1014
1015 wxGrid and its related classes are used for displaying and editing tabular
1016 data. They provide a rich set of features for display, editing, and
1017 interacting with a variety of data sources. For simple applications, and to
1018 help you get started, wxGrid is the only class you need to refer to
1019 directly. It will set up default instances of the other classes and manage
1020 them for you. For more complex applications you can derive your own classes
1021 for custom grid views, grid data tables, cell editors and renderers. The
1022 @ref overview_grid has examples of simple and more complex applications,
1023 explains the relationship between the various grid classes and has a
1024 summary of the keyboard shortcuts and mouse functions provided by wxGrid.
1025
1026 A wxGridTableBase class holds the actual data to be displayed by a wxGrid
1027 class. One or more wxGrid classes may act as a view for one table class.
1028 The default table class is called wxGridStringTable and holds an array of
1029 strings. An instance of such a class is created by CreateGrid().
1030
1031 wxGridCellRenderer is the abstract base class for rendereing contents in a
1032 cell. The following renderers are predefined:
1033
1034 - wxGridCellBoolRenderer
1035 - wxGridCellFloatRenderer
1036 - wxGridCellNumberRenderer
1037 - wxGridCellStringRenderer
1038
1039 The look of a cell can be further defined using wxGridCellAttr. An object
1040 of this type may be returned by wxGridTableBase::GetAttr().
1041
1042 wxGridCellEditor is the abstract base class for editing the value of a
1043 cell. The following editors are predefined:
1044
1045 - wxGridCellBoolEditor
1046 - wxGridCellChoiceEditor
1047 - wxGridCellFloatEditor
1048 - wxGridCellNumberEditor
1049 - wxGridCellTextEditor
1050
1051 Please see wxGridEvent, wxGridSizeEvent, wxGridRangeSelectEvent, and
1052 wxGridEditorCreatedEvent for the documentation of all event types you can
1053 use with wxGrid.

1396 the grid can be made to look more natively but it still doesn't feel
1397 natively, notably the column resizing and dragging still works slightly

3237 Notice that all grid event table macros are available in two versions:
3238 @c EVT_GRID_XXX and @c EVT_GRID_CMD_XXX. The only difference between the
3239 two is that the former doesn't allow to specify the grid window identifier
3240 and so takes a single parameter, the event handler, but is not suitable if
3241 there is more than one grid control in the window where the event table is
3242 used (as it would catch the events from all the grids). The version with @c
3243 CMD takes the id as first argument and the event handler as the second one
3244 and so can be used with multiple grids as well. Otherwise there are no
3245 difference between the two and only the versions without the id are
3246 documented below for brevity.
3247
3248 @beginEventTable{wxGridEvent}
3249 @event{EVT_GRID_CELL_CHANGE(func)}
3250 The user changed the data in a cell. Processes a
3251 @c wxEVT_GRID_CELL_CHANGE event type.
3252 @event{EVT_GRID_CELL_LEFT_CLICK(func)}
3253 The user clicked a cell with the left mouse button. Processes a
3254 @c wxEVT_GRID_CELL_LEFT_CLICK event type.
3255 @event{EVT_GRID_CELL_LEFT_DCLICK(func)}
3256 The user double-clicked a cell with the left mouse button. Processes a
3257 @c wxEVT_GRID_CELL_LEFT_DCLICK event type.
3258 @event{EVT_GRID_CELL_RIGHT_CLICK(func)}
3259 The user clicked a cell with the right mouse button. Processes a
3260 @c wxEVT_GRID_CELL_RIGHT_CLICK event type.
3261 @event{EVT_GRID_CELL_RIGHT_DCLICK(func)}
3262 The user double-clicked a cell with the right mouse button. Processes a
3263 @c wxEVT_GRID_CELL_RIGHT_DCLICK event type.
3264 @event{EVT_GRID_EDITOR_HIDDEN(func)}
3265 The editor for a cell was hidden. Processes a
3266 @c wxEVT_GRID_EDITOR_HIDDEN event type.
3267 @event{EVT_GRID_EDITOR_SHOWN(func)}
3268 The editor for a cell was shown. Processes a
3269 @c wxEVT_GRID_EDITOR_SHOWN event type.
3270 @event{EVT_GRID_LABEL_LEFT_CLICK(func)}
3271 The user clicked a label with the left mouse button. Processes a
3272 @c wxEVT_GRID_LABEL_LEFT_CLICK event type.
3273 @event{EVT_GRID_LABEL_LEFT_DCLICK(func)}
3274 The user double-clicked a label with the left mouse button. Processes a
3275 @c wxEVT_GRID_LABEL_LEFT_DCLICK event type.
3276 @event{EVT_GRID_LABEL_RIGHT_CLICK(func)}
3277 The user clicked a label with the right mouse button. Processes a
3278 @c wxEVT_GRID_LABEL_RIGHT_CLICK event type.
3279 @event{EVT_GRID_LABEL_RIGHT_DCLICK(func)}
3280 The user double-clicked a label with the right mouse button. Processes
3281 a @c wxEVT_GRID_LABEL_RIGHT_DCLICK event type.
3282 @event{EVT_GRID_SELECT_CELL(func)}
3283 The user moved to, and selected a cell. Processes a
3284 @c wxEVT_GRID_SELECT_CELL event type.
3285 @event{EVT_GRID_COL_MOVE(func)}
3286 The user tries to change the order of the columns in the grid by
3287 dragging the column specified by GetCol(). This event can be vetoed to
3288 either prevent the user from reordering the column change completely
3289 (but notice that if you don't want to allow it at all, you simply
3290 shouldn't call wxGrid::EnableDragColMove() in the first place), vetoed
3291 but handled in some way in the handler, e.g. by really moving the
3292 column to the new position at the associated table level, or allowed to
3293 proceed in which case wxGrid::SetColPos() is used to reorder the
3294 columns display order without affecting the use of the column indices
3295 otherwise.
3296
3297 This event macro corresponds to @c wxEVT_GRID_COL_MOVE event type.
3298 @event{EVT_GRID_COL_SORT(func)}
3299 This event is generated when a column is clicked by the user and its
3300 name is explained by the fact that the custom reaction to a click on a
3301 column is to sort the grid contents by this column. However the grid
3302 itself has no special support for sorting and it's up to the handler of
3303 this event to update the associated table. But if the event is handled
3304 (and not vetoed) the grid supposes that the table was indeed resorted
3305 and updates the column to indicate the new sort order and refreshes
3306 itself.
3307
3308 This event macro corresponds to @c wxEVT_GRID_COL_SORT event type.
