Textbox maxlength attribute behavior

[majain]

In HTML, the maxlength attribute of a Textbox prevents user from typing texts greater than what is specified by maxlength attribute.

However, GXT's TextField.setMaxLength(...) method is used for max length validation only. It does not prevent user from typing texts greater than max length.

Is there any HTML maxlength equivalent attribute exist in GXT's TextField widget?

Thanks,
Majain

Anyone has idea on how to set the maxlength html (prevent user from typing more than the length specified) attribute on TextField widget?

There's probably some additional configuration you need to do if this is similar to ExtJS. Search ExtJS forums and you'll find something.

                fieldLabel: 'First Name',
                id: 'firstname',
                name: 'FirstName',

                //use autoCreate so the maxlength setting for form textfield and
                //numberfield components respected on onkeyup/onkeydown, rather
                //than just when the form is submitted.
                autoCreate : {
                    tag : 'input',
                    type : 'text',
                    name : 'FirstName',
                    //if don't specify this in autoCreate then just specifies size="6"
                    maxlength : 6
                },

Majain,

I have the same problem! Anyone have a suggest?
This is the basic function for a GUI framework.

Hello,

this is really easy to implement:

    TextField<String> text = new TextField() {

      @Override
      public void setMaxLength(int m) {
        super.setMaxLength(m);
        if (rendered) {
          getInputEl().setElementAttribute("maxLength", m);
        }
      }

      @Override
      protected void onRender(Element parent, int index) {
        super.onRender(parent, index);
        getInputEl().setElementAttribute("maxLength", getMaxLength());
      }
    };

Thanks for your quick response.

We have been using this code faithfully with our TextFields, but recently we've needed to implement this same logic with a text area and no matter what I try it doesn't work. Any quick solutions??
