Inheritance diagram for wxItemContainerImmutable:

Detailed Description

wxItemContainer defines an interface which is implemented by all controls which have string subitems each of which may be selected.

It is decomposed in wxItemContainerImmutable which omits all methods adding/removing items and is used by wxRadioBox and wxItemContainer itself.

Note that this is not a control, it's a mixin interface that classes have to derive from in addition to wxControl or wxWindow.

Examples: wxListBox, wxCheckListBox, wxChoice and wxComboBox (which implements an extended interface deriving from this one)

Library: wxCore

Category: Controls

See Also: wxControlWithItems, wxItemContainer

	wxItemContainerImmutable ()
	Constructor.


virtual unsigned int	GetCount () const =0
	Returns the number of items in the control.

bool	IsEmpty () const
	Returns true if the control is empty or false if it has some items.

virtual wxString	GetString (unsigned int n) const =0
	Returns the label of the item with the given index.

	Returns the array of the labels of all items in the control.

	Sets the label for the given item.

virtual int	FindString (const wxString &string, bool caseSensitive=false) const
	Finds an item whose label matches the given string.

Selection
virtual void	SetSelection (int n)=0
	Sets the selection to the given item n or removes the selection entirely if n == `wxNOT_FOUND`.

virtual int	GetSelection () const =0
	Returns the index of the selected item or `wxNOT_FOUND` if no item is selected.

bool	SetStringSelection (const wxString &string)
	Selects the item with the specified string in the control.

virtual wxString	GetStringSelection () const
	Returns the label of the selected item or an empty string if no item is selected.

void	Select (int n)
	This is the same as SetSelection() and exists only because it is slightly more natural for controls which support multiple selection.

virtual int wxItemContainerImmutable::FindString	(	const wxString &	string,
		bool	caseSensitive = `false`
	)		const

virtual

Finds an item whose label matches the given string.

Parameters

string	String to find.
caseSensitive	Whether search is case sensitive (default is not).

Returns: The zero-based position of the item, or wxNOT_FOUND if the string was not found.

Reimplemented in wxListBox, wxComboBox, wxRadioBox, and wxChoice.

virtual unsigned int wxItemContainerImmutable::GetCount ( ) const

pure virtual

Returns the number of items in the control.

See Also: IsEmpty()

Implemented in wxRadioBox, wxComboBox, wxListBox, and wxChoice.

virtual int wxItemContainerImmutable::GetSelection ( ) const

pure virtual

Returns the index of the selected item or wxNOT_FOUND if no item is selected.

Returns: The position of the current selection.

Remarks: This method can be used with single selection list boxes only, you should use wxListBox::GetSelections() for the list boxes with wxLB_MULTIPLE style.

See Also: SetSelection(), GetStringSelection()

Implemented in wxRadioBox, wxComboBox, wxListBox, and wxChoice.

virtual wxString wxItemContainerImmutable::GetString ( unsigned int n ) const

pure virtual

Returns the label of the item with the given index.

Parameters

n	The zero-based index.

Returns: The label of the item or an empty string if the position was invalid.

Implemented in wxRadioBox, wxListBox, wxComboBox, and wxChoice.

wxArrayString wxItemContainerImmutable::GetStrings ( ) const

Returns the array of the labels of all items in the control.

virtual wxString wxItemContainerImmutable::GetStringSelection ( ) const

virtual

Returns the label of the selected item or an empty string if no item is selected.

See Also: GetSelection()

Reimplemented in wxComboBox.

bool wxItemContainerImmutable::IsEmpty ( ) const

Returns true if the control is empty or false if it has some items.

See Also: GetCount()

void wxItemContainerImmutable::Select ( int n )

This is the same as SetSelection() and exists only because it is slightly more natural for controls which support multiple selection.

virtual void wxItemContainerImmutable::SetSelection ( int n )

pure virtual

Sets the selection to the given item n or removes the selection entirely if n == wxNOT_FOUND.

Note that this does not cause any command events to be emitted nor does it deselect any other items in the controls which support multiple selections.

Parameters

n	The string position to select, starting from zero.

See Also: SetString(), SetStringSelection()

Implemented in wxComboBox, wxRadioBox, wxChoice, and wxListBox.

virtual void wxItemContainerImmutable::SetString	(	unsigned int	n,
		const wxString &	string
	)

pure virtual

Sets the label for the given item.

Parameters

n	The zero-based item index.
string	The label to set.

Implemented in wxRadioBox, wxListBox, wxComboBox, and wxChoice.

bool wxItemContainerImmutable::SetStringSelection ( const wxString & string )

Selects the item with the specified string in the control.

This method doesn't cause any command events to be emitted.

Notice that this method is case-insensitive, i.e. the string is compared with all the elements of the control case-insensitively and the first matching entry is selected, even if it doesn't have exactly the same case as this string and there is an exact match afterwards.

Parameters

string The string to select.

Returns: true if the specified string has been selected, false if it wasn't found in the control.
