FieldView(Element elem)
Constructs a new FieldView wrapped on an element.
|
| Modifier and Type | Method and Description |
|---|---|
protected Shape |
adjustAllocation(Shape a)
Adjusts the allocation given to the view
to be a suitable allocation for a text field.
|
protected FontMetrics |
getFontMetrics()
Fetches the font metrics associated with the component hosting
this view.
|
float |
getPreferredSpan(int axis)
Determines the preferred span for this view along an
axis.
|
int |
getResizeWeight(int axis)
Determines the resizability of the view along the
given axis.
|
void |
insertUpdate(DocumentEvent changes,
Shape a,
ViewFactory f)
Gives notification that something was inserted into the document
in a location that this view is responsible for.
|
Shape |
modelToView(int pos,
Shape a,
Position.Bias b)
Provides a mapping from the document model coordinate space
to the coordinate space of the view mapped to it.
|
void |
paint(Graphics g,
Shape a)
Renders using the given rendering surface and area on that surface.
|
void |
removeUpdate(DocumentEvent changes,
Shape a,
ViewFactory f)
Gives notification that something was removed from the document
in a location that this view is responsible for.
|
int |
viewToModel(float fx,
float fy,
Shape a,
Position.Bias[] bias)
Provides a mapping from the view coordinate space to the logical
coordinate space of the model.
