Description

Note

This widget is available in PyGTK 2.6 and above.

The gtk.IconView widget provides an alternative view of a gtk.ListStore model. It displays the model as a grid of icons with labels. Like gtk.TreeView, you can select one or multiple items (depending on the selection mode, see the set_selection_mode() method for more information). In addition to selection with the arrow keys, gtk.IconView supports rubberband selection, which is controlled by dragging the pointer.

Constructor

    gtk.IconView(model=None)
model :A gtk.TreeModel, or None
Returns :a new gtk.IconView widget.

Note

This constructor is available in PyGTK 2.6 and above.

Note

This method is available in PyGTK 2.8 and above.

The scroll_to_path() method moves the alignments of the icon view to the position specified by path. row_align determines where the row is placed, and col_align 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 use_align is FALSE, then the alignment arguments are ignored, and the icon view 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 method only works if the model is set, and path is a valid row on the model. If the model changes before the icon view is realized, the centered path will be modified to reflect this change.

    def set_reorderable(reorderable)
reorderable :if TRUE the items are reorderable.

Note

This method is available in PyGTK 2.8 and above.

The set_reorderable() method sets the "reorderable" property to the value of reorderable. If reorderable is TRUE the user can reorder the model by dragging and dropping rows. The developer can listen to these changes by connecting to the model's "row_inserted" and "row_deleted" signals.

This method 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.
