我尝试创建QML-PYSIDE计算器。但是我找不到那样的例子。我还检查了pyside wiki，但无法理解如何一起运行QML-PySide。 例如，我想用QML-PySİde运行附加应用程序。（a + b = c）。我可以控制由QtDesigner用Python创建的附加应用程序GUI（sumui.ui）（由PySideTools转换）。但我无法用Python控制添加应用程序QML（inputtext，button）。 我是python-qt的新手。因此，我输入了pyside-qtdesigner和qml GUI来理解PySide-QtWidgets和PySide-QML UI之间的依赖关系。 （抱歉我的英语不好）
PySide添加应用程序：
app的图片：http://postimg.org/image/envp8jgg9/
addition.py：
# addition.py
from PySide import QtCore, QtGui
from sumui import Ui_Form
import sys
def derece(degrees):
return degrees*((2*pi)/400)
class hesap(QtGui.QWidget):
def __init__(self):
QtGui.QWidget.__init__(self)
self.ui = Ui_Form()
self.ui.setupUi(self)
# Validations
tempValidator = QtGui.QDoubleValidator()
tempValidator.setNotation(QtGui.QDoubleValidator.StandardNotation)
self.ui.a.setValidator(tempValidator)
self.ui.b.setValidator(tempValidator)
self.setupConnections()
def topla(self):
a1 = float(self.ui.a.text())
b1 = float(self.ui.b.text())
c1 = a1 + b1
cc1 = str(c1)
self.ui.c.setText(str(cc1))
def setupConnections(self):
self.connect(self.ui.sum, QtCore.SIGNAL('clicked()'),
self.topla)
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
window = hesap()
window.show()
sys.exit(app.exec_())
QML GUI：http://postimg.org/image/pocxfcf19/ addition.qml：
import QtQuick 1.1
Rectangle {

anchors.centerIn: parent

height: 200

如何使用PySide运行QML添加UI？或者有像PySide-QML计算器这样的例子吗？ 感谢

以下是单击按钮时更新分数的界面示例。它可能在没有与python的很多交互的情况下进行设计，但在许多情况下，无论接口层有多么天才，我们都希望信号能够归结为Python。
import sys
from PySide import QtCore,QtDeclarative, QtGui
class QtScoreInterface(QtCore.QObject ):
signaller_score_a = QtCore.Signal(str)
signaller_score_b = QtCore.Signal(str)
def __init__(self):
QtCore.QObject.__init__(self)
self.score_a = 0
self.score_b = 0
@QtCore.Slot()
def aScored(self):
print ("A_scored");
self.score_a += 1
self.updateScore()
@QtCore.Slot()
def bScored(self):
print ("B_scored");
self.score_b += 1
self.updateScore()
@QtCore.Slot()
def startMatch(self):
print ("Game start stopped");
def updateScore(self):
self.signaller_score_a.emit(str(self.score_a))
self.signaller_score_b.emit(str(self.score_b))
class MainView( QtDeclarative.QDeclarativeView ):
def __init__( self, parent=None):
super( MainView, self ).__init__( parent )
self.setWindowTitle( "ScoreKeeper" )
self.setSource( QtCore.QUrl.fromLocalFile( './main.qml' ) )
self.setResizeMode( QtDeclarative.QDeclarativeView.SizeRootObjectToView )
qApplication = QtGui.QApplication( sys.argv )
window = MainView()
window.show();
qcontext = window.rootContext()
interface = QtScoreInterface()
qcontext.setContextProperty("qScoreInterface",interface)
interface.signaller_score_a.connect(window.rootObject().updateScoreA)
interface.signaller_score_b.connect(window.rootObject().updateScoreB)
sys.exit( qApplication.exec_() )
这是QML文件（main.qml）：

score_b.text = string

那么你想在QML GUI上显示pyside方法的结果吗？ 现在你有两个UI：Qt Widget和QML。我想你想从pyside app（只有QML UI）控制QML gui。 首先你必须从pyside（http://qt-project.org/wiki/Hello-World-in-PySide-and-QtQuick）加载qml文件。第二件事是SIGNALS和SLOTS（http://www.qtcentre.org/threads/36782-SOLVED-qml-signal-with-c-slot）。 你的计算按钮应该发出带有a和b变量到pyside层的信号，pyside层应该有该信号的插槽，并且该槽将计算两个变量并发出信号，结果为qml槽，qml槽将在qml ui中显示该结果。
