Constructor Detail

InlineView

public InlineView(Element elem)

Constructs a new view wrapped on an element.

Parameters:

elem - the element

insertUpdate

public void insertUpdate(DocumentEvent e,
                         Shape a,
                         ViewFactory f)

Gives notification that something was inserted into the document in a location that this view is responsible for. If either parameter is null, behavior of this method is implementation dependent.

Overrides:

insertUpdate in class GlyphView

Parameters:

e - the change information from the associated document

a - the current allocation of the view

f - the factory to use to rebuild if the view has children

Since:

1.5

See Also:

View.insertUpdate(javax.swing.event.DocumentEvent, java.awt.Shape, javax.swing.text.ViewFactory)

removeUpdate

public void removeUpdate(DocumentEvent e,
                         Shape a,
                         ViewFactory f)

Gives notification that something was removed from the document in a location that this view is responsible for. If either parameter is null, behavior of this method is implementation dependent.

Overrides:

removeUpdate in class GlyphView

Parameters:

e - the change information from the associated document

a - the current allocation of the view

f - the factory to use to rebuild if the view has children

Since:

1.5

See Also:

View.removeUpdate(javax.swing.event.DocumentEvent, java.awt.Shape, javax.swing.text.ViewFactory)

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.

Overrides:

changedUpdate in class LabelView

Parameters:

e - the change information from the associated document

a - the current allocation of the view

f - the factory to use to rebuild if the view has children

See Also:

View.changedUpdate(javax.swing.event.DocumentEvent, java.awt.Shape, javax.swing.text.ViewFactory)

getAttributes

public AttributeSet getAttributes()

Fetches the attributes to use when rendering. This is implemented to multiplex the attributes specified in the model with a StyleSheet.

Overrides:

getAttributes in class View

getBreakWeight

public int getBreakWeight(int axis,
                          float pos,
                          float len)

Determines how attractive a break opportunity in this view is. This can be used for determining which view is the most attractive to call breakView on in the process of formatting. A view that represents text that has whitespace in it might be more attractive than a view that has no whitespace, for example. The higher the weight, the more attractive the break. A value equal to or lower than BadBreakWeight should not be considered for a break. A value greater than or equal to ForcedBreakWeight should be broken.

This is implemented to provide the default behavior of returning BadBreakWeight unless the length is greater than the length of the view in which case the entire view represents the fragment. Unless a view has been written to support breaking behavior, it is not attractive to try and break the view. An example of a view that does support breaking is LabelView. An example of a view that uses break weight is ParagraphView.

Overrides:

getBreakWeight in class GlyphView

Parameters:

axis - may be either View.X_AXIS or View.Y_AXIS

pos - the potential location of the start of the broken view >= 0. This may be useful for calculating tab positions.

len - specifies the relative length from pos where a potential break is desired >= 0.

Returns:

the weight, which should be a value between ForcedBreakWeight and BadBreakWeight.

See Also:

LabelView, ParagraphView, View.BadBreakWeight, View.GoodBreakWeight, View.ExcellentBreakWeight, View.ForcedBreakWeight

breakView

public View breakView(int axis,
                      int offset,
                      float pos,
                      float len)

Tries to break this view on the given axis. Refer to View.breakView(int, int, float, float) for a complete description of this method.

Behavior of this method is unspecified in case axis is neither View.X_AXIS nor View.Y_AXIS, and in case offset, pos, or len is null.

Overrides:

breakView in class GlyphView

Parameters:

axis - may be either View.X_AXIS or View.Y_AXIS

offset - the location in the document model that a broken fragment would occupy >= 0. This would be the starting offset of the fragment returned

pos - the position along the axis that the broken view would occupy >= 0. This may be useful for things like tab calculations

len - specifies the distance along the axis where a potential break is desired >= 0

Returns:

the fragment of the view that represents the given span.

Since:

1.5

View.breakView(int, int, float, float)

setPropertiesFromAttributes

protected void setPropertiesFromAttributes()

Set the cached properties from the attributes.

Overrides:

setPropertiesFromAttributes in class LabelView

getStyleSheet

protected StyleSheet getStyleSheet()
