如何最小化任务栏的窗口?(即不图标化) [英] How to minimize a window to the taskbar? (i.e. not iconify)

问题描述

我有一个我想最小化的窗口(到任务栏)，所以我调用 ShowWindow:

ShowWindow(Handle, SW_MINIMIZE);

除了将自身最小化(到任务栏)之外，窗口被图标化:

窗口没有父级:

但这不应该影响这个问题.我正在调用 ShowWindow(..., SW_MINIMIZE) API，而不是最小化窗口，Windows 正在图标化应用程序.

如何最小化任务栏的窗口?

解决方案

任务栏上的那个图标是应用程序(句柄)的图标，而不是 MainForm 的图标.

使用:

Application.Minimize;

但是从你的两个链接中，我知道你已经知道了......呃;)

这适用于 MainForm:

TForm1 = class(TForm)私人的程序 WMSysCommand(var Msg: TWMSysCommand);消息 WM_SYSCOMMAND;受保护过程 CreateParams(var Params: TCreateParams);覆盖；...过程 TForm1.CreateParams(var Params: TCreateParams);开始继承 CreateParams(Params);与参数做开始ExStyle := ExStyle 或 WS_EX_APPWINDOW;WndParent := GetDesktopWindow;结尾;结尾;过程 TForm1.WMSysCommand(var Msg: TWMSysCommand);开始如果 Msg.CmdType = SC_MINIMIZE 那么ShowWindow(句柄，SW_MINIMIZE)别的遗传;结尾;

并从任务栏隐藏 Application.Handle(只有 MainForm 的任务栏图标):将此表单的 Visible 属性设置为 True 并隐藏项目文件中的应用:

Application.Initialize;Application.CreateForm(TForm1, Form1);ShowWindow(Application.Handle, SW_HIDE);应用程序运行；

对于这种形式，ShowWindow(Handle, SW_MINIMIZE); 应该可以工作.它还在最小化或恢复时提供 Windows 的默认缩放功能.

(在 XP 和 W7 上使用 D5 和 D7 进行测试)

i have a window that i want to minimize (to the taskbar), so i call ShowWindow:

ShowWindow(Handle, SW_MINIMIZE);

Except that rather than minimizing itself (to the taskbar), the window is iconified:

The window is unparented:

Update:

Following some advice from 2002, i try setting the WS_EX_APPWINDOW window style and/or ensuring the window has no owner:

Unfortunately, that changes the behavior of my (Delphi) application because there is now two taskbar icons for my application, rather than one:

This, of course, is an artifact of Delphi (5); and because i was trying to solve another issue.

But that shouldn't affect this question. i'm calling the ShowWindow(..., SW_MINIMIZE) API, and rather than minimize the window Windows is iconifying the application.

解决方案

That icon on the taskbar is the icon of the Application (Handle) rather than that of the MainForm.

Use:

Application.Minimize;

Edit: But out of both your links, I understand you knew that already...duh ;)

This works for the MainForm:

TForm1 = class(TForm)
private
  procedure WMSysCommand(var Msg: TWMSysCommand); message WM_SYSCOMMAND;
protected
  procedure CreateParams(var Params: TCreateParams); override;

...

procedure TForm1.CreateParams(var Params: TCreateParams);
begin
  inherited CreateParams(Params);
  with Params do
  begin
    ExStyle := ExStyle or WS_EX_APPWINDOW;
    WndParent := GetDesktopWindow;
  end;
end;

procedure TForm1.WMSysCommand(var Msg: TWMSysCommand);
begin
  if Msg.CmdType = SC_MINIMIZE then
    ShowWindow(Handle, SW_MINIMIZE)
  else
    inherited;
end;

And to hide Application.Handle from the taskbar (to only have a taskbar icon for the MainForm): set the Visible property of this Form to True and hide the Application in the project file:

Application.Initialize;
Application.CreateForm(TForm1, Form1);
ShowWindow(Application.Handle, SW_HIDE);
Application.Run;

For this form, ShowWindow(Handle, SW_MINIMIZE); shóuld work. It also provides for the default zooming-feature of Windows when minimizing or restoring.

(Tested with D5 & D7 on XP and W7)
