Hi Paulo,
I took a look at the PdfDocument code and modified the handling of
ListItems according to the Paragraph handling. It worked immediately!
Here's the patch ;-)
Best regards,
Christian
case Element.LISTITEM: {
// we cast the element to a ListItem
ListItem listItem = (ListItem) element;
float spacingBefore = listItem.spacingBefore();
if (spacingBefore != 0) {
leading = spacingBefore;
carriageReturn();
if (!pageEmpty) {
/*
* Don't add spacing before a paragraph if
it's the first
* on the page
*/
Chunk space = new Chunk(" ");
space.process(this);
carriageReturn();
}
}
// we adjust the document
alignment = listItem.alignment();
listIndentLeft += listItem.indentationLeft();
indentRight += listItem.indentationRight();
leading = listItem.leading();
carriageReturn();
// we prepare the current line to be able to show us
the listsymbol
line.setListItem(listItem);
// we process the item
element.process(this);
float spacingAfter = listItem.spacingAfter();
if (spacingAfter != 0) {
leading = spacingAfter;
carriageReturn();
if (currentHeight + line.height() + leading <
indentTop() - indentBottom()) {
/*
* Only add spacing after a paragraph if the
extra
* spacing fits on the page.
*/
Chunk space = new Chunk(" ");
space.process(this);
carriageReturn();
}
leading = listItem.leading(); // restore
original leading
}
// if the last line is justified, it should be
aligned to the left
// if (line.hasToBeJustified()) {
// line.resetAlignment();
// }
// some parameters are set back to normal again
carriageReturn();
listIndentLeft -= listItem.indentationLeft();
indentRight -= listItem.indentationRight();
break;
}
