Of course.
The snippet below is from the examples on your site.
It handles well wheel and arrow click events but not direct input in the
box.
Mhh, the example Spinner_1.html seems to work well here. Just tested
using IE6(XP) and Firefox 1.5.
Why do we have to write s3._manager.addEventHandler and not
s3.addEventHandler ? When I write only s3.addEventHandler, arrow clicks and
wheel events are not working any longer. (XP Pro/IE6/Firefox).
Event listeners shouldn't have any negative effect on the functioning of
qooxdoo widgets if they don't produce any errors.

window.application.main = function()
{
var d = this.getClientWindow().getClientDocument();
var s3 = new QxSpinner;
with(s3)
{
setLeft(180);
setTop(64);
setValue(0);
setMin(-3000);
setMax(3000);
};
d.add(s3);
d.add( (new QxLabel("3000").set({left:180, top:48})) );
d.add( (new QxLabel("-3000").set({left:180, top:90})) );
s3._manager.addEventListener("changeValue", function(e) {
alert("Value: " + e.getData());
});
};

Thank you for the quick reply !
QxSpinner is cool for what I wanted to do.
Now I have another problem. I looked at the demo examples on your site to
see how to attach a handler to a change of value (either directly in the
box
or with the wheel or with the arrows) and the code shows a "changeValue"
event but it doesn't seem to work. Can you help please ?
changeValue should work. Could you send us an small example which shows
the problem?
I know this would be much work but an event reference for each widget
would
be very helpful for newbies like me.
Yes this is true. We really need one. Any help is really appreciated in
this area. qooxdoo is just another open source product with the typical
problems ;)
Sebastian
Thank you,

Hi all,
Are there any documentation or examples about event handling, list of
available event for each class... ?
Basically I want a QSTextField to accept only int values, ie checking
that only numbers are being typed in and that there is no overflow. Is
there anything built-in to handle that or do I have to implement it
myself with event listeners ?
You can use a QxSpinner instead. It does also support ranges for integer
values.
Otherwise you need to implement it your own. Probably in a seperate
class which you can contribute to the community?
I used to write it very simply in standard javascript with a keypress
event handler returning false if last typed character was not a number
or if it throwed an overflow exception... How can you do it with QooXdoo
?
In my opinion keypress is general a bad idea to handle this stuff
because there are many actions like insert, cut, copy which you couldn't
handle with this method. In qooxdoo you have a "input" event which is
much more advanced than a simple keypress.
yourTextField.addEventListener("input", function(e) {
this.setValue(parseInt(this.getRuntimeValue()));
});
Hope this helps.
Sebastian
Thanks,
Laurent.
