Implemented Interfaces
GdauiCloud implements AtkImplementorIface, GtkBuildable, GtkOrientable and GdauiDataSelector.
Properties
"label-column" gint : Read / Write "max-scale" gdouble : Read / Write "min-scale" gdouble : Read / Write "model" GdaDataModel* : Read / Write "weight-column" gint : Read / Write
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.
