Delphi 任務欄中不顯示窗口

目的:ide

1. 窗口不在任務欄顯示。spa

2. 窗口不顯示在Alt+Tab的切換列表中。code

3. 在任務管理器的應用程序列表中不顯示。orm

示例:blog

type TAppWndBrowser = class( TForm ) published
      procedure CreateParams( var Params: TCreateParams ); override; procedure WndProc(var Message: TMessage); override; end; implementation

{$R *.dfm}


{ TAppWndBrowser }
procedure TAppWndBrowser.CreateParams( var Params: TCreateParams ); begin
  inherited CreateParams( Params ); Params.ExStyle := WS_EX_TOOLWINDOW; end; procedure TAppWndBrowser.WndProc(var Message: TMessage); begin
  inherited WndProc(Message); if (not Application.MainFormOnTaskBar) and (Message.Msg = WM_SHOWWINDOW) then
  begin ShowWindow(Application.Handle, SW_HIDE); SetWindowLong(Application.Handle, GWL_EXSTYLE, WS_EX_TOOLWINDOW); end; end;
