| Methods Summary |
|---|
| public javax.swing.text.View | breakView(int axis, int offset, float pos, float len)
return null;
|
| public void | changedUpdate(javax.swing.event.DocumentEvent changes, java.awt.Shape a, javax.swing.text.ViewFactory f)
super.changedUpdate(changes, a, f);
int pos = changes.getOffset();
if (pos <= getStartOffset() && (pos + changes.getLength()) >=
getEndOffset()) {
setPropertiesFromAttributes();
}
|
| public javax.swing.text.AttributeSet | getAttributes()Fetches the attributes to use when rendering. This is
implemented to multiplex the attributes specified in the
model with a StyleSheet.
return attr;
|
| public int | getBreakWeight(int axis, float pos, float len)Determines how attractive a break opportunity in
this view is. This is implemented to request a forced break.
if (axis == X_AXIS) {
return ForcedBreakWeight;
}
return BadBreakWeight;
|
| private float | getLength(javax.swing.text.html.CSS$Attribute key, javax.swing.text.AttributeSet a)
CSS.LengthValue lv = (CSS.LengthValue) a.getAttribute(key);
float len = (lv != null) ? lv.getValue() : 0;
return len;
|
| public float | getPreferredSpan(int axis)Calculates the desired shape of the rule... this is
basically the preferred size of the border.
switch (axis) {
case View.X_AXIS:
return 1;
case View.Y_AXIS:
if (size > 0) {
return size + SPACE_ABOVE + SPACE_BELOW + topMargin +
bottomMargin;
} else {
if (noshade != null) {
return 2 + SPACE_ABOVE + SPACE_BELOW + topMargin +
bottomMargin;
} else {
return SPACE_ABOVE + SPACE_BELOW + topMargin +bottomMargin;
}
}
default:
throw new IllegalArgumentException("Invalid axis: " + axis);
}
|
| public int | getResizeWeight(int axis)Gets the resize weight for the axis.
The rule is: rigid vertically and flexible horizontally.
if (axis == View.X_AXIS) {
return 1;
} else if (axis == View.Y_AXIS) {
return 0;
} else {
return 0;
}
|
| public java.awt.Shape | modelToView(int pos, java.awt.Shape a, javax.swing.text.Position$Bias b)Provides a mapping from the document model coordinate space
to the coordinate space of the view mapped to it.
int p0 = getStartOffset();
int p1 = getEndOffset();
if ((pos >= p0) && (pos <= p1)) {
Rectangle r = a.getBounds();

r.x += r.width;
}

}
return null;

|
| public int | viewToModel(float x, float y, java.awt.Shape a, javax.swing.text.Position$Bias[] bias)Provides a mapping from the view coordinate space to the logical
coordinate space of the model.
Rectangle alloc = (Rectangle) a;
if (x < alloc.x + (alloc.width / 2)) {
bias[0] = Position.Bias.Forward;
return getStartOffset();
}
