130 @class wxDataViewModel
131 @wxheader{dataview.h}
133 wxDataViewModel is the base class for all data model to be
134 displayed by a wxDataViewCtrl.
135 All other models derive from it and must implement its
136 pure virtual functions in order to define a complete
137 data model. In detail, you need to override
138 wxDataViewModel::IsContainer,
139 wxDataViewModel::GetParent,
140 wxDataViewModel::GetChildren,
141 wxDataViewModel::GetColumnCount,
142 wxDataViewModel::GetColumnType and
143 wxDataViewModel::GetValue in order to
144 define the data model which acts as an interface between
145 your actual data and the wxDataViewCtrl. Since you will
146 usually also allow the wxDataViewCtrl to change your data
147 through its graphical interface, you will also have to override
148 wxDataViewModel::SetValue which the
149 wxDataViewCtrl will call when a change to some data has been
152 wxDataViewModel (as indeed the entire wxDataViewCtrl
153 code) is using wxVariant to store data and
154 its type in a generic way. wxVariant can be extended to contain
155 almost any data without changes to the original class.
157 The data that is presented through this data model is expected
158 to change at run-time. You need to inform the data model when
159 a change happened. Depending on what happened you need to call
160 one of the following methods:
161 wxDataViewModel::ValueChanged,
162 wxDataViewModel::ItemAdded,
163 wxDataViewModel::ItemDeleted,
164 wxDataViewModel::ItemChanged,
165 wxDataViewModel::Cleared. There are
166 plural forms for notification of addition, change
167 or removal of several item at once. See
168 wxDataViewModel::ItemsAdded,
169 wxDataViewModel::ItemsDeleted,
170 wxDataViewModel::ItemsChanged.
172 Note that wxDataViewModel does not define the position or
173 index of any item in the control because different controls
174 might display the same data differently. wxDataViewModel does
175 provide a wxDataViewModel::Compare method
176 which the wxDataViewCtrl may use to sort the data either
177 in conjunction with a column header or without (see
178 wxDataViewModel::HasDefaultCompare).
180 This class maintains a list of
181 wxDataViewModelNotifier
182 which link this class to the specific implementations on the
183 supported platforms so that e.g. calling
184 wxDataViewModel::ValueChanged
185 on this model will just call
186 wxDataViewModelNotifier::ValueChanged
187 for each notifier that has been added. You can also add
188 your own notifier in order to get informed about any changes
189 to the data in the list model.
191 Currently wxWidgets provides the following models apart
193 wxDataViewIndexListModel,
194 wxDataViewVirtualListModel,
197 Note that wxDataViewModel is reference counted, derives from
198 wxObjectRefData and cannot be deleted
199 directly as it can be shared by several wxDataViewCtrls. This
200 implies that you need to decrease the reference count after
201 associating the model with a control like this:
204 wxDataViewCtrl *musicCtrl = new wxDataViewCtrl( this, ID_MUSIC_CTRL );
205 wxDataViewModel *musicModel = new MyMusicModel;
206 m_musicCtrl-AssociateModel( musicModel );
207 musicModel-DecRef(); // avoid memory leak !!
215 class wxDataViewModel
: public wxObjectRefData
224 Destructor. This should not be called directly. Use DecRef() instead.
229 Adds a wxDataViewModelNotifier
232 void AddNotifier(wxDataViewModelNotifier
* notifier
);
235 Called to inform the model that all data has been cleared. The
236 control will reread the data from the model again.
238 virtual bool Cleared();
241 The compare function to be used by control. The default compare function
242 sorts by container and other items separately and in ascending order.
243 Override this for a different sorting behaviour.
244 See also HasDefaultCompare().
246 virtual int Compare(const wxDataViewItem
& item1
,
247 const wxDataViewItem
& item2
,
252 Oberride this to indicate that the item has special font attributes.
253 This only affects the
254 wxDataViewTextRendererText() renderer.
255 See also wxDataViewItemAttr.
257 bool GetAttr(const wxDataViewItem
& item
, unsigned int col
,
258 wxDataViewItemAttr
& attr
);
261 Override this so the control can query the child items of
262 an item. Returns the number of items.
264 virtual unsigned int GetChildren(const wxDataViewItem
& item
,
265 wxDataViewItemArray
& children
) const;
268 Override this to indicate the number of columns in the model.
270 virtual unsigned int GetColumnCount() const;
273 Override this to indicate what type of data is stored in the
274 column specified by @e col. This should return a string
275 indicating the type of data as reported by wxVariant.
277 virtual wxString
GetColumnType(unsigned int col
) const;
280 Override this to indicate which wxDataViewItem representing the parent
281 of @a item or an invalid wxDataViewItem if the the root item is
284 virtual wxDataViewItem
GetParent(const wxDataViewItem
& item
) const;
287 Override this to indicate the value of @e item
288 A wxVariant is used to store the data.
290 virtual void GetValue(wxVariant
& variant
,
291 const wxDataViewItem
& item
,
292 unsigned int col
) const;
295 Override this method to indicate if a container item merely
296 acts as a headline (or for categorisation) or if it also
297 acts a normal item with entries for futher columns. By
298 default returns @e @false.
300 virtual bool HasContainerColumns(const wxDataViewItem
& item
) const;
303 Override this to indicate that the model provides a default compare
304 function that the control should use if no wxDataViewColumn has been
305 chosen for sorting. Usually, the user clicks on a column header for
306 sorting, the data will be sorted alphanumerically. If any other
307 order (e.g. by index or order of appearance) is required, then this
308 should be used. See also wxDataViewIndexListModel
309 for a model which makes use of this.
311 virtual bool HasDefaultCompare() const;
314 Override this to indicate of @a item is a container, i.e. if
315 it can have child items.
317 virtual bool IsContainer(const wxDataViewItem
& item
) const;
320 Call this to inform the model that an item has been added
323 virtual bool ItemAdded(const wxDataViewItem
& parent
,
324 const wxDataViewItem
& item
);
327 Call this to inform the model that an item has changed.
328 This will eventually emit a wxEVT_DATAVIEW_ITEM_VALUE_CHANGED
329 event (in which the column fields will not be set) to the user.
331 virtual bool ItemChanged(const wxDataViewItem
& item
);
334 Call this to inform the model that an item has been deleted from the data.
336 virtual bool ItemDeleted(const wxDataViewItem
& parent
,
337 const wxDataViewItem
& item
);
340 Call this to inform the model that several items have been added
343 virtual bool ItemsAdded(const wxDataViewItem
& parent
,
344 const wxDataViewItemArray
& items
);
347 Call this to inform the model that several items have changed.
348 This will eventually emit wxEVT_DATAVIEW_ITEM_VALUE_CHANGED
349 events (in which the column fields will not be set) to the user.
351 virtual bool ItemsChanged(const wxDataViewItemArray
& items
);
354 Call this to inform the model that several items have been deleted.
356 virtual bool ItemsDeleted(const wxDataViewItem
& parent
,
357 const wxDataViewItemArray
& items
);
360 Remove the @a notifier from the list of notifiers.
362 void RemoveNotifier(wxDataViewModelNotifier
* notifier
);
365 Call this to initiate a resort after the sort function has
368 virtual void Resort();
371 This gets called in order to set a value in the data model.
372 The most common scenario is that the wxDataViewCtrl calls
373 this method after the user changed some data in the view.
374 Afterwards ValueChanged()
377 virtual bool SetValue(const wxVariant
& variant
,
378 const wxDataViewItem
& item
,
382 Call this to inform this model that a value in the model has
383 been changed. This is also called from wxDataViewCtrl's
384 internal editing code, e.g. when editing a text field
386 This will eventually emit a wxEVT_DATAVIEW_ITEM_VALUE_CHANGED
389 virtual bool ValueChanged(const wxDataViewItem
& item
,
397 @class wxDataViewIndexListModel
398 @wxheader{dataview.h}
400 wxDataViewIndexListModel is a specialized data model which lets
401 you address an item by its position (row) rather than its
402 wxDataViewItem (which you can obtain from this class).
403 This model also provides its own wxDataViewIndexListModel::Compare
404 method which sorts the model's data by the index.
406 This model is not a virtual model since the control stores
407 each wxDataViewItem. Use wxDataViewVirtualListModel if you
408 need to display millions of items or have other reason to
409 use a virtual control.
414 class wxDataViewIndexListModel
: public wxDataViewModel
420 wxDataViewIndexListModel(unsigned int initial_size
= 0);
425 ~wxDataViewIndexListModel();
428 Compare method that sorts the items by their index.
430 int Compare(const wxDataViewItem
& item1
,
431 const wxDataViewItem
& item2
,
432 unsigned int column
, bool ascending
);
435 Oberride this to indicate that the row has special font attributes.
436 This only affects the
437 wxDataViewTextRendererText() renderer.
438 See also wxDataViewItemAttr.
440 bool GetAttr(unsigned int row
, unsigned int col
,
441 wxDataViewItemAttr
& attr
);
444 Returns the wxDataViewItem at the given @e row.
446 wxDataViewItem
GetItem(unsigned int row
) const;
449 Returns the position of given @e item.
451 unsigned int GetRow(const wxDataViewItem
& item
) const;
454 Override this to allow getting values from the model.
456 void GetValue(wxVariant
& variant
, unsigned int row
,
457 unsigned int col
) const;
460 Call this after if the data has to be read again from
461 the model. This is useful after major changes when
462 calling the methods below (possibly thousands of times)
465 void Reset(unsigned int new_size
);
468 Call this after a row has been appended to the model.
473 Call this after a row has been changed.
475 void RowChanged(unsigned int row
);
478 Call this after a row has been deleted.
480 void RowDeleted(unsigned int row
);
483 Call this after a row has been inserted at the given position.
485 void RowInserted(unsigned int before
);
488 Call this after a row has been prepended to the model.
493 Call this after a value has been changed.
495 void RowValueChanged(unsigned int row
, unsigned int col
);
498 Call this after rows have been deleted. The array will internally
499 get copied and sorted in descending order so that the rows with
500 the highest position will be deleted first.
502 void RowsDeleted(const wxArrayInt
& rows
);
505 Called in order to set a value in the model.
507 bool SetValue(const wxVariant
& variant
, unsigned int row
,
514 @class wxDataViewVirtualListModel
515 @wxheader{dataview.h}
517 wxDataViewVirtualListModel is a specialized data model which lets
518 you address an item by its position (row) rather than its
519 wxDataViewItem and as such offers the exact same interface as
520 wxDataViewIndexListModel. The important difference is that under
521 platforms other than OS X, using this model will result in a
522 truely virtual control able to handle millions of items as the
523 control doesn't store any item (a feature not supported by the
524 Carbon API under OS X).
526 @see wxDataViewIndexListModel for the API.
531 class wxDataViewVirtualListModel
: public wxDataViewModel
537 wxDataViewVirtualListModel(unsigned int initial_size
= 0);
545 @class wxDataViewItemAttr
546 @wxheader{dataview.h}
548 This class is used to indicate to a wxDataViewCtrl
549 that a certain Item() has extra font attributes
550 for its renderer. For this, it is required to override
551 wxDataViewModel::GetAttr.
553 Attributes are currently only supported by
554 wxDataViewTextRendererText().
559 class wxDataViewItemAttr
565 wxDataViewItemAttr();
568 Call this to indicate that the item shall be displayed in bold text.
570 void SetBold(bool set
);
573 Call this to indicate that the item shall be displayed with
576 void SetColour(const wxColour
& colour
);
579 Call this to indicate that the item shall be displayed in italic text.
581 void SetItalic(bool set
);
587 @class wxDataViewItem
588 @wxheader{dataview.h}
590 wxDataViewItem is a small opaque class that represents an
591 item in a wxDataViewCtrl in a
592 persistent way, i.e. indepent of the position of the
593 item in the control or changes to its contents. It must
594 hold a unique ID of type @e void* in its only field
595 and can be converted to a from it.
597 If the ID is @e @NULL the wxDataViewItem is invalid and
598 wxDataViewItem::IsOk will return @e @false
599 which used in many places in the API of wxDataViewCtrl
600 to indicate that e.g. no item was found. An ID of @NULL
601 is also used to indicate the invisible root. Examples
603 wxDataViewModel::GetParent and
604 wxDataViewModel::GetChildren.
616 wxDataViewItem(void* id
= NULL
);
617 wxDataViewItem(const wxDataViewItem
& item
);
626 Returns @true if the ID is not @e @NULL.
634 @class wxDataViewCtrl
635 @wxheader{dataview.h}
637 wxDataViewCtrl is a control to display data either
638 in a tree like fashion or in a tabular form or both.
639 If you only need to display a simple tree structure
640 with an API more like the older wxTreeCtrl class,
641 then the specialized wxDataViewTreeCtrl
644 A wxDataViewItem is used
645 to represent a (visible) item in the control.
647 Unlike wxListCtrl wxDataViewCtrl doesn't
648 get its data from the user through virtual functions or by
649 setting it directly. Instead you need to write your own
650 wxDataViewModel and associate
651 it with this control. Then you need to add a number of
652 wxDataViewColumn to this control to
653 define what each column shall display. Each wxDataViewColumn
654 in turn owns 1 instance of a
655 wxDataViewRenderer to render its
656 cells. A number of standard renderers for rendering text, dates,
657 images, toggle, a progress bar etc. are provided. Additionally,
658 the user can write custom renderes deriving from
659 wxDataViewCustomRenderer
660 for displaying anything.
662 All data transfer from the control to the model and the user
663 code is done through wxVariant which can
664 be extended to support more data formats as necessary.
665 Accordingly, all type information uses the strings returned
666 from wxVariant::GetType.
670 Single selection mode. This is the default.
671 @style{wxDV_MULTIPLE}
672 Multiple selection mode.
673 @style{wxDV_ROW_LINES}
674 Use alternating colours for rows if supported by platform and theme.
675 @style{wxDV_HORIZ_RULES}
676 Display fine rules between row if supported.
677 @style{wxDV_VERT_RULES}
678 Display fine rules between columns is supported.

1084 @class wxDataViewRenderer
1085 @wxheader{dataview.h}
1087 This class is used by wxDataViewCtrl to render the individual cells.
1088 One instance of a renderer class is owned by a wxDataViewColumn. There
1089 is a number of ready-to-use renderers provided:
1090 wxDataViewTextRenderer,
1091 wxDataViewTextRendererAttr,
1092 wxDataViewIconTextRenderer,
1093 wxDataViewToggleRenderer,
1094 wxDataViewProgressRenderer,
1095 wxDataViewBitmapRenderer,
1096 wxDataViewDateRenderer.
1097 wxDataViewSpinRenderer.
1099 Additionally, the user can write own renderers by deriving from
1100 wxDataViewCustomRenderer.
1102 The @e wxDataViewCellMode flag controls, what actions
1103 the cell data allows. @e wxDATAVIEW_CELL_ACTIVATABLE
1104 indicates that the user can double click the cell and
1105 something will happen (e.g. a window for editing a date
1106 will pop up). @e wxDATAVIEW_CELL_EDITABLE indicates
1107 that the user can edit the data in-place, i.e. an control
1108 will show up after a slow click on the cell. This behaviour
1109 is best known from changing the filename in most file
1114 enum wxDataViewCellMode
1116 wxDATAVIEW_CELL_INERT,
1117 wxDATAVIEW_CELL_ACTIVATABLE,
1118 wxDATAVIEW_CELL_EDITABLE
1122 The @e wxDataViewCellRenderState flag controls how the
1123 the renderer should display its contents in a cell:
1126 enum wxDataViewCellRenderState
1128 wxDATAVIEW_CELL_SELECTED = 1,
1129 wxDATAVIEW_CELL_PRELIT = 2,
1130 wxDATAVIEW_CELL_INSENSITIVE = 4,
1131 wxDATAVIEW_CELL_FOCUSED = 8

1150 Returns the alignment. See SetAlignment()
1152 virtual int GetAlignment() const;
1155 Returns the cell mode.

1165 This methods retrieves the value from the renderer in order to
1166 transfer the value back to the data model. Returns @e @false
1169 virtual bool GetValue(wxVariant
& value
);
1172 Returns a string with the type of the wxVariant
1173 supported by this renderer.
1175 virtual wxString
GetVariantType();
1178 Sets the alignment of the renderer's content. The default value
1179 of wxDVR_DEFAULT_ALIGMENT indicates that the content should
1180 have the same alignment as the column header. The method is
1181 not implemented under OS X and the renderer always aligns its
1182 contents as the column header on that platform. The other platforms
1183 support both vertical and horizontal alignment.
1185 virtual void SetAlignment( int align
);
1187 Sets the owning wxDataViewColumn. This
1188 is usually called from within wxDataViewColumn.
1190 virtual void SetOwner(wxDataViewColumn
* owner
);
1193 Set the value of the renderer (and thus its cell) to @e value.
1194 The internal code will then render this cell with this data.
1196 virtual bool SetValue(const wxVariant
& value
);
1199 Before data is committed to the data model, it is passed to this
1200 method where it can be checked for validity. This can also be
1201 used for checking a valid range or limiting the user input in
1202 a certain aspect (e.g. max number of characters or only alphanumeric
1203 input, ASCII only etc.). Return @e @false if the value is
1205 Please note that due to implementation limitations, this validation
1206 is done after the editing control already is destroyed and the
1207 editing process finished.
1209 virtual bool Validate(wxVariant

1241 The wxDataViewIconTextRenderer class is used to display text with
1242 a small icon next to it as it is typically done in a file manager.
1243 This classes uses the wxDataViewIconText
1244 helper class to store its data. wxDataViewIonText can be converted
1245 to a from a wxVariant using the left shift

1383 @class wxDataViewCustomRenderer
1384 @wxheader{dataview.h}
1386 You need to derive a new class from wxDataViewCustomRenderer in
1387 order to write a new renderer. You need to override at least
1388 wxDataViewRenderer::SetValue,
1389 wxDataViewRenderer::GetValue,
1390 wxDataViewCustomRenderer::GetSize
1391 and wxDataViewCustomRenderer::Render.
1393 If you want your renderer to support in-place editing then you
1394 also need to override
1395 wxDataViewCustomRenderer::HasEditorCtrl,
1396 wxDataViewCustomRenderer::CreateEditorCtrl
1397 and wxDataViewCustomRenderer::GetValueFromEditorCtrl.
1398 Note that a special event handler will be pushed onto that
1399 editor control which handles ENTER and focus out events
1400 in order to end the editing.

1421 Override this to react to double clicks or ENTER. This method will
1422 only be called in wxDATAVIEW_CELL_ACTIVATABLE mode.
1424 virtual bool Activate( wxRect cell
,
1425 wxDataViewModel
* model
,
1426 const wxDataViewItem
& item
,
1430 Override this to create the actual editor control once editing
1431 is about to start. @a parent is the parent of the editor
1432 control, @a labelRect indicates the position and
1433 size of the editor control and @a value is its initial value:
1435 virtual wxControl
* CreateEditorCtrl(wxWindow

,
1437 const wxVariant
& value
);
1440 Create DC on request. Internal.
1442 virtual wxDC

1445 Return size required to show content.
1447 virtual wxSize

1450 Overrride this so that the renderer can get the value
1451 from the editor control (pointed to by @e editor):
1453 virtual bool GetValueFromEditorCtrl(wxControl
* editor
,
1457 Override this and make it return @e @true in order to
1458 indicate that this renderer supports in-place editing.
1460 virtual bool HasEditorCtrl();
1463 Overrride this to react to a left click. This method will
1464 only be called in wxDATAVIEW_CELL_ACTIVATABLE mode.
1466 virtual bool LeftClick( wxPoint cursor
,
1468 wxDataViewModel

,
1469 const wxDataViewItem

1473 Override this to render the cell. Before this is called,
1474 wxDataViewRenderer::SetValue was called
1475 so that this instance knows what to render.
1477 virtual bool Render(wxRect cell
, wxDC
* dc
, int state
);
1480 This method should be called from within Render()
1481 whenever you need to render simple text. This will ensure that the
1482 correct colour, font and vertical alignment will be chosen so the
1483 text will look the same as text drawn by native renderers.
1485 bool RenderText(const wxString

1632 Indicate that the column is sortable. This does
1633 not show any sorting indicate yet, but it does
1634 make the column header clickable. Call
1636 afterwards to actually make the sort indicator appear.
1637 If @a sortable is @false, the column header is
1638 no longer clickable and the sort indicator (little
