Class FlowView.FlowStrategy
- FlowView
A strategy for translating the logical views of a FlowView
into the real views.
void | changedUpdate(FlowView fv, DocumentEvent e, Rectangle alloc) - Receives notification from a
FlowView that some attributes
have changed in the document at a location that the
FlowView is responsible for.
|
protected View | createView(FlowView fv, int offset, int spanLeft, int rowIndex) - Creates physical views that form the rows of the flow view.
|
View | getLogicalView(FlowView fv) - Returns the logical view of the managed
FlowView .
|
void | insertUpdate(FlowView fv, DocumentEvent e, Rectangle alloc) - Receives notification from a
FlowView that some content
has been inserted into the document at a location that the
FlowView is responsible for.
|
void | layout(FlowView fv) - Performs the layout for the whole view.
|
protected int | layoutRow(FlowView fv, int rowIndex, int pos) - Lays out one row of the flow view.
|
void | removeUpdate(FlowView fv, DocumentEvent e, Rectangle alloc) - Receives notification from a
FlowView that some content
has been removed from the document at a location that the
FlowView is responsible for.

FlowStrategy
public FlowStrategy()
Creates a new instance of FlowStragegy
.
changedUpdate
public void changedUpdate(FlowView fv,
DocumentEvent e,
Rectangle alloc)
Receives notification from a
FlowView
that some attributes
have changed in the document at a location that the
FlowView
is responsible for.
The default implementation simply calls
layout(FlowView)
.
fv
- the flow view that sends the notificatione
- the document event describing the changealloc
- the current allocation of the flow view
createView
protected View createView(FlowView fv,
int offset,
int spanLeft,
int rowIndex)
Creates physical views that form the rows of the flow view. This
can be an entire view from the logical view (if it fits within the
available span), a fragment of such a view (if it doesn't fit in the
available span and can be broken down) or null
(if it does
not fit in the available span and also cannot be broken down).
fv
- the flow viewoffset
- the start offset for the view to be createdspanLeft
- the available spanrowIndex
- the index of the row
- a view to fill the row with, or
null
if there
is no view or view fragment that fits in the available span
getLogicalView
public View getLogicalView(FlowView fv)
Returns the logical view of the managed FlowView
.
fv
- the flow view for which to return the logical view
- the logical view of the managed
FlowView
insertUpdate
public void insertUpdate(FlowView fv,
DocumentEvent e,
Rectangle alloc)
Receives notification from a
FlowView
that some content
has been inserted into the document at a location that the
FlowView
is responsible for.
The default implementation simply calls
layout(FlowView)
.
fv
- the flow view that sends the notificatione
- the document event describing the changealloc
- the current allocation of the flow view
layout
public void layout(FlowView fv)
Performs the layout for the whole view. By default this rebuilds
all the physical views from the logical views of the managed FlowView.
This is called by
FlowView.layout(int,int)
to update the layout of
the view.
fv
- the flow view for which we perform the layout
layoutRow
protected int layoutRow(FlowView fv,
int rowIndex,
int pos)
Lays out one row of the flow view. This is called by
layout(FlowView)
to fill one row with child views until the available span is exhausted.
fv
- the flow view for which we perform the layoutrowIndex
- the index of the rowpos
- the start position for the row
- the start position of the next row
removeUpdate
public void removeUpdate(FlowView fv,
DocumentEvent e,
Rectangle alloc)
Receives notification from a
FlowView
that some content
has been removed from the document at a location that the
FlowView
is responsible for.
The default implementation simply calls
layout(FlowView)
.
fv
- the flow view that sends the notificatione
- the document event describing the changealloc
- the current allocation of the flow view
