## wxListCtrl

A list control presents lists in a number of formats: list view, report view, icon view and small icon view. In any case, elements are numbered from zero. For all these modes, the items are stored in the control and must be added to it using InsertItem method.

A special case of report view quite different from the other modes of the list control is a virtual control in which the items data (including text, images and attributes) is managed by the main program and is requested by the control itself only when needed which allows to have controls with millions of items without consuming much memory. To use virtual list control you must use SetItemCount first and overload at least OnGetItemText (and optionally OnGetItemImage and OnGetItemAttr) to return the information about the items when the control requests it. Virtual list control can be used as a normal one except that no operations which can take time proportional to the number of items in the control happen -- this is required to allow having a practically infinite number of items. For example, in a multiple selection virtual list control, the selections won't be sent when many items are selected at once because this could mean iterating over all the items.

Using many of wxListCtrl features is shown in the corresponding sample.

To intercept events from a list control, use the event table macros described in wxListEvent.

### wxListCtrl::~wxListCtrl

void ~wxListCtrl()

Destructor, destroying the list control.

### wxListCtrl::Arrange

Arranges the items in icon or small icon view. This only has effect on Win32. flag is one of:

wxLIST_ALIGN_DEFAULT | Default alignment.
wxLIST_ALIGN_LEFT | Align to the left side of the control.
wxLIST_ALIGN_TOP | Align to the top side of the control.
wxLIST_ALIGN_SNAP_TO_GRID | Snap to grid.

### wxListCtrl::AssignImageList

void AssignImageList(wxImageList* imageList, int which)

Sets the image list associated with the control and takes ownership of it (i.e. the control will, unlike when using SetImageList, delete the list when destroyed). which is one of wxIMAGE_LIST_NORMAL, wxIMAGE_LIST_SMALL, wxIMAGE_LIST_STATE (the last is unimplemented).

See also

wxListCtrl::SetImageList

### wxListCtrl::ClearAll

void ClearAll()

Creates the list control. See wxListCtrl::wxListCtrl for further details.

### wxListCtrl::DeleteAllItems

bool DeleteAllItems()

Deletes all the items in the list control.

NB: This function does not send the `wxEVT_COMMAND_LIST_DELETE_ITEM` event because deleting many items from the control would be too slow then (unlike DeleteItem).

### wxListCtrl::DeleteColumn

bool DeleteColumn(int col)

Deletes a column.

### wxListCtrl::DeleteItem

bool DeleteItem(long item)

Deletes the specified item. This function sends the `wxEVT_COMMAND_LIST_DELETE_ITEM` event for the item being deleted.

See also: DeleteAllItems

### wxListCtrl::EditLabel

void EditLabel(long item)

Starts editing the label of the given item. This function generates a EVT_LIST_BEGIN_LABEL_EDIT event which can be vetoed so that no text control will appear for in-place editing.

If the user changed the label (i.e. s/he does not press ESC or leave the text control without changes, a EVT_LIST_END_LABEL_EDIT event will be sent which can be vetoed as well.

### wxListCtrl::EnsureVisible

bool EnsureVisible(long item)

Ensures this item is visible.

### wxListCtrl::FindItem

long FindItem(long start, const wxString& str, const bool partial = FALSE)

Find an item whose label matches this string, starting from the item after start or the beginning if start is -1.

long FindItem(long start, const wxPoint& pt, int direction)

Find an item nearest this position in the specified direction, starting from the item after start or the beginning if start is -1.

wxPython note: In place of a single overloaded method name, wxPython implements the following methods:

FindItem(start, str, partial=FALSE) |

The base class version always returns `NULL`.

See also

OnGetItemImage,
OnGetItemText

### wxListCtrl::OnGetItemImage

virtual int OnGetItemImage(long item)

This function must be overloaded in the derived class for a control with `wxLC_VIRTUAL` style having an image list (if the control doesn't have an image list, it is not necessary to overload it). It should return the index of the items image in the controls image list or -1 for no image.

The base class version always returns -1.

See also

OnGetItemText,
OnGetItemAttr

### wxListCtrl::OnGetItemText

virtual wxString OnGetItemText(long item, long column)

This function must be overloaded in the derived class for a control with `wxLC_VIRTUAL` style. It should return the string containing the text of the given column for the specified `item`.

See also

SetItemCount,
OnGetItemImage,
OnGetItemAttr

### wxListCtrl::RefreshItem

void RefreshItem(long item)

Redraws the given item. This is only useful for the virtual list controls as without calling this function the displayed value of the item doesn't change even when the underlying data does change.

See also

RefreshItems

### wxListCtrl::RefreshItems

void RefreshItems(long itemFrom, long itemTo)

Redraws the items between itemFrom and itemTo. The starting item must be less than or equal to the ending one.

Just as RefreshItem this is only useful for virtual list controls.

### wxListCtrl::ScrollList

bool ScrollList(int dx, int dy)

Scrolls the list control. If in icon, small icon or report view mode, dx specifies the number of pixels to scroll. If in list view mode, dx specifies the number of columns to scroll. dy always specifies the number of pixels to scroll vertically.

NB: This method is currently only implemented in the Windows version.

### wxListCtrl::SetBackgroundColour

void SetBackgroundColour(const wxColour& col)

Sets the background colour (GetBackgroundColour already implicit in wxWindow class).

### wxListCtrl::SetColumn

bool SetColumn(int col, wxListItem& item)

Sets information about this column. See wxListCtrl::SetItem for more information.

### wxListCtrl::SetColumnWidth

bool SetColumnWidth(int col, int width)

Sets the column width.

width can be a width in pixels or wxLIST_AUTOSIZE (-1) or wxLIST_AUTOSIZE_USEHEADER (-2). wxLIST_AUTOSIZE will resize the column to the length of its longest item. wxLIST_AUTOSIZE_USEHEADER will resize the column to the length of the header (Win32) or 80 pixels (other platforms).

In small or normal icon view, col must be -1, and the column width is set for all columns.

### wxListCtrl::SetImageList

void SetImageList(wxImageList* imageList, int which)

Sets the image list associated with the control. which is one of wxIMAGE_LIST_NORMAL, wxIMAGE_LIST_SMALL, wxIMAGE_LIST_STATE (the last is unimplemented).

This method does not take ownership of the image list, you have to delete it yourself.

See also

wxListCtrl::AssignImageList

### wxListCtrl::SetItem

bool SetItem(wxListItem& info)

long SetItem(long index, int col, const wxString& label, int imageId = -1)

Sets information about the item.

wxListItem is a class with the following members:

long m_mask | Indicates which fields are valid. See the list of valid mask flags below.
long m_itemId | The zero-based item position.
int m_col | Zero-based column, if in report mode.
long m_state | The state of the item. See the list of valid state flags below.
long m_stateMask | A mask indicating which state flags are valid. See the list of valid state flags below.
wxString m_text | The label/header text.
int m_image | The zero-based index into an image list.
long m_data | Application-defined data.
int m_format | For columns only: the format. Can be wxLIST_FORMAT_LEFT, wxLIST_FORMAT_RIGHT or wxLIST_FORMAT_CENTRE.
int m_width | For columns only: the column width.

The m_mask member contains a bitlist specifying which of the other fields are valid. The flags are:

wxLIST_MASK_STATE | The m_state field is valid.
wxLIST_MASK_TEXT | The m_text field is valid.
wxLIST_MASK_IMAGE | The m_image field is valid.
wxLIST_MASK_DATA | The m_data field is valid.
wxLIST_MASK_WIDTH | The m_width field is valid.
wxLIST_MASK_FORMAT | The m_format field is valid.

The m_stateMask and m_state members take flags from the following:

The wxListItem object can also contain item-specific colour and font information: for this you need to call one of SetTextColour(), SetBackgroundColour() or SetFont() functions on it passing it the colour/font to use. If the colour/font is not specified, the default list control colour/font is used.

wxLIST_STATE_DONTCARE | Don't care what the state is. Win32 only.
wxLIST_STATE_DROPHILITED | The item is highlighted to receive a drop event. Win32 only.
wxLIST_STATE_FOCUSED | The item has the focus.
wxLIST_STATE_SELECTED | The item is selected.
wxLIST_STATE_CUT | The item is in the cut state. Win32 only.

long SetItem(long index, int col, const wxString& label, int imageId = -1)

Sets a string field at a particular column.

wxPython note: In place of a single overloaded method name, wxPython implements the following methods:

SetItem(item) | Sets information about the given wxListItem.
SetStringItem(index, col, label, imageId) | Sets a string or image at a given location.

### wxListCtrl::SetItemCount

void SetItemCount(long count)

This method can only be used with virtual list controls. It is used to indicate to the control the number of items it contains. After calling it, the main program should be ready to handle calls to various item callbacks (such as OnGetItemText) for all items in the range from 0 to count.

### wxListCtrl::SetItemData

bool SetItemData(long item, long data)

Associates application-defined data with this item.

### wxListCtrl::SetItemImage

bool SetItemImage(long item, int image, int selImage)

Sets the unselected and selected images associated with the item. The images are indices into the image list associated with the list control.

### wxListCtrl::SetItemPosition

bool SetItemPosition(long item, const wxPoint& pos)

Sets the position of the item, in icon or small icon view.

### wxListCtrl::SetItemState

bool SetItemState(long item, long state, long stateMask)

Sets the item state. For a list of state flags, see wxListCtrl::SetItem.

The stateMask indicates which state flags are valid.

### wxListCtrl::SetItemText

void SetItemText(long item, const wxString& text)

Sets the item text for this item.

### wxListCtrl::SetSingleStyle

void SetSingleStyle(long style, const bool add = TRUE)

Adds or removes a single window style.

### wxListCtrl::SetTextColour

void SetTextColour(const wxColour& col)

Sets the text colour of the list control.

### wxListCtrl::SetWindowStyleFlag

void SetWindowStyleFlag(long style)

Sets the whole window style.

### wxListCtrl::SortItems

bool SortItems(wxListCtrlCompare fnSortCallBack, long data)

Call this function to sort the items in the list control. Sorting is done using the specified fnSortCallBack function. This function must have the following prototype:

    int wxCALLBACK wxListCompareFunction(long item1, long item2, long sortData)

It is called each time when the two items must be compared and should return 0 if the items are equal, negative value if the first item is less than the second one and positive value if the first one is greater than the second one (the same convention as used by `qsort(3)`).

Parameters

item1

client data associated with the first item (NOT the index).

item2

client data associated with the second item (NOT the index).

data

the value passed to SortItems() itself.

Notice that the control may only be sorted on client data associated with the items, so you must use SetItemData if you want to be able to sort the items in the control.

Please see the listctrl sample for an example of using this function.

wxPython note: wxPython uses the sortData parameter to pass the Python function to call, so it is not available for programmer use. Call SortItems with a reference to a callable object that expects two parameters.

wxPerl note: In wxPerl the comparison function must take just two parameters; however, you may use a closure to achieve an effect similar to the SortItems third parameter.
