Layout of platform specific graphical user interface widgets migrated between heterogeneous device platforms

A method of dynamically customizing the layout of a migratable application graphical user interface for a heterogeneous device platform, the method comprising:

• a) determining the presentation support capability of a display screen of a heterogeneous device platform;
• b) processing a node in a platform independent presentation model as a function of the determined presentation support capability and properties associated with the node, wherein a platform independent graphical user interface widget is also associated with the node;
• c) positioning a platform specific graphical user interface widget that corresponds to the platform independent graphical user interface widget on a page as a function of the properties;
• and
• d) splitting the platform independent graphical user interface widget among multiple pages when the page does not fit within the display screen.

A method of dynamically customizing the layout of a migratable application graphical user interface for a heterogeneous device platform, the method comprising:

• a) processing a node included in a platform independent presentation model of an application graphical user interface for placement in a first page, wherein a composite scalable graphical user interface component is associated with the node;
• b) comparing the size of the first page to the size of a display screen of a heterogeneous device platform;
• c) splitting the composite scalable graphical user interface component into at least two scalable graphical user interface components when the first page is too large to fit within the display screen;
• and
• d) dividing placement of the scalable graphical user interface components between the first page and at least one second page.
