Hi lkryss,
You should be able to put a text using drawString and move the JTable
down using translate. Here is an example of a modified print method of
Report.java from
http://java.sun.com/developer/onlineTraining/Programming/JDCBook/advprint.html#pe
to put a text before JTable.
public int print(Graphics g, PageFormat pageFormat,
int pageIndex) throws PrinterException {
Graphics2D g2 = (Graphics2D) g;
g2.setColor(Color.black);
int fontHeight=g2.getFontMetrics().getHeight();
int fontDesent=g2.getFontMetrics().getDescent();
//leave room for page number
double pageHeight = pageFormat.getImageableHeight()-fontHeight;
double pageWidth = pageFormat.getImageableWidth();
double tableWidth = (double)
tableView.getColumnModel().getTotalColumnWidth();
// height of TEXT BEFORE JTable
double textHeight = 10f;
double scale = 1;
if (tableWidth >= pageWidth) {
scale = pageWidth / tableWidth;
}
double headerHeightOnPage=
tableView.getTableHeader().getHeight()*scale;
double tableWidthOnPage=tableWidth*scale;
double oneRowHeight=(tableView.getRowHeight()+
tableView.getRowMargin())*scale;
int numRowsOnAPage=
(int)((pageHeight-headerHeightOnPage)/oneRowHeight);
double pageHeightForTable=oneRowHeight*numRowsOnAPage;
int totalNumPages= (int)Math.ceil((
(double)tableView.getRowCount())/numRowsOnAPage);
if(pageIndex>=totalNumPages) {
return NO_SUCH_PAGE;
}
g2.translate(pageFormat.getImageableX(),
pageFormat.getImageableY());
g2.drawString("Page: "+(pageIndex+1),(int)pageWidth/2-35,
(int)(pageHeight+fontHeight-fontDesent));//bottom
center
//PUT TEXT ON TOP OF THE PAGE BEFORE JTABLE
g2.drawString("TEXT before JTable",
(int)0, (int)textHeight);
// MOVE TABLE USING TRANSLATE with added textHeight
g2.translate(0f,headerHeightOnPage+textHeight);
g2.translate(0f,-pageIndex*pageHeightForTable);
//If this piece of the table is smaller than the size available,
//clip to the appropriate bounds.
if (pageIndex + 1 == totalNumPages) {
int lastRowPrinted = numRowsOnAPage * pageIndex;
int numRowsLeft = tableView.getRowCount() -
lastRowPrinted;
g2.setClip(0, (int)(pageHeightForTable * pageIndex),
(int) Math.ceil(tableWidthOnPage),
(int) Math.ceil(oneRowHeight * numRowsLeft));
}
//else clip to the entire area available.
else{
g2.setClip(0, (int)(pageHeightForTable*pageIndex),
(int) Math.ceil(tableWidthOnPage),
(int) Math.ceil(pageHeightForTable));
}
g2.scale(scale,scale);
tableView.paint(g2);
g2.scale(1/scale,1/scale);
g2.translate(0f,pageIndex*pageHeightForTable);
g2.translate(0f, -headerHeightOnPage);
g2.setClip(0, 0,(int) Math.ceil(tableWidthOnPage),
(int)Math.ceil(headerHeightOnPage));
g2.scale(scale,scale);
tableView.getTableHeader().paint(g2);//paint header at top
return Printable.PAGE_EXISTS;

hello
i try to print a jtable and some text before and after my jtable. printing the
jtable is ok, and some text after too. but i don't really understand the code
(took from
http://java.sun.com/developer/onlineTraining/Programming/JDCBook/advprint.html
) i'd like to shift the jtable below some text.
someone has an idea please
(excuse my english )
code:

table vers le bas ???? touite la page vers le bas

semble faire pareil que la ligne du dessus
