This class represents a form filler used for filling PDF form. There should be only one form filler object for an interactive form, so do not construct form filler for one FSForm object more than one time. User is recommended to implement an FSActionCallback and set it to Foxit PDF SDK by function FSLibrary::setActionCallback:, in order to implement more features of form filler.
- (void) highlightFormFields: | (BOOL) | is_highlight |
Decide whether to highlight form fields or not.
All types of form fields can be highlighted except push button fields. If this function is not called, Foxit PDF SDK will highlight all form fields by default.

- (void) render: | (FSPDFPage*) | page | |
matrix: | (FSMatrix2D*) | matrix | |
renderer: | (FSRenderer*) | renderer | |
Draw the currently focused form control on the page.
If there is no focused form control on the page, nothing will be drawn by this function. The focused form control has to be the topmost visible element, so that it should be always rendered after page content and all the other annotations have been rendered.
For how to render form control (which is associated with widget annotations), please refer to the recommended flow mentioned in comment of class Renderer.

- (BOOL) setFocus: | (FSControl*) | control |
Set focus on a form control.
[in] | control | A form control object. If this is constructed by default constructor and not set any value, that means no focus control. |
- (void) setHighlightColor: | (unsigned int) | color |
Set the highlight color used for highlighting form fields.
If this function is not called, Foxit PDF SDK will use a kind of light blue grey color (value 0x80C8D2FF) by default.
