财务软件版1楼: 请问怎么样实现不规则窗口，包括三角形。可否使用位图呢？请高手帮忙。谢谢

2楼: BOOL PolyPolygon(
HDC hdc, // handle to DC
CONST POINT *lpPoints, // array of vertices
CONST INT *lpPolyCounts, // array of count of vertices
int nCount // count of polygons
); 如人员信息管理软件

3楼: // 方法一 ：利用不规则图片

(1)
procedure TForm1.FormCreate(Sender: TObject);
begin
self.ClientWidth := HotImage1.Width ;
self.ClientHeight := HotImage1.Height ;
brush.style:=bsClear;
end;

(2)把Form1 的 BorderStyle 属性设置为 bsSizeable

(3)在Form1 上放置一个 TImage,设置其Transparent属性为 true,
并在 TImage.picture 中设置一个不规则图片

// 方法二

procedure TForm1.FormCreate(Sender: TObject);
var
hR : THandle;
begin
// hR := CreateEllipticRgn(self. ,self.top ,self.Width ,self.Height );
hR := CreateEllipticRgn(0,self.height-self.clientHeight,self.clientWidth,self.clientHeight );

SetWindowRgn(Handle,hR,True);
end;

end;

procedure TForm1.Image1MouseUp(Sender: TObject; Button: TMouseButton;
Shift: TShiftState; X, Y: Integer);

MouseLButtonDown:=False; // 鼠标左键弹起
end;


end.

5楼: 这个是以字作窗体，希望对你有点用处！
procedure TForm4.FormPaint(Sender: TObject);
var
rgn:HRGN;
begin
BeginPath(Canvas.Handle);
SetBkMode(Canvas.Handle, TRANSPARENT );
Canvas.Font.Name:= ＇＇宋体＇＇;
Canvas.Font.Size:=100;
Canvas.TextOut( 20, 20, ＇＇Hao＇＇);
EndPath(Canvas.Handle);
rgn:= PathToRegion(Canvas.Handle);
SetWindowRgn(Handle, rgn, true );
end;

6楼: 使用第三方控件吧；
自己写太麻烦了，
写不规则图形，写窗口的paint事件，捕获鼠标消息。处理鼠标，处理标题，处理窗口移动。 多少，自己写？累死你，不过学习还可以。

财务软件版7楼: 谢谢各位的热心讲解。^_^感激[:)]
