找到办法了，通过重构 QComboBox 类实现。
然后原本的 self.select_combo = QComboBox()改为重构后的 self.select_combo = CenteredComboBox()创建 现提供给大家参考 # -------------------------- class CenteredComboBox(QComboBox): def paintEvent(self, event): painter = QStylePainter(self) option = QStyleOptionComboBox() self.initStyleOption(option) # 绘制控件框架 painter.drawComplexControl(QStyle.CC_ComboBox, option) # 手动居中文本 text_rect = self.style().subControlRect( QStyle.CC_ComboBox, option, QStyle.SC_ComboBoxEditField) text_rect.adjust(25, 0, 0, 0) painter.drawText(text_rect, Qt.AlignCenter, self.currentText()) |
