Diff Between find and Exists and which method is efficient

find() throws exception, which must be catched for decisions how to proceed.
exists() returns null or a Match object and as such can be used as in your example.

Multi-Monitor Environments

Hi,

I do not how to switch to opened window it is refer Desktop screen of my laptop and taking Screenshot i need to take screenshot in the window which is opened by Selenium
Note: i am using MAC Laptop

CODE:
                WebDriver driver2=new ChromeDriver();
  WebDriverWait wait2 = new WebDriverWait(driver2, 40);
  driver2.get("http://zsal-imac:9090/visitor/index1.html");
  driver2.manage().window().fullscreen();

                Region reg = new Region(413,248,680,510);
  reg.saveScreenCapture("/Users/Desktop/","a");

Kindly help me and share code if possible to focus the region in the website which opened by selenium web driver.

How many monitors are attached to your system including that where the desktop is displayed?

including monitor 3 and if i am set region and trying to click icon which is out that region but it is visible in that page it seld, weather sikuli will click image or not.

Using sikuli 1.1.1

IF possible share some codes to explain region in java.

So you have more than 1 monitor and you have to be sure you have understood SikuliX in a multi-monitor environment.
see comment #4

For the other problem you have another question.

The Region concept and some examples you can find in the docs.
More examples are available in the net: google : sikuli examples
