly search this hierarchy of files for a filename, so that I don't need to open all the levels down to the file I want? For example, I might want to debug htmlwidgets.js:
You'll note in the "sources" pane that, if you have no open files, you'll see a message in the middle that indicates you can type Command + P (or Ctrl + P on Windows/Linux) to open a file. When clicked, this will open a text box that will fuzzy search across the names of all source files. Type the filename there and it should be in the first results. You can navigate to it with the keyboard and select it with <Enter>/<return>, or simply clicked with the mouse.
In an Eclipse based application (RCP), when double clicking on a file that appears in the project explorer, for the first file this will work – the associated editor will open. However, when double clicking again on a file, it will not open. If you click somewhere out of the Project Explorer and then return to the Project Explorer, then the second double click will work.
Note that right-clicking on the resource and selecting “Open” always works. In addition, in Package Explorer it always works.
I believe this is related to eclipse bugs 285239 and 256761.
Does anyone know of a way that I can overcome this problem, as the RCP developer. The file editor is a custom editor in one of my plugins.
The problem does not seem to happen to me with java files in standard eclipse for java development.
Thanks,
Eyal.
I solved the problem by implementing a setFocus method on the editor class. In the setFocus, I set the focus to some component. (To be precise in my case the editor was a subclass of SharedHeaderFormEditor so I set the focus to the active page).
The truth is that the specification of the setFocus method in IWorkbenchPart requires you to "assign the focus to one of the controls contained in the part's parent composite". It seems that the default implementation of setFocus in some cases did not do that (I don't know why, maybe I was missing something or for other reason).
Note that also setting focus explicitly to a control from within editor initializing partialy solves the problem.
I have the same set of files in N folders, one of them, say, blank.xhtml. The files contain somewhat similar information and it is becoming overwhelming to figure out which file comes from which folder every time I switch between the tabs. When I open one of them to edit and happen to open a file with the same name from another folder I get confused and more often than not end up editing the wrong file: nullifying my hard work. So I am wondering if there is a way to show the name of a containing folder in the tab like this G-06/blank.xhtml or G-07/blank.xhtml. I will be very very thankful to anybody who has pointers to how I can make this happen.
As an addition to the Maroun's answer there is an alternative solution.
It's not exactly what you want (full name in the tab's title), but may be useful sometimes.
In the "Project Explore" view (the same goes to "Navigator" view) click the "Link with Editor" button. That way, whenever you choose some file opened in the editor, it will be automatically selected/highlighted (see the picture) in the "Project Explorer" view.
Here is the picture:
Maybe this will be useful to you too.
If you hover the mouse over the tab containing the file name then a popup appears showing the full path. Not exactly what you wanted, but it should help. (This with Eclipse Neon.3 Release 4.6.3 on a Mac).
Not quite what you're looking for, but ctrl+shft+e will open the switch editor window that shows all the open editors with their filepaths. I use this shortcut for the same reason. I'll have multiple build.gradle files open from multiple projects and this helps pick the correct one
i am making an eclipse plugin which make a ui on right clicking a project in eclipse workspce . the ui contains text fields , package explorer for the current project and directory explorer for current project.
i have successfully made a ui which appears on clicking a menu item on right clicking the project but it seems i can't make any jface or swt ui since they are not visible when we are using eclipse command hadlers .so in order to overcome it i made dialog pages but they have limited dialog like directorty dialog and file dialog and that too for entire window directory..... but i want package explorer and directory explorer for the project i just chose like it happens when u try making a new class in a project the browse buttons just show packages and directory struture w.r.t to current selection
am i doin things wrong or is there a way out please suggest .....
It seems a bit unclear to me, what the 'UI' is about. If you plan to embed the package and directory views inside a dialog next to each other, then I think you have to build similar lists on your own, since they are views with their own event logic. But if you plan to use them via the browse buttons as describes, take a look at this page. It gives a good overview of the available selection dialogs in eclipse.
It is also always a good practice to search for code in eclipse that does nearly the same you want to do.
As an example, take a look at the new class wizard from the jdt.ui plug-in (This is the wizard you mentioned in your question): Press Cmd-Shift-T and begin typing 'newclass' and open NewClassWizardPage from org.eclipse.jdt.ui.wizards. This works as expected if you imported all jdt plug-ins as (binary) projects.
Take a look at the createControl method and dive into the createXXXControls methods via F3 and try to find out how JDT is doing the job.
As an alternative, open the desired selection dialog class (again with Cmd-Shift-T) and open the call hierarchy of that class...
Is there any way to remove binary references from "call hierarchy" (Ctrl-Alt-H) ?
Our project setup is such that for many members we have duplicated references (one reference from source file and one from the jar file with class compiled from that source file). The navigation is inconvenient and I wondering if any ways to fix that is available.
Call hierarchy can be limited in scope to a working set. You just need to set one up to exclude all your libraries.
If you click on the white down arrow in the top right of the Call Hierarchy window a popup menu will appear. Choose Search Scope/Working set and then select or set up the working set you want. A working set can include a source folder or a jar. Once set up your working sets will appear at the bottom of the Search Scope menu so you can access them quickly in future.
I've discovered another way to accomplish this, and since this question is one of the top results in google, I thought it would be good to add it as an answer.
In the Call Hierarchy view, one can click the 'View Menu' (the downward facing arrow) and select "Search In...". In the window that pops up, the user can un-check the options they want to exclude. For example, I only have 'Sources' and 'Required projects' checked.
