Field Detail
INSETS_BOTTOM
final protected static int INSETS_BOTTOM(Code)
Bottom insets paint type.



INSETS_TOP
final protected static int INSETS_TOP(Code)
Top insets paint type.



MAIN_AREA
final protected static int MAIN_AREA(Code)
Main area paint type.



helperInd
protected int helperInd(Code)
Index of this view as child view in its parent. This gives the parent view a hint at which index it should search for this view. If this index is incorrect, the parent view searches the whole array of children. However this gives good optimization of child views search process.



insets
protected Insets insets(Code)
Border insets of this view. Can be null



packed
protected boolean packed(Code)
Is this view packed




Constructor Detail
BaseView
public BaseView(Element elem)(Code)
Construct new base view




Method Detail
displayHierarchy
public void displayHierarchy()(Code)
Display view hierarchy on console. Current view is marked with asterisk.



getAlignment
public float getAlignment(int axis)(Code)
Get aligment along an X_AXIS or Y_AXIS



getBaseX
abstract protected int getBaseX(int y)(Code)



getComponent
public JTextComponent getComponent()(Code)
Get component hosting this view.



getEditorUI
protected EditorUI getEditorUI()(Code)
Get editor UI



getHeight
abstract public int getHeight()(Code)
Get height of the view



getInsets
public Insets getInsets()(Code)
Get insets of this view.



getPaintAreas
abstract protected int getPaintAreas(Graphics g, int clipY, int clipHeight)(Code)
Returns binary composition of regions that should be painted. It can be binary composition of INSETS_TOP, MAIN_AREA and INSETS_BOTTOM.
Parameters:
  g - Graphics to paint through
Parameters:
  clip - clipping area of graphics object



getPosFromY
abstract protected int getPosFromY(int y)(Code)
Get position when knowing y-coord



getPreferredSpan
public float getPreferredSpan(int axis)(Code)
Get preferred span over axis



getStartY
protected int getStartY()(Code)
Get y base value for this view.



getViewStartY
abstract protected int getViewStartY(BaseView view, int helperInd)(Code)
Get child view's y base value. This function is called by children of this view to get its y offset.
Parameters:
  view - is child view of this view for which the offset should becomputed.
Parameters:
  helperInd - is index that child view has cached to ease the parent view tosearch for it in its children array. If this index is correct,parent uses it. If it's incorrect parent view searches throughthe whole array of its children to find the child. It thencalls children's setParentInd() to correct itslocation index.



getYFromPos
abstract protected int getYFromPos(int pos) throws BadLocationException(Code)
Get y-coord value from position



invalidateStartY
protected void invalidateStartY()(Code)
Informs the view that if it had cached start y of itself it should invalidate it as it is no longer valid and it should call getViewStartY() to get updated value.



isPacked
public boolean isPacked()(Code)
Getter for packed flag



modelToViewDG
abstract public void modelToViewDG(int pos, DrawGraphics dg) throws BadLocationException(Code)



paint
public void paint(Graphics g, Shape allocation)(Code)
It divides painting into three areas: INSETS_TOP, MAIN_AREA, INSETS_BOTTOM. It paints them sequentially using paintArea() method until it returns false. This implementation also supposes that allocation is instance of Rectangle to save object creations. The root view in TextUI implementation will take care to ensure child views will get rectangle instances.



paintAreas
abstract protected void paintAreas(Graphics g, int clipY, int clipHeight, int paintAreas)(Code)
Paint either top insets, main area, or bottom insets.
Parameters:
  g - Graphics to paint through
Parameters:
  clip - clipping area of graphics object
Parameters:
  paintAreas - binary composition of paint areas



setHelperInd
protected void setHelperInd(int ind)(Code)
This function is used to correct information about which index this child view occupies in parent view's array of children. It is called by parent view.



setPacked
public void setPacked(boolean packed)(Code)
Setter for packed flag



toString
public String toString()(Code)



updateMainHeight
abstract public void updateMainHeight()(Code)
Update height of main area as result of some important change. Propagate to child views if necessary.
