Method XbpListBox():new() Foundation

Creates an instance of the XbpListBox class.

XbpListBox():new( [<oParent>], ;
                  [<oOwner>], ;
                  [<aPos>], ;
                  [<aSize>], ;
                  [<aPresParam>], ;
                  [<lVisible>] ) --> oXbpListBox
The parent for an XbpListBox object can be optionally specified using the parameter <oParent>. By default <oParent> is the active window (the return value of SetAppWindow()). If the default is used, the active window must be an XbpCrt window. If the active window is an XbpDialog window, the drawing area of the window must be specified for <oParent>. The drawing area is referenced using the instance variable oXbpDialog:drawingArea.
<oOwner> can be used to set the owner for the XbpListBox object. By default <oOwner> is the same as <oParent>.
<aPos> := { nX, nY }
The optional parameter <aPos> can be used to specify the position where the XbpListBox object is displayed. By default, this parameter contains the array {0,0}. This specifies the position for the lower left corner of the XbpListBox object. The first element contains the x coordinate and the second contains the y coordinate. The coordinates are relative to the coordinate system of <oParent>.
<aSize> := { nXsize, nYsize }
The parameter <aSize> optionally specifies the size of the XbpListBox object. <aSize> must be an array containing two elements. The first element specifies the x dimension (width) and the second element specifies the y dimension (height). By default this value is the array {0,0}.
A two dimensional array can be specified for <aPresParam>. Refer to Generic presentation parametersfor a detailed explanation.
The parameter <lVisible> determines whether the XbpListBox object is visible immediately after the call to the method :create(). By default <lVisible> is .T. (true) and the XbpListBox object is displayed after :create() is executed. This default behavior can be suppressed by specifying the value .F. (false) for the parameter <lVisible>. In this case, the XbpListBox object must be explicitly displayed using the :show() method.

The class method :new() returns an XbpListBox object.
