Inheritance diagram for wxListItem:Detailed Description
This class stores information about a wxListCtrl item or column.
wxListItem is a class which contains information about:
- Zero based item position; see SetId() and GetId().
- Zero based column index; see SetColumn() and GetColumn().
- The label (or header for columns); see SetText() and GetText().
- The zero based index into an image list; see GetImage() and SetImage().
- Application defined data; see SetData() and GetData().
- For columns only: the width of the column; see SetWidth() and GetWidth().
- For columns only: the format of the column; one of
wxLIST_FORMAT_LEFT,wxLIST_FORMAT_RIGHT,wxLIST_FORMAT_CENTRE. See SetAlign() and GetAlign(). - The state of the item; see SetState() and GetState(). 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() and GetStateMask().
- A mask indicating which fields of this class are valid; see SetMask() and GetMask(). 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(), SetBackgroundColour() or SetFont() 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.
