Left Property

Object List Next Object

Defined By: Window

Description:

Left specifies the horizontal distance between the inner left edge of a form or control and the left side of its container. In combination with the Top property it determines the location for a form or control.

Details:

This value can be set directly by entering the value in the Property Editor or code, or indirectly by moving the object with the mouse. The Left property value is a single-precision number. Keep in mind that the placement of objects looks different on different screen resolutions.

Forms are always measured in twips, and a control is measured in the units specified by the ScaleMode property of its container. Any time the Scale Mode property is changed, the value of the Left property is affected accordingly. For both forms and controls, the Left property's value changes as the object is moved either manually or by code.

The Left property is used in combination with the Top, Width, and Height properties to determine the size and position of an object. However, for operations that require setting more than one of these properties, invoking the Move method of that object is usually more efficient.

Don’t confuse Left, Top, Width, and Height with ScaleLeft, ScaleTop, ScaleWidth, and ScaleHeight. The Scale properties determine the coordinate system of container objects, such as forms, while the size and position properties affect the placement and extent of forms and controls on the screen. Setting the Scale properties will never move a window on the screen or change its size, while setting a size or position property always does.
