У меня такая проблема: мне нужен многострочный Hint. Помню взял где-то вот такую хрень '...'+#13#10+'...'+ , получается то он многострочный, но почему-то определенной длины. Пробовал я это на RxTrayIcon. Помогите чем можете. Заранее спасибо.

Сам не пробовал....

Пример 1

Код:

unit MHint;

interface

uses
  SysUtils, WinTypes, WinProcs, Messages,
  Classes, Graphics, Controls, Forms, Dialogs;

type
  TMHint = class(TComponent)
  private
    ScreenSize: Integer;
    FActive: Boolean;
    FSeparator: Char;
    FOnShowHint: TShowHintEvent;
  protected
    procedure SetActive(Value: Boolean);
    procedure SetSeparator(Value: char);
    procedure NewHintInfo(var HintStr: string; 
      var CanShow: Boolean;
      var HintInfo: THintInfo);
  public
    constructor Create(AOwner: TComponent); override;
  published
    property Active: Boolean
      read FActive write SetActive;
    property Separator: Char
      read FSeparator write SetSeparator;
  end;

procedure Register;

implementation

constructor TMHint.Create(AOwner: TComponent);

begin
  inherited Create(AOwner);
  FActive := True;
  FSeparator := '@';
  Application.OnShowHint := NewHintInfo;
  ScreenSize := GetSystemMetrics(SM_CYSCREEN);
end;

procedure TMHint.SetActive(Value: Boolean);

begin
  FActive := Value;
end;

procedure TMHint.SetSeparator(Value: Char);

begin
  FSeparator := Value;
end;

procedure TMHint.NewHintInfo(var HintStr: string; 
  var CanShow: Boolean;
  var HintInfo: THintInfo);

var 
  I: Byte;

begin
  if FActive then
    begin
      I := Pos(FSeparator, HintStr);
      while I > 0 do
        begin
          HintStr[i] := #13;
          I := Pos(FSeparator, HintStr);
        end;
      if HintInfo.HintPos.Y+10 > ScreenSize then
        HintInfo.HintPos.Y := ScreenSize-11;
    end;
end;

procedure Register;

begin
  RegisterComponents('MyComponents', [TMHint]);
end;

end.
