TButton = class(TButtonControl)
private
FDefault: Boolean;
FCancel: Boolean;
FActive: Boolean;
FModalResult: TModalResult;
procedure SetDefault(Value: Boolean);
procedure CMDialogKey(var Message: TCMDialogKey); message CM_DIALOGKEY;
procedure CMDialogChar(var Message: TCMDialogChar); message CM_DIALOGCHAR;
procedure CMFocusChanged(var Message: TCMFocusChanged); message CM_FOCUSCHANGED;
procedure CNCommand(var Message: TWMCommand); message CN_COMMAND;
procedure WMEraseBkgnd(var Message: TWMEraseBkgnd); message WM_ERASEBKGND;
protected
procedure CreateParams(var Params: TCreateParams); override;
procedure CreateWnd; override;
procedure SetButtonStyle(ADefault: Boolean); virtual;
public
constructor Create(AOwner: TComponent); override;
procedure Click; override;
function UseRightToLeftAlignment: Boolean; override;
published
property Action;
property Anchors;
property BiDiMode;
property Cancel: Boolean read FCancel write FCancel default False;
property Caption;
property Constraints;
property Default: Boolean read FDefault write SetDefault default False;
property DragCursor;
property DragKind;
property DragMode;
property Enabled;
property Font;
property ModalResult: TModalResult read FModalResult write FModalResult default 0;
property ParentBiDiMode;
property ParentFont;
property ParentShowHint;
property PopupMenu;
property ShowHint;
property TabOrder;
property TabStop default True;
property Visible;
property OnClick;
property OnContextPopup;
property OnDragDrop;
property OnDragOver;
property OnEndDock;
property OnEndDrag;
property OnEnter;
property OnExit;
property OnKeyDown;
property OnKeyPress;
property OnKeyUp;
property OnMouseDown;
property OnMouseMove;
property OnMouseUp;
property OnStartDock;
property OnStartDrag;
end;
