Yes it is one of the better features of DelphiX that, for example the DXDraw component is automatically resizeable, unlike most other DX interfaces.

At its simplest, my development work puts a DXDraw on a form with a panel aligned to the bottom with buttons and labels for debug tests and reports. When ready for distribution, the panel is hidden.

For more complex work and, just plain explorative tests, the DXDraw component is aligned to the left with a slider control and a memo aligned to the client where each routine sends a report line.
