## Implemented Interfaces

GdauiCloud implements AtkImplementorIface, GtkBuildable, GtkOrientable and GdauiDataSelector.

## Includes

    #include <libgda/thread-wrapper/gda-thread-wrapper.h>

## Description

The GdauiCloud widget displays a string for each row in a GdaDataModel for which the size is variable (determined either by some data in the data model, or by a function provided by the programmer).

Depending on the selection mode of the widget, each string can be selected by the user and the "selection-changed" signal is emitted.
