RAD Studio VCL Reference
TControl.ConstrainedResize Method

Notify control of resize with constraints.

procedure ConstrainedResize(var MinWidth: Integer; var MinHeight: Integer; var MaxWidth: Integer; var MaxHeight: Integer); virtual;
virtual __fastcall ConstrainedResize(int MinWidth, int MinHeight, int MaxWidth, int MaxHeight);

ConstrainedResize is called automatically when a control is resized and has nonzero Constraints. This allows the control to modify the constraints before they are applied. 

As implemented in TControl, ConstrainedResize simply calls the OnConstrainedResize event handler.
