Members

cbSize

Value Meaning

dwStyle

Type: DWORD

The menu style. This member can be one or more of the following values.

Value Meaning
MNS_AUTODISMISS
0x10000000
 Menu automatically ends when mouse is outside the menu for approximately 10 seconds.
MNS_CHECKORBMP
0x04000000
 The same space is reserved for the check mark and the bitmap. If the check mark is drawn, the bitmap is not. All checkmarks and bitmaps are aligned. Used for menus where some items use checkmarks and some use bitmaps.
MNS_DRAGDROP
0x20000000
 Menu items are OLE drop targets or drag sources. Menu owner receives WM_MENUDRAG and WM_MENUGETOBJECT messages.
MNS_MODELESS
0x40000000
 Menu is modeless; that is, there is no menu modal message loop while the menu is active.
MNS_NOCHECK
0x80000000
 No space is reserved to the left of an item for a check mark. The item can still be selected, but the check mark will not appear next to the item.
MNS_NOTIFYBYPOS
0x08000000
 Menu owner receives a WM_MENUCOMMAND message instead of a WM_COMMAND message when the user makes a selection. MNS_NOTIFYBYPOS is a menu header style and has no effect when applied to individual sub menus.

cyMax

Type: UINT

The maximum height of the menu in pixels. When the menu items exceed the space available, scroll bars are automatically used. The default (0) is the screen height.

hbrBack

Type: HBRUSH

A handle to the brush to be used for the menu's background.
