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. | |

1747 | ||
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 | ||
1784 | Please see wxGridEvent, wxGridSizeEvent, wxGridRangeSelectEvent, and | |
1785 | wxGridEditorCreatedEvent for the documentation of all event types you can | |
1786 | use with wxGrid. | |

2200 | code itself. This has the advantage of making the grid look and feel | |
2201 | perfectly the same as native applications (using SetUseNativeColLabels() | |
2202 | the grid can be made to look more natively but it still doesn't feel | |
2203 | natively, notably the column resizing and dragging still works slightly | |
2204 | differently as it is implemented in wxWidgets itself) but results in | |
2205 | different behaviour for column and row headers, for which there is no | |
2206 | equivalent function, and, most importantly, is unsuitable for grids | |
2207 | with huge numbers of columns as wxHeaderCtrl doesn't support virtual | |
2208 | mode. Because of this, by default the grid does not use the native | |
2209 | header control but you should call this function to enable it if you | |
2210 | are using the grid to display tabular data and don't have thousands of | |
2211 | columns in it. | |
2212 | ||
2213 | Another difference between the default behaviour and the native header | |
2214 | behaviour is that the latter provides the user with a context menu | |
2215 | (which appears on right clicking the header) allowing to rearrange the | |
2216 | grid columns if CanDragColMove() returns @true. If you want to prevent | |
2217 | this from happening for some reason, you need to define a handler for | |
2218 | @c wxEVT_GRID_LABEL_RIGHT_CLICK event which simply does nothing (in | |
2219 | particular doesn't skip the event) as this will prevent the default | |
2220 | right click handling from working. | |

4291 | This small class can be used to prevent wxGrid from redrawing during its | |
4292 | lifetime by calling wxGrid::BeginBatch() in its constructor and | |
4293 | wxGrid::EndBatch() in its destructor. It is typically used in a function | |
4294 | performing several operations with a grid which would otherwise result in | |
4295 | flicker. For example: | |
4296 | ||
4297 | @code | |
4298 | void MyFrame::Foo() | |
4299 | { | |
4300 | m_grid = new wxGrid(this, ...); | |
4301 | ||
4302 | wxGridUpdateLocker noUpdates(m_grid); | |
4303 | m_grid-AppendColumn(); | |
4304 | // ... many other operations with m_grid ... | |
4305 | m_grid-AppendRow(); | |
4306 | ||
4307 | // destructor called, grid refreshed | |
4308 | } | |
4309 | @endcode | |
4310 | ||
4311 | Using this class is easier and safer than calling wxGrid::BeginBatch() and | |
4312 | wxGrid::EndBatch() because you don't risk missing the call the latter (due | |
4313 | to an exception for example). | |

4353 | @c EVT_GRID_XXX and @c EVT_GRID_CMD_XXX. The only difference between the | |
4354 | two is that the former doesn't allow to specify the grid window identifier | |

4356 | there is more than one grid control in the window where the event table is | |
4357 | used (as it would catch the events from all the grids). The version with @c | |
4358 | CMD takes the id as first argument and the event handler as the second one | |
4359 | and so can be used with multiple grids as well. Otherwise there are no | |
4360 | difference between the two and only the versions without the id are | |
4361 | documented below for brevity. | |

4363 | @beginEventTable{wxGridEvent} | |

4367 | can be vetoed if the change is not allowed. | |
4368 | Processes a @c wxEVT_GRID_CELL_CHANGING event type. | |
4369 | @event{EVT_GRID_CELL_CHANGED(func)} | |
4370 | The user changed the data in a cell. The old cell value as string is | |
4371 | available from GetString() event object method. Notice that vetoing | |
4372 | this event still works for backwards compatibility reasons but any new | |
4373 | code should only veto EVT_GRID_CELL_CHANGING event and not this one. | |
4374 | Processes a @c wxEVT_GRID_CELL_CHANGED event type. | |
4375 | @event{EVT_GRID_CELL_LEFT_CLICK(func)} | |

4385 | The user double-clicked a cell with the right mouse button. Processes a | |
4386 | @c wxEVT_GRID_CELL_RIGHT_DCLICK event type. | |
4387 | @event{EVT_GRID_EDITOR_HIDDEN(func)} | |

4389 | @c wxEVT_GRID_EDITOR_HIDDEN event type. | |
4390 | @event{EVT_GRID_EDITOR_SHOWN(func)} | |
4391 | The editor for a cell was shown. Processes a | |
4392 | @c wxEVT_GRID_EDITOR_SHOWN event type. | |
4393 | @event{EVT_GRID_LABEL_LEFT_CLICK(func)} | |
4394 | The user clicked a label with the left mouse button. Processes a | |
4395 | @c wxEVT_GRID_LABEL_LEFT_CLICK event type. | |
4396 | @event{EVT_GRID_LABEL_LEFT_DCLICK(func)} | |
4397 | The user double-clicked a label with the left mouse button. Processes a | |
4398 | @c wxEVT_GRID_LABEL_LEFT_DCLICK event type. | |
4399 | @event{EVT_GRID_LABEL_RIGHT_CLICK(func)} | |
4400 | The user clicked a label with the right mouse button. Processes a | |
4401 | @c wxEVT_GRID_LABEL_RIGHT_CLICK event type. | |
4402 | @event{EVT_GRID_LABEL_RIGHT_DCLICK(func)} | |
4403 | The user double-clicked a label with the right mouse button. Processes | |
4404 | a @c wxEVT_GRID_LABEL_RIGHT_DCLICK event type. | |
4405 | @event{EVT_GRID_SELECT_CELL(func)} | |
4406 | The given cell was made current, either by user or by the program via a | |
4407 | call to SetGridCursor() or GoToCell(). Processes a | |
4408 | @c wxEVT_GRID_SELECT_CELL event type. | |
4409 | @event{EVT_GRID_COL_MOVE(func)} | |
4410 | The user tries to change the order of the columns in the grid by | |
4411 | dragging the column specified by GetCol(). This event can be vetoed to | |
4412 | either prevent the user from reordering the column change completely | |
4413 | (but notice that if you don't want to allow it at all, you simply | |
4414 | shouldn't call wxGrid::EnableDragColMove() in the first place), vetoed | |
4415 | but handled in some way in the handler, e.g. by really moving the | |
4416 | column to the new position at the associated table level, or allowed to | |
4417 | proceed in which case wxGrid::SetColPos() is used to reorder the | |
4418 | columns display order without affecting the use of the column indices | |
4419 | otherwise. | |
4420 | This event macro corresponds to @c wxEVT_GRID_COL_MOVE event type. | |
4421 | @event{EVT_GRID_COL_SORT(func)} | |
4422 | This event is generated when a column is clicked by the user and its | |
4423 | name is explained by the fact that the custom reaction to a click on a | |
4424 | column is to sort the grid contents by this column. However the grid | |
4425 | itself has no special support for sorting and it's up to the handler of | |
4426 | this event to update the associated table. But if the event is handled | |
4427 | (and not vetoed) the grid supposes that the table was indeed resorted | |
4428 | and updates the column to indicate the new sort order and refreshes | |
4429 | itself. | |
4430 | This event macro corresponds to @c wxEVT_GRID_COL_SORT event type. | |
