Web development
Specifies the distance between the left edge of a control or form and its container object. Available at design time and run time.
Object.Left[ = nDist] |
Return Value
- nDist
- Specifies the distance between the left edge of an object or form and the left edge of its container object. The default container for a form is the main Visual FoxPro window.
Remarks
Applies To: CheckBox Control | ComboBox Control | CommandButton Control | CommandGroup Control | Container Object | Control Object (Visual FoxPro) | Custom Object | EditBox Control | Form Object | Grid Control | Image Control (Visual FoxPro) | Label Control (Visual FoxPro) | Line Control | ListBox Control | OLE Bound Control | OLE Container Control | OptionButton Control | OptionGroup Control | PageFrame Control | _SCREEN System Variable | Shape Control | Spinner Control | TextBox Control (Visual FoxPro) | Timer Control | ToolBar Object
The Left property specifies how far from the object's zero position the object is located. For example, if a form is contained within the Visual FoxPro main window, the zero position is immediately to the right of the main window's left border. If a toolbar is docked to the left of the main window, the zero position is immediately to the right of the toolbar.
Use Left, Top, Height, and Width properties for operations based on an object's external dimensions, such as moving or resizing. Use the ScaleMode property to change the unit of measurement.
 Note: |
|---|
| The Left property is read-only when it applies to a control contained in a Column object. |
Example
The following example demonstrates how the Left property is used to position controls on a form. The AddObject method is used to add a Line control and three command buttons to a form, and the Left property specifies the horizontal placement of each control on the form.
