How to minimize a window to the taskbar? (i.e. not iconify)
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.
