python qt tabwidget 样式

以下是一个简单的Python Qt TabWidget样式的例子：

from PyQt5 import QtWidgets, QtGui, QtCore

class TabWidget(QtWidgets.QTabWidget):
    def __init__(self, parent=None):
        super(TabWidget, self).__init__(parent)
        self.setStyleSheet("""
            QTabWidget::pane {
                border-top: 2px solid #C2C7CB;
            }
            QTabBar::tab {
                background-color: #C2C7CB;
                border: 2px solid #C2C7CB;
                border-top-left-radius: 4px;
                border-top-right-radius: 4px;
                min-width: 8ex;
                padding: 2px;
            }
            QTabBar::tab:selected, QTabBar::tab:hover {
                background-color: #F2F3F4;
            }
            QTabBar::tab:selected {
                border-color: #C2C7CB;
            }
            QTabBar::tab:!selected {
                margin-top: 2px;
            }
            QTabBar::tab:first:selected {
                border-top-left-radius: 4px;
            }
            QTabBar::tab:last:selected {
                border-top-right-radius: 4px;
            }
            QTabBar::tab:only-one {
                border-top-left-radius: 4px;
                border-top-right-radius: 4px;
            }
        """)

        self.addTab(QtWidgets.QWidget(), "Tab 1")
        self.addTab(QtWidgets.QWidget(), "Tab 2")
        self.addTab(QtWidgets.QWidget(), "Tab 3")

if __name__ == '__main__':
    import sys
    app = QtWidgets.QApplication(sys.argv)
    tab_widget = TabWidget()
    tab_widget.show()
    sys.exit(app.exec_())
