based browser

What is the expected output? What do you see instead?
 Expected to see tooltip as rendered by all other browsers. CEFPython browser is not showing the tooltip.

What version of the product are you using? On what operating system?
  cefpython3-27.3-win32-py32

What OS?

Link titles and image alt/titles do work fine for me. Tested on Windows 7 / 
cefpython3 27.3,
using both wxpython.py and cefclient.exe.

Are you able to reproduce the problem with cefclient.exe that is distributed 
with the binaries?

OS is WinXP

Apparently it works with the wx version, but not with win32 api. cefclient also 
shows the tooltip.

Have you tried implementing DisplayHandler.OnTooltip() with return value of 
false?

Yes I have tried and does not seem have any affect. In fact the OnTooltip is 
never even called. In the source, it has comments saying this is yet to be 
implemented: https://code.google.com/p/chromiumembedded/issues/detail?id=783

Regardless, since I found out it works with wx, that gave me a workaround for 
now.

I think that copying the whole ClientHandler class from the wxpython example
to the pywin32 example might fix the tooltip problem. My theory is that one
of the callbacks fixes the problem, by just being called. You could try that,
but it's just a guess.

• Changed title: Tooltip not displayed in pywin32 example
• Changed state: Accepted

I have it copied, and still does not work.

It seems to be related to this issue in CEF:
https://code.google.com/p/chromiumembedded/issues/detail?id=972

The pywin32 examples embed browser in a top window, in the wx example browser 
is embedded in a container, so the parent window is not a top window and that's 
why it works in the wx example.

This might be worth trying:
