14 cell or to wxGrid::SetDefaultRenderer() to change the view of all cells.
15 This is an abstract class, and you will normally use one of the predefined
16 derived classes or derive your own class from it.

1064 Class providing attributes to be used for the grid cells.
1065
1066 This class both defines an interface which grid cell attributes providers
1067 should implement -- and which can be implemented differently in derived
1068 classes -- and a default implementation of this interface which is often
1069 good enough to be used without modification, especially with not very large
1070 grids for which the efficiency of attributes storage hardly matters (see
1071 the discussion below).
1072
1073 An object of this class can be associated with a wxGrid using
1074 wxGridTableBase::SetAttrProvider() but it's not necessary to call it if you
1075 intend to use the default provider as it is used by wxGridTableBase by
1076 default anyhow.
1077
1078 Notice that while attributes provided by this class can be set for
1079 individual cells using SetAttr() or the entire rows or columns using
1080 SetRowAttr() and SetColAttr() they are always retrieved using GetAttr()
1081 function.
1082
1083
1084 The default implementation of this class stores the attributes passed to
1085 its SetAttr(), SetRowAttr() and SetColAttr() in a straightforward way. A
1086 derived class may use its knowledge about how the attributes are used in
1087 your program to implement it much more efficiently: for example, using a
1088 special background colour for all even-numbered rows can be implemented by
1089 simply returning the same attribute from GetAttr() if the row number is
1090 even instead of having to store N/2 row attributes where N is the total
1091 number of rows in the grid.

1748 wxGrid and its related classes are used for displaying and editing tabular
1749 data. They provide a rich set of features for display, editing, and
1750 interacting with a variety of data sources. For simple applications, and to
1751 help you get started, wxGrid is the only class you need to refer to
1752 directly. It will set up default instances of the other classes and manage
1753 them for you. For more complex applications you can derive your own classes
1754 for custom grid views, grid data tables, cell editors and renderers. The
1755 @ref overview_grid has examples of simple and more complex applications,
1756 explains the relationship between the various grid classes and has a
1757 summary of the keyboard shortcuts and mouse functions provided by wxGrid.
1758
1759 A wxGridTableBase class holds the actual data to be displayed by a wxGrid
1760 class. One or more wxGrid classes may act as a view for one table class.
1761 The default table class is called wxGridStringTable and holds an array of
1762 strings. An instance of such a class is created by CreateGrid().
1763
1764 wxGridCellRenderer is the abstract base class for rendering contents in a
1765 cell. The following renderers are predefined:
1766
1767 - wxGridCellBoolRenderer
1768 - wxGridCellFloatRenderer
1769 - wxGridCellNumberRenderer
1770 - wxGridCellStringRenderer
1771
1772 The look of a cell can be further defined using wxGridCellAttr. An object
1773 of this type may be returned by wxGridTableBase::GetAttr().
1774
1775 wxGridCellEditor is the abstract base class for editing the value of a
1776 cell. The following editors are predefined:
1777
1778 - wxGridCellBoolEditor
1779 - wxGridCellChoiceEditor
1780 - wxGridCellFloatEditor
1781 - wxGridCellNumberEditor
1782 - wxGridCellTextEditor
1783

2221 If this function is called with @true argument, a wxHeaderCtrl is used

2223 code itself. This has the advantage of making the grid look and feel
2224 perfectly the same as native applications (using SetUseNativeColLabels()
2225 the grid can be made to look more natively but it still doesn't feel
2226 natively, notably the column resizing and dragging still works slightly
2227 differently as it is implemented in wxWidgets itself) but results in
2228 different behaviour for column and row headers, for which there is no
2229 equivalent function, and, most importantly, is unsuitable for grids
2230 with huge numbers of columns as wxHeaderCtrl doesn't support virtual
2231 mode. Because of this, by default the grid does not use the native
2232 header control but you should call this function to enable it if you
2233 are using the grid to display tabular data and don't have thousands of
2234 columns in it.
2235
2236 Another difference between the default behaviour and the native header
2237 behaviour is that the latter provides the user with a context menu
2238 (which appears on right clicking the header) allowing to rearrange the
2239 grid columns if CanDragColMove() returns @true. If you want to prevent
2240 this from happening for some reason, you need to define a handler for
2241 @c wxEVT_GRID_LABEL_RIGHT_CLICK event which simply does nothing (in
2242 particular doesn't skip the event) as this will prevent the default
2243 right click handling from working.
2244
2245 Also note that currently @c wxEVT_GRID_LABEL_RIGHT_DCLICK event is not
2246 generated for the column labels if the native columns header is used

2597 Register a new data type.
2598
2599 The data types allow to naturally associate specific renderers and
2600 editors to the cells containing values of the given type. For example,
2601 the grid automatically registers a data type with the name
2602 @c wxGRID_VALUE_STRING which uses wxGridCellStringRenderer and
2603 wxGridCellTextEditor as its renderer and editor respectively -- this is
2604 the data type used by all the cells of the default wxGridStringTable,
2605 so this renderer and editor are used by default for all grid cells.
2606
2607 However if a custom table returns @c wxGRID_VALUE_BOOL from its
2608 wxGridTableBase::GetTypeName() method, then wxGridCellBoolRenderer and
2609 wxGridCellBoolEditor are used for it because the grid also registers a
2610 boolean data type with this name.
2611
2612 And as this mechanism is completely generic, you may register your own
2613 data types using your own custom renderers and editors. Just remember
2614 that the table must identify a cell as being of the given type for them
2615 to be used for this cell.
2616
2617 @param typeName
2618 Name of the new type. May be any string, but if the type name is
2619 the same as the name of an already registered type, including one
2620 of the standard ones (which are @c wxGRID_VALUE_STRING, @c
2621 wxGRID_VALUE_BOOL, @c wxGRID_VALUE_NUMBER, @c wxGRID_VALUE_FLOAT
2622 and @c wxGRID_VALUE_CHOICE), then the new registration information
2623 replaces the previously used renderer and editor.
2624 @param renderer
2625 The renderer to use for the cells of this type. Its ownership is
2626 taken by the grid, i.e. it will call DecRef() on this pointer when
2627 it doesn't need it any longer.
2628 @param editor
2629 The editor to use for the cells of this type. Its ownership is also

4449 code should only veto EVT_GRID_CELL_CHANGING event and not this one.
4450 Processes a @c wxEVT_GRID_CELL_CHANGED event type.
4451 @event{EVT_GRID_CELL_LEFT_CLICK(func)}
4452 The user clicked a cell with the left mouse button. Processes a
4453 @c wxEVT_GRID_CELL_LEFT_CLICK event type.
4454 @event{EVT_GRID_CELL_LEFT_DCLICK(func)}
4455 The user double-clicked a cell with the left mouse button. Processes a
4456 @c wxEVT_GRID_CELL_LEFT_DCLICK event type.
4457 @event{EVT_GRID_CELL_RIGHT_CLICK(func)}
4458 The user clicked a cell with the right mouse button. Processes a
4459 @c wxEVT_GRID_CELL_RIGHT_CLICK event type.
4460 @event{EVT_GRID_CELL_RIGHT_DCLICK(func)}
4461 The user double-clicked a cell with the right mouse button. Processes a
4462 @c wxEVT_GRID_CELL_RIGHT_DCLICK event type.
4463 @event{EVT_GRID_EDITOR_HIDDEN(func)}
4464 The editor for a cell was hidden. Processes a
4465 @c wxEVT_GRID_EDITOR_HIDDEN event type.
4466 @event{EVT_GRID_EDITOR_SHOWN(func)}
4467 The editor for a cell was shown. Processes a
4468 @c wxEVT_GRID_EDITOR_SHOWN event type.
4469 @event{EVT_GRID_LABEL_LEFT_CLICK(func)}
4470 The user clicked a label with the left mouse button. Processes a
4471 @c wxEVT_GRID_LABEL_LEFT_CLICK event type.
4472 @event{EVT_GRID_LABEL_LEFT_DCLICK(func)}
4473 The user double-clicked a label with the left mouse button. Processes a
4474 @c wxEVT_GRID_LABEL_LEFT_DCLICK event type.
4475 @event{EVT_GRID_LABEL_RIGHT_CLICK(func)}
4476 The user clicked a label with the right mouse button. Processes a
4477 @c wxEVT_GRID_LABEL_RIGHT_CLICK event type.
4478 @event{EVT_GRID_LABEL_RIGHT_DCLICK(func)}
4479 The user double-clicked a label with the right mouse button. Processes
4480 a @c wxEVT_GRID_LABEL_RIGHT_DCLICK event type.
4481 @event{EVT_GRID_SELECT_CELL(func)}
4482 The given cell was made current, either by user or by the program via a
4483 call to SetGridCursor() or GoToCell(). Processes a
4484 @c wxEVT_GRID_SELECT_CELL event type.
4485 @event{EVT_GRID_COL_MOVE(func)}
4486 The user tries to change the order of the columns in the grid by
4487 dragging the column specified by GetCol(). This event can be vetoed to
4488 either prevent the user from reordering the column change completely
4489 (but notice that if you don't want to allow it at all, you simply
4490 shouldn't call wxGrid::EnableDragColMove() in the first place), vetoed
4491 but handled in some way in the handler, e.g. by really moving the
4492 column to the new position at the associated table level, or allowed to
4493 proceed in which case wxGrid::SetColPos() is used to reorder the
4494 columns display order without affecting the use of the column indices
4495 otherwise.
4496 This event macro corresponds to @c wxEVT_GRID_COL_MOVE event type.
4497 @event{EVT_GRID_COL_SORT(func)}
4498 This event is generated when a column is clicked by the user and its
4499 name is explained by the fact that the custom reaction to a click on a
4500 column is to sort the grid contents by this column. However the grid
4501 itself has no special support for sorting and it's up to the handler of
4502 this event to update the associated table. But if the event is handled
4503 (and not vetoed) the grid supposes that the table was indeed resorted
4504 and updates the column to indicate the new sort order and refreshes
4505 itself.
4506 This event macro corresponds to @c wxEVT_GRID_COL_SORT event type.
4507 @event{EVT_GRID_TABBING(func)}
4508 This event is generated when the user presses TAB or Shift-TAB in the
4509 grid. It can be used to customize the simple default TAB handling
4510 logic, e.g. to go to the next non-empty cell instead of just the next
4511 cell. See also wxGrid::SetTabBehaviour(). This event is new since
4512 wxWidgets 2.9.5.
