Constructor & Destructor Documentation

virtual wxDataViewListModel::~wxDataViewListModel ( )

virtual

Destructor.

Member Function Documentation

int wxDataViewListModel::Compare	(	const wxDataViewItem &	item1,
		const wxDataViewItem &	item2,
		unsigned int	column,
		bool	ascending
	)		const

virtual

Compare method that sorts the items by their index.

Reimplemented from wxDataViewModel.

virtual bool wxDataViewListModel::GetAttrByRow	(	unsigned int	row,
		unsigned int	col,
		wxDataViewItemAttr &	attr
	)		const

virtual

Override this to indicate that the row has special font attributes.

This only affects the wxDataViewTextRendererText() renderer.

The base class version always simply returns false.

See also: wxDataViewItemAttr.

Parameters

row	The row for which the attribute is requested.
col	The column for which the attribute is requested.
attr	The attribute to be filled in if the function returns true.

Returns: true if this item has an attribute or false otherwise.

unsigned int wxDataViewListModel::GetCount ( ) const

pure virtual

Returns the number of items (or rows) in the list.

unsigned int wxDataViewListModel::GetRow ( const wxDataViewItem & item ) const

pure virtual

Returns the position of given item.

virtual void wxDataViewListModel::GetValueByRow	(	wxVariant &	variant,
		unsigned int	row,
		unsigned int	col
	)		const

pure virtual

Override this to allow getting values from the model.

Implemented in wxDataViewListStore.

virtual bool wxDataViewListModel::IsEnabledByRow	(	unsigned int	row,
		unsigned int	col
	)		const

virtual

Override this if you want to disable specific items.

The base class version always returns true, thus making all items enabled by default.

Parameters

row	The row of the item whose enabled status is requested.
col	The column of the item whose enabled status is requested.

Returns: true if the item at this row and column should be enabled, false otherwise.

Note: See wxDataViewModel::IsEnabled() for the current status of support for disabling the items under different platforms.

Since: 2.9.2

virtual bool wxDataViewListModel::SetValueByRow	(	const wxVariant &	variant,
		unsigned int	row,
		unsigned int	col
	)

pure virtual

Called in order to set a value in the model.

Implemented in wxDataViewListStore.
