Detail
The TreeViewColumn object represents a visible column in a TreeView widget. It allows to set properties of the column header, and functions as a holding pen for the cell renderers which determine how the data in the column is displayed.

Methods
treeViewColumnPackStart :: CellRendererClass cell => TreeViewColumn -> cell -> Bool -> IO ()

Add a cell renderer at the beginning of a column.

  • Excess space is divided equally among all renderers which have expand set to True.
treeViewColumnPackEnd :: CellRendererClass cell => TreeViewColumn -> cell -> Bool -> IO ()

Add a cell renderer at the end of a column.

  • Excess space is divided equally among all renderers which have expand set to True.
treeViewColumnClear :: TreeViewColumn -> IO ()
Remove the associations of attributes to a store for all CellRenderers.
treeViewColumnGetCellRenderers :: TreeViewColumn -> IO [CellRenderer]
Retrieve all CellRenderers that are contained in this column.
treeViewColumnSetSpacing :: TreeViewColumn -> Int -> IO ()
Set the number of pixels between two cell renderers.
treeViewColumnGetSpacing :: TreeViewColumn -> IO Int
Get the number of pixels between two cell renderers.
treeViewColumnSetVisible :: TreeViewColumn -> Bool -> IO ()
Set the visibility of a given column.
treeViewColumnGetVisible :: TreeViewColumn -> IO Bool
Get the visibility of a given column.
treeViewColumnSetResizable :: TreeViewColumn -> Bool -> IO ()
Set if a given column is resizable by the user.
treeViewColumnGetResizable :: TreeViewColumn -> IO Bool
Get if a given column is resizable by the user.
data TreeViewColumnSizing
Wether columns of a tree or list widget can be resized.

show/hide Instances
treeViewColumnSetSizing :: TreeViewColumn -> TreeViewColumnSizing -> IO ()
Set wether the column can be resized.
treeViewColumnGetSizing :: TreeViewColumn -> IO TreeViewColumnSizing
Return the resizing type of the column.
treeViewColumnGetWidth :: TreeViewColumn -> IO Int
Query the current width of the column.
treeViewColumnSetFixedWidth :: TreeViewColumn -> Int -> IO ()

Set the width of the column.

treeViewColumnGetFixedWidth :: TreeViewColumn -> IO Int

Gets the fixed width of the column.

  • This is meaningful only if the sizing type is TreeViewColumnFixed.
  • This value is only meaning may not be the actual width of the column on the screen, just what is requested.
treeViewColumnSetMinWidth :: TreeViewColumn -> Int -> IO ()
Set minimum width of the column.
treeViewColumnGetMinWidth :: TreeViewColumn -> IO Int
Get the minimum width of a column. Returns -1 if this width was not set.
treeViewColumnSetMaxWidth :: TreeViewColumn -> Int -> IO ()
Set maximum width of the column.
treeViewColumnGetMaxWidth :: TreeViewColumn -> IO Int
Get the maximum width of a column. Returns -1 if this width was not set.
treeViewColumnClicked :: TreeViewColumn -> IO ()
Emit the clicked signal on the column.
treeViewColumnSetTitle :: TreeViewColumn -> String -> IO ()
Set the widget's title if a custom widget has not been set.
treeViewColumnGetTitle :: TreeViewColumn -> IO (Maybe String)
Get the widget's title.
treeViewColumnSetClickable :: TreeViewColumn -> Bool -> IO ()
Set if the column should be sensitive to mouse clicks.
treeViewColumnGetClickable :: TreeViewColumn -> IO Bool
Returns True if the user can click on the header for the column.
treeViewColumnSetWidget :: WidgetClass widget => TreeViewColumn -> widget -> IO ()
Set the column's title to this widget.
treeViewColumnGetWidget :: TreeViewColumn -> IO Widget
Retrieve the widget responsible for showing the column title. In case only a text title was set this will be a Alignment widget with a Label inside.
treeViewColumnSetAlignment
:: TreeViewColumn
-> Floatxalign - The alignment, which is between [0.0 and 1.0] inclusive.
-> IO ()
Sets the alignment of the title or custom widget inside the column header. The alignment determines its location inside the button -- 0.0 for left, 0.5 for center, 1.0 for right.
treeViewColumnGetAlignment :: TreeViewColumn -> IO Float
Returns the current x alignment of the tree column. This value can range between 0.0 and 1.0.
treeViewColumnSetReorderable :: TreeViewColumn -> Bool -> IO ()
Set if the column can be reordered by the end user dragging the header.
treeViewColumnGetReorderable :: TreeViewColumn -> IO Bool
Returns whether the column can be reordered by the user.
treeViewColumnSetSortColumnId :: TreeViewColumn -> SortColumnId -> IO ()

Set the column by which to sort.

  • Sets the logical columnId that this column sorts on when this column is selected for sorting. The selected column's header will be clickable after this call. Logical refers to the SortColumnId for which a comparison function was set.
treeViewColumnGetSortColumnId :: TreeViewColumn -> IO SortColumnId

Get the column by which to sort.

treeViewColumnSetSortIndicator :: TreeViewColumn -> Bool -> IO ()
Set if a given column has sorting arrows in its heading.
treeViewColumnGetSortIndicator :: TreeViewColumn -> IO Bool
Query if a given column has sorting arrows in its heading.
treeViewColumnSetSortOrder :: TreeViewColumn -> SortType -> IO ()

Set if a given column is sorted in ascending or descending order.

treeViewColumnGetSortOrder :: TreeViewColumn -> IO SortType
Query if a given column is sorted in ascending or descending order.

treeViewColumnSetExpand
:: TreeViewColumn
-> Boolexpand - True if the column should take available extra space, False if not
-> IO ()

Sets the column to take available extra space. This space is shared equally amongst all columns that have the expand set to True. If no column has this option set, then the last column gets all extra space. By default, every column is created with this False.

  • Available since Gtk+ version 2.4
treeViewColumnGetExpand
:: TreeViewColumn
-> IO Boolreturns True, if the column expands

Return True if the column expands to take any available space.

  • Available since Gtk+ version 2.4
treeViewColumnCellIsVisible
:: TreeViewColumn
-> IO Boolreturns True, if any of the cells packed into the treeColumn are currently visible
Returns True if any of the cells packed into the treeColumn are visible. For this to be meaningful, you must first initialize the cells with treeViewColumnCellSetCellData
treeViewColumnFocusCell
:: CellRendererClass cell
=> TreeViewColumn
-> cellcell - A CellRenderer
-> IO ()

Sets the current keyboard focus to be at cell, if the column contains 2 or more editable and activatable cells.

  • Available since Gtk+ version 2.2
treeViewColumnQueueResize :: TreeViewColumn -> IO ()

Flags the column, and the cell renderers added to this column, to have their sizes renegotiated.

  • Available since Gtk+ version 2.8
