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

[Message part 1 (text/plain, inline)]

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.
