The problem comes when I want to change anything else, such as the background colour (color) because the documentation doesn't list the property names that you need to pass to the function SetProperty. For example the only reason I knew to use 'Caption.Text' is because it was in the example. I have tried 'Background.Color', 'Presentation.Color' and many other variants but with no luck.
I do not have that directory but I have seen reference to it on other posts I have read. It appeared to me to be from older versions of QlikView? If not, then please could you upload a copy so I can see if it is any help?
Does this tell you the required property name to change the background colour (color) of a line/arrow object for example?
