google chrome drop down windows are missing attributes

[Antoine Martin]

split from #139: we now handle grabs correctly and simulate pressing the Escape key when the application loses focus (since there are no grabs on win32).

The problem with the drop down windows as used by chrome is that they are:

• not using the correct window-type for the drop down, sending it as NORMAL instead
• not grabbing the keyboard or mouse input when the drop down is shown
• not setting the window's transient-for attribute on the temporary window either

I'm not sure there's much we can do about it. Any amount of guessing is bound to break well behaved applications. It would be much easier to get chrome fixed instead.

FWIW: I've tried google chrome 32, and now google chrome beta 33 (which is meant to be using the "aura" toolkit instead of gtk), as well as chromium. No luck with any of them.

Here's a diff of the xwininfo showing the new drop down window as a child of the root window, it should really be a child of the browser window it came from:

The drop down window is 252x302 pixels in dimension.

I have created an upstream bug with chrome: ​chromium #349322

[Antoine Martin]

Nothing we can do about this but wait for upstream to fix their code.

Closing.

[Dweller]

Upstream bug has been archived due to inactivity.. might need a prod, else it'll never be looked at.
