To resize TMSFNCCheckedTreeView into the Form, I need to put it into a Panel (with aligh := alClient) and in the Panel I use Anchors.Left := True, Anchors.Right := True and Anchros.Botton := True.
To avoid this, I suggest creating the Anchors properties in this component.
I also want the ReadOnly property to be created because I need to prevent the user from changing the displayed checks and I can not use Enabled: = False because this inactivates the scrollbar. I tried using Interaction.ReadOnly: = False but it did not have any effect.
