# wxListItem (wx v2.6)

Copy Markdown View Source

This class stores information about a `wxListCtrl` item or column.

`wxListItem` is a class which contains information about:

- Zero based item position; see `setId/2` and `getId/1`.

- Zero based column index; see `setColumn/2` and `getColumn/1`.

- The label (or header for columns); see `setText/2` and `getText/1`.

- The zero based index into an image list; see `getImage/1` and `setImage/2`.

- Application defined data; see `SetData()` (not implemented in wx) and `GetData()` (not implemented in wx).

- For columns only: the width of the column; see `setWidth/2` and `getWidth/1`.

- For columns only: the format of the column; one of `wxLIST_FORMAT_LEFT`, `wxLIST_FORMAT_RIGHT`, `wxLIST_FORMAT_CENTRE`. See `setAlign/2` and `getAlign/1`.

- The state of the item; see `setState/2` and `getState/1`. This is a bitlist of the following flags:

- `wxLIST_STATE_FOCUSED:` The item has the focus.

- `wxLIST_STATE_SELECTED:` The item is selected.

- `wxLIST_STATE_DONTCARE:` No special flags (the value of this constant is 0).

- `wxLIST_STATE_DROPHILITED:` The item is highlighted to receive a drop event. Win32 only.

- `wxLIST_STATE_CUT:` The item is in the cut state. Win32 only.

- A mask indicating which state flags are valid; this is a bitlist of the flags reported above for the item state. See `setStateMask/2` and GetStateMask().

- A mask indicating which fields of this class are valid; see `setMask/2` and `getMask/1`. This is a bitlist of the following flags:

- `wxLIST_MASK_STATE:` The state field is valid.

- `wxLIST_MASK_TEXT:` The label field is valid.

- `wxLIST_MASK_IMAGE:` The image field is valid.

- `wxLIST_MASK_DATA:` The application-defined data field is valid.

- `wxLIST_MASK_WIDTH:` The column width field is valid.

- `wxLIST_MASK_FORMAT:` The column format field is valid.

The `wxListItem` object can also contain item-specific colour and font information: for this you need to call one of `setTextColour/2`, `setBackgroundColour/2` or `setFont/2` functions on it passing it the colour/font to use. If the colour/font is not specified, the default list control colour/font is used.

See: `wxListCtrl`
