但我想在标签栏旁边添加一个新的标签按钮,类似于任何浏览器……
我搜索了它,但我无法找到任何添加加号按钮的方法…… TabWidget中是否有任何属性或者我是否需要在那里添加新按钮..？
上述代码的来源是：Dynamically change view of tabs in a QTabWidget (PyQt)
self.tabButton = QtGui.QToolButton(self)
self.tabButton.setText('+')
font = self.tabButton.font()
font.setBold(True)
self.tabButton.setFont(font)
self.tabwidget.setCornerWidget(self.tabButton)
self.tabButton.clicked.connect(self.add_page)总结
以上是编程之家为你收集整理的python-2.7 – 向TabWidget pyqt4添加加号按钮全部内容，希望文章能够帮你解决python-2.7 – 向TabWidget pyqt4添加加号按钮所遇到的程序开发问题。
