Question

我制作了一个文本框，想要从文本框中复制所有内容，然后通过按钮粘贴。

from PyQt4 import QtCore, QtGui

try:
    _fromUtf8 = QtCore.QString.fromUtf8
except AttributeError:
    def _fromUtf8(s):
        return s

try:
    _encoding = QtGui.QApplication.UnicodeUTF8
    def _translate(context, text, disambig):
        return QtGui.QApplication.translate(context, text, disambig, _encoding)
except AttributeError:
    def _translate(context, text, disambig):
        return QtGui.QApplication.translate(context, text, disambig)

class Ui_Form(object):
    def setupUi(self, Form):
        Form.setObjectName(_fromUtf8("Form"))
        Form.resize(943, 655)
        self.textEdit = Qsci.QsciScintilla(Form)
        self.textEdit.setGeometry(QtCore.QRect(10, 10, 861, 461))
        self.textEdit.setToolTip(_fromUtf8(""))
        self.textEdit.setWhatsThis(_fromUtf8(""))
        self.textEdit.setStyleSheet(_fromUtf8(""))
        self.textEdit.setFrameShape(QtGui.QFrame.StyledPanel)
        self.textEdit.setFrameShadow(QtGui.QFrame.Plain)
        self.textEdit.setObjectName(_fromUtf8("textEdit"))
        self.pushButton = QtGui.QPushButton(Form)
        self.pushButton.setGeometry(QtCore.QRect(530, 570, 93, 28))
        self.pushButton.setObjectName(_fromUtf8("pushButton"))

        self.retranslateUi(Form)
        QtCore.QObject.connect(self.pushButton, QtCore.SIGNAL(_fromUtf8("clicked()")), self.textEdit.selectAll)
        QtCore.QMetaObject.connectSlotsByName(Form)

    def retranslateUi(self, Form):
        Form.setWindowTitle(_translate("Form", "Form", None))
        self.pushButton.setText(_translate("Form", "run", None))

from PyQt4 import Qsci

if __name__ == "__main__":
    import sys
    app = QtGui.QApplication(sys.argv)
    Form = QtGui.QWidget()
    ui = Ui_Form()
    ui.setupUi(Form)
    Form.show()
    sys.exit(app.exec_())

我基本上想让按钮通过按钮到打印机来打印文本框的内容。

like so 

self.pushButton.setText(_translate("Form", "run", None))
self.pushButton.clicked.connect(self.Paste)

def Paste(self):
    print "content"

我尝试了很多，但没有一种像。

def Paste(self):
    x = QtCore.QObject.connect(self.pushButton, QtCore.SIGNAL(_fromUtf8("clicked()")), self.textEdit.selectAll)
    print x

为什么回拨中的重复连接信号会形成信号？

无论如何，QsciScintilla中的文本框，我阅读的文档正在使用QString QsciScintilla::text ( ) const。要输出到控制台，您只需调用此方法;

def Paste (self):
    print self.textEdit.text()

PyQT4如何通过Qpushbutton打印文本框内容到控制台
