1097
1098 wxGrid and its related classes are used for displaying and editing tabular
1099 data. They provide a rich set of features for display, editing, and
1100 interacting with a variety of data sources. For simple applications, and to
1101 help you get started, wxGrid is the only class you need to refer to
1102 directly. It will set up default instances of the other classes and manage
1103 them for you. For more complex applications you can derive your own classes
1104 for custom grid views, grid data tables, cell editors and renderers. The
1105 @ref overview_grid has examples of simple and more complex applications,
1106 explains the relationship between the various grid classes and has a
1107 summary of the keyboard shortcuts and mouse functions provided by wxGrid.
1108
1109 A wxGridTableBase class holds the actual data to be displayed by a wxGrid
1110 class. One or more wxGrid classes may act as a view for one table class.
1111 The default table class is called wxGridStringTable and holds an array of
1112 strings. An instance of such a class is created by CreateGrid().
1113
1114 wxGridCellRenderer is the abstract base class for rendereing contents in a
1115 cell. The following renderers are predefined:
1116
1117 - wxGridCellBoolRenderer
1118 - wxGridCellFloatRenderer
1119 - wxGridCellNumberRenderer
1120 - wxGridCellStringRenderer
1121
1122 The look of a cell can be further defined using wxGridCellAttr. An object
1123 of this type may be returned by wxGridTableBase::GetAttr().
1124
1125 wxGridCellEditor is the abstract base class for editing the value of a
1126 cell. The following editors are predefined:
1127
1128 - wxGridCellBoolEditor
1129 - wxGridCellChoiceEditor
1130 - wxGridCellFloatEditor
1131 - wxGridCellNumberEditor
1132 - wxGridCellTextEditor
1133

3381 wxGrid::EndBatch() in its destructor. It is typically used in a function
3382 performing several operations with a grid which would otherwise result in
3383 flicker. For example:
3384
3385 @code
3386 void MyFrame::Foo()
3387 {
3388 m_grid = new wxGrid(this, ...);
3389

3393 m_grid-AppendRow();
3394
3395 // destructor called, grid refreshed
3396 }
3397 @endcode
3398
3399 Using this class is easier and safer than calling wxGrid::BeginBatch() and

3441 @c EVT_GRID_XXX and @c EVT_GRID_CMD_XXX. The only difference between the
3442 two is that the former doesn't allow to specify the grid window identifier
3443 and so takes a single parameter, the event handler, but is not suitable if
3444 there is more than one grid control in the window where the event table is
3445 used (as it would catch the events from all the grids). The version with @c
3446 CMD takes the id as first argument and the event handler as the second one
3447 and so can be used with multiple grids as well. Otherwise there are no
3448 difference between the two and only the versions without the id are
3449 documented below for brevity.
3450
3451 @beginEventTable{wxGridEvent}
3452 @event{EVT_GRID_CELL_CHANGING(func)}
3453 The user is about to change the data in a cell. The new cell value as
3454 string is available from GetString() event object method. This event
3455 can be vetoed if the change is not allowed.
3456 Processes a @c wxEVT_GRID_CELL_CHANGING event type.
3457 @event{EVT_GRID_CELL_CHANGED(func)}
3458 The user changed the data in a cell. The old cell value as string is
3459 available from GetString() event object method. Notice that vetoing
3460 this event still works for backwards compatibility reasons but any new
3461 code should only veto EVT_GRID_CELL_CHANGING event and not this one.
3462 Processes a @c wxEVT_GRID_CELL_CHANGED event type.
3463 @event{EVT_GRID_CELL_LEFT_CLICK(func)}
3464 The user clicked a cell with the left mouse button. Processes a
3465 @c wxEVT_GRID_CELL_LEFT_CLICK event type.
3466 @event{EVT_GRID_CELL_LEFT_DCLICK(func)}
3467 The user double-clicked a cell with the left mouse button. Processes a
3468 @c wxEVT_GRID_CELL_LEFT_DCLICK event type.
3469 @event{EVT_GRID_CELL_RIGHT_CLICK(func)}
3470 The user clicked a cell with the right mouse button. Processes a
3471 @c wxEVT_GRID_CELL_RIGHT_CLICK event type.
3472 @event{EVT_GRID_CELL_RIGHT_DCLICK(func)}
3473 The user double-clicked a cell with the right mouse button. Processes a
3474 @c wxEVT_GRID_CELL_RIGHT_DCLICK event type.
3475 @event{EVT_GRID_EDITOR_HIDDEN(func)}
3476 The editor for a cell was hidden. Processes a
3477 @c wxEVT_GRID_EDITOR_HIDDEN event type.
3478 @event{EVT_GRID_EDITOR_SHOWN(func)}
3479 The editor for a cell was shown. Processes a
3480 @c wxEVT_GRID_EDITOR_SHOWN event type.
3481 @event{EVT_GRID_LABEL_LEFT_CLICK(func)}
3482 The user clicked a label with the left mouse button. Processes a
3483 @c wxEVT_GRID_LABEL_LEFT_CLICK event type.
3484 @event{EVT_GRID_LABEL_LEFT_DCLICK(func)}
3485 The user double-clicked a label with the left mouse button. Processes a
3486 @c wxEVT_GRID_LABEL_LEFT_DCLICK event type.
3487 @event{EVT_GRID_LABEL_RIGHT_CLICK(func)}
3488 The user clicked a label with the right mouse button. Processes a
3489 @c wxEVT_GRID_LABEL_RIGHT_CLICK event type.
3490 @event{EVT_GRID_LABEL_RIGHT_DCLICK(func)}
3491 The user double-clicked a label with the right mouse button. Processes
3492 a @c wxEVT_GRID_LABEL_RIGHT_DCLICK event type.
3493 @event{EVT_GRID_SELECT_CELL(func)}
3494 The user moved to, and selected a cell. Processes a
3495 @c wxEVT_GRID_SELECT_CELL event type.
3496 @event{EVT_GRID_COL_MOVE(func)}
3497 The user tries to change the order of the columns in the grid by
3498 dragging the column specified by GetCol(). This event can be vetoed to
3499 either prevent the user from reordering the column change completely
3500 (but notice that if you don't want to allow it at all, you simply
3501 shouldn't call wxGrid::EnableDragColMove() in the first place), vetoed
3502 but handled in some way in the handler, e.g. by really moving the
3503 column to the new position at the associated table level, or allowed to
3504 proceed in which case wxGrid::SetColPos() is used to reorder the
3505 columns display order without affecting the use of the column indices
3506 otherwise.
3507 This event macro corresponds to @c wxEVT_GRID_COL_MOVE event type.
3508 @event{EVT_GRID_COL_SORT(func)}
3509 This event is generated when a column is clicked by the user and its
3510 name is explained by the fact that the custom reaction to a click on a
3511 column is to sort the grid contents by this column. However the grid
3512 itself has no special support for sorting and it's up to the handler of
3513 this event to update the associated table. But if the event is handled
3514 (and not vetoed) the grid supposes that the table was indeed resorted
3515 and updates the column to indicate the new sort order and refreshes
3516 itself.
3517 This event macro corresponds to @c wxEVT_GRID_COL_SORT event type.
