bug#20518: 24.5; Tooltip on Ubuntu 12.04/14.04 can't render

[Xiaolong Zhang]

Hi list,

The Dired+ package has a feature that with on a image filename, it will
display a thumbnail of that image. However, it seems that emacs does not
render tooltip correctly on my machine.

Here is a code snippet I used for testing.


-----------8<---------------8<----------------------------------------------- 

;; text in buffer can show image correctly
(insert (propertize "text" 'display (create-image 
"~/Dropbox/images/1.jpg")))

;; tooltip can't render image correctly
(defun get-tooltip(window object pos)
(propertize "tooltip" 'display (create-image "~/Dropbox/images/1.jpg")))
(insert (propertize "text" 'mouse-face 'highlight 'help-echo 'get-tooltip))

-----------8<---------------8<--------------------------------------------

This file line can insert an image rendered in the buffer
correctly. However, the second inserted text only show tooltip text, but
not the image.

I have tested the same code with the same image file on Ubuntu
12.04/14.04 with Emacs (24.5.1) -Q option. Both failed.

I have also tested the code on a Windows 8.1 machine with pre-build
Emacs 24.5. It render the tooltip image correctly.

I'm wondering if this is a bug of Emacs or Ubuntu?

Following is some auto-generated message for bug-report, so I keep it FYI.

Thank you guys!

Best,
Xiaolong

Hi.

C-h f x-gtk-use-system-tooltips <RET>

x-gtk-use-system-tooltips is a variable defined in `C source code'.
Its value is t

Documentation:
If non-nil with a Gtk+ built Emacs, the Gtk+ tooltip is used.
Otherwise use Emacs own tooltip implementation.
When using Gtk+ tooltips, the tooltip face is not used.

You can customize this variable.

System tooltips only support text.  Showing images in tooltips is perverse IMHO.
