如何在外部單擊時關閉QDialog並在單擊子窗口小部件時關閉？

Question

我有一點問題。 當我按下QPushButton（child）或在QDialog外部單擊時，我嘗試關閉QDialog。 我不想在按鈕的功能中使用connect關閉。 我想在QDialog檢測到孩子被點擊時關閉。

對不起我的英語。

非常感謝。

if __name__ == '__main__':
    app = QApplication(sys.argv)
    window = Main()
    window.activateWindow()
    window.show()

    sys.exit(app.exec_())

此代碼，在SimpleDialog中沒有檢測到focusOut :(有解決方案嗎？

我想向您展示我針對問題找到的解決方案。
首先，如何關閉窗口小部件SimpleDialogal單擊？
我在小部件的末尾做了一個小的修改，這使我可以擴展它並管理其整個區域。

main = QVBoxLayout()
main.addWidget(...contenido...)

self.fullWidget = QWidget()
self.fullWidget.setLayout(main)
self.fullWidget.setStyleSheet("background-color: RGB(0,0,0,30)")

l = QHBoxLayout()
l.addWidget(self.fullWidget)

self.showFullScreen()
self.setLayout(l)

因此，通過這種方式，我可以編寫mouseReleaseEvent來檢測頂部區域和單擊關閉的時間。

def mouseReleaseEvent(self, QEvent):
    if QApplication.widgetAt(QEvent.pos()) == self.fullWidget:
        self.close()

現在，作為解決關閉的問題SimpleDialog按下時SimpleDialogItem約為寫mouseReleaseEvent與QApplication的方法尋父，並將其關閉

def mouseReleaseEvent(self, *args, **kwargs):
    for widget in QApplication.topLevelWidgets():
        if type(widget) == SimpleDialog:
            widget.close()
