**Init, DERIVED PROC**

{{blk2blue.jpg|blk2blue.jpg}}

The **Init **method initializes the QueryListVisual object. Init returns Level:Benign to indicate normal initialization.

The Init method "programs" the QueryListVisual object.

**Implementation:**

The QueryListClass.Ask method (indirectly) calls the Init method to configure the QueryListClass WINDOW.

The Init method reads each queryable item (defined by the QFC property) from a queue, then creates an edit-in-place, 3-column listbox with a field column, an equivalence operator (equal, not equal, greater than, etc.) column, and a value (to query for) column.

The Init method sets the coordinates for the QueryListClass WINDOW and for the individual controls.

**Return Data Type:     **BYTE

**Example:**

**QueryListClass.Ask       PROCEDURE(BYTE UseLast)**

**W WINDOW('Query'),AT(,,300,200),FONT('MS SansSerif',8,,FONT:regular),SYSTEM,GRAY,DOUBLE**

**   LIST,AT(5,5,290,174),USE(?List,FEQ:ListBox),|**

**   FORMAT('91L|M~Field~@s20@44C|M~Operator~L@s10@120C|M~Value~L@s30@')**

**   BUTTON('Insert'),AT(5,183,45,14),USE(?Insert,FEQ:Insert)**

**   BUTTON('Change'),AT(52,183,45,14),USE(?Change,FEQ:Change)**

**   BUTTON('Delete'),AT(99,183,45,14),USE(?Delete,FEQ:Delete)**

**   BUTTON('&OK'),AT(203,183,45,14),USE(?Ok,FEQ:OK),DEFAULT**

**   BUTTON('Cancel'),AT(250,183,45,14),USE(?Cancel,FEQ:Cancel)**

**  END**

** CODE**

** OPEN(W)**

** IF ~UseLast THEN SELF.Reset().**

** RETURN CHOOSE(SELF.Win.Run()=RequestCancelled,Level:Benign,Level:Notify)**
