getStartOffset
public int getStartOffset()
- Overrides:
getStartOffset in class View
getEndOffset
public int getEndOffset()
- Overrides:
getEndOffset in class View
nextCollapsedFold
protected Fold nextCollapsedFold()
- Find next collapsed fold in the given offset range.
attachListeners
protected void attachListeners()
setParent
public void setParent(View parent)
- Description copied from class:
GapBoxView
- Sets the parent of the view.
The children are only initialized if someone
has previously asked for information
related to children (e.g.
getViewCount())
or for preferred, minimum or maximum span of this view.
- Overrides:
setParent in class GapDocumentView
- Parameters:
parent - the parent of the view, null if none
useCustomReloadChildren
protected boolean useCustomReloadChildren()
- Overrides:
useCustomReloadChildren in class GapBoxView
initCustomReloadChildren
protected void initCustomReloadChildren(FoldHierarchy hierarchy,
int startOffset,
int endOffset)
- Extra initialization for custom reload of children.
finishCustomReloadChildren
protected void finishCustomReloadChildren(FoldHierarchy hierarchy)
- Free any resources required for custom reload of children.
customReloadChildren
protected void customReloadChildren(int index,
int removeLength,
int startOffset,
int endOffset)
- Description copied from class:
GapBoxView
- Loads child views in a custom way.
- Overrides:
customReloadChildren in class GapBoxView
- Parameters:
index - index at which the views should be added/replaced.removeLength - number of removed children views. It is useful
when rebuilding children for a portion of the view.startOffset - starting offset from which the loading starts.endOffset - ending offset where the loading ends.
createCustomView
protected View createCustomView(ViewFactory f,
int startOffset,
int maxEndOffset,
int elementIndex)
- Description copied from class:
GapBoxView
- Create custom child view starting at
startOffset.
- Overrides:
createCustomView in class GapBoxView
- Parameters:
f - view factory to be used.startOffset - offset at which the created view must start.maxEndOffset - maximum ending offset to which the created view
may span.elementIndex - index of the child element that best represents
the startOffset. The element is child of the element that this view
is responsible for. If this view is not based by element then this
parameter will be -1.
foldHierarchyChanged
public void foldHierarchyChanged(FoldHierarchyEvent evt)
- Specified by:
foldHierarchyChanged in interface FoldHierarchyListener
paint
public void paint(Graphics g,
Shape allocation)
- Description copied from class:
GapBoxView
- Render the view using the given allocation and
rendering surface.
- Overrides:
paint in class GapDocumentView
- Parameters:
g - the rendering surface to useallocation - the allocated region to render into- See Also:
View.paint(java.awt.Graphics, java.awt.Shape)
setSize
public void setSize(float width,
float height)
- Description copied from class:
GapBoxView
- Sets the size of the view. This should cause
layout of the view if the view caches any layout
information.
The propagation of this operation to child views
can be done asynchronously if appropriate.
- Overrides:
setSize in class GapDocumentView
- Parameters:
width - the width >= 0height - the height >= 0
isChildrenResizeDisabled
protected boolean isChildrenResizeDisabled()
- Description copied from class:
GapBoxView
- Return true if the children should not be attempted to resize
once
setSize() is called on this view.
Turning this on may save considerable time but it should be only
used if the views truly do not react on setSize()
e.g. this should *not* be used if line-wrapping is turned on.
- Overrides:
isChildrenResizeDisabled in class GapBoxView
propertyChange
public void propertyChange(PropertyChangeEvent evt)
- Specified by:
propertyChange in interface PropertyChangeListener
getYFromPos
public int getYFromPos(int offset,
Shape a)
