Description

Widget that displays any object that implements the TreeModel interface.

Please refer to the tree widget conceptual overview for an overview of all the objects and data types related to the tree widget and how they work together.

Several different coordinate systems are exposed in the GtkTreeView API. These are:

Coordinate systems in GtkTreeView API:

  • Widget coordinates: Coordinates relative to the widget (usually widget->window).
  • Bin window coordinates: Coordinates relative to the window that GtkTreeView renders to.
  • Tree coordinates: Coordinates relative to the entire scrollable area of GtkTreeView. These coordinates start at (0, 0) for row 0 of the tree.

Several functions are available for converting between the different coordinate systems. The most common translations are between widget and bin window coordinates and between bin window and tree coordinates. For the former you can use treeViewConvertWidgetToBinWindowCoords (and vice versa), for the latter treeViewConvertBinWindowToTreeCoords (and vice versa).

GtkTreeView as GtkBuildable

The GtkTreeView implementation of the GtkBuildable interface accepts TreeViewColumn objects as <child> elements and exposes the internal TreeSelection in UI definitions.

An example of a UI definition fragment with GtkTreeView:

xml code

<object class="GtkTreeView" id="treeview">
  <property name="model">liststore1</property>
  <child>
    <object class="GtkTreeViewColumn" id="test-column">
      <property name="title">Test</property>
      <child>
        <object class="GtkCellRendererText" id="test-renderer"/>
        <attributes>
          <attribute name="text">1</attribute>
        </attributes>
      </child>
    </object>
  </child>
  <child internal-child="selection">
    <object class="GtkTreeSelection" id="selection">
      <signal name="changed" handler="on_treeview_selection_changed"/>
    </object>
  </child>
</object>

CSS nodes

plain code

treeview.view
├── header
│   ├── <column header>
┊   ┊
│   ╰── <column header>
│
╰── [rubberband]

GtkTreeView has a main CSS node with name treeview and style class .view. It has a subnode with name header, which is the parent for all the column header widgets' CSS nodes. For rubberband selection, a subnode with name rubberband is used.

treeView: a TreeView

-> Maybe TreePath

path: a TreePath for the row, or Nothing to get only horizontal coordinates

-> Maybe b

column: a TreeViewColumn for the column, or Nothing to get only vertical coordiantes

-> m Rectangle 

Fills the bounding rectangle in bin_window coordinates for the cell at the row specified by path and the column specified by column. If path is Nothing, or points to a node not found in the tree, the y and height fields of the rectangle will be filled with 0. If column is Nothing, the x and width fields will be filled with 0. The returned rectangle is equivalent to the backgroundArea passed to cellRendererRender. These background areas tile to cover the entire bin window. Contrast with the cellArea, returned by treeViewGetCellArea, which returns only the cell itself, excluding surrounding borders and the tree expander area.

-> Maybe b

column: a TreeViewColumn for the column, or Nothing to get only vertical coordinates

-> m Rectangle 

Fills the bounding rectangle in bin_window coordinates for the cell at the row specified by path and the column specified by column. If path is Nothing, or points to a path not currently displayed, the y and height fields of the rectangle will be filled with 0. If column is Nothing, the x and width fields will be filled with 0. The sum of all cell rects does not cover the entire tree; there are extra pixels in between rows, for example. The returned rectangle is equivalent to the cellArea passed to cellRendererRender. This function is only valid if treeView is realized.

getColumn

treeViewGetColumn Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a) 
=> a

=> a

treeView: A TreeView

-> m (Maybe TreePath, Maybe TreeViewColumn) 

Fills in path and focusColumn with the current path and focus column. If the cursor isn’t currently set, then *path will be Nothing. If no column currently has focus, then *focusColumn will be Nothing.

The returned TreePath must be freed with treePathFree when you are done with it.

getDestRowAtPos

treeViewGetDestRowAtPos Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a) 
=> a

treeView: a TreeView

-> m (Bool, Maybe TreePath, TreeViewDropPosition)

Returns: whether there is a row at the given position, True if this is indeed the case.

Determines the destination row for a given position. dragX and dragY are expected to be in widget coordinates. This function is only meaningful if treeView is realized. Therefore this function will always return False if treeView is not realized or does not have a model.

-> m (Bool, Maybe TreePath, Maybe TreeViewColumn, Int32, Int32)

Returns: True if a row exists at that coordinate.

Finds the path at the point (x, y), relative to bin_window coordinates (please see treeViewGetBinWindow). That is, x and y are relative to an events coordinates. x and y must come from an event on the treeView only where event->window == gtk_tree_view_get_bin_window (). It is primarily for things like popup menus. If path is non-Nothing, then it will be filled with the TreePath at that point. This path should be freed with treePathFree. If column is non-Nothing, then it will be filled with the column at that point. cellX and cellY return the coordinates relative to the cell background (i.e. the backgroundArea passed to cellRendererRender). This function is only meaningful if treeView is realized. Therefore this function will always return False if treeView is not realized or does not have a model.

For converting widget coordinates (eg. the ones you get from GtkWidgetqueryTooltip), please see treeViewConvertWidgetToBinWindowCoords.

-> Int32

x: the x coordinate (relative to widget coordinates)

-> Int32

y: the y coordinate (relative to widget coordinates)

-> Bool

keyboardTip: whether this is a keyboard tooltip or not

-> m (Bool, Int32, Int32, Maybe TreeModel, TreePath, TreeIter)

Returns: whether or not the given tooltip context points to a row.

This function is supposed to be used in a Widget::queryTooltip signal handler for TreeView. The x, y and keyboardTip values which are received in the signal handler, should be passed to this function without modification.

The return value indicates whether there is a tree view row at the given coordinates (True) or not (False) for mouse tooltips. For keyboard tooltips the row returned will be the cursor row. When True, then any of model, path and iter which have been provided will be set to point to that row and the corresponding model. x and y will always be converted to be relative to treeView’s bin_window if keyboardTooltip is False.

=> a

treeView: A TreeView.

-> b

column: The TreeViewColumn to remove.

-> m Int32

Returns: The number of columns in treeView after removing.

Removes column from treeView.

rowActivated

treeViewRowActivated Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a, IsTreeViewColumn b) 
=> a

treeView: A TreeView

-> TreePath

path: The TreePath to be activated.

-> b

column: The TreeViewColumn to be activated.

-> m () 

Activates the cell determined by path and column.

rowExpanded

treeViewRowExpanded Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a) 
=> a

treeView: A TreeView.

-> TreePath

path: A TreePath to test expansion state.

-> m Bool

Returns: True if path is expanded.

Returns True if the node pointed to by path is expanded in treeView.

scrollToCell

treeViewScrollToCell Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a, IsTreeViewColumn b) 
=> a

treeView: A TreeView.

-> Maybe TreePath

path: The path of the row to move to, or Nothing.

-> Maybe b

column: The TreeViewColumn to move horizontally to, or Nothing.

-> Bool

useAlign: whether to use alignment arguments, or False.

-> Float

rowAlign: The vertical alignment of the row specified by path.

-> Float

colAlign: The horizontal alignment of the column specified by column.

-> m () 

Moves the alignments of treeView to the position specified by column and path. If column is Nothing, then no horizontal scrolling occurs. Likewise, if path is Nothing no vertical scrolling occurs. At a minimum, one of column or path need to be non-Nothing. rowAlign determines where the row is placed, and colAlign determines where column is placed. Both are expected to be between 0.0 and 1.0. 0.0 means left/top alignment, 1.0 means right/bottom alignment, 0.5 means center.

If useAlign is False, then the alignment arguments are ignored, and the tree does the minimum amount of work to scroll the cell onto the screen. This means that the cell will be scrolled to the edge closest to its current position. If the cell is currently visible on the screen, nothing is done.

This function only works if the model is set, and path is a valid row on the model. If the model changes before the treeView is realized, the centered path will be modified to reflect this change.

scrollToPoint

treeViewScrollToPoint Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a) 
=> a

treeView: a TreeView

-> Int32

treeX: X coordinate of new top-left pixel of visible area, or -1

-> Int32

treeY: Y coordinate of new top-left pixel of visible area, or -1

-> m () 

Scrolls the tree view such that the top-left corner of the visible area is treeX, treeY, where treeX and treeY are specified in tree coordinates. The treeView must be realized before this function is called. If it isn't, you probably want to be using treeViewScrollToCell.

If either treeX or treeY are -1, then that direction isn’t scrolled.

setActivateOnSingleClick

treeViewSetActivateOnSingleClick Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a) 
=> a

treeView: a TreeView

-> Bool

single: True to emit row-activated on a single click

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a) 
=> a

treeView: A TreeView.

-> Maybe TreeViewColumnDropFunc

func: A function to determine which columns are reorderable, or Nothing.

-> m () 

Sets a user function for determining where a column may be dropped when dragged. This function is called on every column pair in turn at the beginning of a column drag to determine where a drop can take place. The arguments passed to func are: the treeView, the TreeViewColumn being dragged, the two TreeViewColumn s determining the drop spot, and userData. If either of the TreeViewColumn arguments for the drop spot are Nothing, then they indicate an edge. If func is set to be Nothing, then treeView reverts to the default behavior of allowing all columns to be dropped everywhere.

treeViewSetCursor Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a, IsTreeViewColumn b) 
=> a

treeView: A TreeView

-> TreePath

path: A TreePath

-> Maybe b

focusColumn: A TreeViewColumn, or Nothing

-> Bool

startEditing: True if the specified cell should start being edited.

-> m () 

Sets the current keyboard focus to be at path, and selects it. This is useful when you want to focus the user’s attention on a particular row. If focusColumn is not Nothing, then focus is given to the column specified by it. Additionally, if focusColumn is specified, and startEditing is True, then editing should be started in the specified cell. This function is often followed by gtkWidgetGrabFocus (treeView) in order to give keyboard focus to the widget. Please note that editing can only happen when the widget is realized.

If path is invalid for model, the current cursor (if any) will be unset and the function will return without failing.

setCursorOnCell

treeViewSetCursorOnCell Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a, IsTreeViewColumn b, IsCellRenderer c) 
=> a

treeView: A TreeView

-> TreePath

path: A TreePath

-> Maybe b

focusColumn: A TreeViewColumn, or Nothing

-> Maybe c

focusCell: A CellRenderer, or Nothing

-> Bool

startEditing: True if the specified cell should start being edited.

-> m () 

Sets the current keyboard focus to be at path, and selects it. This is useful when you want to focus the user’s attention on a particular row. If focusColumn is not Nothing, then focus is given to the column specified by it. If focusColumn and focusCell are not Nothing, and focusColumn contains 2 or more editable or activatable cells, then focus is given to the cell specified by focusCell. Additionally, if focusColumn is specified, and startEditing is True, then editing should be started in the specified cell. This function is often followed by gtkWidgetGrabFocus (treeView) in order to give keyboard focus to the widget. Please note that editing can only happen when the widget is realized.

If path is invalid for model, the current cursor (if any) will be unset and the function will return without failing.

setDragDestRow

treeViewSetDragDestRow Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a) 
=> a

treeView: a TreeView

-> Maybe TreePath

path: The path of the row to highlight, or Nothing

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a) 
=> a

treeView: A TreeView

-> Bool

enableSearch: True, if the user can search interactively

-> m () 

If enableSearch is set, then the user can type in text to search through the tree interactively (this is sometimes called "typeahead find").

Note that even if this is False, the user can still initiate a search using the “start-interactive-search” key binding.

setEnableTreeLines

treeViewSetEnableTreeLines Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a) 
=> a

treeView: a TreeView

-> Bool

enable: True to enable fixed height mode

treeViewSetHoverSelection Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a) 
=> a

treeView: a TreeView

-> Bool

hover: True to enable hover selection mode

-> m () 

Enables or disables the hover selection mode of treeView. Hover selection makes the selected row follow the pointer. Currently, this works only for the selection modes SelectionModeSingle and SelectionModeBrowse.

Since: 2.6

setLevelIndentation

treeViewSetLevelIndentation Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a) 
=> a

treeView: a TreeView

-> Int32

indentation: the amount, in pixels, of extra indentation in treeView.

-> m () 

Sets the amount of extra indentation for child levels to use in treeView in addition to the default indentation. The value should be specified in pixels, a value of 0 disables this feature and in this case only the default indentation will be used. This does not have any visible effects for lists.

Since: 2.12

setModel

treeViewSetModel Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a, IsTreeModel b) 
=> a

treeView: A TreeView.

-> Maybe b

model: The model.

-> m () 

Sets the model for a TreeView. If the treeView already has a model set, it will remove it before setting the new model. If model is Nothing, then it will unset the old model.

setReorderable

treeViewSetReorderable Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a) 
=> a

treeView: A TreeView.

-> Bool

reorderable: True, if the tree can be reordered.

-> m () 

This function is a convenience function to allow you to reorder models that support the TreeDragSourceIface and the TreeDragDestIface. Both TreeStore and ListStore support these. If reorderable is True, then the user can reorder the model by dragging and dropping rows. The developer can listen to these changes by connecting to the model’s TreeModel::rowInserted and TreeModel::rowDeleted signals. The reordering is implemented by setting up the tree view as a drag source and destination. Therefore, drag and drop can not be used in a reorderable view for any other purpose.

This function does not give you any degree of control over the order -- any reordering is allowed. If more control is needed, you should probably handle drag and drop manually.

setRowSeparatorFunc

treeViewSetRowSeparatorFunc Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a) 
=> a

treeView: a TreeView

-> Maybe TreeViewRowSeparatorFunc

func: a TreeViewRowSeparatorFunc

-> m () 

Sets the row separator function, which is used to determine whether a row should be drawn as a separator. If the row separator function is Nothing, no separators are drawn. This is the default value.

Since: 2.6

treeViewSetRubberBanding Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a) 
=> a

treeView: a TreeView

-> Bool

enable: True to enable rubber banding

-> m () 

Enables or disables rubber banding in treeView. If the selection mode is GTK_SELECTION_MULTIPLE, rubber banding will allow the user to select multiple rows by dragging the mouse.

Since: 2.10

setRulesHint

treeViewSetRulesHint Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a) 
=> a

treeView: a TreeView

-> Bool

setting: True if the tree requires reading across rows

-> m () 

Deprecated: (Since version 3.14)

Sets a hint for the theme to draw even/odd rows in the treeView with different colors, also known as "zebra striping".

This function tells the GTK+ theme that the user interface for your application requires users to read across tree rows and associate cells with one another.

Do not use it just because you prefer the appearance of the ruled tree; that’s a question for the theme. Some themes will draw tree rows in alternating colors even when rules are turned off, and users who prefer that appearance all the time can choose those themes. You should call this function only as a semantic hint to the theme engine that your tree makes alternating colors useful from a functional standpoint (since it has lots of columns, generally).

setSearchColumn

treeViewSetSearchColumn Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a) 
=> a

treeView: A TreeView

-> Int32

column: the column of the model to search in, or -1 to disable searching

-> m () 

Sets column as the column where the interactive search code should search in for the current model.

If the search column is set, users can use the “start-interactive-search” key binding to bring up search popup. The enable-search property controls whether simply typing text will also start an interactive search.

Note that column refers to a column of the current model. The search column is reset to -1 when the model is changed.

setSearchEntry

treeViewSetSearchEntry Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a, IsEntry b) 
=> a

treeView: A TreeView

-> Maybe b

entry: the entry the interactive search code of treeView should use or Nothing

-> m () 

Sets the entry which the interactive search code will use for this treeView. This is useful when you want to provide a search entry in our interface at all time at a fixed position. Passing Nothing for entry will make the interactive search code use the built-in popup entry again.

Since: 2.10

setSearchEqualFunc

treeViewSetSearchEqualFunc Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a) 
=> a

treeView: A TreeView

-> TreeViewSearchEqualFunc

searchEqualFunc: the compare function to use during the search

-> m () 

Sets the compare function for the interactive search capabilities; note that somewhat like strcmp() returning 0 for equality TreeViewSearchEqualFunc returns False on matches.

setSearchPositionFunc

treeViewSetSearchPositionFunc Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a) 
=> a

treeView: A TreeView

-> Maybe TreeViewSearchPositionFunc

func: the function to use to position the search dialog, or Nothing to use the default search position function

setShowExpanders

treeViewSetShowExpanders Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a) 
=> a

treeView: a TreeView

-> Bool

enabled: True to enable expander drawing, False otherwise.

-> m () 

Sets whether to draw and enable expanders and indent child rows in treeView. When disabled there will be no expanders visible in trees and there will be no way to expand and collapse rows by default. Also note that hiding the expanders will disable the default indentation. You can set a custom indentation in this case using treeViewSetLevelIndentation. This does not have any visible effects for lists.

Since: 2.12

setTooltipCell

treeViewSetTooltipCell Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a, IsTooltip b, IsTreeViewColumn c, IsCellRenderer d) 
=> a

treeView: a TreeView

-> b

tooltip: a Tooltip

-> Maybe TreePath

path: a TreePath or Nothing

-> Maybe c

column: a TreeViewColumn or Nothing

-> Maybe d

cell: a CellRenderer or Nothing

-> m () 

Sets the tip area of tooltip to the area path, column and cell have in common. For example if path is Nothing and column is set, the tip area will be set to the full area covered by column. See also tooltipSetTipArea.

Note that if path is not specified and cell is set and part of a column containing the expander, the tooltip might not show and hide at the correct position. In such cases path must be set to the current node under the mouse cursor for this function to operate correctly.

See also treeViewSetTooltipColumn for a simpler alternative.

Since: 2.12

setTooltipColumn

treeViewSetTooltipColumn Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a) 
=> a

treeView: a TreeView

-> Int32

column: an integer, which is a valid column number for treeView’s model

-> m () 

If you only plan to have simple (text-only) tooltips on full rows, you can use this function to have TreeView handle these automatically for you. column should be set to the column in treeView’s model containing the tooltip texts, or -1 to disable this feature.

When enabled, Widget:hasTooltip will be set to True and treeView will connect a Widget::queryTooltip signal handler.

Note that the signal handler sets the text with tooltipSetMarkup, so &, <, etc have to be escaped in the text.

Since: 2.12

setTooltipRow

treeViewSetTooltipRow Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a, IsTooltip b) 
=> a

treeView: a TreeView

-> b

treeViewUnsetRowsDragDest Source #

Arguments

:: (HasCallStack, MonadIO m, IsTreeView a) 
=> a

treeView: a TreeView

-> m () 

Undoes the effect of treeViewEnableModelDragDest. Calling this method sets TreeView:reorderable to False.
