Combinators

The API cross references give an immediate access to relevant interfaces and classes.

Root Glyph

The root glyph is specific in that it holds a reference to the facade.

Change Graphical Context

The attributes attached to a change graphical context are inherited by all subsequent children. Resources specification with a style is preferable to the use of an anonymous way with explicit font and color. When drawing the previous graphical context is saved in a context memento.

Horizontal

An horizontal arranges its children in horizontal mode. The space between consecutive element is given by the interword. The alignement is made between the exit point and the entry point of two consecutive elements. The only formatting action it knows on its own is reducing the interword.

Here are some implementation issues relative to optimization of such basic combinator.

Vertical

A vertical arranges its children in vertical mode. The space between consecutive lines is given by the interline. The indentation is a withdrawal applied to each element except the first. The only formatting action it knows on its own is reducing the indentation.

Here are some implementation issues relative to optimization of such basic combinator.

Paragraph

A paragraph puts its elements in horizontal mode while there is enough room till the right margin. Next it switchs to a new line and so on. So it can be view as a vertical whose each element is an horizontal. In fact, we use for the implementation Line and Column which are some kind of horizontal and vertical. Their behaviour only differ when formatting as an overflow will trigger a new line action.

Lighweight Component Adapter

A lightweight component adapter holds a reference to a java lightweight component. Its allows glyphs and java lightweight components to be mixed.

Decorations

A decorated glyph holds a reference to its component. Its default behavior is to delegate all operations. Its main purpose is adding reponsibilities, as subclasses are free to add specific operations.
