Subject: | bug#20934: 24.5; Mouse pointer shape not updated over text when track-mouse enabled |
Date: | Tue, 30 Jun 2015 02:00:06 +0000 |
The mouse pointer shape does not change from an arrow to a bar when hovering over text when in C++ or C major modes and gud-tooltips minor mode.
Only this combination of modes seems cause the problem. The mouse shape is updated in other major modes, ie fundamental etc.
To repeat:
emacs -Q M-x c++-mode M-x gud-tooltip-mode
Move the mouse over the default scratch pad text, and below the text and the mouse point will remain unchanged no matter the position in the window. By default, the mouse cursor will change to a bar over the text and an arrow when away from text.
It seems to be related to the enabling the track-mouse variable to enable mouse events for gud-tooltip mode. This issue can also be repeated by setting track-mouse to t in any mode:
emacs -Q M-: (setq track-mouse t)
I was hoping to implement a semantic tooltip mode for when the mouse hovers over a known keyword, so I was using gud-tooltip-mode for this in standard editing modes.
Tested on Win32 native. Prebuilt install. Not tested on Linux.
