Description
Use the Rect.Left property to get or set the horizontal (X) coordinate of the rectangle’s left edge (relative to the screen).
Declaration
RectObj.Left
| Read-Write Property | Integer |
| RectObj | An expression, variable or parameter that specifies a reference to a Rect object | |||
Applies To
The property is applied to the following object:
Property Value
The horizontal coordinate of the rectangle’s left edge, in screen coordinates.
Example
The code below demonstrates how you can search for the desired image on a web page. To search the window, we use the Picture.Find method. This method returns a rectangle that specifies the coordinates of the image within the web browser window. To calculate the coordinates of the image center, we use methods of the Rect object. To obtain the scripting object corresponding to the found image, we use the Sys.Desktop.ObjectFromPoint method. This method returns an onscreen object that contains Click and other actions, which you can use to simulate mouse clicks over the image.
