Modelled views are structural models of graphical user interfaces defined in org.simantics.views*
Contents
Basic concepts
A modelled view is a structural model of controls. The model configuration can be evaluated to produce a scene graph as defined in org.simantics.scenegraph. A single view configuration can be evaluated into multiple different scene graphs with different node types (e.g. SWT, AWT, PDF, HTML). The evaluation is done in the context of org.simantics.db.layer0.variable.Variable.
The properties of controls in a modelled view are often defined as functions of an external input assigned to the evaluation context e.g. a view can be defined to represent the current workspace selection. In the control hierarchy, relative references can also be modelled e.g. an action can be applied on an output of a specific control. It is also possible to declare a substructure of controls as a type such that some properties in the substructure are defined as functions of some interface properties declared in the type and defined in instances of that type.
Modelling
Composite
Composites are used mainly to lay out other controls.
Label
Labels display read-only text.
Text
Text represents an editable text, which produces instant notification of any changes.
Button
Button represents a standard button.
Combo
Combo represents a standard drop-down.
Tracked Text
Tracked text represents an editable text, which produces change notifications only when the editing operation ends.
Explorer
Explorer represents a browse context as tree.
TabFolder
Tab folders represent a stack of composites.
Scrolled Composite
Scrolled composite is a composite which does not impose its size restrictions on its children.
Combo2
Combo2 is a variation of Combo.
