Description

A widget which displays a list of icons in a grid

Module available since Gtk+ version 2.6

Synopsis

Detail

IconView provides an alternative view on a list model. It displays the model as a grid of icons with labels. Like TreeView, it allows to select one or multiple items (depending on the selection mode, see iconViewSetSelectionMode). In addition to selection with the arrow keys, IconView supports rubberband selection, which is controlled by dragging the pointer.

Methods

iconViewSetModel Source

Arguments

:: (IconViewClass self, TreeModelClass model)
=> self
-> Maybe model	`model` - The model.

=> self
-> IO (Maybe TreeModel)	returns a `TreeModel`, or `Nothing` if none is currently being used.

Returns the model the IconView is based on. Returns Nothing if the model is unset.

iconViewSetTextColumn Source

Arguments

:: IconViewClass self
=> self
-> ColumnId row String	`column` - A column in the currently used model.

iconViewPathIsSelected Source

Arguments

:: IconViewClass self

iconViewGetSelectedItems Source

Arguments

:: IconViewClass self
=> self
-> IO [TreePath]	returns a list of `TreePath`s, one for each selected row.

Creates a list of paths of all selected items. Additionally, if you are planning on modifying the model after calling this function, you may want to convert the returned list into a list of TreeRowReferences. To do this, you can use treeRowReferenceNew.

Available since Gtk+ version 2.8

iconViewSetCursor Source

Arguments

:: (IconViewClass self, CellRendererClass cell)
=> self
-> Either TreePath cell	the path or the cell
-> Bool	`startEditing` - `True` if the specified cell should start being edited.
-> IO ()

Given Left path as argument , 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 item. If Right cell is given, then focus is given to the cell specified by it. Additionally, if startEditing is True, then editing should be started in the specified cell.

This function is often followed by widgetGrabFocus in order to give keyboard focus to the widget. Please note that editing can only happen when the widget is realized.

Available since Gtk+ version 2.8

iconViewGetCursor Source

Arguments

:: IconViewClass self
=> self
-> IO (TreePath, Maybe CellRenderer)	returns a `path` to the cursor and a `cell` if the widget has the input focus

Return a path and a cell with the current cursor path and cell. If the cursor isn't currently set, then [] will be returned for the path. If no cell currently has focus, then cell will be Nothing.

Available since Gtk+ version 2.8

iconViewScrollToPath Source

Arguments

:: IconViewClass self
=> self
-> TreePath	`path` - The path of the item to move to.
-> Bool	`useAlign` - whether to use alignment arguments, or `False`.
-> Float	`rowAlign` - The vertical alignment of the item specified by `path`.
-> Float	`colAlign` - The horizontal alignment of the item specified by `path`.
-> IO ()

Moves the alignments of iconView to the position specified by path. 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 item onto the screen. This means that the item will be scrolled to the edge closest to its current position. If the item 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 iconView is realized, the centered path will be modified to reflect this change.

Available since Gtk+ version 2.8

iconViewGetVisibleRange Source

Arguments

:: IconViewClass self
=> self
-> IO (Maybe (TreePath, TreePath))	returns the first and last visible path, the return value `Nothing` if every element is visible

Retrieve the first and last visible path. Note that there may be invisible paths inbetween.

Available since Gtk+ version 2.8

iconViewEnableModelDragSource Source

Arguments

:: IconViewClass self
=> self
-> [Modifier]	`startButtonMask` - Mask of allowed buttons to start drag
-> TargetList	`targets` - the list of targets that the the view will support
-> [DragAction]	`actions` - flags denoting the possible actions for a drag from this widget
-> IO ()

Turns iconView into a drag source for automatic DND.

Available since Gtk+ version 2.10

iconViewEnableModelDragDest Source

Arguments

:: IconViewClass self
=> self
-> TargetList	`targets` - the list of targets that the the view will support
-> [DragAction]	`actions` - flags denoting the possible actions for a drop into this widget
-> IO ()

Turns iconView into a drop destination for automatic DND.

Available since Gtk+ version 2.10

iconViewUnsetModelDragSource :: IconViewClass self => self -> IO ()Source

Undoes the effect of iconViewEnableModelDragSource.

Available since Gtk+ version 2.10

iconViewUnsetModelDragDest :: IconViewClass self => self -> IO ()Source

Undoes the effect of iconViewEnableModelDragDest.

iconViewSetReorderable Source

Arguments

:: IconViewClass self
=> self
-> Bool	`reorderable` - `True`, if the list of items can be reordered.
-> IO ()

Check if icons can be moved around.

Set whether the user can use drag and drop (DND) to reorder the rows in the store. This works on both TreeStore and ListStore models. If ro 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 signals. If you need to control which rows may be dragged or where rows may be dropped, you can override the treeDragSourceRowDraggable function in the default DND implementation of the model.
Available since Gtk+ version 2.8

iconViewGetReorderable Source

Arguments

:: IconViewClass self
=> self
-> IO Bool	returns `True` if the list can be reordered.
