Constructor Detail

JustifiableTextParagraphView

public JustifiableTextParagraphView(javax.swing.text.Element elem)

Create a JustifiableParagraphView for a paragraph element.

Parameters:

elem - The paragraph text element.

JustifiableTextFlowStrategy is used as the flow strategy. Each line of text in the paragraph is stored in a JustifiedTextRowView.

Method Detail

createRow

protected javax.swing.text.View createRow()

Create a JustifiedTextRowView to hold a a row's worth of children in a flow.

Overrides:

createRow in class javax.swing.text.ParagraphView

Returns:

The new JustifiedTextRowView.

getFlowSpan

public int getFlowSpan(int index)

Fetch the constraining span to flow against for the given child index.

Overrides:

getFlowSpan in class javax.swing.text.ParagraphView

Parameters:

index - The index of the view being queried.

Returns:

The constraining span for the given view at index.

layoutMinorAxis

protected void layoutMinorAxis(int targetSpan,
                               int axis,
                               int[] offsets,
                               int[] spans)

Perform layout for the minor axis of the box.

This is the same as the layout for a standard paragraph view except that we honor the first line indent attributed.

Overrides:

layoutMinorAxis in class javax.swing.text.BoxView

Parameters:

targetSpan - The total span given to the view, which should be used to layout the children.

axis - The axis being layed out.

offsets - The offsets from the origin of the view for each of the child views. This is a return value and is filled in here.

spans - The span of each child view. This is a return value and is filled in here.

The offset and span for each child view is stored in the offsets and spans parameters.
