is there a way of changing the color of the font in a disabled tedit control? i.e is it possible to have the contents displayed in something different than the grey color to show a disabled status ? (for ex: I want red font over white background when control is disabled)

yes but it's quite tricky .
i post a component for you to to it cut n paste and save as DiscEdit.Pas then install component it will be on samples pallette :

unit DisCEdit;


  WinTypes, WinProcs, Messages, SysUtils, Classes, Graphics, Controls,

  TDisabledColorEdit = class(Tedit)
    { Private declarations }
    FEnabled: Boolean;
    FDisabledColor: Tcolor;
    FDisabledFontColor: TColor;
    FOldColor, FOldFontColor: TColor;

    Procedure SetEnabled( value: Boolean );
    Procedure SetDisabledColor( value: TColor );
    Procedure SetDisabledFontColor( value: TColor );
    Procedure SetReadOnly( value: Boolean );
    Function GetReadOnly: Boolean;
    { Protected declarations }
    { Public declarations }

    Constructor Create( aOwner: TComponent ); override;
    { Published declarations }

    property Enabled: Boolean read FEnabled write SetEnabled default true;
    property ReadOnly: Boolean read GetReadOnly write SetReadOnly default
    property DisabledColor: TColor read FDisabledColor write
    property DisabledFontColor: TColor read FDisabledFontColor write

procedure Register;


 Constructor TDisabledColorEdit.Create( aOwner: TComponent );
   FEnabled := True;
   FDisabledColor := clWindowText;
   FDisabledFontColor := clGrayText;
   inherited Create( aOwner );

 Procedure TDisabledColorEdit.SetEnabled( value: Boolean );
   If FEnabled <> value Then Begin
     inherited ReadOnly := not value;
     FEnabled := value;
     If value Then Begin
       Color := FOldColor;
       Font.Color := FOldFontColor;
     Else Begin
       FOldColor := Color;
       FOldFontColor := Font.Color;
       Color := FDisabledColor;
       Font.Color := FDisabledFontColor;

 Procedure TDisabledColorEdit.SetDisabledColor( value: TColor );
   If FDisabledColor <> value Then Begin
     If not FEnabled Then
       Color := value;
     FDisabledColor := value;

 Procedure TDisabledColorEdit.SetDisabledFontColor( value: TColor );
   If FDisabledFontColor <> value Then Begin
     If not FEnabled Then
       Font.Color := value;
     FDisabledFontColor := value;

 Procedure TDisabledColorEdit.SetReadOnly( value: Boolean );
   If FEnabled Then
     inherited ReadOnly := value;

 Function TDisabledColorEdit.GetReadOnly: Boolean;
   result := inherited ReadOnly;

procedure Register;
  RegisterComponents('Samples', [TDisabledColorEdit]);

thanks for your reply,
your component would work correctly but this would give me a control that can get the focus (even though you won't be able to change anything because it's a read-only).  What is needed is the exact same behaviour as diabled i.e. no focus.

any ideas ?

ok to try this put my comp on a form and a button
give my comp some disabledcolors then on button click type this:

    GetWindowLong(DisabledColorEdit1.Handle,GWL_STYLE) or WS_DISABLED);

this will stop it from recieving focus
if you want it to recieve focus type this:

    GetWindowLong(DisabledColorEdit1.Handle,GWL_STYLE) and not WS_DISABLED);

Regards Barry
