Class com.sun.java.swing.text.IconView
java.lang.Object

+----com.sun.java.swing.text.AbstractView
|
+----com.sun.java.swing.text.IconView
- public class IconView
- extends AbstractView
Icon decorator that implements the view interface. The
entire element is used to represent the icon. This acts
as a gateway from the display-only View implementations to
interactive lightweight icons (ie it allows icons
to be embedded into the View hierarchy. The parent of the icon
is the container that is handed out by the associated view
factory.
-
IconView(Element, Icon, ViewFactory)
- Creates a new view that represents an element.
-
changedUpdate(DocumentEvent, Shape, ViewFactory)
- Gives notification from the document that attributes were changed
in a location that this view is responsible for.
-
getPreferredShape(Shape, ViewFactory)
- Calculates the desired shape of the icon.
-
insertUpdate(DocumentEvent, Shape, ViewFactory)
- Gives notification that something was inserted into the document
in a location that this view is responsible for.
-
modelToView(int, Shape, ViewFactory)
- Provides a mapping from the document model coordinate space
to the coordinate space of the view mapped to it.
-
paint(Graphics, Shape, ViewFactory)
- Paints the icon.
-
removeUpdate(DocumentEvent, Shape, ViewFactory)
- Gives notification that something was removed from the document
in a location that this view is responsible for.
-
viewToModel(Point, Shape, ViewFactory)
- Provides a mapping from the view coordinate space to the logical
coordinate space of the model.
IconView
public IconView(Element elem,
Icon c,
ViewFactory f)
- Creates a new view that represents an element.
- Parameters:
- elem - the element to create a view for
- c - the icon
- f - the view factory
paint
public void paint(Graphics g,
Shape a,
ViewFactory f)
- Paints the icon.
The real paint behavior occurs naturally from the association
that the icon has with its parent container (the same
container hosting this view), so this simply allows us to
position the icon properly relative to the view. Since
the coordinate system for the view is simply the parent
containers, positioning the child icon is easy.
- Parameters:
- g - the rendering surface to use
- a - the allocated region to render into
- f - the view factor to use if children need to be created
- Overrides:
- paint in class AbstractView
- See Also:
- paint
getPreferredShape
public Shape getPreferredShape(Shape candidate,
ViewFactory f)
- Calculates the desired shape of the icon. The preferred
size of the icon is used unless it doesn't fit within the
parents constraints. If it doesn't fit, it shrinks the
icon to the maximum of either the constraint or the
mimimum size.
- Parameters:
- candidate - the shape candidate
- f - the view factory
- Returns:
- the desired shape
- Overrides:
- getPreferredShape in class AbstractView
- See Also:
- getPreferredShape
modelToView
public Shape modelToView(int pos,
Shape a,
ViewFactory f) throws BadLocationException
- Provides a mapping from the document model coordinate space
to the coordinate space of the view mapped to it.
- Parameters:
- pos - the position to convert
- a - the allocated region to render into
- f - the factory to use if children need to be created
- Returns:
- the bounding box of the given position
- Throws: BadLocation
- if the given position does not represent a
valid location in the associated document
- Overrides:
- modelToView in class AbstractView
- See Also:
- modelToView
viewToModel
public int viewToModel(Point pt,
Shape a,
ViewFactory f)
- Provides a mapping from the view coordinate space to the logical
coordinate space of the model.
- Parameters:
- pt - the view location to convert
- a - the allocated region to render into
- f - the factory to use if children need to be created
- Returns:
- the location within the model that best represents the
given point of view
- Overrides:
- viewToModel in class AbstractView
- See Also:
- viewToModel
insertUpdate
public void insertUpdate(DocumentEvent evnt,
Shape a,
ViewFactory f)
- Gives notification that something was inserted into the document
in a location that this view is responsible for.
- Parameters:
- evnt - the change information from the associated document
- a - the current allocation of the view
- the - factory to use to rebuilld if the view has children
- Overrides:
- insertUpdate in class AbstractView
removeUpdate
public void removeUpdate(DocumentEvent evnt,
Shape a,
ViewFactory f)
- Gives notification that something was removed from the document
in a location that this view is responsible for.
- Parameters:
- evnt - the change information from the associated document
- a - the current allocation of the view
- the - factory to use to rebuild if the view has children
- Overrides:
- removeUpdate in class AbstractView
changedUpdate
public void changedUpdate(DocumentEvent e,
Shape a,
ViewFactory f)
- Gives notification from the document that attributes were changed
in a location that this view is responsible for.
- Parameters:
- e - the change information from the associated document
- a - the current allocation of the view
- f - teh factory to use to rebuild if the view has children
- Overrides:
- changedUpdate in class AbstractView
