onMouseMove事件是经常发生的。应该编写一个新Timage构件。
如下:
unit image1;
interface
uses
; Windows, Messages, SysUtils, Classes, Controls, ExtCtrls;
type
; TNewimage = class(TImage)
; private
; ; FOnMouseLeave: TNotifyEvent;
; ; FOnMouseEnter: TNotifyEvent;
; ; { Private declarations }
; protected
; ; { Protected declarations }
; public
; ; { Public declarations }
; published
; ; procedure CMMouseEnter(var Message: TMessage); message CM_MOUSEENTER;
; ; procedure CMMouseLeave(var Message: TMessage); message CM_MOUSELEAVE;
; ; property OnMouseEnter: TNotifyEvent read FOnMouseEnter write FOnMouseEnter;
; ; property OnMouseLeave: TNotifyEvent read FOnMouseLeave write FOnMouseLeave;
; ; { Published declarations }
; end;
procedure Register;
implementation
procedure Register;
begin
//请自己修改
;RegisterComponents('Samples', [TNewimage]);
end;
{ timage1 }
procedure TNewimage.CMMouseEnter(var Message: TMessage);
begin
; inherited;
; if Assigned(FOnMouseEnter) then
; ; FOnMouseEnter(Self);
end;
procedure TNewimage.CMMouseLeave(var Message: TMessage);
begin
; inherited;
; if Assigned(FOnMouseLeave) then
; ; FOnMouseLeave(Self);
end;
end.
