我是比较喜欢用MSN的,因为它的信息提示比较独特,所有的聊天软件都是弹出一个常规的WINDOWS对话框,而它却好像是从任务栏里冒出来的。想想了,在DELPHI这样的纯OOP工具里加一个API应该不难实现,花了十来分钟终于搞出来了,以下是实现方法:
1、建立一个APPLICATION,将两个按钮放置到主窗体FROM1中,分别为button1和button2。
button1.caption:='打开窗口';
button2.caption:='关闭窗口';
2、在file菜单项中的new中添加窗体form2,并且在project中的options里,将form2设置为Available froms。
3、以下是FORM2窗体内的控件及属性设置
form2.borderstyle:=bsNone;
添加panel1
panel1.align:=alclient;
panel1.bevellnner:=bvLowered;
可以在panel1内添加你想要的文字。
OK,打开FORM2的代码窗口,代码如下:
unit Unit2;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, ExtCtrls, jpeg, StdCtrls;
type
TForm2 = class(TForm)
Panel1: TPanel;
Image1: TImage;
Label1: TLabel;
procedure Label1Click(Sender: TObject);
procedure Image1Click(Sender: TObject);
private
{ Private declarations }
public
procedure Show;
procedure close;
{ Public declarations }
end;
var
Form2: TForm2;
implementation
procedure tform2.close;
begin
if AnimateWindow(Handle,200,AW_VER_POSITIVE+AW_HIDE)=false then
begin
showmessage('窗体退出出错');
free;
end;
inherited close;
end;
procedure tform2.Show;
begin
top:=430;
left:=560;
if AnimateWindow(Handle,200,AW_VER_NEGATIVE)=false then
begin
showmessage('窗体显示出错');
free;
end;
inherited show;
end;
{$R *.dfm}
以上红色的区域为具体实现特效的代码。为FORM1添加如下代码即可:
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls;
type
TForm1 = class(TForm)
Button1: TButton;
Button2: TButton;
procedure Button1Click(Sender: TObject);
procedure Button2Click(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
uses Unit2;
var
mesfrm:tform2;
{$R *.dfm}
procedure TForm1.Button1Click(Sender: TObject);
begin
mesfrm:=tform2.Create(application);
mesfrm.Show;
end;
procedure TForm1.Button2Click(Sender: TObject);
begin
mesfrm.close;
end;
end.
OK,运行程序你已经可以看到效果了,不过记得将显示器设为800*600象素呵。
由于制作时间较短,只实现了基本的效果,但稍加修改便可和MSN的信息提示一模一样。
