Hi.
I am trying to use databinding with the rich text editor. I've managed
to make it work by simply returning an instance of
RichTextObservableValue the same way observeText returns
TextObservableValue. RichTextObservableValue is a class I've implemented
which inherites from AbstractVetoableValue. Everything is ok but I have
problems with the modify listener, that is, the ModifyEvent is not fired
when I write in the RichTextEditor, therefore my editor is not set as
dirty. To my surprise, this event is fired when pressing keys like
delete, back space... but not when I press simple characters. I don't
understand what is going on. Has anyone experienced anything similar?
Has anyone got to make databinding work with this editor?
Thanks in advance.
Mario

Hi Eric,
that's the class I'm using but the method modifyText is not invoked as
much as I'd like to. It's strange but it's invoked when I either use the
toolbar or press Del, back space... but not when I write simple
characters :S. The problem of this is that I have problems to set my
model as dirty. I could use the focus out event but the listener I use
doesn't get called either.

Are you trying it on Eclipse 3.4? I know our class works on 3.3 - we get
modify events as expected.

Hello
I'm using Eclipse 3.5.0 having the same problem, the ModifyListener is not
notified after text was tipped.
Was there any work done on this issue? Does a bug report exists? Should I
report one? Is there a workaround available?

hello
I kind of patched the "rte.js" and it kind of works now :-).
One strange behavior, the first key tip is not forwarded as modify event
and
some modify events will now probably be fired twice, but I don't care :-).
But here part of the org.eclipse.epf.richtext_1.5.0.x/rte/rte.js script:
var excludeModify = new Array(16, KEY_ARROW_DOWN, KEY_ARROW_LEFT,
KEY_ARROW_RIGHT, KEY_ARROW_UP, KEY_END, KEY_HOME, KEY_PAGE_DOWN,
KEY_PAGE_UP, KEY_TAB);
// Handles the key events.
function keyPressed(event) {
var keyCode = event.keyCode;
if (keyCode == 0 && !document.all) {
keyCode = event.charCode;
switch (keyCode) {
case 99:
keyCode = KEY_C;
break;
case 102:
keyCode = KEY_F;
break;
case 115:
keyCode = KEY_S;
break;
case 118:
keyCode = KEY_V;
break;
case 120:
keyCode = KEY_X;
break;
case 122:
keyCode = KEY_Z;
break;
}
}
var ctrlKey = event.ctrlKey;
var shiftKey = event.shiftKey;
var altKey = event.altKey;
if ( !ctrlKey && !altKey ) {
var modified = true;
for (var i = 0; i < excludeModify.length; i++ ) {
if ( keyCode == excludeModify[i] ) {
modified = false;
}
}
if ( modified == true ) {
setStatus(STATUS_MODIFIED, keyCode);
}
}
Maybe this can be a starting point to resolve this issue?
