你要响应消息才行。自定义一个消息,如:WM_USER_TRAYICON为一个整数。增加时加上NIF_MESSAGE标志,IconData.uFlags := IconData.uFlags or NIF_MESSAGE;然后响应WM_USER_TRAYICON消息:判断参数:
if msg.LParam=WM_RBUTTONDOWN then
begin
GetCursorPos( p );
SetForegroundWindow( Handle );
PopupMenu1.Popup( p.x, p.y );
end
else if msg.LParam=WM_LBUTTONDBLCLK then
默认菜单项.Click;别的看API帮助吧。
if msg.LParam=WM_RBUTTONDOWN then
begin
GetCursorPos( p );
SetForegroundWindow( Handle );
PopupMenu1.Popup( p.x, p.y );
end
else if msg.LParam=WM_LBUTTONDBLCLK then
默认菜单项.Click;别的看API帮助吧。
WM_TrayMessage=WM_User+100; protected
procedure AppMinimized(Sender: TObject);
procedure WMTrayMessage(var msg:TMessage);message WM_TrayMessage;uses ShellApivar
NID:TNotifyIconData{点击了任务栏的图标}
procedure TMainForm.WMTrayMessage(var msg:TMessage);
var
p:TPoint;
begin
if msg.LParam=WM_LButtonDown then
begin
ShowWindow(Application.Handle,SW_Show);
Application.Restore;
end
else if msg.LParam=WM_RButtonDown then
begin
GetCursorPos(p);
pmTray.Popup(p.x,p.y);
end;
end;{应用程序最小化时图标显示在任务栏}
procedure TMainForm.AppMinimized(Sender:TObject);
begin
NID.cbSize:=SizeOf(TNotifyIconData);
NID.hIcon:=Application.Icon.Handle;
NID.szTip:= '彩虹2.0 Beta ';
