component property check ?

[Alexandre Machado]

I don't know where the information came from.... Property Font is a public property for TIWCustomControl class.

All you need to do is:

if (Self.Components[i] is TIWCustomControl) then
TIWCustomControl(Self.Components[i]).Font.Assign(YourFontHere);

or

if (Self.Components[i] is TIWCustomControl) then
TIWCustomControl(Self.Components[i]).Font.FontFamily := 'Verdana, Helvetica, Sans-Serif';
