XForms/Input Field Width< XForms
Sometimes you want to be able to control the field width, even though the default input text scrolls. This can be done for the entire form or for on a field-by-field basis for all input fields within a form. For example if you have three places that a person's last name occurs they can all be controlled by changing a single CSS file that is imported into the form. This CSS file can also be generated directly from an XML Schema or metadata registry using XML transforms.
<fieldset name="image_info" legend="Image Information">
<field name="subjectWeight" type="text" label="Subject Weight:" maxlength="10" size="15" /><label="Kg"> </filedset>
There are many tradeoffs as to where to put form width information. Ideally it would be generated by a script from a metadata registry. One of the questions concerns if a data element length should only have a default recommended value in a semantic registry and the actual constraints be stored in a constraint schema. We all know that zip codes should be 5 or 9 digits and that a 12 digit zip code may only have meaning in a specific context.
This example has been tested using the FireFox browser. The use of the .xf-value class selector may not work on other systems.
