you could create your own event with a special EventName (i.e.: "ExternalEvent"), register a QAjax(Control)Action with the method that handles your external events.

On the js side:

Thank you.
I almost got there but one question to go =)

'ExternalEvent' is what exactly I want to call the OnChange event?

Eg. this does not work:
qcubed.pA('InvoiceEditForm','c3','click','the_string_you_want_to_send_back');

It should call this test ClickEvent:
$this->txtButton1 = new QButton($this);
//$this->txtButton1->ControlId // = c3 I checked that
$this->txtButton1->AddAction(new QClickEvent(), new QToggleDisplayAction($this->TestpanelObject));

Thank you.

Using the following line should work with your example:

You have to use the class name of the event instead of the event name (my fault :))

the "ExternalEvent" was just an example you could create any event with any class name and event name.
But you have to register an event on a control or on the QForm and if it was no custom event it could be triggered (i.e.: a QClickEvent on a button control is not the best combination to use as a proxy :) ).

Example: create a custom event, register an ajax action for this event on QForm.

In your custom javascript you could use

Thank you. This is great.
It truly makes a lot of sense not to misuse a ClickEvent for the proxy. =)

However I have this now working with QClickEvent but it does not work yet with QExternalEvent.

Where do you suggest to put the code for the QExternalEvent class - is it suitable to be put in the same file as the EditForm (class InvoiceEditForm extends InvoiceEditFormBase)? Because this is where I tried it.

Another issue is that I have not realized how to get the actual value that was being sent. Can this be fetched with QApplication::QueryString('varname')?

Thanks again.

Best,

Sorry for the late reply.

@positioning of the derived event ... putting the code in the same file as the edit form should work.

@ return value: the last parameter of the "qc.pA" javascript method is returned to your ajax callback method as $strParameter

just define your callback method like this one:

if you use:

I think you can also find the value of your control in $_POST("mycontrolId")

Thank you that helped a lot!!
