             Summary: Propose to add new API to insert form controls into 
document
                 Key: ODFTOOLKIT-340
                 URL: https://issues.apache.org/jira/browse/ODFTOOLKIT-340
             Project: ODF Toolkit
          Issue Type: New Feature
          Components: simple api
    Affects Versions: 0.7
            Reporter: Kejia Ye
             Fix For: 0.8


Here's a customer requirement that new APIs are needed to insert standard from 
controls into document, like Radio buttons, Checkboxes and InputFields. 
Additionally, it is required to assign appropriate labels and values to the 
inserted controls.

To support this feature, a problem came up first.  A form control is 
implementation-dependent and it may have self-defined attributes that cannot be 
ignored and auto-generated by editors. Besides, not all the forms defined in 
the ODF specs are fully supported by common ODF editors.For example, AOO use 
<form:formatted-text> to implement date field and time field.

I think one way to resolve this can be separating the implementation-dependent 
details from other contents. Define a provider class which implements Form 
interface and provide methods to create controls, like 
provider.createTextArea(initValues). For now we can only use OOFormProvider as 
the default one and use its implementation methods to initiate the controls, 
but user can also define customized providers by themselves.

Besides, how to define the style of a shape and set anchor type of a control to 
char may be also complex. I'll try to figure them out as I dig into the details.

Any one have comments or ideas with this proposal? Thanks!
