Members

CtlType
Unsigned integer that specifies the control type. It can be one of the following values:
Value Description
ODT_BUTTON Owner-drawn button
ODT_LISTVIEW Owner-draw list view control
ODT_MENU Owner-drawn menu
ODT_TAB Tab control
CtlID
Unsigned integer that specifies the identifier of the combo box, list box, or button. This member is not used for a menu.
itemID
Unsigned integer that specifies 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 value allows the application to draw only the focus rectangle at the coordinates specified by the rcItemmember, even though the control contains no items. This focus rectangle indicates to the user whether the list box or combo box has the focus. The value of the itemActionmember determines whether the rectangle is to be drawn as though the list box or combo box has the focus.
itemAction
Unsigned integer that specifies the drawing action required. This member can have one or more of the following values:
Value Description
ODA_DRAWENTIRE The entire control needs to be drawn.
ODA_FOCUS The control has lost or gained the keyboard focus. You should check the itemStatemember to determine whether the control has the focus.
ODA_SELECT The selection status has changed. You should check the itemStatemember to determine the new selection state.
itemState
Unsigned integer that specifies the visual state of the item after the current drawing action takes place. It can be a combination of the following values:
Value Description
ODS_CHECKED The menu item is to be checked. Use this value only in a menu.
ODS_COMBOBOXEDIT The drawing takes place in the edit control of an owner-drawn combo box.
ODS_DEFAULT The item is the default item.
ODS_DISABLED The item is to be drawn as disabled.
ODS_FOCUS The item has the keyboard focus.
ODS_GRAYED The item is to be grayed. Use this value only in a menu.
ODS_SELECTED The status of the menu item is selected.
hwndItem
Handle to the control for combo boxes, list boxes, buttons, and static controls. For menus, this member is a handle to the menu containing the item.
hDC
Handle to a device context. You must use this device context when performing drawing operations on the control.
rcItem
RECTstructure that specifies a rectangle that defines the boundaries of the control to be drawn. This rectangle is in the device context that you specified with the hDCmember. The OS 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 rcItemmember.
itemData
Pointer to an unsigned long that specifies the application-defined 32-bit value associated with the menu item. For a control, this member specifies the value last assigned to the list box or combo box by the LB_SETITEMDATAor CB_SETITEMDATAmessage. If the list box or combo box has the LB_HASSTRINGS or CB_HASSTRINGS style, this value is initially zero. Otherwise, this value is initially the value passed to the list box or combo box in the lParamparameter of one of the following messages:
