我试图将 QTableView 的内容打印到打印机 。 i 执行底部脚本, 并顺利运行, 没有任何错误 。 但所有数据在打印预览中都是不寻常的 。 这是 < href=" http:// img4up.com/ up2/ 7597767979177425743216. png" rel= “ nofollow” >pic 来自我的问题 - < a href=" http://www.qtcentre.org/threads/ 3796- QTableView-printing?
def printTable(self,printer,painter,area):
model = self.model
myTableView = self.view
printer = painter
rows = model.rowCount();
columns = model.columnCount();
totalWidth = 0.0;
totalPageHeight = 0.0;
totalHeight = 0.0;
for c in range(columns):
totalWidth += myTableView.columnWidth(c)
for p in range(45):
totalPageHeight += myTableView.rowHeight(p);
for r in range(rows):
totalHeight += myTableView.rowHeight(r);
xscale = area.width() / totalWidth;
yscale = area.height() / totalHeight;
pscale = area.height() / totalPageHeight;
painter.scale(xscale, pscale);
painter.translate(area.x() + xscale, area.y() + yscale);
x=0
#QStyleOptionViewItem option;
for r in range(rows):
++x
for c in range(columns):
idx = model.index(r,c);
option = myTableView.viewOptions();
option.rect = myTableView.visualRect(idx);
if r % 2 == 0:
brush= QtGui.QBrush(QtGui.QColor(220, 220, 220), QtCore.Qt.SolidPattern);
painter.fillRect(option.rect, brush);
myTableView.itemDelegate().paint(painter, option, idx);
if (x == 45):
ok = printer.newPage();
x=0;
painter.translate(0, -1350);
####################### Now print Table ######################
printer = QtGui.QPrinter()
painter = QtGui.QPainter()
painter.begin(printer )
self.printTable(printer,painter, printer.pageRect())
如果你有任何能帮助我的例子 请告诉我 非常感谢
