);
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.
GtkWidget * gdaui_cloud_new (GdaDataModel *model
,gint label_column
,gint weight_column
);
