Hi JC21!

Please have a look in the online reference at

the SetFormField...-calls.

With the current version it's not possible to create Dropdown-elements.

These are the possible styles with NewFormField:

1 = Text
2 = Pushbutton
3 = Checkbox
4 = Radiobutton
5 = Choice
6 = Signature
7 = Parent

Cheers and welcome here,

Ingo

Ingo, in searching on the subject matter more...awhile back you posted on another thread

"You should try the official support pages for this.
Textcontent is very easy ... other formfields is heavy stuff!"

where is the official support page? I need to be able to set the values of a choice field dynamically through code....

Hi, even we need to read and set values of a choice field/drop downl list. I older versions it used to work but unfortunatly it seems to be broken in the current version!

Hi!

Here's a kb-article from Rowan how to read values from radiobuttons:

Try the knowledgebase of QuickPDF searching with "choice" and "radio button":

Quick PDF Library creates and manages form fields of Choice type,

so they can be properly rendered with other PDF viewers.

But there is known issue in Quick PDF that is connected with rendering Choice form fields.

It is already fixed and is going to be added to the nearest release.

Let me provide a code sample that may help to create and manage Choice form fields:

var
f: Integer;

QPL: TQuickPDF;

begin

// Create QPL instance here and may be load some PDF file...
with QPL do
begin
    f := NewFormField('Choice1', 5);
    AddFormFieldSub(f, ' - one');
    AddFormFieldSub(f, ' - two');
    AddFormFieldSub(f, ' - three');
    SetOrigin(1);
    SetFormFieldBounds(f, 50, 50, 150, 30);
    SetFormFieldBackgroundColor(f, 0.5, 1, 0.5);

    // Here subitem with subindex=2 is selected
    SetFormFieldValue(f, GetFormFieldSubName(f, 2));
    UpdateAppearanceStream(f);
end;

end;

-------------
Regards,
Dmitry
