首先建議初學(xué)者不要在這些小的技巧上下太多功夫, 學(xué)好基礎(chǔ)才是根本;
我的博客上這種東西不多, 這是大家討論時, 話趕話趕出來的, 知道有這種可行性即可, 沒有多少實(shí)用價值.
本例效果圖:
此例回復(fù)來賓在
http://www.cnblogs.com/del/archive/2008/02/26/1081644.html 碰到的問題.
全部代碼如下(測試時注意給主窗體焦點(diǎn)):
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls, ExtCtrls;
type
TForm1 = class(TForm)
Panel1: TPanel;
Edit1: TEdit;
Button1: TButton;
Button2: TButton;
Timer1: TTimer;
procedure FormCreate(Sender: TObject);
procedure Timer1Timer(Sender: TObject);
procedure Button1Click(Sender: TObject);
procedure Button2Click(Sender: TObject);
end;
var
Form1: TForm1;
implementation
{$R *.dfm}
{這里主要是設(shè)置控件位置}
procedure TForm1.FormCreate(Sender: TObject);
begin
Panel1.Align := alTop;
Panel1.Height := 30;
Edit1.Top := 4;
Edit1.Left := 12;
Edit1.Width := 72;
Edit1.Clear;
Button1.Top := Edit1.Top - 1;
Button1.Left := Edit1.Left + Edit1.Width + 12;
Button1.Caption := '確認(rèn)捕獲, 用回車鍵';
Button1.Width := Canvas.TextWidth(Button1.Caption) + 32;
Button1.Default := True;
Button2.Top := Button1.Top;
Button2.Left := Panel1.ClientWidth - Button2.Width - 12;
Button2.Anchors := [akRight];
Button2.Caption := '過來吧你';
Timer1.Interval := 100;
end;
{捕獲窗口句柄, 顯示在標(biāo)題}
procedure TForm1.Timer1Timer(Sender: TObject);
var
pt: TPoint;
begin
if Boolean(GetCursorPos(pt)) then
Text := IntToStr(WindowFromPoint(pt));
end;
{把確認(rèn)的目標(biāo)窗口的句柄顯示在 Edit1}
procedure TForm1.Button1Click(Sender: TObject);
begin
Edit1.Text := Self.Text;
end;
{捕獲了干什么呢? 譬如讓它當(dāng)自己的"干兒子"吧}
procedure TForm1.Button2Click(Sender: TObject);
var
h: HWND; {這是被捕捉窗口的句柄}
r: TRect; {這是被捕捉窗口的矩形}
pw,ph: Integer; {這是被捕捉窗口的寬度與高度}
begin
h := StrToInt(Edit1.Text);
Windows.SetParent(h, Self.Handle);
GetWindowRect(h,r);
pw := r.Right - r.Left;
ph := r.Bottom - r.Top;
MoveWindow(h, 0, Panel1.Height, pw, ph, True);
end;
end.
發(fā)現(xiàn)還沒處理計算器的關(guān)閉呢, 用處不大, 不再重做了.
