[request] Ubuntu: app.window() returns None - not supported on Linux yet

Bug Description

Ubuntu 10.10 32Bit and 64Bit / Sikuli X-1.0rc2 (32Bit and 64Bit)

only App.open(), App.close() and App.focus() work

app.window()/App.focusedWindow() can return the region of the application's window on Mac and Window. However, it returns NONE on Ubuntu.

For instance, the following code results in error on Ubuntu, but works well on Mac and Windows.
ff = App("firefox")
print ff.window().getY()

I have lost the track, since I always build from the current source, if something is fixed in Sikuli.

There has been a problem, that App.window() did not return a full featured Region object.

The workaround was, to force it a Region object:

print Region(ff.window()).getY()

so give it a try.

BTW: What Sikuli version?

Thanks RaiMan for your rapid response. I tried your suggestion, it doesn't work either.
I use 1.0rc2 x86.

I just noticed the following information at http://sikuli.org/docx/new-in-sikulix.html.
Will Sikuli support this on Linux later on?

New App Class replaces the old openApp, switchApp, closeApp functions (see Class App)

App.open(), App.close(), App.focus()
App.window() returns the bound of the app window as a Region, so you can restrict following actions within that region. (Windows and Mac only)

it really seems to be a current bug.

pls. tell your Ubuntu version.

I have changed the bug description accordingly.

You got it - thanks.

I knew something about that, but did not remember where it was written.

XWininfo is an easy workaround on Linux.
Maybe Sikuli should also use it to implement this feature.

Here's a patch
Note that some linux programs are started by batch files, like in ubuntu firefox is a batch file that starts firefox-bin

So after doing App.open() you'll have to start a new App('firefox-bin') to use that window.

I found a bug here,
The original patch can't search appName through all tailing string of winLine with space characters, It often fails.
Since my source has been formatted so i can't make a patch, so i just provide a fix here.

=== modified file 'sikuli-script/src/main/java/org/sikuli/script/LinuxUtil.java'
- if(!ok && winLine[7].toLowerCase().indexOf(appName)>=0) {
- ok=true;
- }
+ int from = str.indexOf(winLine[7]);
+ if (!ok && str.substring(from).toLowerCase().indexOf(appName) >= 0) {
+ ok = true;
+ }
