I am trying to use my mouse's scrollwheel. To do this, I must give focus to the widget which I want to scroll, so I select one of the TableItems in the Problems View. However, doing this throws focus to the editor's control, so the scrollwheel will not scroll through the table. The same for keyboard focus. Clicking on the table is the MOST obvious way to give it focus, so I can then use keyboard to go through the list. I have one-click open enabled. However, clicking on the package explorer opens the editor, but it does NOT throw focus around.
There is a more severe side-effect. My Problems view filter is set to SELECTED_RESOURCE_AND_CHILDREN. If you click on a project, you see all of the project's problems. Then, if you use the problems view to display any 2 problems from the same file, the problems view receives the EditorPart as current selection (because of focus throwing), and this wipes out the list of problems from the project. This happens for keyboard users too who use ENTER key to display the currently selected item in the problems view. The workaround is that you must constantly go back to the navigator/packages view and re-feed the project selection to the problems view.
Still exists in M7
Trying to reproduce on WinXP with I200402170800. Here's what happens to me: When I click on another problem that shows up in the active editor, the editor jumps to the marker I clicked on but focus does not move from the problems view. Single-clicking on markers in other files does not have any effect on the editors. I can't reproduce the focus change problem. Are there any relevant preferences you've changed from their defaults? I can't find the single-click-open preference :-( I did, however, notice the following: If there are two problem markers on the same line and you click on one of them, the selection will sometimes change on its own after a second or so. This does not seem to occur with all problem pairs. Somtimes the selection moves to the other problem on the line and sometimes it simply becomes deselected. The current code in CVS has a warning pair on line 168 of PropertySheetPage.java that demonstrates this behavior.
single-click open is on the main Workbench preference page. Try placing focus on the problem view, and pressing ENTER key twice. The second time focus is thrown.
This problems also exists in the Bookmarks View. IT makes it really hard to delete a bookmark. Single-click is on the very first preference page in Eclipse: "Workbench". You can't miss it :-)
Yet another side-effect of throwing part focus is that fastviews are hidden. So if the problems or tasks view is docked as a fast view, and the user decides to look at warnings/errors, once he has clicked on 2 errors from the same file (or 1 when using double-click), the fast view is hidden, AND its input has been changed to the editor (see comment 2 about SELECTED_RESOURCE_AND_CHILDREN). So then you have to re-open the fast view, then you realize it's not longer displaying your package/project's markers, so you hide it, reselect the project, then reopen the fast view. Then, another problem is that since input was reset on the view, it doesn't maintain selection/scroll location and you have to constantly scroll back to where you were after re-selecting the project. You can reproduce this bug with or without single-click enabled. If using double-click, the same problem of throwing focus exists when double-clicking.
This is working in 3.2 M6
