Is there a way to determine if scrollbars are visible on a TDBGrid

Question

I want to display something in the bottom right of a TDBGrid, but I don't want to overwrite the scrollbars.

Is there a nice way of determining if the scrollbars are visible? (and their size)

You could simply use the `ClientRect` property which is the rect not occupied by scroll bars. Compare with the `BoundsRect` property. — Andreas Rejbrand, Feb 22 '21 at 21:39

Probably the best approach is to use the ClientRect property, which gives the client rectangle of the control in its own coordinates (which implies that Left and Top are always 0). The "client rectangle" is the part of the control which is not border and scroll bar.

For comparison, the BoundsRect property is the full rectangle of the window in the parent window's coordinate system.

For example,

and

pnSnowman.SetBounds(
  DBGrid1.Left + DBGrid1.ClientWidth - pnSnowman.Width - 8,
  DBGrid1.Top + DBGrid1.ClientHeight - pnSnowman.Height - 8,
  pnSnowman.Width,
  pnSnowman.Height
);

results in

Thanks, a nice explanation as well as code example. – Alister Feb 23 '21 at 01:15 — Alister, Feb 23 '21 at 01:15
