    • getAttributes

      public AttributeSet getAttributes()
      Fetches the attributes to use when rendering. At the root level there are no attributes. If an attribute is resolved up the view hierarchy this is the end of the line.
      Overrides:
      getAttributes in class View
    • getPreferredSpan

      public float getPreferredSpan(int axis)
      Determines the preferred span for this view along an axis.
      Specified by:
      getPreferredSpan in class View
      Parameters:
      axis - may be either X_AXIS or Y_AXIS
      Returns:
      the span the view would like to be rendered into. Typically the view is told to render into the span that is returned, although there is no guarantee. The parent may choose to resize or break the view.
    • getMinimumSpan

      public float getMinimumSpan(int axis)
      Determines the minimum span for this view along an axis.
      Overrides:
      getMinimumSpan in class View
      Parameters:
      axis - may be either X_AXIS or Y_AXIS
      Returns:
      the span the view would like to be rendered into. Typically the view is told to render into the span that is returned, although there is no guarantee. The parent may choose to resize or break the view.
    • getMaximumSpan

      public float getMaximumSpan(int axis)
      Determines the maximum span for this view along an axis.
      Overrides:
      getMaximumSpan in class View
      Parameters:
      axis - may be either X_AXIS or Y_AXIS
      Returns:
      the span the view would like to be rendered into. Typically the view is told to render into the span that is returned, although there is no guarantee. The parent may choose to resize or break the view.
    • preferenceChanged

      public void preferenceChanged(View child, boolean width, boolean height)
      Specifies that a preference has changed. Child views can call this on the parent to indicate that the preference has changed. The root view routes this to invalidate on the hosting component.

      This can be called on a different thread from the event dispatching thread and is basically unsafe to propagate into the component. To make this safe, the operation is transferred over to the event dispatching thread for completion. It is a design goal that all view methods be safe to call without concern for concurrency, and this behavior helps make that true.

      Overrides:
      preferenceChanged in class View
      Parameters:
      child - the child view
      width - true if the width preference has changed
      height - true if the height preference has changed
    • getAlignment

      public float getAlignment(int axis)
      Determines the desired alignment for this view along an axis.
      Overrides:
      getAlignment in class View
      Parameters:
      axis - may be either X_AXIS or Y_AXIS
      Returns:
      the desired alignment, where 0.0 indicates the origin and 1.0 the full span away from the origin
    • paint

      public void paint(Graphics g, Shape allocation)
      Renders the view.
      Specified by:
      paint in class View

      g - the graphics context
      allocation - the region to render into
    • setParent

      public void setParent(View parent)
      Sets the view parent.
      Overrides:
      setParent in class View
      Parameters:
      parent - the parent view
    • getViewCount

      public int getViewCount()
      Returns the number of views in this view. Since this view simply wraps the root of the view hierarchy it has exactly one child.

      getViewCount in class View
      Returns:
      the number of views
      See Also:

      Gets the n-th view in this container.
      Overrides:
      getView in class View
      Parameters:
      n - the number of the view to get
      Returns:
      the view
    • modelToView

      public Shape modelToView(int pos, Shape a, Position.Bias b) throws BadLocationException

      Specified by:
      modelToView in class View
      Parameters:
      pos - the position to convert
      a - the allocated region to render into
      Returns:
      the bounding box of the given position

      BadLocationException
    • modelToView

      public Shape modelToView(int p0, Position.Bias b0, int p1, Position.Bias b1, Shape a) throws BadLocationException
      Provides a mapping from the document model coordinate space to the coordinate space of the view mapped to it.
      Overrides:
      modelToView in class View
      Parameters:
      p0 - the position to convert >= 0
      b0 - the bias toward the previous character or the next character represented by p0, in case the position is a boundary of two views.
