/////////////////////////////////////////////////////////////////////////////
wxDataViewModel::GetValue in order to define the data model which acts as an
interface between your actual data and the wxDataViewCtrl.
- Since you will usually also allow the wxDataViewCtrl to change your data
- through its graphical interface, you will also have to override
- wxDataViewModel::SetValue which the wxDataViewCtrl will call when a change
- to some data has been commited.
+ Note that wxDataViewModel does not define the position or index of any item
+ in the control because different controls might display the same data differently.
+ wxDataViewModel does provide a wxDataViewModel::Compare method which the
+ wxDataViewCtrl may use to sort the data either in conjunction with a column
+ header or without (see wxDataViewModel::HasDefaultCompare).
wxDataViewModel (as indeed the entire wxDataViewCtrl code) is using wxVariant
to store data and its type in a generic way. wxVariant can be extended to contain
- almost any data without changes to the original class.
+ almost any data without changes to the original class. To a certain extent,
+ you can use (the somewhat more elegant) wxAny instead of wxVariant as there
+ is code to convert between the two, but it is unclear what impact this will
+ have on performance.
- The data that is presented through this data model is expected to change at
- run-time. You need to inform the data model when a change happened.
+ Since you will usually allow the wxDataViewCtrl to change your data
+ through its graphical interface, you will also have to override
+ wxDataViewModel::SetValue which the wxDataViewCtrl will call when a change
+ to some data has been committed.
+
+ If the data represented by the model is changed by something else than its
+ associated wxDataViewCtrl, the control has to be notified about the change.
Depending on what happened you need to call one of the following methods:
- wxDataViewModel::ValueChanged,
- wxDataViewModel::ItemAdded,
- wxDataViewModel::ItemsDeleted,
- wxDataViewModel::ItemsChanged.
- Note that wxDataViewModel does not define the position or index of any item
- in the control because different controls might display the same data differently.
- wxDataViewModel does provide a wxDataViewModel::Compare method which the
- wxDataViewCtrl may use to sort the data either in conjunction with a column
- header or without (see wxDataViewModel::HasDefaultCompare).
-
This class maintains a list of wxDataViewModelNotifier which link this class
to the specific implementations on the supported platforms so that e.g. calling
wxDataViewModel::ValueChanged on this model will just call
wxDataViewIndexListModel, wxDataViewVirtualListModel, wxDataViewTreeStore,
wxDataViewListStore.
- Note that wxDataViewModel is reference counted, derives from wxObjectRefData
+ Note that wxDataViewModel is reference counted, derives from wxRefCounter
and cannot be deleted directly as it can be shared by several wxDataViewCtrls.
This implies that you need to decrease the reference count after
associating the model with a control like this:
@code
- wxDataViewCtrl *musicCtrl = new wxDataViewCtrl( this, ID_MUSIC_CTRL );
+ wxDataViewCtrl *musicCtrl = new wxDataViewCtrl( this, wxID_ANY );
wxDataViewModel *musicModel = new MyMusicModel;
- m_musicCtrl-AssociateModel( musicModel );
- musicModel-DecRef(); // avoid memory leak !!
+ m_musicCtrl->AssociateModel( musicModel );
+ musicModel->DecRef(); // avoid memory leak !!
+
+ // add columns now
+ @endcode
+
+ A potentially better way to avoid memory leaks is to use wxObjectDataPtr
+
+ @code
+ wxObjectDataPtr<MyMusicModel> musicModel;
+
+ wxDataViewCtrl *musicCtrl = new wxDataViewCtrl( this, wxID_ANY );
+ musicModel = new MyMusicModel;
+ m_musicCtrl->AssociateModel( musicModel.get() );
+
// add columns now
@endcode
