GObject +----GtkTreeSelection
The GtkTreeSelection
object is a helper object to manage the selection
for a GtkTreeView
widget. The GtkTreeSelection
object is
automatically created when a new GtkTreeView
widget is created, and
cannot exist independentally of this widget. The primary reason the
GtkTreeSelection
objects exists is for cleanliness of code and API.
That is, there is no conceptual reason all these functions could not be
methods on the GtkTreeView
widget instead of a separate function.
The GtkTreeSelection
object is gotten from a GtkTreeView
by calling
gtkTreeViewGetSelection
. It can be manipulated to check the
selection status of the tree, as well as select and deselect individual
rows. Selection is done completely view side. As a result, multiple
views of the same model can have completely different selections.
Additionally, you cannot change the selection of a row on the model that
is not currently displayed by the view without expanding its parents
first.
One of the important things to remember when monitoring the selection of a view is that the
"changed"signal is mostly a hint. That is, it may only emit one signal when a range of rows is selected. Additionally, it may on occasion emit a ::changed signal when nothing has happened (mostly as a result of programmers calling select_row on an already selected row).
GtkTreeSelection
undocumented
changed(treeselection, user.data)
Emitted whenever the selection has (possibly) changed. Please note that this signal is mostly a hint. It may only be emitted once when a range of rows are selected, and it may occasionally be emitted when nothing has happened.
treeselection
the object which received the signal.
user.data
user data set when the signal handler was connected.
