# TSizeConstraints.MinHeight

The minimum height for the associated Control.

## Declaration

Source position: controls.pp line 748

`published property TSizeConstraints.MinHeight : TConstraintSize read FMinHeight write SetMinHeight default 0;`

## Description

MinHeight is a TConstraintSize property which contains the minimum height in pixels allowed for the associated Control. The default value for the property is 0 (zero) and indicates that the size constraint has not been assigned and is not enforced.

Changing the value for the property causes assigned (non-zero) values in MaxHeight and MinHeight to be normalized; the smaller of the two values becomes the MinHeight, and the larger of the two values becomes the MaxHeight. The Change method is called to apply the new size constraints to Control, and to signal the OnChange event handler (when assigned).

Use MaxHeight to set minimum height for the associated Control.

Use MaxWidth and MinWidth to set the constrained width for the associated Control.
