QF Test how to get JButton background color?

Question

I'm currently creating a script that requires to verify certain button colors. I can't see any procedures/actions that I can use to verify button colors for swing application.

Is it possible to get JButton color using Javascript or Python script?

Answer 1

Ok, here is a script that adds a corresponding checker. It also knows a "few" more color names (thanks to cindyxiaoxiaoli, see https://stackoverflow.com/a/20670056/3009636 for his color name list) ...

import jarray

componentClass = "java.awt.Component"
backgroundColorCheckerType = DefaultCheckType("BackgroundColor", CheckDataType.STRING, "Background color")

global backgroundColorCheck

# unregister a maybe already present instance of this checker
try: CheckerRegistry.instance().unregisterChecker(componentClass, backgroundColorCheck)
except: pass

# after unregistering, register a new instance of this checker
backgroundColorCheck = BackgroundColorChecker()
CheckerRegistry.instance().registerChecker(componentClass, backgroundColorCheck)

After running this script you can then record the corresponding color check

Answer 2

thanks to @quant, i was able to create a script for this posting it for reference

ColorList = {
"java.awt.Color[r=211,g=211,b=211]": "GRAY",
"java.awt.Color[r=255,g=0,b=0]": "RED",
"java.awt.Color[r=255,g=255,b=0]": "YELLOW",
"java.awt.Color[r=255,g=255,b=102]": "LYELLOW",
"java.awt.Color[r=0,g=255,b=0]": "GREEN"
}

com = rc.getComponent("$(Component)")
RGBcolor = com.getBackground()
foundcolor = ColorList.get(str(RGBcolor))
rc.checkEqual(foundcolor, "$(expectedcolor)", "Check Color")
print (foundcolor)
