I have configured Eclipse to find bugs using FindBugs. Now I get some error messages in the Markers window. I reviewed them and for a few, I'd like to introduce a SuppressFBWarnings annotation.
How do I obtain the ID for the value attribute of SuppressFBWarnings in Eclipse?
I know I can go to the FindBugs description page, click the item and get the ID, but I wonder whether there's a shorter built-in way. I have already checked whether there is an additional column to be displayed in the Markers window, but there isn't.
Right-click the item in the "Markers" window
Choose "Show Bug Info" from the menu
Scroll to the bottom and get the text near "Pattern:"

There is one weird menu which i need to get rid of. Even when I split vscode environment into more pages (two,three...) it creates this menu for every page area. I have not even find what is the name of this menu, much less how to hide it. Please, does anyone at least know what is the name of this menu?
Those are source control buttons, try to uncheck some of these.
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.
Suppose I make a method signature change that breaks several callers, and I want to review the call sites manually to update them.
Once I change the signature, my "Problems" view shows, say, a dozen errors.
What keys can I hit to navigate through them while leaving the keyboard focus in the editor for fast fixups?
(It's been a while, but I think the Visual Studio equivalent is F8.)
Note that this question does not duplicate Eclipse: How to go to a error using only the keyboard (keyboard-shortcut)?, as that one seeks to navigate only between markers in the current file. In this case, I want to go to the next error regardless of which file it's in.
("Marker" is the general Eclipse term for errors, warnings, etc.)
The best I've come up with so far is Ctrl + F7 to flip to the Problems view, then ↓ to pick the topmost error, then Enter to go to it (which returns focus to the editor).
Here's a way to move to the next error, regardless of editor, in one keystroke. It's not perfect, but it works until it's fixed in Eclipse.
Open a "Markers" view. Click the down arrow at the top right, and choose "Configure Contents". Uncheck the show all box, and create the view to show only the problems you want to see. You'll probably want to deselect "warnings" and "errors" as well. Save it.
Click the same "Markers" down arrow, and choose "Group By". Select "None". This is important because you don't want the parent tree level nodes to show, otherwise some of your "next" actions will take you to those, which don't represent an error.
In Eclipse -> preferences -> keys, search for "Markers". If there is not a keystroke bound to the Markers view, create one. I use Ctrl + Shift + M
Get a keyboard hotkey tool like AutoHotKey (for PC's) or iKey for the Mac. I'm using iKey, but there are plenty of other Mac tools you can use. In your hotkey tool, define an action for the keystroke you want to use for "next error". I chose the standard CMD + .
For that keystroke/action in your hotkey tool, generate 3 keystrokes in the following order:
Ctrl + Shift + M
Down arrow
Enter
Of course, you'll want to change the first one to whatever you picked for yours. You'll probably want to restrict that action to be executed only when Eclipse is the current application.
Save that, create some compile errors, and test it.
Try Ctrl + 3 for Quick access popup window.
If the "Markers view" is not already visible, then type in "markers", in the searchbox on the popup window. Once you have selected it, it should stay available, when you press Ctrl + 3 the next time around.
I just had the same problem, after refactoring some parts of code. I had a lot of errors in different files and i had to go through all of those.
I used the following solution:
Mark all (relevant) entries in the Problems view.
To do this switch to the Problems view using Ctrl+F7 and select the entries with Shift+↓/↑
You can also select all entries using Ctrl+A
Open the marked errors by pressing ↵.
Every file containing at least one marked error will be opened.
The cursor will automatically select one error/file, as if you open only this specific entry
Fix the errors in the opened file.
Here you can use Ctrl+. to navigate to next error inside this file
Close the file using Ctrl+W when your done.
Eclipse will automatically focus the next file and you can go back to step 3
In my case this solution was much faster then switching to the Problems view each time.
There's an Eclipse bug entered for this that has an attachment that looks like it does what you want.
You could use AutoHotkey:
save the mouse position, send a mouse event to click on the arrow in CDT console and then return the mouse back to it's original location. Record the mouse coords with window spy or use autohotkey's search by image function (first capture the images of two arrows with printscreen into bitmaps).
I miss a certain functionality in Eclipse. I would like to know the name of the current function the cursor is currently inside. This is useful when browsing unknown code using the search function, for example.
Any idea how to show it? Maybe a plugin?
I'm using the "Toggle Breadcrumb" option from toolbar:
It shows a nice breadcrumb, ending with current function name.
It's quite handy for me, as Outline becomes cumbersome to use if you have zilions of functions.
It produces the following structure above your Java Editor (truncated at the picture below):
The "Outline" view shows the current function.
It may be necessary to enable the 'Link to Editor' option in the Outline View dropdown menu. This might be off by default for CDT.
I was looking for something similar (Xcode-like bar at the top showing the current function, where you can also go to another function by clicking on it to open a popup list of functions). Here is what I settled on with Eclipse 3.5.1 CDT:
I moved the Outline view to the top, resized it to make it a 1-line horizontal strip (don't make it too narrow), and selected "Link With Editor" in its menu, so that it always shows the current function. However, this doesn't open a popup list like Xcode. For that functionality, I assigned a shortcut to the "Show Outline" command which does open a popup list of all functions.
The Eclipse function 'show outline' will pop up a list of outline objects, and it will highlight the object your cursor is inside in grey. It's typically bound to 'ctrl-o' (the letter 'o', not zero), but you can re-bind it as you see fit. I'm running Eclipse with the CDT plugin and it works pretty well for me.
To enable the breadcrumb invoke Toggle Java Editor Breadcrumb in the toolbar or press Alt+Shift+B in the Java editor.
You can also display the Quick Outline (ctrl+o). This way you see the context quickly without having to have a permanent Outline Window linked to the Editor.
Use the "Link With Editor" option on the outline menu
Press Ctrl+o (cursor is currently inside a function at a particular line).
It highlights the current method, or name of the class if the cursor is outside the method body.
You can click on highlighted method.
It has got inline search feature ...start typing name of the method to navigate to the specified method or method with matching search pattern.
If you press again Ctrl+o to shows the inherited members/methods.
Using outline with "link with editor" option worked also for me, thanks!
Just an addition, you can move outline pane in to the same window group as search, progress etc. saves the space in your perspective instead of keeping it at another group.
