Line Control

Creates a control that displays a horizontal, vertical, or diagonal line.


Line

A Line control is a graphical control that displays a horizontal, vertical, or diagonal line that can't be changed directly. However, because a Line control has a full set of properties, events, and methods that other controls have, the Line control can respond to events and can be changed dynamically at run time.

For additional information about creating lines, see the Form Designer topic and Using Controls.

The following example demonstrates how a Line control can be added to a form and how you can use the LineSlant property to specify the direction in which the line slants.

The AddObject method is used to add a Line control to a form. Three command buttons are added to the form, allowing you to change the direction in which the line slants or to close the form.

frmMyForm = CREATEOBJECT('Form')  && Create a Form
frmMyForm.Closable = .F.  && Disable the Control menu box 

frmMyForm.AddObject('shpLine','Line')  && Add a Line control to the form
frmMyForm.AddObject('cmdCmndBtn1','cmdMyCmndBtn1')  && Up Cmnd button
frmMyForm.AddObject('cmdCmndBtn2','cmdMyCmndBtn2')  && Down Cmnd button
frmMyForm.AddObject('cmdCmndBtn3','cmdMyCmndBtn3')  && Quit Cmnd button

frmMyForm.shpLine.Visible = .T.  && Make Line control visible
frmMyForm.shpLine.Top = 20  && Specify Line control row
frmMyForm.shpLine.Left = 125  && Specify Line control column

frmMyForm.cmdCmndBtn1.Visible =.T.  && Up Command button visible
frmMyForm.cmdCmndBtn2.Visible =.T.  && Down" Command button visible
frmMyForm.cmdCmndBtn3.Visible =.T.  && Quit Command button visible

frmMyForm.SHOW  && Display the form
READ EVENTS  && Start event processing

DEFINE CLASS cmdMyCmndBtn1 AS COMMANDBUTTON  && Create Command button
   Caption = 'Slant \<Up'  && Caption on the Command button
   Left = 50  && Command button column
   Top = 100  && Command button row
   Height = 25  && Command button height
   
   PROCEDURE Click
      ThisForm.shpLine.Visible = .F.  && Hide the Line control
      ThisForm.shpLine.LineSlant ='/'  && Slant up
      ThisForm.shpLine.Visible = .T.  && Show the Line control
ENDDEFINE

DEFINE CLASS cmdMyCmndBtn2 AS CommandButton  && Create Command button
   Caption = 'Slant \<Down'  && Caption on the Command button
   Left = 200  && Command button column
   Top = 100  && Command button row
   Height = 25  && Command button height

   PROCEDURE Click
      ThisForm.shpLine.Visible = .F.  && Hide the Line control
      ThisForm.shpLine.LineSlant ='\'  && Slant down
      ThisForm.shpLine.Visible = .T.  && Show the Line control
ENDDEFINE

DEFINE CLASS cmdMyCmndBtn3 AS CommandButton  && Create Command button
   Caption = '\<Quit'  && Caption on the Command button
   Cancel = .T.  && Default Cancel Command button (Esc)
   Left = 125  && Command button column
   Top = 150  && Command button row
   Height = 25  && Command button height

   PROCEDURE Click
      CLEAR EVENTS  && Stop event processing, close Form
