Hi:
How can the TIcon be disabled? For example a button can be disabled and I would like to do same with an Icon so when the user clicks on the icon, nothing happens.

Thanks,
Trinione

you need to disable it in code

Icon1.Enabled := false;

It has the Enabled property, just not in object inspector.

Great! Thanks. That works.

However, the following does not work.

   if ctrl.Controls[i] is TIcon then
   begin
     ico := TIcon(ctrl.Controls[i]);
     ico.Enabled := bol;
   end;

This works fine here.

Make sure your ctrl is actual direct parent of the icon and bol has the
value you want.

I would recommend using the TIconButton in such a case.  It has support for a disabled state, as well as showing a pushed state.  The TIcon is only intended to be used for displaying icons, period.

Tim:
This is for a general routine to disable the components based on their type. So, there would be times when a TIcon would be need to be disabled also.

I am not seeing information or an example on how to set the TIConButton disabled state though.

Yes, but as I said, the TIcon *isn't designed to be used this way*.  In other words, don't expect changes to this effect when there's a TIconButton control that *does* behave in the manner that you want.

This is an oversight, in terms of published properties.  A fix will be in 2.06 B3.

However, at run-time you can still do this:

MyIconButton.Enabled:=False;
