SikuliX

Not working methods of the class App - close(), focus(),

Asked by Alexandr

I have the following code taken from the documentation.

firefox = App.open(r"C:\Program Files (x86)\Mozilla Firefox\firefox.exe")
wait(2)
#firefox.focus()
wait(1)
firefox.close()

When I call the method of focus() or wait(). I get an error

[error] script [ HappyDev ] stopped with error in line 5
[error] AttributeError ( 'NoneType' object has no attribute 'close' )
In the previous version SikuliX these methods worked fine. Could you tell me how to solve this problem

I can't run previous version of SikuliX now, but the following code works correctly on SikuliX1.1.0 .
[Environment:]Windows7, SikuliX1.1.0
[code:]
myApp = App("firefox")
App.open(r"C:\Program Files\Mozilla Firefox\firefox.exe")
while not myApp.isRunning():
        wait(1)
myApp.focus()
myApp.close()

You are having this problem because of how you define your firefox variable.

When you write:
firefox = App.open(r"C:\Program Files (x86)\Mozilla Firefox\firefox.exe")

you assign the output of whatever value that is created as a result of EXECUTING the FireFox browser

The error:
[error] AttributeError ( 'NoneType' object has no attribute 'close' )

says exactly that.

To make it work properly, you must do it like was offered by @masuo and first create an instance of the type App. The you will be able to use the App methods on it.

Can you help with this problem?
