我有一个连接到MySQL数据库并显示在QTableView中的查询结果的Python和PySide应用。 我需要打印的表格视图的内容。 下面是一些代码：
self.db_table = QtGui.QTableView(self)
self.model = QtSql.QSqlQueryModel()
self.model.setQuery("SELECT * FROM simpsons")
self.model.setHeaderData(1, QtCore.Qt.Horizontal, self.tr("First Name"))
self.model.setHeaderData(2, QtCore.Qt.Horizontal, self.tr("Last Name"))
self.db_table.setModel(self.model)
self.print_btn = QtGui.QPushButton("Print")
self.print_btn.clicked.connect(self.print_btn_clicked)
def print_btn_clicked(self):
printDialog = QtGui.QPrintDialog(self.printer, self)
if printDialog.exec_() == QtGui.QDialog.Accepted:
#printing code
我无法找到一个这样的例子，我不知道从文档太多，所以我会很感激一些帮助
谢谢
做到这一点的方法之一是表的内容转储到QTextDocument ，然后打印。
下面的演示使用一个简单的文本表，但HTML可以用来获得更多复杂的格式：
from PyQt4 import QtGui, QtCore
class Window(QtGui.QWidget):
def __init__(self, rows, columns):
QtGui.QWidget.__init__(self)
self.table = QtGui.QTableView(self)
model = QtGui.QStandardItemModel(rows, columns, self.table)
for row in range(rows):
for column in range(columns):
item = QtGui.QStandardItem('(%d, %d)' % (row, column))
item.setTextAlignment(QtCore.Qt.AlignCenter)
model.setItem(row, column, item)
self.table.setModel(model)
self.buttonPrint = QtGui.QPushButton('Print', self)
self.buttonPrint.clicked.connect(self.handlePrint)
self.buttonPreview = QtGui.QPushButton('Preview', self)
self.buttonPreview.clicked.connect(self.handlePreview)
layout = QtGui.QGridLayout(self)
layout.addWidget(self.table, 0, 0, 1, 2)
layout.addWidget(self.buttonPrint, 1, 0)
layout.addWidget(self.buttonPreview, 1, 1)
def handlePrint(self):
dialog = QtGui.QPrintDialog()
if dialog.exec_() == QtGui.QDialog.Accepted:
self.handlePaintRequest(dialog.printer())
def handlePreview(self):
dialog = QtGui.QPrintPreviewDialog()
dialog.paintRequested.connect(self.handlePaintRequest)
dialog.exec_()
def handlePaintRequest(self, printer):
document = QtGui.QTextDocument()
cursor = QtGui.QTextCursor(document)
model = self.table.model()
table = cursor.insertTable(
model.rowCount(), model.columnCount())
for row in range(table.rows()):
for column in range(table.columns()):
cursor.insertText(model.item(row, column).text())
cursor.movePosition(QtGui.QTextCursor.NextCell)
document.print_(printer)
if __name__ == '__main__':
import sys
app = QtGui.QApplication(sys.argv)
window = Window(25, 2)
window.resize(300, 400)
window.show()
sys.exit(app.exec_())
当一种方法来打印多页QTable搜索，你可能会发现一个人要么说要转储到另外，QTextDocument在@ ekhumoro的答案，或手动直接从表上你自己的，印刷管理页面大小。
下面是如何，你可以直接从打印表格，进行自定义打印方法粗略例如：
class Window(QtGui.QDialog):
def __init__(self):
...
self.db_table = TableView(self)
def print_table(self):
dialog = QtGui.QPrintDialog(self)
if dialog.exec_() == dialog.Accepted:
self.db_table.print_(dialog.printer())
class TableView(QtGui.QTableView):
def print_(self, printer):
model = self.model()
rows = model.rowCount()
cols = model.columnCount()
totalWidth = 0.0
for i in xrange(cols):
totalWidth += self.columnWidth(i)
painter = QtGui.QPainter(printer)
pageSize = printer.pageRect()
pageHeight = pageSize.height()
scaleX = pageSize.width() / totalWidth
painter.scale(scaleX, 1.0)
totalHeight = 0.0
newPage = False
offsetY = 0
for row in xrange(rows):
height = self.rowHeight(row)
totalHeight += height
if totalHeight > pageHeight:
totalHeight = height
printer.newPage()
newPage = True
for col in xrange(cols):
idx = model.index(row, col)
option = self.viewOptions()
option.rect = self.visualRect(idx)
if newPage:
offsetY = option.rect.y()
newPage = False
option.rect.moveTop(option.rect.y()-offsetY)
self.itemDelegate().paint(painter, option, idx)
painter.end()
