| LeafView | | public class LeafView extends BaseView (Code) | | Leaf view implementation. This corresponds and requires leaf element to be
element for this view.
The view has the following structure:
+---------------------------------------------------------+ | insets.top area |
A | | | insets.top | | V |
+--------------------------------------------------+ | | | A | | | | | i | | | |
n | | | | s | | | | e | | | | t | | | | s | | | | . | | | | l | | | | e |
Main area of this view | | mainHeight | f | | | | t | | | | | | | | a | | | |
r | | | | e | | | | a | | | | | | | | | | | | | | | | | | | | | | V |
+--------------------------------------------------+ | insets.bottom area | A | | |
insets.bottom | | V

|
| modelToViewDG | | ModelToViewDG modelToViewDG(Code) | | Draw graphics for converting position to coords
|
| viewToModelDG | | ViewToModelDG viewToModelDG(Code) | | Draw graphics for converting coords to position
|
| LeafView | | public LeafView(Element elem)(Code) | | Construct new base view
|
| changedUpdate | | public void changedUpdate(DocumentEvent evt, Shape a, ViewFactory f)(Code) | | Attributes were changed in the are this view is responsible for.
Parameters:
e - the change information from the associated document
Parameters:
a - the current allocation of the view
Parameters:
f - the factory to use to rebuild if the view has children |
| getBaseX | | public int getBaseX(int y)(Code) | | |
| getHeight | | public int getHeight()(Code) | | Get total height of this view
|
| getPaintAreas | | protected int getPaintAreas(Graphics g, int clipY, int clipHeight)(Code) | | Returns binary composition of paint areas
|
| getPosFromY | | protected int getPosFromY(int y)(Code) | | Get begin of line position from y-coord. If the position is before main
area begining it returns start position. If it's beyond the end of view
it returns end position.
Parameters:
y - y-coord to inspect always returns startOffset for y < start ofmain area
Parameters:
eol - means to return end of specified line instead of begining position in the document |
| getView | | final public View getView(int n)(Code) | | Gets the n-th child view.
|
| getViewCount | | final public int getViewCount()(Code) | | Returns the number of child views in this view.
|
| getViewStartY | | protected int getViewStartY(BaseView view, int helperInd)(Code) | | Get child view's y base value. Invalid in this case.
|
| getYFromPos | | protected int getYFromPos(int pos) throws BadLocationException(Code) | | Get y coordinate from position. The position can lay anywhere inside this
view.
|
| insertUpdate | | public void insertUpdate(DocumentEvent evt, Shape a, ViewFactory f)(Code) | | Gives notification that something was inserted into the document in a
location that this view is responsible for.
Parameters:
e - the change information from the associated document
Parameters:
a - the current allocation of the view
Parameters:
f - the factory to use to rebuild if the view has children |
| paintAreas | | protected void paintAreas(Graphics g, int clipY, int clipHeight, int paintAreas)(Code) | | Paint either top insets, main area, or bottom insets depending on
paintAreas variable
|
| removeUpdate | | public void removeUpdate(DocumentEvent evt, Shape a, ViewFactory f)(Code) | | Gives notification from the document that attributes were removed in a
location that this view is responsible for.
Parameters:
e - the change information from the associated document
Parameters:
a - the current allocation of the view
Parameters:
f - the factory to use to rebuild if the view has children |
| updateMainHeight | | public void updateMainHeight()(Code) | | Compute and update main area height
|
