Go Up to VCL


TStackPanel allows you to order a group of controls inside a container in a single column or row, applying homogeneous alignment, margin, and padding settings to the controls inside the panel. The Orientation property determines the flow of the internal controls, which can be horizontal or vertical.

TStackPanel fully supports VCL styling for Windows 10 and previous versions of Windows.

StackPanel Items Properties

Each control hosted by a StackPanel has additional properties (listed at the bottom of the Object Inspector):

  • The ControlIndex property allows you to change the sequence of the controls in the container.
  • The HorizontalPositioning property allows you to modify the horizontal position of the individual control when you select the vertical orientation. The sphpDefault value assigns the host panel HorizontalPositioning value to the control.
  • The VerticalPositioning property allows you to modify the vertical position of the individual control when you select the horizontal orientation. The sphpDefault value assigns the host panel VerticalPositioning value to the control.
