QWebElement set and get attribute

2beers

Hi everyone. Just started playing with qt webkit and I'm facing a little problem. I started to modify this example: http://doc.qt.nokia.com/4.7/webkit-formextractor.html

and when I press a PushButton I want to change the value of an input html element and it works if I don't change manually the value from webkit widget. Do I need to make some refresh or something??

here is what I'm doing:

@void Form::submitInfo()
{
QWebFrame *frame = ui->webView->page()->mainFrame();

QWebElement firstName = frame->findFirstElement("#firstname");

firstName.setAttribute("value","some text");

}@

I do not understand the problem. Could you post a small example?

well on the HTML side I have something like this:
@<input tye="text" id="firstname" value="" />@

so when I press a QPushButton I want to change the value of this element to "some text"

I realized it works with something like this
@QWebFrame *frame = ui->webView->page()->mainFrame();

QWebElement firstName = frame->findFirstElement("#firstname");
firstName.evaluateJavaScript("this.value='some text' ").

@

but I'm interested if I can change the value without using javascript.

Thanks

You should not have to use JavaScript there. It could be a bug.

well it can change first time I pressed the QPushButton using
@ firstName.setAttribute("value","some text");@ but if I try to change the input text from the webkit widget and then press the QPushButton nothing happens.

Do you think I should submit the bug?

You can create a bug with http://webkit.org/new-qtwebkit-bug or post an example here. In both cases, you will have to make a reduction and I will review it so I do not mind which channel you use :)

here is a youtube video to see when the error appears: http://www.youtube.com/watch?v=2R63Me6CuI4

Wow, that is weird. Please create a bug, that does not look good at all.

not sure if it's in the right section but you can change that if you want: https://bugs.webkit.org/show_bug.cgi?id=53319
