HowTo distinguish between enabled and disabled state of a button

Asked by bgbig

I have one situation wherein the 'stop' button disables on GUI when the test is done successfully.

I need to wait on that screen (wait for the 'stop' button to be greyed out ) and then move on to close the window in which this operation is being performed.

I tried the following code :
while exists("img1"): wait(25)
   sleep(1)
    if exists("img2"):
    print "Test Done"
    type(Key.F4,KEY_ALT)

###
where img1='stop' button enabled
            img2='stop' button disabled
and the test takes around 20 seconds to run.
Thanks

To differentiate between a button being enabled/disabled, usually it is sufficient to use:

if exists(Pattern(image_enabled_button).exact():
     print "enabled"
else:
     print "disabled"

This works in situations, where you are sure, that the button is visible at all in one of the 2 states.

In your case (supposing, the button is always in the same place):

option 1:
button = Pattern("img1").exact()
while button.exists(Pattern("img1").exact()):
   wait(1)
print "Test Done"
type(Key.F4,KEY_ALT)

option 2:
button = Pattern("img1").exact()
button.waitVanish(Pattern("img1").exact(), 30)
print "Test Done"
type(Key.F4,KEY_ALT)

In both cases we only look in the region of the button, wether it is still found with a similarity of >0.99.
If the button gets disabled, it produces a similarity of <0.99 and hence is no longer found.

The first version has more flexibility, to handle special situations.

The second version will produce a FindFailed, if the button is visible longer than 30 seconds and uses more cpu (3 searches per second vs. 1 per second with option 1)

one more thing:
The shot of the button should be optimized, so that it contains as little background as possible (cut just around the border of the button including the border)
