/////////////////////////////////////////////////////////////////////////////
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.
+
+ 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.
- 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.
+ 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
wxDataViewModel *musicModel = new MyMusicModel;
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
