javax.swing.text.ParagraphView
View of a simple line-wrapping paragraph that supports multiple fonts, colors, components, icons, etc. It is basically a vertical box with a margin around it. The contents of the box are a bunch of rows which are special horizontal boxes. This view creates a collection of views that represent the child elements of the paragraph element. Each of these views are placed into a row directly if they will fit, otherwise the breakView method is called to try and carve the view into pieces that fit.

->paragraph-viewclj
(->paragraph-view elem)Constructor.
Constructs a ParagraphView for the given element.
elem - the element that this view is responsible for - javax.swing.text.Element
Constructor. Constructs a ParagraphView for the given element. elem - the element that this view is responsible for - `javax.swing.text.Element`
break-viewclj
(break-view this axis len a)Breaks this view on the given axis at the given length.
ParagraphView instances are breakable along the Y_AXIS only, and only if len is after the first line.
axis - may be either View.X_AXIS or View.Y_AXIS - int
len - specifies where a potential break is desired along the given axis >= 0 - float
a - the current allocation of the view - java.awt.Shape
returns: the fragment of the view that represents the
given span, if the view can be broken; if the view
doesn't support breaking behavior, the view itself is
returned - javax.swing.text.View
Breaks this view on the given axis at the given length. ParagraphView instances are breakable along the Y_AXIS only, and only if len is after the first line. axis - may be either View.X_AXIS or View.Y_AXIS - `int` len - specifies where a potential break is desired along the given axis >= 0 - `float` a - the current allocation of the view - `java.awt.Shape` returns: the fragment of the view that represents the given span, if the view can be broken; if the view doesn't support breaking behavior, the view itself is returned - `javax.swing.text.View`
changed-updateclj
(changed-update this changes a f)Gives notification from the document that attributes were changed in a location that this view is responsible for.
changes - the change information from the associated document - javax.swing.event.DocumentEvent
a - the current allocation of the view - java.awt.Shape
f - the factory to use to rebuild if the view has children - javax.swing.text.ViewFactory
Gives notification from the document that attributes were changed in a location that this view is responsible for. changes - the change information from the associated document - `javax.swing.event.DocumentEvent` a - the current allocation of the view - `java.awt.Shape` f - the factory to use to rebuild if the view has children - `javax.swing.text.ViewFactory`
get-alignmentclj
(get-alignment this axis)Determines the desired alignment for this view along an axis. This is implemented to give the alignment to the center of the first row along the y axis, and the default along the x axis.
axis - may be either View.X_AXIS or View.Y_AXIS - int
returns: the desired alignment. This should be a value
between 0.0 and 1.0 inclusive, where 0 indicates alignment at the
origin and 1.0 indicates alignment to the full span
away from the origin. An alignment of 0.5 would be the
center of the view. - float
Determines the desired alignment for this view along an axis. This is implemented to give the alignment to the center of the first row along the y axis, and the default along the x axis. axis - may be either View.X_AXIS or View.Y_AXIS - `int` returns: the desired alignment. This should be a value between 0.0 and 1.0 inclusive, where 0 indicates alignment at the origin and 1.0 indicates alignment to the full span away from the origin. An alignment of 0.5 would be the center of the view. - `float`
get-break-weightclj
(get-break-weight this axis len)Gets the break weight for a given location.
ParagraphView instances are breakable along the Y_AXIS only, and only if len is after the first row. If the length is less than one row, a value of BadBreakWeight is returned.
axis - may be either View.X_AXIS or View.Y_AXIS - int
len - specifies where a potential break is desired >= 0 - float
returns: a value indicating the attractiveness of breaking here;
either GoodBreakWeight or BadBreakWeight - int
Gets the break weight for a given location. ParagraphView instances are breakable along the Y_AXIS only, and only if len is after the first row. If the length is less than one row, a value of BadBreakWeight is returned. axis - may be either View.X_AXIS or View.Y_AXIS - `int` len - specifies where a potential break is desired >= 0 - `float` returns: a value indicating the attractiveness of breaking here; either GoodBreakWeight or BadBreakWeight - `int`
get-flow-spanclj
(get-flow-span this index)Fetches the constraining span to flow against for the given child index.
index - the index of the view being queried - int
returns: the constraining span for the given view at
index - int
Fetches the constraining span to flow against for the given child index. index - the index of the view being queried - `int` returns: the constraining span for the given view at index - `int`
get-flow-startclj
(get-flow-start this index)Fetches the location along the flow axis that the flow span will start at.
index - the index of the view being queried - int
returns: the location for the given view at
index - int
Fetches the location along the flow axis that the flow span will start at. index - the index of the view being queried - `int` returns: the location for the given view at index - `int`
next-tab-stopclj
(next-tab-stop this x tab-offset)Returns the next tab stop position given a reference position. This view implements the tab coordinate system, and calls getTabbedSpan on the logical children in the process of layout to determine the desired span of the children. The logical children can delegate their tab expansion upward to the paragraph which knows how to expand tabs. LabelView is an example of a view that delegates its tab expansion needs upward to the paragraph.
This is implemented to try and locate a TabSet in the paragraph element's attribute set. If one can be found, its settings will be used, otherwise a default expansion will be provided. The base location for for tab expansion is the left inset from the paragraphs most recent allocation (which is what the layout of the children is based upon).
x - the X reference position - float
tab-offset - the position within the text stream that the tab occurred at >= 0 - int
returns: the trailing end of the tab expansion >= 0 - float
Returns the next tab stop position given a reference position.

paintclj
(paint this g a)Renders using the given rendering surface and area on that surface. This is implemented to delegate to the superclass after stashing the base coordinate for tab calculations.
g - the rendering surface to use - java.awt.Graphics
a - the allocated region to render into - java.awt.Shape
Renders using the given rendering surface and area on that surface. This is implemented to delegate to the superclass after stashing the base coordinate for tab calculations. g - the rendering surface to use - `java.awt.Graphics` a - the allocated region to render into - `java.awt.Shape`
