Hi David!
That would be great!
Please send your implementation!
I'm especially curious on how you managed to avoid the "browse" button.
Thanks allot!

I wish you a lot of luck but where you are going to hit the wall is
trying to get the file data into or out of the input tag, _javascript_
won't let you. The only way to get the file data from the input tag to
the server is to do a basic form submit. This is a security design
built into _javascript_. You can try to get around it but in my opinion,
after spending weeks on it, it's not possible.

Well the goal is to have a single widget which handles everything
needed.
Events are fired like "completed", "timeout", "failure" so the
interface is as simple as possible.
For the upload process itself I'm now trying to subclass
qx.io.remote.IframeTransport where everything seems to be ready
like form handling etc.
I'm adding now a file and an enctype property to the subclass and
creating an input tag of type file within the form.
If this works the rest should be simple.
Well lets see what happens.

Why would you use qooxdoo-widgets for this? I think it's easier
to create a form with DOM-api(createElement, createTextNode,
createAttribute...). But i haven't tried such a thing yet.
Thank you Alex but it would be sufficient to use the usual file
selector which pops up on normal upload form handling.
My current idea is to create a hidden iframe which includes a
form which includes an input of type file.
By inheriting qx.ui.form.TextField (qx.ui.form.FileField) which
shows the file select button.
With an associated valueChange eventhandler I can catch the
change of the FileField value and set the file field value of
within the iframe.
After that I can trigger the submit method of the iframe form
and catch the "load" event of the iframe which should indicate
the upload completion.
I just had a look at qx.io.remote.IframeTransport which also
creates a hidden iframe with form within but I don't know the
state of
implementation because the source has allot of TODO marks in it.

Do you have JVM on your client PCs? If yes then you can use
it(not really comfortable but anyway) to read files from hard
drive. ;-)
Hi Dietrich,
we did it in an other project, without useing qooxdoo, in the following
way. We create a div with style hidden, into the div we create a form
with the file field. From outside we fill the form with _javascript_ and
then post the form. For Securityreasons you could only use a
Fileselector from your browser it is not possible to write one on your
own in qooxdoo.

Hello List,
has anybody written code which does a file upload from within a qooxdoo
application and is willing to share it with the list?
I'd like to get an idea on how file uploading could be done.
Opening a native window which has a form which includes an input tag of
type file is the obvious method but that is not what the user wants.
Any help would be great.
Best regards...

hi
im doing since approximately one month a form implementation to qooxdoo!
i recently fnished a file-upload, which can combine with
qooxdoo-elements. This means you dont have a Browse-Button or Text-Input
Field, but a qooxdoo-button. I you wish i can send you an example.
At the moment i want to add a file upload progress bar to my
implementation, but im not ready yet.
