简化pyqtproperty的创建。
autoqt的Python项目详细描述
autoqt
一个简单的单文件模块，使基本qt属性的设置有点 更好一点但不限制你。
如果qobjects具有许多只读属性和 很少有特殊的设置器或状态修改槽。
示例：
from PyQt5.QtCore import pyqtSignal, pyqtSlot
from autoqt import AutoObject, AutoProp
class SomeObject(AutoObject):
valuesChanged = pyqtSignal()
aNumber = AutoProp(int, 'valuesChanged', '_aNumber')
otherNumber = AutoProp(float, 'valuesChanged', '_otherNumber')
aString = AutoProp(str, 'valuesChanged', '_aString', write=True)
def __init__(self, parent=None):
super().__init__(parent=parent)
self._aNumber = 10
self._otherNumber = 20
self._aString = 'spam'
@pyqtSlot()
def incrementNumber(self):
self._aNumber += 1
self.valuesChanged.emit()
@otherNumber.setter
def otherNumber(self, value):
self._otherNumber = value + 2
self.valuesChanged.emit()
x = SomeObject()
print(x.aNumber) # 10
x.aNumber = 10 # throws AttributeError, readonly property
x.incrementNumber() # valuesChanged is emitted
print(x.aNumber) # 11
print(x.otherNumber) # 20
x.otherNumber = 40 # otherNumber.setter called, valuesChanged is emitted
print(x.otherNumber) # 42
print(x.aString) # 'spam'
x.aString = 'ham' # valuesChanged is emitted, writable property
print(x.aString) # 'ham'
