Hello,
I have seen a number of questions about RTE / wysiwyg editors, and I 'm in
need of one. I'am trying to integrate a trimmed down version of Mozilla
Midas wysiwyg to RAP.
I've almost archived what I need to do
1) Justification
2) Font family selection
3) Font properties (bold/italic/underlined)
4) Bullets and numbering
Although my implementation is not final, it gives me what I need for the
moment and might be of others help as well. And as always with the help of
others, we might have a working RTE.
So far I have arcihed to:
1) Display a document
2) Update the html any time
3) Get the html on focus out
So far my problems are:
1) (Major) Works in Firefox but focus out is not triggered on IE.
2) (Minor) Initially requires two clicks to focus
The final component should be able to
1) Send the damaged parts of the document rather then the whole document
2) Should support modifyText event
I would appreciate if someone with good js skills could have a look and
comment.
Below is the js code.
------------------------------------
qx.Class.define("org.eclipse.rwt.rte.RTE", {
extend : qx.ui.embed.Iframe,
construct : function(id) {
this.base(arguments);
this.setHtmlProperty("id", id);
this._id = id;
this.setSource("org/eclipse/rwt/rte/rte.html");
this._mainControl = null;
// Work around for late initialization of the content
qx.client.Timer.once(this._deferredInit, this, 100);
},
members : {
//static
_doActivate : function(obj) {
var shell = null;
var parent = obj.getParent();
while (shell == null && parent != null) {
if (parent.classname == "org.eclipse.swt.widgets.Shell") {
shell = parent;
}
parent = parent.getParent();
}
if (shell != null) {
shell.setActiveChild(obj);
}
},
//static
_sendModifyText : function(obj) {
alert(obj.getHtml());
var widgetManager = org.eclipse.swt.WidgetManager.getInstance();
var id = widgetManager.findIdByWidget(obj);
var req = org.eclipse.swt.Request.getInstance();
req.addParameter(id + ".html", obj.getHtml());
req.send();
},
setHtml : function(html) {
if (this._mainControl != null) {
this._mainControl.body.innerHTML = html;
}
},
getHtml : function() {
return this._mainControl.body.innerHTML;
},
// Work around for late initialization of the content
_deferredInit : function() {
if (this.getContentWindow() == null) {
qx.client.Timer.once(this._deferredInit, this, 100);
return;
}
_window = this.getContentDocument();
if (_window == null) {
qx.client.Timer.once(this._deferredInit, this, 200);
return;
}
_innerFrame = _window.getElementById("edit");
if (_innerFrame == null) {
qx.client.Timer.once(this._deferredInit, this, 200);
return;
}
this._mainControl = _innerFrame.contentWindow.document;
if (this._mainControl == null) {
qx.client.Timer.once(this._deferredInit, this, 200);
return;
}
if (this._mainControl.addEventListener) {
this._mainControl.addEventListener("blur", (function(obj) {
return function(event) {
obj._sendModifyText(obj);
}
})(this), true);
this._mainControl.addEventListener("focus", (function(obj) {
return function(event) {
obj._doActivate(obj);
}
})(this), true);
} else {
this._mainControl.attachEvent("blur", (function(obj) {
return function(event) {
obj._sendModifyText(obj);
}
})(this), true);
this._mainControl.attachEvent("focus", (function(obj) {
return function(event) {
obj._doActivate(obj);
}
})(this), true);
}
}
}
});
------------
The way it works is:
1) An iframe is initiated and the inner window is populated with a trimmed
down version of mozilla midas
2) A timer based initialization code tracks the existence of second inner
frame (created by midas) and as soon as available install focus and blur
listeners
3) On blur the html is sent to the server
4) On focus the focus is adjusted (from GMap example)

Hasan Ceylan

Hi Hasan,
to fix the problem "2) (Minor) Initially requires two clicks to focus)"
just call this.release(); of the IFrame when the content of the IFrame
is loaded. (you can do this on "load" event). This remove the blocker
div tag witch is on the top of the IFrame element :-). About problem "1)
(Major) Works in Firefox but focus out is not triggered on IE." - try
using qooxdoo API for adding/removig listeners from the DOM elements:
qx.html.EventRegistration.addEventListener( element, type, function )
qx.html.EventRegistration.removeEventListener( element, type, function )
In this case the browser specific code for event listeners will be held
by qooxdoo.
....and try to attach the listeners (focus/blur) to the document body
instead of document itself.
Best,
Ivan

Hi, I think that I've solved the two problems.
RTE.html:
function tbclick()
{
document.getElementById("edit").contentWindow.document.execCommand(this.id,
false, null);
document.getElementById("edit").contentWindow.focus();
}
RTE.js:
qx.Class.define("org.eclipse.rwt.rte.RTE", {
extend : qx.ui.embed.Iframe,
construct : function(id) {
this.base(arguments);
this.setHtmlProperty("id", id);
this._id = id;
this._html = "";
this._mainControl = null;
this._innerFrame = null;
this.setSource("org/eclipse/rwt/rte/rte.html");
qx.client.Timer.once(this._deferredInit, this, 100);
},
members : {
//static
_doActivate : function(obj) {
var shell = null;
var parent = obj.getParent();
while (shell == null && parent != null) {
if (parent.classname == "org.eclipse.swt.widgets.Shell") {
shell = parent;
}
parent = parent.getParent();
}
if (shell != null) {
shell.setActiveChild(obj);
}
},
//static
_sendModifyText : function(obj) {
var widgetManager = org.eclipse.swt.WidgetManager.getInstance();
var id = widgetManager.findIdByWidget(obj);
var req = org.eclipse.swt.Request.getInstance();
req.addParameter(id + ".html", obj.getHtml());
req.send();
},
setHtml : function(html) {
this._html = html;
if (this._mainControl != null) {
this._mainControl.body.innerHTML = html;
}
},
getHtml : function() {
return this._mainControl.body.innerHTML;
},
_onblur : function(obj){
this._sendModifyText(this);
},
_onfocus : function(obj){
this._doActivate(this);
},
_onload : function(obj){
this.release();
},
_deferredInit : function() {
if (this.getContentWindow() == null) {
qx.client.Timer.once(this._deferredInit, this, 100);
return;
}
_window = this.getContentDocument();
if (_window == null) {
qx.client.Timer.once(this._deferredInit, this, 200);
return;
}
_innerFrame = _window.getElementById("edit");
if (_innerFrame == null) {
qx.client.Timer.once(this._deferredInit, this, 200);
return;
}
this._mainControl = _innerFrame.contentWindow.document;
if (this._mainControl == null) {
qx.client.Timer.once(this._deferredInit, this, 200);
return;
}
this.setHtml(this._html);
qx.html.EventRegistration.addEventListener(this._mainControl , "blur",
qx.lang.Function.bind(this._onblur, this));
qx.html.EventRegistration.addEventListener(this._mainControl ,
"focus", qx.lang.Function.bind(this._onfocus, this));
qx.html.EventRegistration.addEventListener(_innerFrame.conte ntWindow,
"blur", qx.lang.Function.bind(this._onblur, this));
qx.html.EventRegistration.addEventListener(_innerFrame.conte ntWindow,
"focus", qx.lang.Function.bind(this._onfocus, this));
qx.html.EventRegistration.addEventListener(_innerFrame.conte ntWindow,
"load", qx.lang.Function.bind(this._onload, this));
}
}
});

Good news Jorge, I'll try your solution today.
