Hi all,

what is the right procedure to place a multiline text form field? I tried in different ways without success.

ix = pdflib.NewFormField(pFieldName, cText) '--cText = 1
If ix <> 0 Then
pdflib.SetFormFieldTextFlags(ix, 1, 0, 0, 0, 0)
pdflib.SetFormFieldBounds(ix, m_left, m_top, m_width, m_height)
pdflib.SetFormFieldValue(ix, mVar) '--mVar = string text variable

End If

This way does not work. The text is placed but then get cut at the end of bound. My intention is to autowrap the text content assigned to it, without inserting Chr(13) or Chr(13)+chr(10) . Calculating the right position of each single chr(13) would be a mess.

Is it possible? Could you please post few line of code?

many thanks

Mimmo

Hi Skipper!

Try a search here (knowledgebase of QuickPDF) for an answer:
http://help.quickpdflibrary.com/search?q=FormField
You can download a demo-app-maker from the official supportpages to test a little bit with the settings:

Cheers and welcome here,

Hi Ingo,

many thanks for your reply and your welcome aboard. I agree with one of your customers that the suggested tools is a very valuable piece of software. It is the perfect complimentary tool for the help manual and for quick checking the still unknow functionalities of a such complex DLL.

I tested the sample code provided for the form fields and, with a quick modification, I got what I was asking for. I'll double check again my code because I don't see any difference between my code and the sample code. The only differences were the function call sequence and the text passed to the SetFormFieldValue() function. I'm using a variable, the sample use a constant text string. Changing both in the sample in order to replicate my code, I got the same expected result: the text wraps.

I'll let you know if my code still does not work.

Many thanks for now

Mimmo

Hi Mimmo,

Quick PDF Library contains essential functionality for form field text wrapping.

So if you need word wrapped or #13 wrapped form field text

please try this Delphi sample:

var
f: Integer;

begin
with QPL do
begin

// Create and unlock QPL here

    // . . .
    f := NewFormField('MultiText1', 1);
    SetOrigin(1);
    SetFormFieldBounds(f, 50, 50, 135, 80);
    SetFormFieldBackgroundColor(f, 0.8, 0.8, 1);
    SetFormFieldTextFlags(f, 1, 0, 0, 0, 0);
    SetFormFieldValue(1,
      'This text is wrapped using two basic types of wrapping: word wrap and #13 wrap' +
      #13 + 'Line 1...' + #13 + 'Line 2...' + #13 + 'Line 3...');

UpdateAppearanceStream(f);

SaveToFile('output.pdf');
end;

end;

If you still have some issues connected with form field text wrapping,

please link your problem PDF file and add detailed issue description.

Hi!

This is what Skipper has written:
"...

..."
He knows how to break lines. He thought that a multiline-field has an automatic word-wrapping included ;-)

Cheers, Ingo

Hi Ingo,

Well, multiline form field certainly has an automatic word-wrapping included :)

Just try attached code sample.
