1084 Class providing attributes to be used for the grid cells.
1085
1086 This class both defines an interface which grid cell attributes providers
1087 should implement -- and which can be implemented differently in derived
1088 classes -- and a default implementation of this interface which is often
1089 good enough to be used without modification, especially with not very large
1090 grids for which the efficiency of attributes storage hardly matters (see
1091 the discussion below).
1092
1093 An object of this class can be associated with a wxGrid using
1094 wxGridTableBase::SetAttrProvider() but it's not necessary to call it if you
1095 intend to use the default provider as it is used by wxGridTableBase by
1096 default anyhow.
1097
1098 Notice that while attributes provided by this class can be set for
1099 individual cells using SetAttr() or the entire rows or columns using
1100 SetRowAttr() and SetColAttr() they are always retrieved using GetAttr()
1101 function.
1102
1103
1104 The default implementation of this class stores the attributes passed to
1105 its SetAttr(), SetRowAttr() and SetColAttr() in a straightforward way. A
1106 derived class may use its knowledge about how the attributes are used in
1107 your program to implement it much more efficiently: for example, using a
1108 special background colour for all even-numbered rows can be implemented by
1109 simply returning the same attribute from GetAttr() if the row number is
1110 even instead of having to store N/2 row attributes where N is the total
1111 number of rows in the grid.

1814
1815 wxGrid and its related classes are used for displaying and editing tabular
1816 data. They provide a rich set of features for display, editing, and
1817 interacting with a variety of data sources. For simple applications, and to
1818 help you get started, wxGrid is the only class you need to refer to
1819 directly. It will set up default instances of the other classes and manage
1820 them for you. For more complex applications you can derive your own classes
1821 for custom grid views, grid data tables, cell editors and renderers. The
1822 @ref overview_grid has examples of simple and more complex applications,
1823 explains the relationship between the various grid classes and has a
1824 summary of the keyboard shortcuts and mouse functions provided by wxGrid.
1825
1826 A wxGridTableBase class holds the actual data to be displayed by a wxGrid
1827 class. One or more wxGrid classes may act as a view for one table class.
1828 The default table class is called wxGridStringTable and holds an array of
1829 strings. An instance of such a class is created by CreateGrid().
1830
1831 wxGridCellRenderer is the abstract base class for rendering contents in a
1832 cell. The following renderers are predefined:
1833
1834 - wxGridCellBoolRenderer
1835 - wxGridCellFloatRenderer
1836 - wxGridCellNumberRenderer
1837 - wxGridCellStringRenderer
1838
1839 The look of a cell can be further defined using wxGridCellAttr. An object
1840 of this type may be returned by wxGridTableBase::GetAttr().
1841
1842 wxGridCellEditor is the abstract base class for editing the value of a
1843 cell. The following editors are predefined:
1844
1845 - wxGridCellBoolEditor
1846 - wxGridCellChoiceEditor
1847 - wxGridCellFloatEditor
1848 - wxGridCellNumberEditor
1849 - wxGridCellTextEditor
1850

2246 code itself. This has the advantage of making the grid look and feel
2247 perfectly the same as native applications (using SetUseNativeColLabels()
2248 the grid can be made to look more natively but it still doesn't feel
2249 natively, notably the column resizing and dragging still works slightly
2250 differently as it is implemented in wxWidgets itself) but results in
2251 different behaviour for column and row headers, for which there is no
2252 equivalent function, and, most importantly, is unsuitable for grids
2253 with huge numbers of columns as wxHeaderCtrl doesn't support virtual
2254 mode. Because of this, by default the grid does not use the native
2255 header control but you should call this function to enable it if you
2256 are using the grid to display tabular data and don't have thousands of
2257 columns in it.
2258
2259 Another difference between the default behaviour and the native header
2260 behaviour is that the latter provides the user with a context menu
2261 (which appears on right clicking the header) allowing to rearrange the
2262 grid columns if CanDragColMove() returns @true. If you want to prevent
2263 this from happening for some reason, you need to define a handler for
2264 @c wxEVT_GRID_LABEL_RIGHT_CLICK event which simply does nothing (in
2265 particular doesn't skip the event) as this will prevent the default
2266 right click handling from working.
2267
2268 Also note that currently @c wxEVT_GRID_LABEL_RIGHT_DCLICK event is not
2269 generated for the column labels if the native columns header is used

2622 The data types allow to naturally associate specific renderers and

2624 the grid automatically registers a data type with the name
2625 @c wxGRID_VALUE_STRING which uses wxGridCellStringRenderer and
2626 wxGridCellTextEditor as its renderer and editor respectively -- this is
2627 the data type used by all the cells of the default wxGridStringTable,
2628 so this renderer and editor are used by default for all grid cells.

2630 However if a custom table returns @c wxGRID_VALUE_BOOL from its

2632 wxGridCellBoolEditor are used for it because the grid also registers a
2633 boolean data type with this name.

2635 And as this mechanism is completely generic, you may register your own

2645 and @c wxGRID_VALUE_CHOICE), then the new registration information

4456 used (as it would catch the events from all the grids). The version with @c
4457 CMD takes the id as first argument and the event handler as the second one
4458 and so can be used with multiple grids as well. Otherwise there are no
4459 difference between the two and only the versions without the id are
4460 documented below for brevity.
4461
4462 @beginEventTable{wxGridEvent}
4463 @event{EVT_GRID_CELL_CHANGING(func)}
4464 The user is about to change the data in a cell. The new cell value as
4465 string is available from GetString() event object method. This event
4466 can be vetoed if the change is not allowed.
4467 Processes a @c wxEVT_GRID_CELL_CHANGING event type.
4468 @event{EVT_GRID_CELL_CHANGED(func)}
4469 The user changed the data in a cell. The old cell value as string is
4470 available from GetString() event object method. Notice that vetoing
4471 this event still works for backwards compatibility reasons but any new
4472 code should only veto EVT_GRID_CELL_CHANGING event and not this one.
4473 Processes a @c wxEVT_GRID_CELL_CHANGED event type.
4474 @event{EVT_GRID_CELL_LEFT_CLICK(func)}
4475 The user clicked a cell with the left mouse button. Processes a
4476 @c wxEVT_GRID_CELL_LEFT_CLICK event type.
4477 @event{EVT_GRID_CELL_LEFT_DCLICK(func)}
4478 The user double-clicked a cell with the left mouse button. Processes a
4479 @c wxEVT_GRID_CELL_LEFT_DCLICK event type.
4480 @event{EVT_GRID_CELL_RIGHT_CLICK(func)}
4481 The user clicked a cell with the right mouse button. Processes a
4482 @c wxEVT_GRID_CELL_RIGHT_CLICK event type.
4483 @event{EVT_GRID_CELL_RIGHT_DCLICK(func)}
4484 The user double-clicked a cell with the right mouse button. Processes a
4485 @c wxEVT_GRID_CELL_RIGHT_DCLICK event type.
4486 @event{EVT_GRID_EDITOR_HIDDEN(func)}
4487 The editor for a cell was hidden. Processes a
4488 @c wxEVT_GRID_EDITOR_HIDDEN event type.
4489 @event{EVT_GRID_EDITOR_SHOWN(func)}
4490 The editor for a cell was shown. Processes a
4491 @c wxEVT_GRID_EDITOR_SHOWN event type.
4492 @event{EVT_GRID_LABEL_LEFT_CLICK(func)}
4493 The user clicked a label with the left mouse button. Processes a
4494 @c wxEVT_GRID_LABEL_LEFT_CLICK event type.
4495 @event{EVT_GRID_LABEL_LEFT_DCLICK(func)}
4496 The user double-clicked a label with the left mouse button. Processes a
4497 @c wxEVT_GRID_LABEL_LEFT_DCLICK event type.
4498 @event{EVT_GRID_LABEL_RIGHT_CLICK(func)}
4499 The user clicked a label with the right mouse button. Processes a
4500 @c wxEVT_GRID_LABEL_RIGHT_CLICK event type.
4501 @event{EVT_GRID_LABEL_RIGHT_DCLICK(func)}
4502 The user double-clicked a label with the right mouse button. Processes
4503 a @c wxEVT_GRID_LABEL_RIGHT_DCLICK event type.
4504 @event{EVT_GRID_SELECT_CELL(func)}
4505 The given cell was made current, either by user or by the program via a
4506 call to SetGridCursor() or GoToCell(). Processes a
4507 @c wxEVT_GRID_SELECT_CELL event type.
4508 @event{EVT_GRID_COL_MOVE(func)}
4509 The user tries to change the order of the columns in the grid by
4510 dragging the column specified by GetCol(). This event can be vetoed to
4511 either prevent the user from reordering the column change completely
4512 (but notice that if you don't want to allow it at all, you simply
4513 shouldn't call wxGrid::EnableDragColMove() in the first place), vetoed
4514 but handled in some way in the handler, e.g. by really moving the
4515 column to the new position at the associated table level, or allowed to
4516 proceed in which case wxGrid::SetColPos() is used to reorder the
4517 columns display order without affecting the use of the column indices
4518 otherwise.
4519 This event macro corresponds to @c wxEVT_GRID_COL_MOVE event type.
4520 @event{EVT_GRID_COL_SORT(func)}
4521 This event is generated when a column is clicked by the user and its
4522 name is explained by the fact that the custom reaction to a click on a
4523 column is to sort the grid contents by this column. However the grid
4524 itself has no special support for sorting and it's up to the handler of
4525 this event to update the associated table. But if the event is handled
4526 (and not vetoed) the grid supposes that the table was indeed resorted
4527 and updates the column to indicate the new sort order and refreshes
4528 itself.
4529 This event macro corresponds to @c wxEVT_GRID_COL_SORT event type.
4530 @event{EVT_GRID_TABBING(func)}
4531 This event is generated when the user presses TAB or Shift-TAB in the
4532 grid. It can be used to customize the simple default TAB handling
4533 logic, e.g. to go to the next non-empty cell instead of just the next
4534 cell. See also wxGrid::SetTabBehaviour(). This event is new since
4535 wxWidgets 2.9.5.
