K5 Closing popups(dialogs) from commandline?

[aleq]

This is partly related to my other topic: WebLaunch fullscreen browser crash after few hours

As a hobby project, I'm doing a total conversion of my Jail broken KT. It'll run HTML5 page serving as smart home control panel. The problem is the browser crashes once in a while with "Application Error" popup over the screen. Or if the WiFi is unstable and connection is lost, then the conneciton popup is displayed, even if the connection is restored few seconds later.

Is there any way how to:
- enumerate visible windows/dialogs? To detect there is such popup I want to dismiss?
- close it (this is obviously the most important)

I tried even to stop/restart framework, but that seems not to help at all.
Plus I believe I have seen a topic somewhere here at mobileread.com mentioning a way how to find out visible window or something like that. Unfortunately I haven't saved it and I cannot find it anymore.

Thanks in advance for any tip

It's running the awesome WM (i.e., it's X11), so my gut says "yes", even if you can't find anything better than faking touch input events once you know where to tap, although I've never looked into that myself.

EDIT: There were possibly a few threads playing around the concept with the xdotool utility.

Wooohooo

xwininfo -id `./xdotool getactivewindow` | grep "\"L:D" && ./wmctrl -c :ACTIVE:

Uses xdotool (thanks for the right direction) to get the active window.
Then uses xwininfo to get the window name, if it contains L, it is a dialog
Then uses wmctrl to close the active window gracefully

It may be enough to wmctrl -p -G -l and check for any dialog in the list perhaps
