How to create a Region from a Pattern?

when working with another IDE like Eclipse or Netbeans, after having put the path to sikuli-script.jar into the relevant plugin path entries (there are other Q&A, talking about that), you should put a

from sikuli.Sikuli import *

at the beginning of a script (which in fact additionally initializes the Sikuli environment).

So you can run your scripts unmodified in these IDE's (no need to qualify).

In your case, it seems that you are calling a class method Region.click(), that needs a region as parameter (unbound means it is not an instance method). The variants of calling click() seems only to be available on the instance level.

There is a globalization mechanism implemented, that during initialization (at time of import) brings all relevant methods in a state, that unqualified usage binds them to SCREEN which is a constant instance of Screen(0). This is a convenience. So even if you say click() the method is bound to an instance of class Screen.

But still in your case, you could repair your problem
(but I recommend the above approach, yours really looks ugly, isn't it ;-):

sikuli.Sikuli.Region.click(sikuli.Sikuli.Region.find(sikuli.Sikuli.Pattern(w7utils.image_path + "menu_home_button.png").similar(0.60)))

or

scr = sikuli.Sikuli.Screen(0)
scr.click(sikuli.Sikuli.Pattern(w7utils.image_path + "menu_home_button.png").similar(0.60))

With Eclipse I did not find a way yet, to tell the Eclipse/PythonPlugin syntax checker to know the Sikuli methods. So you have to live with the "unknown method" hints in the line number column. Netbeans does not have this problem. May be eclipse is more strict with the unqualified usage of methods (which is only solved by Sikuli itself at runtime).
