Height Property

  • Article

Specifies the height of an object on the screen. Available at design time and run time.

Object.Height[ = nHeight]

Property Values

  • nHeight
    Specifies the object's height measured in the unit of measurement specified by the ScaleMode property of the form.

Remarks

For forms, the Height measurement does not include the borders and title bar.

For controls, the height is measured from the outside of the control's border.

The value for this property changes as the object is sized by the user or by code.

Use the Height and Width properties for calculations based on an object's total area.

Note   The Height property is read-only when it applies to a control contained in a Column object.

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
