Public Methods

Method	Description
AddControl ( IControlHabanero control ) : IControlHabanero	Adds a control to the layout
AddGlue ( ) : void	Adds glue that connects two controls together. For example, if you've just added a label and want to ensure the textbox you're adding next is always next to the label, add glue between adding the label and adding the textbox. In this way, if you resize the control such that the textbox doesn't fit on the line, both the label and the textbox will move to the next line together. This must be called immediatly after adding the label. The next control to be added will be the control the label is glued to.
FlowLayoutManager ( IControlHabanero managedControl, IControlFactory controlFactory ) : System	Constructor to initialise a new manager
NewLine ( ) : void	Inserts a new line. This is like a line break or carriage return for controls. The next control will start at the control's margin (depending on alignment).
RemoveControl ( IControlHabanero controlHabanero ) : IControlHabanero	Removes a control.
