11 @class wxDataViewModel
13 wxDataViewModel is the base class for all data model to be displayed by a
16 All other models derive from it and must implement its pure virtual functions
17 in order to define a complete data model. In detail, you need to override
18 wxDataViewModel::IsContainer, wxDataViewModel::GetParent, wxDataViewModel::GetChildren,
19 wxDataViewModel::GetColumnCount, wxDataViewModel::GetColumnType and
20 wxDataViewModel::GetValue in order to define the data model which acts as an
21 interface between your actual data and the wxDataViewCtrl.
23 Since you will usually also allow the wxDataViewCtrl to change your data
24 through its graphical interface, you will also have to override
25 wxDataViewModel::SetValue which the wxDataViewCtrl will call when a change
26 to some data has been commited.
28 wxDataViewModel (as indeed the entire wxDataViewCtrl code) is using wxVariant
29 to store data and its type in a generic way. wxVariant can be extended to contain
30 almost any data without changes to the original class.
32 The data that is presented through this data model is expected to change at
33 run-time. You need to inform the data model when a change happened.
34 Depending on what happened you need to call one of the following methods:
35 - wxDataViewModel::ValueChanged,
36 - wxDataViewModel::ItemAdded,
37 - wxDataViewModel::ItemDeleted,
38 - wxDataViewModel::ItemChanged,
39 - wxDataViewModel::Cleared.
41 There are plural forms for notification of addition, change or removal of
42 several item at once. See:
43 - wxDataViewModel::ItemsAdded,
44 - wxDataViewModel::ItemsDeleted,
45 - wxDataViewModel::ItemsChanged.
47 Note that wxDataViewModel does not define the position or index of any item
48 in the control because different controls might display the same data differently.
49 wxDataViewModel does provide a wxDataViewModel::Compare method which the
50 wxDataViewCtrl may use to sort the data either in conjunction with a column
51 header or without (see wxDataViewModel::HasDefaultCompare).
53 This class maintains a list of wxDataViewModelNotifier which link this class
54 to the specific implementations on the supported platforms so that e.g. calling
55 wxDataViewModel::ValueChanged on this model will just call
56 wxDataViewModelNotifier::ValueChanged for each notifier that has been added.
57 You can also add your own notifier in order to get informed about any changes
58 to the data in the list model.
60 Currently wxWidgets provides the following models apart from the base model:
61 wxDataViewIndexListModel, wxDataViewVirtualListModel, wxDataViewTreeStore,
64 Note that wxDataViewModel is reference counted, derives from wxObjectRefData
65 and cannot be deleted directly as it can be shared by several wxDataViewCtrls.
66 This implies that you need to decrease the reference count after
67 associating the model with a control like this:
70 wxDataViewCtrl *musicCtrl = new wxDataViewCtrl( this, ID_MUSIC_CTRL );
71 wxDataViewModel *musicModel = new MyMusicModel;
72 m_musicCtrl-AssociateModel( musicModel );
73 musicModel-DecRef(); // avoid memory leak !!
81 class wxDataViewModel
: public wxObjectRefData
90 Adds a wxDataViewModelNotifier to the model.
92 void AddNotifier(wxDataViewModelNotifier
* notifier
);
95 Called to inform the model that all data has been cleared.
96 The control will reread the data from the model again.
98 virtual bool Cleared();
101 The compare function to be used by control. The default compare function
102 sorts by container and other items separately and in ascending order.
103 Override this for a different sorting behaviour.
105 @see HasDefaultCompare().
107 virtual int Compare(const wxDataViewItem
& item1
,
108 const wxDataViewItem
& item2
,
113 Override this to indicate that the item has special font attributes.
114 This only affects the wxDataViewTextRendererText renderer.
116 @see wxDataViewItemAttr.
118 virtual bool GetAttr(const wxDataViewItem
& item
, unsigned int col
,
119 wxDataViewItemAttr
& attr
);
122 Override this so the control can query the child items of an item.
123 Returns the number of items.
125 virtual unsigned int GetChildren(const wxDataViewItem
& item
,
126 wxDataViewItemArray
& children
) const = 0;
129 Override this to indicate the number of columns in the model.
131 virtual unsigned int GetColumnCount() const = 0;
134 Override this to indicate what type of data is stored in the
135 column specified by @a col.
137 This should return a string indicating the type of data as reported by wxVariant.
139 virtual wxString
GetColumnType(unsigned int col
) const = 0;
142 Override this to indicate which wxDataViewItem representing the parent
143 of @a item or an invalid wxDataViewItem if the the root item is
146 virtual wxDataViewItem
GetParent(const wxDataViewItem
& item
) const = 0;
149 Override this to indicate the value of @a item.
150 A wxVariant is used to store the data.
152 virtual void GetValue(wxVariant
& variant
, const wxDataViewItem
& item
,
153 unsigned int col
) const = 0;
156 Override this method to indicate if a container item merely acts as a
157 headline (or for categorisation) or if it also acts a normal item with
158 entries for futher columns. By default returns @false.
160 virtual bool HasContainerColumns(const wxDataViewItem
& item
) const;
163 Override this to indicate that the model provides a default compare
164 function that the control should use if no wxDataViewColumn has been
165 chosen for sorting. Usually, the user clicks on a column header for
166 sorting, the data will be sorted alphanumerically.
168 If any other order (e.g. by index or order of appearance) is required,
169 then this should be used.
170 See wxDataViewIndexListModel for a model which makes use of this.
172 virtual bool HasDefaultCompare() const;
175 Override this to indicate of @a item is a container, i.e. if
176 it can have child items.
178 virtual bool IsContainer(const wxDataViewItem
& item
) const = 0;
181 Call this to inform the model that an item has been added to the data.
183 virtual bool ItemAdded(const wxDataViewItem
& parent
,
184 const wxDataViewItem
& item
);
187 Call this to inform the model that an item has changed.
189 This will eventually emit a wxEVT_DATAVIEW_ITEM_VALUE_CHANGED
190 event (in which the column fields will not be set) to the user.
192 virtual bool ItemChanged(const wxDataViewItem
& item
);
195 Call this to inform the model that an item has been deleted from the data.
197 virtual bool ItemDeleted(const wxDataViewItem
& parent
,
198 const wxDataViewItem
& item
);
201 Call this to inform the model that several items have been added to the data.
203 virtual bool ItemsAdded(const wxDataViewItem
& parent
,
204 const wxDataViewItemArray
& items
);
207 Call this to inform the model that several items have changed.
209 This will eventually emit wxEVT_DATAVIEW_ITEM_VALUE_CHANGED
210 events (in which the column fields will not be set) to the user.
212 virtual bool ItemsChanged(const wxDataViewItemArray
& items
);
215 Call this to inform the model that several items have been deleted.
217 virtual bool ItemsDeleted(const wxDataViewItem
& parent
,
218 const wxDataViewItemArray
& items
);
221 Remove the @a notifier from the list of notifiers.
223 void RemoveNotifier(wxDataViewModelNotifier
* notifier
);
226 Call this to initiate a resort after the sort function has been changed.
228 virtual void Resort();
231 This gets called in order to set a value in the data model.
232 The most common scenario is that the wxDataViewCtrl calls this method
233 after the user changed some data in the view.
235 Afterwards ValueChanged() has to be called!
237 virtual bool SetValue(const wxVariant
& variant
, const wxDataViewItem
& item
,
238 unsigned int col
) = 0;
241 Call this to inform this model that a value in the model has been changed.
242 This is also called from wxDataViewCtrl's internal editing code, e.g. when
243 editing a text field in the control.
245 This will eventually emit a wxEVT_DATAVIEW_ITEM_VALUE_CHANGED
248 virtual bool ValueChanged(const wxDataViewItem
& item
,
254 Destructor. This should not be called directly. Use DecRef() instead.
256 virtual ~wxDataViewModel();
262 @class wxDataViewIndexListModel
264 wxDataViewIndexListModel is a specialized data model which lets you address
265 an item by its position (row) rather than its wxDataViewItem (which you can
266 obtain from this class).
267 This model also provides its own wxDataViewIndexListModel::Compare
268 method which sorts the model's data by the index.
270 This model is not a virtual model since the control stores each wxDataViewItem.
271 Use wxDataViewVirtualListModel if you need to display millions of items or
272 have other reason to use a virtual control.
277 class wxDataViewIndexListModel
: public wxDataViewModel
283 wxDataViewIndexListModel(unsigned int initial_size
= 0);
288 virtual ~wxDataViewIndexListModel();
291 Compare method that sorts the items by their index.
293 int Compare(const wxDataViewItem
& item1
,
294 const wxDataViewItem
& item2
,
295 unsigned int column
, bool ascending
);
298 Override this to indicate that the row has special font attributes.
299 This only affects the wxDataViewTextRendererText() renderer.
301 @see wxDataViewItemAttr.
303 virtual bool GetAttrByRow(unsigned int row
, unsigned int col
,
304 wxDataViewItemAttr
& attr
);
307 Returns the wxDataViewItem at the given @e row.
309 wxDataViewItem
GetItem(unsigned int row
) const;
312 Returns the position of given @e item.
314 unsigned int GetRow(const wxDataViewItem
& item
) const;
317 Override this to allow getting values from the model.
319 virtual void GetValueByRow(wxVariant
& variant
, unsigned int row
,
320 unsigned int col
) const = 0;
323 Call this after if the data has to be read again from the model.
324 This is useful after major changes when calling the methods below
325 (possibly thousands of times) doesn't make sense.
327 void Reset(unsigned int new_size
);
330 Call this after a row has been appended to the model.
335 Call this after a row has been changed.
337 void RowChanged(unsigned int row
);
340 Call this after a row has been deleted.
342 void RowDeleted(unsigned int row
);
345 Call this after a row has been inserted at the given position.
347 void RowInserted(unsigned int before
);
350 Call this after a row has been prepended to the model.
355 Call this after a value has been changed.
357 void RowValueChanged(unsigned int row
, unsigned int col
);
360 Call this after rows have been deleted.
361 The array will internally get copied and sorted in descending order so
362 that the rows with the highest position will be deleted first.
364 void RowsDeleted(const wxArrayInt
& rows
);
367 Called in order to set a value in the model.
369 virtual bool SetValueByRow(const wxVariant
& variant
, unsigned int row
,
370 unsigned int col
) = 0;
376 @class wxDataViewVirtualListModel
378 wxDataViewVirtualListModel is a specialized data model which lets you address
379 an item by its position (row) rather than its wxDataViewItem and as such offers
380 the exact same interface as wxDataViewIndexListModel.
381 The important difference is that under platforms other than OS X, using this
382 model will result in a truly virtual control able to handle millions of items
383 as the control doesn't store any item (a feature not supported by the
384 Carbon API under OS X).
386 @see wxDataViewIndexListModel for the API.
391 class wxDataViewVirtualListModel
: public wxDataViewModel
397 wxDataViewVirtualListModel(unsigned int initial_size
= 0);
403 @class wxDataViewItemAttr
405 This class is used to indicate to a wxDataViewCtrl that a certain item
406 (see wxDataViewItem) has extra font attributes for its renderer.
407 For this, it is required to override wxDataViewModel::GetAttr.
409 Attributes are currently only supported by wxDataViewTextRendererText.
414 class wxDataViewItemAttr
420 wxDataViewItemAttr();
423 Call this to indicate that the item shall be displayed in bold text.
425 void SetBold(bool set
);
428 Call this to indicate that the item shall be displayed with that colour.
430 void SetColour(const wxColour
& colour
);
433 Call this to indicate that the item shall be displayed in italic text.
435 void SetItalic(bool set
);
441 @class wxDataViewItem
443 wxDataViewItem is a small opaque class that represents an item in a wxDataViewCtrl
444 in a persistent way, i.e. indepent of the position of the item in the control
445 or changes to its contents.
447 It must hold a unique ID of type @e void* in its only field and can be converted
450 If the ID is @NULL the wxDataViewItem is invalid and wxDataViewItem::IsOk will
451 return @false which used in many places in the API of wxDataViewCtrl to
452 indicate that e.g. no item was found. An ID of @NULL is also used to indicate
453 the invisible root. Examples for this are wxDataViewModel::GetParent and
454 wxDataViewModel::GetChildren.
466 wxDataViewItem(void* id
= NULL
);
467 wxDataViewItem(const wxDataViewItem
& item
);
476 Returns @true if the ID is not @NULL.
484 @class wxDataViewCtrl
486 wxDataViewCtrl is a control to display data either in a tree like fashion or
487 in a tabular form or both.
489 If you only need to display a simple tree structure with an API more like the
490 older wxTreeCtrl class, then the specialized wxDataViewTreeCtrl can be used.
491 Likewise, if you only want to display simple table structure you can use
492 the specialized wxDataViewListCtrl class. Both wxDataViewTreeCtrl and
493 wxDataViewListCtrl can be used without defining your own wxDataViewModel.
495 A wxDataViewItem is used to represent a (visible) item in the control.
497 Unlike wxListCtrl, wxDataViewCtrl doesn't get its data from the user through
498 virtual functions or by setting it directly. Instead you need to write your own
499 wxDataViewModel and associate it with this control.
500 Then you need to add a number of wxDataViewColumn to this control to define
501 what each column shall display. Each wxDataViewColumn in turn owns 1 instance
502 of a wxDataViewRenderer to render its cells.
504 A number of standard renderers for rendering text, dates, images, toggle,
505 a progress bar etc. are provided. Additionally, the user can write custom
506 renderers deriving from wxDataViewCustomRenderer for displaying anything.
508 All data transfer from the control to the model and the user code is done
509 through wxVariant which can be extended to support more data formats as necessary.
510 Accordingly, all type information uses the strings returned from wxVariant::GetType.
514 Single selection mode. This is the default.
515 @style{wxDV_MULTIPLE}
516 Multiple selection mode.
517 @style{wxDV_ROW_LINES}
518 Use alternating colours for rows if supported by platform and theme.
519 @style{wxDV_HORIZ_RULES}
520 Display fine rules between row if supported.
521 @style{wxDV_VERT_RULES}
522 Display fine rules between columns is supported.
523 @style{wxDV_VARIABLE_LINE_HEIGHT}
524 Allow variable line heights.
525 This can be inefficient when displaying large number of items.

1012 @class wxDataViewRenderer
1014 This class is used by wxDataViewCtrl to render the individual cells.
1015 One instance of a renderer class is owned by a wxDataViewColumn.
1016 There is a number of ready-to-use renderers provided:
1017 - wxDataViewTextRenderer,
1018 - wxDataViewTextRendererAttr,
1019 - wxDataViewIconTextRenderer,
1020 - wxDataViewToggleRenderer,
1021 - wxDataViewProgressRenderer,
1022 - wxDataViewBitmapRenderer,
1023 - wxDataViewDateRenderer,
1024 - wxDataViewSpinRenderer.
1026 Additionally, the user can write own renderers by deriving from
1027 wxDataViewCustomRenderer.
1029 The ::wxDataViewCellMode and ::wxDataViewCellRenderState flags accepted
1030 by the constructors respectively controls what actions the cell data allows
1031 and how the renderer should display its contents in a cell.
1036 class wxDataViewRenderer
: public wxObject
1042 wxDataViewRenderer(const wxString
& varianttype
,
1043 wxDataViewCellMode mode

1047 Returns the alignment. See SetAlignment()
1049 virtual int GetAlignment() const;
1052 Returns the cell mode.
1054 virtual wxDataViewCellMode
GetMode() const;
1057 Returns pointer to the owning wxDataViewColumn.
1059 wxDataViewColumn
* GetOwner() const;
1062 This methods retrieves the value from the renderer in order to
1063 transfer the value back to the data model.
1065 Returns @false on failure.
1067 virtual bool GetValue(wxVariant

) const = 0;
1070 Returns a string with the type of the wxVariant supported by this renderer.
1072 wxString
GetVariantType() const;
1075 Sets the alignment of the renderer's content.
1076 The default value of @c wxDVR_DEFAULT_ALIGMENT indicates that the content
1077 should have the same alignment as the column header.
1079 The method is not implemented under OS X and the renderer always aligns
1080 its contents as the column header on that platform. The other platforms
1081 support both vertical and horizontal alignment.
1083 virtual void SetAlignment( int align
);
1085 Sets the owning wxDataViewColumn.
1086 This is usually called from within wxDataViewColumn.
1088 void SetOwner(wxDataViewColumn
* owner
);
1091 Set the value of the renderer (and thus its cell) to @a value.
1092 The internal code will then render this cell with this data.
1094 virtual bool SetValue(const wxVariant
& value
) = 0;
1097 Before data is committed to the data model, it is passed to this
1098 method where it can be checked for validity. This can also be
1099 used for checking a valid range or limiting the user input in
1100 a certain aspect (e.g. max number of characters or only alphanumeric
1101 input, ASCII only etc.). Return @false if the value is not valid.
1103 Please note that due to implementation limitations, this validation
1104 is done after the editing control already is destroyed and the
1105 editing process finished.
1107 virtual bool Validate(wxVariant
& value
);
1113 @class wxDataViewTextRenderer
1115 wxDataViewTextRenderer is used for rendering text.

1137 The wxDataViewIconTextRenderer class is used to display text with
1138 a small icon next to it as it is typically done in a file manager.
1140 This classes uses the wxDataViewIconText helper class to store its data.
1141 wxDataViewIonText can be converted to and from a wxVariant using the left shift

1183 @class wxDataViewSpinRenderer
1185 This is a specialized renderer for rendering integer values.
1186 It supports modifying the values in-place by using a wxSpinCtrl.
1187 The renderer only support variants of type @e long.
1192 class wxDataViewSpinRenderer

);
1273 @class wxDataViewCustomRenderer
1275 You need to derive a new class from wxDataViewCustomRenderer in
1276 order to write a new renderer.
1278 You need to override at least wxDataViewRenderer::SetValue, wxDataViewRenderer::GetValue,
1279 wxDataViewCustomRenderer::GetSize and wxDataViewCustomRenderer::Render.
1281 If you want your renderer to support in-place editing then you also need to override
1282 wxDataViewCustomRenderer::HasEditorCtrl, wxDataViewCustomRenderer::CreateEditorCtrl
1283 and wxDataViewCustomRenderer::GetValueFromEditorCtrl.
1285 Note that a special event handler will be pushed onto that editor control
1286 which handles @e \<ENTER\> and focus out events in order to end the editing.

1316 Override this to create the actual editor control once editing
1319 @a parent is the parent of the editor control, @a labelRect indicates the
1320 position and size of the editor control and @a value is its initial value:
1324 return new wxSpinCtrl( parent, wxID_ANY, wxEmptyString,
1325 labelRect.GetTopLeft(), labelRect.GetSize(), 0, 0, 100, l );
1329 virtual wxControl

,
1359 Override this and make it return @true in order to
1360 indicate that this renderer supports in-place editing.
1362 virtual bool HasEditorCtrl();
1365 Overrride this to react to a left click.
1366 This method will only be called in @c wxDATAVIEW_CELL_ACTIVATABLE mode.

1382 This method should be called from within Render() whenever you need to
1384 This will ensure that the correct colour, font and vertical alignment will
1385 be chosen so the text will look the same as text drawn by native renderers.

1883 @class wxDataViewListStore
1885 wxDataViewListStore is a specialised wxDataViewModel for storing
1886 a simple table of data. Since it derives from wxDataViewIndexListModel
1887 its data is be accessed by row (i.e. by index) instead of only
1890 This class actually stores the values (therefore its name)
1891 and implements all virtual methods from the base classes so it can be
1892 used directly without having to derive any class from it, but it is
1893 mostly used from within wxDataViewListCtrl.
1899 class wxDataViewListStore
