BlockView |
Creates a new view that represents an html box. |
Modifier and Type | Method | Description |
---|---|---|
protected SizeRequirements |
calculateMajorAxisRequirements |
Calculate the requirements of the block along the major axis (i.e. the axis along with it tiles). |
protected SizeRequirements |
calculateMinorAxisRequirements |
Calculate the requirements of the block along the minor axis (i.e. the axis orthogonal to the axis along with it tiles). |
float |
getAlignment |
Gets the alignment. |
AttributeSet |
getAttributes() |
Fetches the attributes to use when rendering. |
float |
getMaximumSpan |
Determines the maximum span for this view along an axis. |
float |
getMinimumSpan |
Determines the minimum span for this view along an axis. |
float |
getPreferredSpan |
Determines the preferred span for this view along an axis. |
int |
getResizeWeight |
Gets the resize weight. |
protected StyleSheet |
getStyleSheet() |
Convenient method to get the StyleSheet. |
protected void |
layoutMinorAxis |
Performs layout for the minor axis of the box (i.e. the axis orthogonal to the axis that it represents). |
void |
paint |
Renders using the given rendering surface and area on that surface. |
void |
setParent |
Establishes the parent view for this view. |
protected void |
setPropertiesFromAttributes() |
Update any cached values that come from attributes. |

public BlockView(Element elem, int axis)
elem
- the element to create a view foraxis
- either View.X_AXIS or View.Y_AXISpublic void setParent(View parent)
This is implemented to forward to the superclass as well as call the 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.
