A LayoutStyle contains four TextStyles, one each for data (data within controls), forms (form background and control captions), titles (form and grid titles) and menus (standard and context menus). It also contains various other settings that for example modify how controls and their captions are positioned by default in Layouts.
Each Layout can have a particular associated LayoutStyle, however it is recommended that this be left at null unless there is a particular requirement for it. Each Package that you develop can also have an associated LayoutStyle, and forms and grids that have no LayoutStyle of their own will be displayed in the Package style.
LayoutStyles can be applied at run time. You can apply a LayoutStyle to any object which implements the IStyled interface, which includes the IPWindow interface used in the Persistate abstract user interface scheme. This will immediately redisplay the IPWindow, including all Panes within it, in the new style.
Persistate supplies several LayoutStyles as standard. These include System which uses the operating system default colour scheme and the .Net default font. There is also System Large and System Extra Large, which are similar to System, but with larger font sizes.
