Class ComponentView
- SwingConstants
A
View
implementation that is able to render arbitrary
Component
s. This uses the attribute
StyleConstants.ComponentAttribute
to determine the
Component
that should be rendered. This
Component
becomes a direct child of the
JTextComponent
that contains
this
ComponentView
, so this view must not be shared between
multiple
JTextComponent
s.

ComponentView
public ComponentView(Element elem)
Creates a new instance of ComponentView
for the specified
Element
.
elem
- the element that this View
is rendering
getAlignment
public float getAlignment(int axis)
Returns the alignment of this View
along the specified axis.
- getAlignment in interface View
- the alignment of this
View
along the specified axis
getComponent
public final Component getComponent()
Returns the Component
that is rendered by this
ComponentView
.
- the
Component
that is rendered by this
ComponentView
paint
public void paint(Graphics g,
Shape a)
The real painting behavour is performed by normal component painting,
triggered by the text component that hosts this view. This method does
not paint by itself. However, it sets the size of the component according
to the allocation that is passed here.
- paint in interface View
g
- the graphics contexta
- the allocation of the child
setParent
public void setParent(View p)
This sets up the component when the view is added to its parent, or
cleans up the view when it is removed from its parent.
When this view is added to a parent view, the component of this view
is added to the container that hosts this view. When p
is
null
, then the view is removed from it's parent and we have
to also remove the component from it's parent container.
- setParent in interface View
p
- the parent view or null
if this view is removed
from it's parent
viewToModel
public int viewToModel(float x,
float y,
Shape a,
Position.Bias[] b)
Maps coordinates from the View
's space into a position
in the document model.
- viewToModel in interface View
x
- the x coordinate in the view spacey
- the y coordinate in the view spacea
- the allocation of this View
b
- the bias to use
- the position in the document that corresponds to the screen
coordinates
x, y
