+ For instance, with the horizontal orientation,

+ starting a new row under the previous row when 
+ necessary. Reducing the width in this case will 
+ require more rows, so a larger height will be 
+ requested.
+
+ Likewise, with the vertical orientation, 
+ the widgets will be arranged from top to bottom, 
+ starting a new column to the right when necessary. 
+ Reducing the height will require more columns, 
+ so a larger width will be requested.
+
+ The children of a GtkFlowBox can be dynamically 
+ sorted and filtered.`)
