**Open, VIRTUAL**

{{blk2blue.jpg|blk2blue.jpg}}

The **Open **method prepares the PrintPreviewClass window for initial display. It is designed to execute on window opening events such as EVENT:OpenWindow and EVENT:GainFocus.

**Implementation:**

The Open method sets the window's initial size and position, enables and disables controls as needed, and sets up the specified zoom configuration.

The WindowManager.TakeWindowEvent method calls the Open method.

**Example:**

**ThisWindow.TakeWindowEvent PROCEDURE**

**  CODE**

**  CASE EVENT()**

**  OF EVENT:OpenWindow**

**    IF ~BAND(SELF.Inited,1)**

**      SELF.Open**

**    END**

**  OF EVENT:GainFocus**

**    IF BAND(SELF.Inited,1)**

**      SELF.Reset**

**    ELSE**

**      SELF.Open**

**    END**

**  END**

**  RETURN Level:Benign**
