Datatips don't disappear

Hi, When the mouse hovers over a variable, a partial display of the data appears as a tooltip (I think this is called a datatip). The problem is that sometimes it *doesn't disappear*, no matter what I do (minimize the Matlab window, move it around, etc...).

This is extremely annoying as the datatip occludes an important part of the window and prevent me from working normally. So I am often forced to restart matlab, which of course is a big waste of time.

I have been having this problem for a long time, with several operating systems and matlab versions, so it's probably a global problem (maybe it has to do with the way matlab handles windows resources?)

Anyone? -Amir

Maybe a simple question (probably you did this already): did you try right clicking and delete?

[Amir]

Nope - click & delete doesn't work

Try the following. If the figure is the current active figure, use the following:

>> delete(findall(gcf,'Type','hggroup'));

If you know the figure handle, perform the following:

>> delete(findall(handleFigure,'Type','hggroup'));

Thanks Justin, this works without needing to restart Matlab

Thank you so much mr justin.

I actually found some shaky solution : go back to the file where you pointed on the variable to show the tooltip : if the variable V over which the mouse hovered was in foo.m, open foo.m and place the mouse over V . That causes the tooltip to disappear.

It's a petty that this happens, because until I found this solution, I had to restart Matlab as well.

I found that the datatip disappears when I hover on the exact variable from the exact file that poped up the datatip.

This means that when I hover over the variable of the stuck datatip, but from a different file, the datatip remains.

This has annoyed me for a very long time.

I found that if you switch to using cursors in window mode (Tools->Options->Display Cursor In Window), then when you de-select the datatip mode, the datatip window disappears.

I found a way to replicate the problem reliably

1. on a folded cell with significant contents, generate a pop up by folding, then mouse-over onto the %% . . . %%
2. Move the mouse quickly on top of the pop-up
3. very quickly move the mouse away from the pop-up
4. select a different file in the editor. Pop up will persist (undesired behaviour)
5. Then navigate back to original file, and mouse over the original %% . . . %% comment. Voila. Pop-up goes away.

I sent a bug report to TMW just now. Let's see..

[Josh Philipson]

I think another way to make this happen is to be at a breakpoint, mouse-over to generate a tool-tip on the breakpoint line, then step-into the code. Editor jumping to a new file sometimes results in stuck pop-up.

I've seen that too, on rare occasions. Not with datatips, but with other types of tooltip strings, like when you hover over something with the mouse. I figure it's an operating system or Java bug since that looks like the kind of thing they handle, but I'm not sure. Maybe Yair http://undocumentedmatlab.com/ would know.

I also see it from time to time in the editor when I hover the mouse on the ellipsis mark (...) signifying folded code: If the displayed (folded) code is large enough, the tooltip does not go away even if I change the editor file, scroll up/down, etc.

This looks like an internal Matlab bug to me, although I must admit I never reported it (bad me...).

The trick I use in such cases is to find something else in Matlab that displays a tool-tip - this usually causes the previous tooltip to go away.

I am experiencing this issue as well (and I have been in the past since 2 years ago, when I started using Matlab). For me, the trick of finding something else that displays a tooltip does not work: the only solution is to restart Matlab. This is very annoying.

Answer 9

[Spigge]

To me, it seems like this problem occurs more frequently for tooltips that need to be repositioned to fit inside the application window. For example, a tooltip locked to the corner or the side of a window has a higher tendency to get stuck than a "free" toolotip closer to the center. But I really don't have sufficient statistics to say this is always the case.

The function hints window issue occurs on Ubuntu 16.0 and MATLAB Version: 9.1.0.441655 (R2016b)

The hint window can't be moved nor can anything behind it be clicked on. The window is transparent but brighter that what's behind it. I can see the header if I double click on the Ubuntu toolbar Matlab icon and then tab to it.

This did not work

 delete(findall(gcf,'Type','hggroup'));

Only thing I found to work was restarting matlab.
