How to get the row at cursor of GtkListBox?

[taozuhong]

Sometimes, the row at cursor and the selected row in the GtkListBox are different, while popping the context menu on the row at cursor but not the selected row:

So how to get the row at cursor?

The current solution I used:

int x = 0, y = 0;
Gdk.Device? pointer = this.get_display().get_default_seat().get_pointer();
this.get_window().get_device_position(pointer, out x, out y, null);
m_list_row_pointer = m_expr_list_box.get_row_at_y(y);
