Public Member Functions

Signal Handlers

• virtual void on_set_scroll_adjustments (Adjustment *hadjustment, Adjustment *vadjustment)

  Called when a tree view is added to a scrolling aware parent.
  

• virtual void on_row_activated (const TreePath &path, TreeViewColumn &column)

  Called when the cell determined by path and column is activated.
  

• virtual bool on_test_expand_row (const TreeIter &iter, const TreePath &path)

  Called to determine if the row identified by iter and path has child rows and can be opened.
  

• virtual bool on_test_collapse_row (const TreeIter &iter, const TreePath &path)

  Called to determine if the row identified by iter and path has child rows that are visible and can be collapsed.
  

• virtual void on_row_expanded (const TreeIter &iter, const TreePath &path)

  Called when the row determined by iter and path is opened so its children are visible.
  

• virtual void on_row_collapsed (const TreeIter &iter, const TreePath &path)

  Called when the row determined by iter and path is collapsed to hide its child rows.
  

• virtual void on_columns_changed ()

  Called whenever the order or number of columns in the tree view changes.
  

• virtual void on_cursor_changed ()

  Called whenever the current keyboard focus changes.

Member Function Documentation

virtual void Xfc::Gtk::TreeViewSignals::on_row_activated (  const TreePath &  path, TreeViewColumn &  column )  [virtual]

Called when the cell determined by path and column is activated. Parameters: path  The TreePath being activated. column  The TreeViewColumn being activated.

virtual void Xfc::Gtk::TreeViewSignals::on_row_collapsed (  const TreeIter &  iter, const TreePath &  path )  [virtual]

Called when the row determined by iter and path is collapsed to hide its child rows. Parameters: iter  A valid iterator pointing to path. path  The path to the row being collapsed.

virtual void Xfc::Gtk::TreeViewSignals::on_row_expanded (  const TreeIter &  iter, const TreePath &  path )  [virtual]

Called when the row determined by iter and path is opened so its children are visible. Parameters: iter  A valid iterator pointing to path. path  The path to the row being expanded.

virtual void Xfc::Gtk::TreeViewSignals::on_set_scroll_adjustments (  Adjustment *  hadjustment, Adjustment *  vadjustment )  [virtual]

Called when a tree view is added to a scrolling aware parent. Parameters: hadjustment  The horizontal adjustment. vadjustment  The vertical adjustment.

virtual bool Xfc::Gtk::TreeViewSignals::on_test_collapse_row (  const TreeIter &  iter, const TreePath &  path )  [virtual]

Called to determine if the row identified by iter and path has child rows that are visible and can be collapsed. Parameters: iter  A valid iterator pointing to path. path  The path to the row being checked. Returns: true if the row has child rows that are visible and can be collapsed.

virtual bool Xfc::Gtk::TreeViewSignals::on_test_expand_row (  const TreeIter &  iter, const TreePath &  path )  [virtual]

Called to determine if the row identified by iter and path has child rows and can be opened. Parameters: iter  A valid iterator pointing to path. path  The path to the row being checked. Returns: true if the row has chil rows and can be expanded.
