Provides information that the owner window uses to determine how to paint an owner-drawn control or menu item. The owner window of the owner-drawn control or menu item receives a pointer to this structure as the lParam parameter of the WM_DRAWITEM message.
Type: UINT
The control type. This member can be one of the following values. See Remarks.
Type: UINT
The identifier of the combo box, list box, button, or static control. This member is not used for a menu item.
Type: UINT
The menu item identifier for a menu item or the index of the item in a list box or combo box. For an empty list box or combo box, this member can be -1. This allows the application to draw only the focus rectangle at the coordinates specified by the rcItem member even though there are no items in the control. This indicates to the user whether the list box or combo box has the focus. How the bits are set in the itemAction member determines whether the rectangle is to be drawn as though the list box or combo box has the focus.
Type: UINT
The required drawing action. This member can be one or more of the values.
Type: UINT
The visual state of the item after the current drawing action takes place. This member can be a combination of the values shown in the following table.
Type: HWND
A handle to the control for combo boxes, list boxes, buttons, and static controls. For menus, this member is a handle to the menu that contains the item.
Type: HDC
A handle to a device context; this device context must be used when performing drawing operations on the control.
Type: RECT
A rectangle that defines the boundaries of the control to be drawn. This rectangle is in the device context specified by the hDC member. The system automatically clips anything that the owner window draws in the device context for combo boxes, list boxes, and buttons, but does not clip menu items. When drawing menu items, the owner window must not draw outside the boundaries of the rectangle defined by the rcItem member.
Type: ULONG_PTR
The application-defined value associated with the menu item. For a control, this parameter specifies the value last assigned to the list box or combo box by the LB_SETITEMDATA or CB_SETITEMDATA message. If the list box or combo box has the LBS_HASSTRINGS or CBS_HASSTRINGS style, this value is initially zero. Otherwise, this value is initially the value that was passed to the list box or combo box in the lParam parameter of one of the following messages:
If CtlType is ODT_BUTTON or ODT_STATIC, itemData is zero.Some control types, such as status bars, do not set the value of CtlType.
