SYMPTOMS
========
The MFT_RIGHTORDER style doesn't work as expected (to cause the submenu to
cascade from right to left) when the menu is dynamically created; that is, when
the menu is not loaded from the resource.
For example, a pop-up menu (for example, a menu that contains one submenu,
"color", and one item in the drop-down menu, "red") is created dynamically, by
using the MFT_RIGHTORDER style, in order for the submenu to drop down from right
to left. Currently, because the menu is not loaded from the resource, the
submenu still drops down from left to right, even though the MFT_RIGHTORDER
style is used. See the following code (this code does not work correctly with
MFT_RIGHTORDER):
HMENU hmenu,submenu;
MENUITEMINFO mni, mni2;
char szMenuText[30];
POINT pt;
submenu = CreateMenu();
mni2.fMask= MIIM_DATA|MIIM_TYPE;
mni2.fType = MFT_RIGHTJUSTIFY | MFT_RIGHTORDER | MFT_STRING;
lstrcpy(szMenuText, "red");
mni2.dwTypeData = szMenuText;
mni2.cbSize = sizeof(MENUITEMINFO);
mni2.cch = sizeof(szMenuText);
InsertMenuItem(submenu, 0, TRUE, &mni2);
hmenu = CreatePopupMenu();
mni.fMask= MIIM_DATA|MIIM_TYPE|MIIM_SUBMENU;
mni.fType = MFT_RIGHTJUSTIFY | MFT_RIGHTORDER | MFT_STRING;
lstrcpy(szMenuText, "color");
mni.dwTypeData = szMenuText;
mni.cbSize = sizeof(MENUITEMINFO);
mni.cch = sizeof(szMenuText);
mni.hSubMenu = submenu;
InsertMenuItem(hmenu,0,TRUE,&mni);
pt.x = (long) LOWORD(lParam);
pt.y = (long) HIWORD(lParam);
ClientToScreen(hWnd,&pt);
TrackPopupMenu(hmenu, TPM_RIGHTALIGN,pt.x,pt.y, 0, hWnd,NULL);
RESOLUTION
==========
To use a right-to-left drop-down submenu, you must put the menu in the resource,
and then load the menu at run time, as follows:
// The menu in the resource file resembles the following:
PopupMenu MENUEX DISCARDABLE
BEGIN
POPUP "MOO-Dummy Popup", 65535,
MFT_STRING | MFT_RIGHTORDER | MFT_RIGHTJUSTIFY,MFS_ENABLED
BEGIN
POPUP "Fonts", 65535,
MFT_STRING | MFT_RIGHTORDER | MFT_RIGHTJUSTIFY,MFS_ENABLED
BEGIN
MENUITEM "Courier", IDM_FONT,
MFT_STRING | MFT_RIGHTORDER | MFT_RIGHTJUSTIFY,MFS_ENABLED
MENUITEM "Times Roman", IDM_FONT,
MFT_STRING | MFT_RIGHTORDER | MFT_RIGHTJUSTIFY,MFS_ENABLED
MENUITEM "Swiss", IDM_FONT,
MFT_STRING | MFT_RIGHTORDER | MFT_RIGHTJUSTIFY,MFS_ENABLED
MENUITEM "Helvetica", IDM_FONT,
MFT_STRING | MFT_RIGHTORDER | MFT_RIGHTJUSTIFY,MFS_ENABLED
MENUITEM "Old English", IDM_FONT,
MFT_STRING | MFT_RIGHTORDER | MFT_RIGHTJUSTIFY,MFS_ENABLED
END
POPUP "Sizes", 65535,
MFT_STRING | MFT_RIGHTORDER | MFT_RIGHTJUSTIFY,MFS_ENABLED
BEGIN
MENUITEM "7", IDM_SIZE,MFT_STRING,
MFS_ENABLED
MENUITEM "8", IDM_SIZE,MFT_STRING,
MFS_ENABLED
MENUITEM "9", IDM_SIZE,MFT_STRING,
MFS_ENABLED
MENUITEM "10", IDM_SIZE,MFT_STRING,
MFS_ENABLED
MENUITEM "11", IDM_SIZE,MFT_STRING,
MFS_ENABLED
MENUITEM "12", IDM_SIZE,MFT_STRING,
MFS_ENABLED
MENUITEM "14", IDM_SIZE,MFT_STRING,
MFS_ENABLED
END
POPUP "Styles", 65535,
MFT_STRING | MFT_RIGHTORDER | MFT_RIGHTJUSTIFY,MFS_ENABLED
BEGIN
MENUITEM "Bold", IDM_STYLE,MFT_STRING,
MFS_ENABLED
MENUITEM "Italic", IDM_STYLE,MFT_STRING,
MFS_ENABLED
MENUITEM "Strike Out", IDM_STYLE,MFT_STRING,
MFS_ENABLED
MENUITEM "Superscript", IDM_STYLE,MFT_STRING,
MFS_ENABLED
MENUITEM "Subscript", IDM_STYLE,MFT_STRING,
MFS_ENABLED
END
END
END
The code to load that right-to-left pop-up menu would resemble the following:
HMENU hMenu;
HMENU hMenuTrackPopup;
/* Get the menu for the popup from the resource file. */
hMenu = LoadMenu (hInst, "PopupMenu");
if (!hMenu)
return;
/* Get the first menu in it, which we will use for the call to
* TrackPopup(). This could also have been created on the fly using
* CreatePopupMenu and then we could have used InsertMenu() or
* AppendMenu.
*/
hMenuTrackPopup = GetSubMenu (hMenu, 0);
/* Convert the mouse point to screen coordinates because that is what
* TrackPopup expects.
*/
ClientToScreen (hwnd, (LPPOINT)&point);
/* Draw and track the "floating" pop-up menu. */
TrackPopupMenu (hMenuTrackPopup, 0, point.x, point.y, 0, hwnd, NULL);
/* Destroy the menu because we are done with it. */
DestroyMenu (hMenu);
