| Constructor Summary | |
| public | BlockView(Element elem, int axis)
Creates a new view that represents an
html box. |
| Method Summary | |
| protected SizeRequirements | calculateMajorAxisRequirements(int axis, SizeRequirements r)
Calculate the requirements of the block along the major
axis (i.e. | | protected SizeRequirements | calculateMinorAxisRequirements(int axis, SizeRequirements r)
Calculate the requirements of the block along the minor
axis (i.e. | | public void | changedUpdate(DocumentEvent changes, Shape a, ViewFactory f)
| | public float | getAlignment(int axis)
Gets the alignment. | | public AttributeSet | getAttributes()
Fetches the attributes to use when rendering. | | public float | getMaximumSpan(int axis)
Determines the maximum span for this view along an
axis. | | public float | getMinimumSpan(int axis)
Determines the minimum span for this view along an
axis. | | public float | getPreferredSpan(int axis)
Determines the preferred span for this view along an
axis. | | public int | getResizeWeight(int axis)
Gets the resize weight. | | protected StyleSheet | getStyleSheet()
| | boolean | isPercentage(int axis, AttributeSet a)
| | protected void | layoutMinorAxis(int targetSpan, int axis, int[] offsets, int[] spans)
Performs layout for the minor axis of the box (i.e. | | public void | paint(Graphics g, Shape allocation)
Renders using the given rendering surface and area on that
surface. | | public void | setParent(View parent)
Establishes the parent view for this view. | | protected void | setPropertiesFromAttributes()
Update any cached values that come from attributes. | | static boolean | spanSetFromAttributes(int axis, SizeRequirements r, CSS.LengthValue cssWidth, CSS.LengthValue cssHeight)
Adjust the given requirements to the CSS width or height if
it is specified along the applicable axis. |
| BlockView | | public BlockView(Element elem, int axis)(Code) | | Creates a new view that represents an
html box. This can be used for a number
of elements.
Parameters:
elem - the element to create a view for
Parameters:
axis - either View.X_AXIS or View.Y_AXIS |
| calculateMajorAxisRequirements | | protected SizeRequirements calculateMajorAxisRequirements(int axis, SizeRequirements r)(Code) | | Calculate the requirements of the block along the major
axis (i.e. the axis along with it tiles). This is implemented
to provide the superclass behavior and then adjust it if the
CSS width or height attribute is specified and applicable to
the axis.
|
| calculateMinorAxisRequirements | | protected SizeRequirements calculateMinorAxisRequirements(int axis, SizeRequirements r)(Code) | | Calculate the requirements of the block along the minor
axis (i.e. the axis orthoginal to the axis along with it tiles).
This is implemented
to provide the superclass behavior and then adjust it if the
CSS width or height attribute is specified and applicable to
the axis.
|
| getAlignment | | public float getAlignment(int axis)(Code) | | Gets the alignment.
Parameters:
axis - may be either X_AXIS or Y_AXIS the alignment |
| getAttributes | | public AttributeSet getAttributes()(Code) | | Fetches the attributes to use when rendering. This is
implemented to multiplex the attributes specified in the
model with a StyleSheet.
|
| getMaximumSpan | | public float getMaximumSpan(int axis)(Code) | | Determines the maximum span for this view along an
axis.
Parameters:
axis - may be either View.X_AXISor View.Y_AXIS the span the view would like to be rendered into >= 0;typically the view is told to render into the spanthat is returned, although there is no guarantee; the parent may choose to resize or break the view
exception:
IllegalArgumentException - for an invalid axis type |
| getMinimumSpan | | public float getMinimumSpan(int axis)(Code) | | Determines the minimum span for this view along an
axis.
Parameters:
axis - may be either View.X_AXISor View.Y_AXIS the span the view would like to be rendered into >= 0;typically the view is told to render into the spanthat is returned, although there is no guarantee; the parent may choose to resize or break the view
exception:
IllegalArgumentException - for an invalid axis type |
| getPreferredSpan | | public float getPreferredSpan(int axis)(Code) | | Determines the preferred span for this view along an
axis.
Parameters:
axis - may be either View.X_AXISor View.Y_AXIS the span the view would like to be rendered into >= 0;typically the view is told to render into the spanthat is returned, although there is no guarantee; the parent may choose to resize or break the view
exception:
IllegalArgumentException - for an invalid axis type |
| getResizeWeight | | public int getResizeWeight(int axis)(Code) | | Gets the resize weight.
Parameters:
axis - may be either X_AXIS or Y_AXIS the weight
exception:
IllegalArgumentException - for an invalid axis |
| layoutMinorAxis | | protected void layoutMinorAxis(int targetSpan, int axis, int[] offsets, int[] spans)(Code) | | Performs layout for the minor axis of the box (i.e. the
axis orthoginal to the axis that it represents). The results
of the layout (the offset and span for each children) are
placed in the given arrays which represent the allocations to
the children along the minor axis.
Parameters:
targetSpan - the total span given to the view, whichwhould be used to layout the childre.
Parameters:
axis - the axis being layed out
Parameters:
offsets - the offsets from the origin of the view foreach of the child views; this is a return value and isfilled in by the implementation of this method
Parameters:
spans - the span of each child view; this is a returnvalue and is filled in by the implementation of this method |
| paint | | public void paint(Graphics g, Shape allocation)(Code) | | Renders using the given rendering surface and area on that
surface. This is implemented to delegate to the css box
painter to paint the border and background prior to the
interior.
Parameters:
g - the rendering surface to use
Parameters:
allocation - the allocated region to render into
See Also: View.paint |
| setParent | | public void setParent(View parent)(Code) | | Establishes the parent view for this view. This is
guaranteed to be called before any other methods if the
parent view is functioning properly.
This is implemented
to forward to the superclass as well as call the
BlockView.setPropertiesFromAttributes() method to set the paragraph properties from the css
attributes. The call is made at this time to ensure
the ability to resolve upward through the parents
view attributes.
Parameters:
parent - the new parent, or null if the view isbeing removed from a parent it was previously addedto |
| setPropertiesFromAttributes | | protected void setPropertiesFromAttributes()(Code) | | Update any cached values that come from attributes.
|
| spanSetFromAttributes | | static boolean spanSetFromAttributes(int axis, SizeRequirements r, CSS.LengthValue cssWidth, CSS.LengthValue cssHeight)(Code) | | Adjust the given requirements to the CSS width or height if
it is specified along the applicable axis. Return true if the
size is exactly specified, false if the span is not specified
in an attribute or the size specified is a percentage.
