"Matching Preview" of the "Pattern Settings"

--- Is there a way to show only the main screen picture in the "Pattern Settings"?
not in version 1.1.0. will be a feature in version 2.
In multi monitor you always see all monitors and cannot select a specific on.

--- What if I would like to set all my scripts to always operate only in the main monitor.
If you say nothing else, SikuliX always only uses the main monitor.
See the multi monitor section in the docs.

--- What happens if Im creating my scripts in a system with two screens?, but I need to execute them in another system with just one screen?
More than one monitor: SikuliX uses main monitor, if nothing else is said
Only one monitor: SikuliX uses this on ;-)

--- How to perform the findAll inside a small area of the main screen only?
define a Region within the main monitor with the various possibilities/features and say:
matches = list(reg.findAll(image))

Thanks RaiMan,
I just have a doubt,
if Sikuli by default only search in the main monitor in multimonitor system
why it keeps a screencapture of all monitors in the "Matching Preview" of the "Pattern Settings"???

is that because Sikuli search on the secondary monitor if you specify it?
Thanks advanced.

If my script beginn with
App.focus("Chrome")
and then I set a region,
it look in that region only inside chrome right?

@ comment 3
The MatchingPreview looks on all monitors (and it is so currently because of the hardcoded implementation), but find() looks only in the given Region or the main monitor if nothing else is said.

@ comment 4
--- it look in that region only inside chrome right?
that depends on how you set the region.

If my script beginn with App.focus("IrfanView") and then I set a region,
It doesn't matter wich line comes first in the script right? (the App.focus("IrfanView") or the reg = Region())
It worked fine, I doubled the speed
currently Im setting my region this way
reg = Region(x, y, w, h)
and then in every match
matches = list(reg.findAll(image))
But I really would like to search only inside "IrfanView" app
I have notice that, if "IrfanView" is minimized the script runs whitout call it back, I would like to avoid that even when I use App.focus("IrfanView") at the beginning
How should I write the script in order to it to make sure "IrfanView" windows is in focus, is not minized, before set the region

Thanks Advanced.

--- But I really would like to search only inside "IrfanView" app
already looked at:
http://sikulix-2014.readthedocs.org/en/latest/appclass.html#the-application-class-app

where you can find how to get the region of an application window?

---How should I write the script in order to it to make sure "IrfanView" windows is in focus, is not minized, before set the region
Currently SikuliX has no feature, to decide wether an app window is visible or not (e.g. minimised).
You have to decide by looking for something fixed in the window's region, that should be there.
If it is not found, you might try to unhide it by automating the context menu of the task bar icon or double click this icon.

Thanks RaiMan, that solved my question.

Hi RaiMan
Currently I am reading this Sikuli doc (its very extensive)
http://sikulix-2014.readthedocs.org/en/latest/region.html#Region
but I still can't uderstand what you meant by this...
EB--- If my script beginn with
App.focus("Chrome")
and then I set a region,
it look in that region only inside chrome right?
RM--- that depends on how you set the region.

Could you please provide some example or operator name, so I can search for it in the docs?
Thanks Advanced.

Thanks RaiMan, that solved my question.
