Now I bounced in another little problem:
I studied the example for creating a checkbox:
http://itextdocs.lowagie.com/examples/com/lowagie/examples/forms/FormCheckbo
x.java
Is there a more simple way to create a default checkbox?
<>There is a class RadioCheckField:
RadioCheckField check = new RadioCheckField(writer, rect, name, "On");
check.setCheckType(RadioCheckField.TYPE_CROSS);
writer.addAnnotation(check.getCheckField());
But it only has a limited number of default appearances.
I really don't like
to draw the images for "checked" and "not checked". ;)
It's nothing to be afraid of ;-) I usually create an array with appearances
that I can reuse. For instance:
PdfAppearance[] onOff = new PdfAppearance[2];
onOff[0] = cb.createAppearance(20, 20);
onOff[0].rectangle(1, 1, 18, 18);
onOff[0].stroke();
onOff[1] = cb.createAppearance(20, 20);
onOff[1].setRGBColorFill(255, 128, 128);
onOff[1].rectangle(1, 1, 18, 18);
onOff[1].fillStroke();
onOff[1].moveTo(1, 1);
onOff[1].lineTo(19, 19);
onOff[1].moveTo(1, 19);
onOff[1].lineTo(19, 1);
onOff[1].stroke();
I reuse this array for every checkbox I need:
field.setWidget(rect, PdfAnnotation.HIGHLIGHT_INVERT);
field.setFieldName(name);
field.setValueAsName("Off");
field.setAppearanceState("Off");
field.setAppearance(PdfAnnotation.APPEARANCE_NORMAL, "Off", onOff[0]);
field.setAppearance(PdfAnnotation.APPEARANCE_NORMAL, "On", onOff[1]);
writer.addAnnotation(field);
