  28     @class wxHeaderCtrl
  29
  30     wxHeaderCtrl is the control containing the column headings which is usually
  31     used for display of tabular data.
  32
  33     It is used as part of wxGrid, in generic version wxDataViewCtrl and report
  34     view of wxListCtrl but can be also used independently. In general this
  35     class is meant to be used as part of another control which already stores
  36     the column information somewhere as it can't be used directly: instead you
  37     need to inherit from it and implement the GetColumn() method to provide
  38     column information. See wxHeaderCtrlSimple for a concrete control class
  39     which can be used directly.
  40
  41     In addition to labeling the columns, the control has the following
  42     features:
  43         - Column reordering support, either by explicitly configuring the
  44           columns order and calling SetColumnsOrder() or by dragging the
  45           columns interactively (if enabled).
  46         - Display of the icons in the header: this is often used to display a
  47           sort or reverse sort indicator when the column header is clicked.
  48
  49     Notice that this control itself doesn't do anything other than displaying
  50     the column headers. In particular column reordering and sorting must still
  51     be supported by the associated control displaying the real data under the
  52     header. Also remember to call ScrollWindow() method of the control if the
  53     associated data display window has a horizontal scrollbar, otherwise the
  54     headers wouldn't align with the data when the window is scrolled.
  55
  56     This control is implemented using the native header control under MSW
  57     systems and a generic implementation elsewhere.
  58
  59
  60     @section headerctrl_improvements Future Improvements
  61
  62     Some features are supported by the native MSW control and so could be
  63     easily implemented in this version of wxHeaderCtrl but need to be
  64     implemented in the generic version as well to be really useful. Please let
  65     us know if you need or, better, plan to work on implementing, any of them:
  66         - Displaying bitmaps instead of or together with the text
  67         - Custom drawn headers
  68         - Filters associated with a column.

  71     @beginStyleTable
  72     @style{wxHD_ALLOW_REORDER}
  73         If this style is specified (it is by default), the user can reorder
  74         the control columns by dragging them.
  75     @style{wxHD_ALLOW_HIDE}
  76         If this style is specified, the control shows a popup menu allowing the
  77         user to change the columns visibility on right mouse click. Notice that
  78         the program can always hide or show the columns, this style only
  79         affects the users capability to do it.
  80     @style{wxHD_DEFAULT_STYLE}
  81         Symbolic name for the default control style, currently equal to
  82         @c wxHD_ALLOW_REORDER.

  86     @event{EVT_HEADER_CLICK(id, func)}
  87         A column heading was clicked.
  88     @event{EVT_HEADER_RIGHT_CLICK(id, func)}
  89         A column heading was right clicked.
  90     @event{EVT_HEADER_MIDDLE_CLICK(id, func)}
  91         A column heading was clicked with the middle mouse button.
  92     @event{EVT_HEADER_DCLICK(id, func)}
  93         A column heading was double clicked.
  94     @event{EVT_HEADER_RIGHT_DCLICK(id, func)}
  95         A column heading was right double clicked.
  96     @event{EVT_HEADER_MIDDLE_DCLICK(id, func)}
  97         A column heading was double clicked with the middle mouse button.
  98     @event{EVT_HEADER_SEPARATOR_DCLICK(id, func)}
  99         Separator to the right of the specified column was double clicked
 100         (this action is commonly used to resize the column to fit its
 101         contents width and the control provides UpdateColumnWidthToFit() method
 102         to make implementing this easier).
 103     @event{EVT_HEADER_BEGIN_RESIZE(id, func)}
 104         The user started to drag the separator to the right of the column
 105         with the specified index (this can only happen for the columns for
 106         which wxHeaderColumn::IsResizeable() returns true). The event can
 107         be vetoed to prevent the column from being resized. If it isn't,
 108         the resizing and end resize (or dragging cancelled) events will be
 109         generated later.
 110     @event{EVT_HEADER_RESIZING(id, func)}
 111         The user is dragging the column with the specified index resizing
 112         it and its current width is wxHeaderCtrlEvent::GetWidth().
 113         The event can be vetoed to stop the dragging operation completely at
 114         any time.
 115     @event{EVT_HEADER_END_RESIZE(id, func)}
 116         The user stopped dragging the column by releasing the mouse.
 117         The column should normally be resized to the value of
 118         wxHeaderCtrlEvent::GetWidth().
 119     @event{EVT_HEADER_BEGIN_REORDER(id, func)}
 120         The user started to drag the column with the specified index (this
 121         can only happen for the controls with wxHD_ALLOW_REORDER style).
 122         This event can be vetoed to prevent the column from being reordered,
 123         otherwise the end reorder message will be generated later.
 124     @event{EVT_HEADER_END_REORDER(id, func)}
 125         The user dropped the column in its new location. The event can be
 126         vetoed to prevent the column from being placed at the new position
 127         or handled to update the display of the data in the associated
 128         control to match the new column location (available from
 129         wxHeaderCtrlEvent::GetNewOrder()).
 130     @event{EVT_HEADER_DRAGGING_CANCELLED(id, func)}
 131         The resizing or reordering operation currently in progress was
 132         cancelled. This can happen if the user pressed Esc key while
 133         dragging the mouse or the mouse capture was lost for some other
 134         reason. You only need to handle this event if your application
 135         entered into some modal mode when resizing or reordering began, in
 136         which case it should handle this event in addition to the matching
 137         end resizing or reordering ones.
