Example

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
ENDDEFINE
