Answer 1

如果您想点击QLabel的网址，那么您需要为其设置一些属性（setOpenExternalLinks除外），例如setTextInteractionFlags到Qt::TextBrowserInteraction和{{ 1}}到setTextFormat

编辑（将这些内容添加到您需要点击Qt::RichText上的网址的每个标签上）：

etiket

Answer 2

QLabel一般不可点击，但您可以重载QLabel.mousePressEvent或QLabel.mouseReleaseEvent方法来识别点击信号;像这样：

class Form(QWidget):
    def __init__(self):
        QDialog.__init__(self)
        self.t=QLabel('Click Me',self)
        self.t.mousePressEvent=self.labelClick

    def labelClick(self,e):
        if e.button() == Qt.LeftButton:
            print('Clicked')
        QLabel.mousePressEvent(self.t,e)

QLabel在我的程序中无法点击
