Shortcut menu for Windows Mobile Development

Today, someone in the Development Group asked you how to press and hold on PPC to bring up a shortcut menu.

Unlike windows, PPC does not rely on responding to the wm_rbuttondown message, but on wm_lbuttondown. It's not surprising that there is no right-click on PPC.

The following code is correct:

......

Case wm_lbuttondown:

{
Shrginfo shrg;
Shrg. cbsize = sizeof (shrg );
Shrg. hwndclient = m_hwnd;
Shrg. ptdown. x = loword (lparam );
Shrg. ptdown. Y = hiword (lparam );
Shrg. dwflags = shrg_returncmd;

Cpoint point;
Point. x = shrg. ptdown. X;
Point. Y = shrg. ptdown. Y;

If (: shrecognizegesture (& shrg) = gn_contextmenu) // long key message
{
Cmenu menu;
Menu. loadmenu (idr_menu_down );

Cmenu * ppopupmenu = menu. getsubmenu (0 );

Clienttoscreen (& Point );

Ppopupmenu-> trackpopupmenu (tpm_leftalign, point. X, point. Y, this );
}

}
