public void | changedUpdate(javax.swing.event.DocumentEvent e, java.awt.Shape a, javax.swing.text.ViewFactory f)Gives notification from the document that attributes were changed
in a location that this view is responsible for. Currently this view
handles changes to its SRC attribute.
Element elem = getElement();
AttributeSet attributes = elem.getAttributes();
URL oldPage = src;
String srcAtt = (String)attributes.getAttribute(HTML.Attribute.SRC);
URL base = ((HTMLDocument)elem.getDocument()).getBase();
try {
src = new URL(base, srcAtt);
if (!createdComponent) {
return;
}
if (oldPage.equals(src) && (src.getRef() == null)) {
return;
}
htmlPane.setPage(src);
Document newDoc = htmlPane.getDocument();
if (newDoc instanceof HTMLDocument) {
((HTMLDocument)newDoc).setFrameDocumentState(true);
}
} catch (MalformedURLException e1) {
// Need a way to handle exceptions
//e1.printStackTrace();
} catch (IOException e2) {
// Need a way to handle exceptions
//e2.printStackTrace();

|
private void | createScrollPane()This method creates the JScrollPane. The scrollbar policy is determined by
the scrolling attribute. If not defined, the default is "auto" which
maps to the scrollbar's being displayed as needed.
AttributeSet attributes = getElement().getAttributes();
String scrolling = (String)attributes.getAttribute(HTML.Attribute.SCROLLING);
if (scrolling == null) {
scrolling = "auto";
}
if (!scrolling.equals("no")) {
if (scrolling.equals("yes")) {

JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
} else {
// scrollbars will be displayed if needed
//
scroller = new JScrollPane();
}
} else {

}
JViewport vp = scroller.getViewport();
vp.add(htmlPane);
vp.setBackingStoreEnabled(true);
scroller.setMinimumSize(new Dimension(5,5));
scroller.setMaximumSize(new Dimension(Integer.MAX_VALUE, Integer.MAX_VALUE));

javax.swing.JEditorPane | getHostPane()
Container c = getContainer();
while ((c != null) && ! (c instanceof JEditorPane)) {
c = c.getParent();
}
return (JEditorPane) c;
|
public float | getMaximumSpan(int axis)Determines the maximum span for this view along an
axis.
return Integer.MAX_VALUE;
|
public float | getMinimumSpan(int axis)Determines the minimum span for this view along an
axis.
return 5;
|
private javax.swing.JEditorPane | getOutermostJEditorPane()Finds the outermost FrameSetView. It then
returns that FrameSetView's container.
View parent = getParent();
FrameSetView frameSetView = null;
while (parent != null) {
if (parent instanceof FrameSetView) {
frameSetView = (FrameSetView)parent;
}
parent = parent.getParent();
}
if (frameSetView != null) {
return (JEditorPane)frameSetView.getContainer();
}
return null;
|
public void | hyperlinkUpdate(javax.swing.event.HyperlinkEvent evt)Notification of a change relative to a
hyperlink. This method searches for the outermost
JEditorPane, and then fires an HTMLFrameHyperlinkEvent
to that frame. In addition, if the target is _parent,
and there is not nested framesets then the target is
reset to _top. If the target is _top, in addition to
firing the event to the outermost JEditorPane, this
method also invokes the setPage() method and explicitly
replaces the current document with the destination url.
JEditorPane c = getOutermostJEditorPane();
if (c == null) {
return;
}
if (!(evt instanceof HTMLFrameHyperlinkEvent)) {
c.fireHyperlinkUpdate(evt);
return;
}
HTMLFrameHyperlinkEvent e = (HTMLFrameHyperlinkEvent)evt;
if (e.getEventType() == HyperlinkEvent.EventType.ACTIVATED) {
String target = e.getTarget();
if (e.getTarget().equals("_parent") && !inNestedFrameSet()){
target = "_top";
}
if (evt instanceof FormSubmitEvent) {
HTMLEditorKit kit = (HTMLEditorKit)c.getEditorKit();
if (kit != null && kit.isAutoFormSubmission()) {
if (target.equals("_top")) {
try {
c.setPage(e.getURL());
} catch (IOException ex) {
// Need a way to handle exceptions
}
} else {
HTMLDocument doc = (HTMLDocument)c.getDocument();
doc.processHTMLFrameHyperlinkEvent(e);
}
} else {
c.fireHyperlinkUpdate(evt);
}
return;
}
if (target.equals("_top")) {
try {
c.setPage(e.getURL());
} catch (IOException ex) {
// Need a way to handle exceptions
// ex.printStackTrace();
}
}
if (!c.isEditable()) {
c.fireHyperlinkUpdate(new HTMLFrameHyperlinkEvent(c,
e.getEventType(),
e.getURL(),
e.getDescription(),
getElement(),
target));
}
}
|
private boolean | inNestedFrameSet()Returns true if this frame is contained within
a nested frameset.
FrameSetView parent = (FrameSetView)getParent();
return (parent.getParent() instanceof FrameSetView);
|
public void | paint(java.awt.Graphics g, java.awt.Shape allocation)Also determines if the FrameView should be editable
or not based on whether the JTextComponent that
contains it is editable. And then proceeds to call
the superclass to do the paint().
Container host = getContainer();
if (host != null && htmlPane != null &&
htmlPane.isEditable() != ((JTextComponent)host).isEditable()) {
editable = ((JTextComponent)host).isEditable();
htmlPane.setEditable(editable);
}
super.paint(g, allocation);
|
private void | setBorder()If the frameborder attribute has been specified, either in the frame,
or by the frames enclosing frameset, the JScrollPane's setBorder()
method is invoked to achieve the desired look.
AttributeSet attributes = getElement().getAttributes();
String frameBorder = (String)attributes.getAttribute(HTML.Attribute.FRAMEBORDER);
if ((frameBorder != null) &&
(frameBorder.equals("no") || frameBorder.equals("0"))) {
// make invisible borders.
scroller.setBorder(null);
}
|
private void | setMargin()If the marginwidth or marginheight attributes have been specified,
then the JEditorPane's margin's are set to the new values.
int margin = 0;
Insets in = htmlPane.getMargin();
Insets newInsets;
boolean modified = false;
AttributeSet attributes = getElement().getAttributes();
String marginStr = (String)attributes.getAttribute(HTML.Attribute.MARGINWIDTH);
if ( in != null) {
newInsets = new Insets(in.top, in.left, in.right, in.bottom);
} else {
newInsets = new Insets(0,0,0,0);
}
if (marginStr != null) {
margin = Integer.parseInt(marginStr);
if (margin > 0) {
newInsets.left = margin;
newInsets.right = margin;
modified = true;
}
}
marginStr = (String)attributes.getAttribute(HTML.Attribute.MARGINHEIGHT);
if (marginStr != null) {
margin = Integer.parseInt(marginStr);
if (margin > 0) {
newInsets.top = margin;
newInsets.bottom = margin;
modified = true;
}
}
if (modified) {
htmlPane.setMargin(newInsets);
}
|
public void | setParent(javax.swing.text.View parent)Sets the parent view for the FrameView.
Also determines if the FrameView should be editable
or not based on whether the JTextComponent that
contains it is editable.
if (parent != null) {
JTextComponent t = (JTextComponent)parent.getContainer();
editable = t.isEditable();
}
super.setParent(parent);
