ListView_SetItemState (Windows CE 5.0)

Send Feedback

This macro changes the state of an item in a list-view control. You can use this macro or send the LVM_SETITEMSTATE message explicitly.

voidWINAPIListView_SetItemState( HWNDhwnd, inti, UINTstate, UINTmask );

Parameters

• hwnd
  Handle to the list-view control.

• i
  Index of the list-view item. If this parameter is **–**1, then the state change is applied to all items.

• state
  New state bits for the item. The mask parameter indicates the valid bits of the state parameter. The macro ignores bits in the state parameter if the corresponding bit is not set in the mask parameter.

  The low-order byte contains a set of bit flags that indicate the item's state. This byte can be a combination of the following values.

  Value	Description
  LVIS_CUT	The item is marked for a cut-and-paste operation.
  LVIS_DROPHILITED	The item is highlighted as a drag-and-drop target.
  LVIS_FOCUSED	The item has the focus, so it is surrounded by a standard focus rectangle. Although more than one item may be selected, only one item can have the focus.
  LVIS_SELECTED	The item is selected. The appearance of a selected item depends on whether it has the focus and also on the system colors used for selection.

  Bits 8 through 11 of the state parameter specify the one-based index of an overlay image in the control's image lists. Both the full-sized icon image list and the small icon image list can have overlay images. The overlay image is superimposed over the item's icon image. If these bits are zero, the item has no overlay image. To isolate these bits, use the LVIS_OVERLAYMASK mask. To specify an overlay index, use the INDEXTOOVERLAYMASK macro.

  Bits 12 through 15 of the state parameter specify the one-based index of an image in the control's state image list. The state image is displayed next to an item's icon to indicate an application-defined state. If these bits are zero, the item has no state image. To isolate these bits, use the LVIS_STATEIMAGEMASK mask. To specify a state image index, use the INDEXTOSTATEIMAGEMASK macro.

• mask
  Bits of the state parameter that you want to set or clear. You can use ListView_SetItemState both to set and to clear bits. To set an item's overlay image index, set the LVIS_OVERLAYMASK bits. To set an item's state image index, set the LVIS_STATEIMAGEMASK bits.

Return Values

None.

Remarks

An item's state value includes a set of bit flags that indicate the item's state. The state value can also include image list indexes that indicate the item's state image and overlay image.

The mask parameter specifies the state bits you want to modify, and the state parameter specifies the new value for those bits. To set a bit in the item's internal state, set it in both the mask and state parameters. To clear a bit in the item's internal state, set it in the mask parameter and clear it in the state parameter. To leave a bit unchanged in the item's internal state, clear it in the mask parameter.
