Question

所以我已经想出了如何在QDialog中动态生成控件的问题我问here但现在我无法在字典中设置QSpinBox的值以下

books = {
        'Contact':['Carl Sagan', 2],
        'End of Faith':['Sam Harris', 7],
        'on Mars':['Patrick Moore', 1],

        }


def buildUi(self):
    self.gridLayout = QtGui.QGridLayout()
    self.gridLayout.setSpacing(10)
    for index, (key, values) in enumerate(self._data.iteritems()):
        getLbl = QtGui.QLabel("Get", self)
        label = QtGui.QLabel(key, self)
        chkBox = QtGui.QCheckBox(self._data[key][0], self)
        chkBox.setToolTip("Click here to get the book")
        version = QtGui.QSpinBox(self._data[key][-1], self)
        self.gridLayout.addWidget(getLbl, index, 0)
        self.gridLayout.addWidget(label, index, 1)
        self.gridLayout.addWidget(chkBox, index, 2)
        self.gridLayout.addWidget(version, index, 3)
    self.layout = QtGui.QVBoxLayout()
    self.okBtn = QtGui.QPushButton("OK")
    self.layout.addLayout(self.gridLayout)
    self.horLayout = QtGui.QHBoxLayout()
    self.horLayout.addStretch(1)
    self.horLayout.addWidget(self.okBtn)
    self.layout.addLayout(self.horLayout)
    self.setLayout(self.layout)

以下是我收到的错误消息：

Traceback (most recent call last):
  File "~/Development/custom/MessageBox.py", line 58, in _launchMessageBox
    dlg = MessageBox(self._data)
  File "~/Development/custom/MessageBox.py", line 10, in __init__
    self.buildUi()
  File "~/Development/custom/MessageBox.py", line 21, in buildUi
    version = QtGui.QSpinBox(self._data[key][-1], self)
TypeError: QSpinBox(QWidget parent=None): argument 1 has unexpected type 'int'
[Finished in 4.5s]

另外如何在QSPinBox中设置限制？

Answer 1

根据QSpinBox.__init__ documentation，它只需要parent参数。

替换以下行：

version = QtGui.QSpinBox(self._data[key][-1], self)

使用：

version = QtGui.QSpinBox(self)

如果要设置初始值，请使用setValue：

version.setValue(self._data[key][-1])

QSpinBox没有从数据中获取int值
