How to Change CheckBox Icon from Checkmark to Cross SOLVED

[RudiRo]

Hi,

I'm trying to create a new Pdf Document with some FormFields.
The Default Checkbox Icon Displayed in my Document is a Checkmark.

Is it possible to change the Icon to a Cross instead ? In the Editor a Option is given.

Code to Create CheckBox:

var ff = m_Document.AcroForm.CreateField("AB", PXC_FormFieldType.FFT_CheckBox, currentPage, mediaBox);
ff.CheckWidget(0, true);

Creation of the CheckBox works fine, i just need a hint where i could find the Option to Change the IconStyle.
For TextFields Color and FontSize could be set with the Interface "IPXC_AnnotData_Widget" , but can't find a suitable Interface / Method for Changing the Icon.

Thank you
Rudi

Hi Rudiro,

You can determine that option in the properties pane for selected check boxes, in the CheckBox Style property dropdown menu, where a range of options are available, including the 'cross' option which you requested:

Kind regards,

Hi Sean,

Thank you very much, but im looking for a option to achieve this style, in the Creation of the Checkbox in my C# Code.

Sample Code for Visualisation:

PXV_Inst m_PdfInst = new PXV_Inst();
IPXC_Document m_Document = m_PdfInst.NewCoreDoc();
var mediaBox = new PXC_Rect();
mediaBox.top = m_PageHeight;
mediaBox.right = m_PageWidth;
mediaBox.left = 0;
mediaBox.bottom = 0;
m_Document.Pages.AddEmptyPages(0, 1, mediaBox, null, out undoData);
uint currentPage = m_Document.Pages.Count - 1;
var mediaBox = new PXC_Rect();
mediaBox.top = m_PageHeight - 20;
mediaBox.bottom = m_PageHeight - 40;
mediaBox.left = 220;
mediaBox.right = 240;

var ff = m_Document.AcroForm.CreateField("AB", PXC_FormFieldType.FFT_CheckBox, currentPage, mediaBox);
ff.CheckWidget(0, true);

And here im looking for the Option to Change the Icon of my created CheckBox

IAFS_Inst fsInst = (IAFS_Inst)m_PdfInst.GetExtension("AFS");
IAFS_Name destPath = fsInst.DefaultFileSys.StringToName(fileName);
m_Document.WriteTo(destPath);

Thank you
Rudi

Hello Rudi,

Thanks for the additional details.
I've asked a colleague from the dev team who works on the JS engine to take a look, and will post further info here in this topic once I've received their feedback.

Kind regards,
Stefan

CheckBox 'icon' is set using the Content property of the corresponding widget. Just use the IPXC_AnnotData_Widget interface as you did for setting up font size and color, but now use the Content property.
It should have the following value:
"4" - for check-mark
"l" - (small letter L) - for circle
"8" - cross
"u" - diamond
"n" - square
"H" - star

That's because for rendering the icon, one of the standard built-in PDF fonts - ZapfDingbats - is used. Technically, you can use any of its characters as an icon. I attached screenshots from the PDF specification with its characters set. Please note, values in the "Code" columns are octal.

P.S. In the case of the cross ("8") font is not used.

Hello Ivan,

Thank you for the explanation.
Sadly i can't seem to get it to work.

I get the IPXC_AnnotData_Widget interface from my created FormField.

var ff = m_Document.AcroForm.CreateField("AB", PXC_FormFieldType.FFT_CheckBox, currentPage, mediaBox);
IPXC_Annotation widget = ff.Widget[0];
IPXC_AnnotData aData = widget.Data;
IPXC_AnnotData_Widget aWData = (IPXC_AnnotData_Widget)aData;

The aWData.Contents Property returns an Empty String("")

Setting it to another value and returning it to the widget has no effect.

aWData.Contents = "8";
widget.Data = aWData;

Am i misinterpreting the "Content" property ?

I can't find a Property in aWData with a Default Value of "4" for the Default Checkmark.

Thanks in Advance
Rudi

Sorry, my bad, I mislead you a little bit.
Instead of using aWData.Contents = "8", please use

Code: Select all

aWData.SetCaption(AAT_Normal, "8", true)
