Hello World (Windows)ΒΆ

Let us begin with a customary Hello World example!

You will learn how to capture a screenshot of a GUI element and write a Sikuli Script to do two things:

  1. Click on that element
  2. Type a string in that element

The goal of the Hello World script is to automatically type “Hello World” into the Start menu search box, like this:

Now, open the Sikuli IDE. We begin by taking the screenshot of our target, the Start menu symbol that is usually located in the lower-left corner of the desktop. Using this screenshot, we can tell Sikuli script what to click on.

To simulate a mouse click on the Start symbol, we are going to use the click function. To tell Sikuli how the Start symbol look like, we need to capture its image on teh screen.

Sikuli IDE provides two methods to capture screen images. The first method is to click on the camera button in the toolbar. This will bring you to the screen capturing mode.

The second method is to press a hot-key (Ctrl + Shift + 2). Often the target whose image you wish to capture may be covered by the Sikuli IDE’s window. You can minimize the IDE’s window and use this hot-key to switch to the capturing mode.

In the screen capturing mode, the screen will look darker and freeze momentarily. The entire desktop becomes like a canvas where you can draw a rectangle around the target you want to capture an image of. In this case, the target is the Start symbol. The cross of red dotted lines shows the center of the rectangle you just drew.

After you have drawn (or selected) a rectangle, the image within the rectangle will be captured and inserted into the script editor at the current cursor position.

Now, you can write the click function using this image as an argument to tell Sikuli to click on start symbol.

As a convenience, Sikuli IDE provides a Command List on the left panel. It shows a list of the most often used functions. Camera icons in the functions indicate these functions expect a captured image as an argument.

Locate the click() function in the list and click on it. If Auto Capture is on (default), you will be directed to the screen capturing mode in which you can capture an image of an interface target to be inserted into the click() function as an argument.

The next step is to tell Sikuli to enter the string “Hello World” into search box, which can be done with a simple type function.

This function will type the string given in the argument into whichever input control that has the focus. After clicking on the Start symbol, we can expect the search box will be the input that has the focus.

Congratulations! You have just completed your first Sikuli Script. Press the run button to see this script in action!
