Hello Bruno!
Have done some modifications to PdfDocument.add(Element) again since I
noticed the following:
If a table has a header and a page is filled to such an extent that only the
header fits the page and the table needs to be continued on the next page ..
then (in case the property cellsFitPage is set to true) dont draw the header
in the remaining page area since anyways it will be repeated on next page!
Here is the modified code for the TABLE case (between G.F. start change and
G.F. end change) within the cell iterator loop:
boolean headerChecked = false;
for (ListIterator iterator = cells.listIterator(); iterator.hasNext()
&& !tableHasToFit;)
{
cell = (PdfCell) iterator.next();
// G.F. start change
if( cellsHaveToFit )
{
if( !cell.isHeader() ) // check as it has been done before
{
if (cell.rownumber() != currentRownumber)
{
boolean cellsFit = true;
currentRownumber = cell.rownumber();
int cellCount = 0;
while (cell.rownumber() == currentRownumber && cellsFit &&
iterator.hasNext())
{
if (cell.bottom() < indentBottom())
{
cellsFit = false;
}
cell = (PdfCell) iterator.next();
cellCount++;
}
if (!cellsFit)
{
break;
}
for (int i = cellCount; i >= 0; i--)
{
cell = (PdfCell) iterator.previous();
}
}
}
else
{
if( !headerChecked ) // check header once only
{
headerChecked = true;
boolean cellsFit = true;
int cellCount = 0;
float firstTop = cell.top();
// check if header cells fit page
while (cell.isHeader() && cellsFit && iterator.hasNext())
{
if (firstTop - cell.bottom(0) > indentTop() - currentHeight -
indentBottom())
{
cellsFit = false;
}
cell = (PdfCell) iterator.next();
cellCount++;
}
// check if at least one data line fits page
currentRownumber = cell.rownumber();
while (cell.rownumber() == currentRownumber && cellsFit &&
iterator.hasNext())
{
if (firstTop - cell.bottom(0) > indentTop() - currentHeight -
indentBottom() - 10.0)
{
cellsFit = false;
}
cell = (PdfCell) iterator.next();
cellCount++;
}
for (int i = cellCount; i >= 0; i--)
{
cell = (PdfCell) iterator.previous();
}
if (!cellsFit)
{
// remove header cells since will be drawn automatically in code
further down
while( cell.isHeader() )
{
iterator.remove();
cell = (PdfCell) iterator.next();
}
break;
}
}
}
// G.F. end change
}
lines = cell.getLines(pagetop, indentBottom());
// if there are lines to add, add them
if (lines != null && lines.size() > 0)
{
// we paint the borders of the cells
cellsShown = true;
cellGraphics.rectangle(cell.rectangle(pagetop, indentBottom()));
lostTableBottom = Math.max(cell.bottom(), indentBottom());
// we write the text
float cellTop = cell.top(pagetop - oldHeight);
text.moveText(0, cellTop);
cellDisplacement = flushLines() - cellTop;
text.moveText(0, cellDisplacement);
if (oldHeight + cellDisplacement > currentHeight)
{
currentHeight = oldHeight + cellDisplacement;
}
}
ArrayList images = cell.getImages(pagetop, indentBottom());
for (Iterator i = images.iterator(); i.hasNext();)
{
cellsShown = true;
Image image = (Image) i.next();
addImage(graphics, image, 0, 0, 0, 0, 0, 0);
}
// if a cell is allready added completely, remove it
if (cell.mayBeRemoved())
{
iterator.remove();
}
}
Hope this change can be included as standard for next version.
Regards,
Gerald.
