Question

在选择适合我所需要方法的过程中，有些困惑。我有一个PyQt5应用程序，需要为其弹出QDialog（以显示进度）：

import sys
from PyQt5.QtGui import QIcon
from PyQt5.QtWidgets import QApplication, QMainWindow, QAction, QWidget, QDialog
from PyQt5.uic import loadUi


class TestWidget(QDialog):
    def __init__(self,*args):
        super(TestWidget,self).__init__(*args)
        loadUi('test2.ui',self)

class ClientReports(QMainWindow):
    def __init__(self,*args):
        super(ClientReports,self).__init__(*args)
        loadUi('clientreports.ui',self)
        self.subWindowCounter = 0
        testItem = QAction('&Test',self)
        testItem.setShortcut('Ctrl+T')
        testItem.setStatusTip('Test The New Process')
        testItem.triggered.connect(self.test_new_item)
        self.menubar.addAction(testItem)

    def test_new_item(self):
        tw = TestWidget(self)
        tw.exec()

app = QApplication(sys.argv)
mainWin = ClientReports()
mainWin.show()
sys.exit(app.exec_())

我的问题是：使用QDialog小部件可以使用户在整个屏幕上拖动窗口，而实际上，我需要停留在应用程序范围内。输入QMdiSubMenu选项-保留在应用程序框架的范围内，但我不能使其成为模态的。关于如何完成创建模态窗口但仍在应用程序框架范围内的任何建议？

Qt :: FramelessWindowHint
产生一个无边界的窗口。用户无法通过窗口系统移动或调整无边界窗口的大小。在X11上，标志的结果取决于窗口管理器及其理解Motif和/或NETWM提示的能力。现有的大多数现代窗口管理器都可以解决这个问题。

import sys
from PyQt5.QtGui     import QIcon
from PyQt5.QtWidgets import QApplication, QMainWindow, QAction, QWidget, QDialog
from PyQt5.uic       import loadUi
from PyQt5.QtCore    import Qt


class TestWidget(QDialog):
    def __init__(self,*args):
        super(TestWidget,self).__init__(*args)
        loadUi('test2.ui',self)
        # +++
        self.setWindowFlags(Qt.FramelessWindowHint)
        self.setAttribute(Qt.WA_TranslucentBackground)

class ClientReports(QMainWindow):
    def __init__(self,*args):
        super(ClientReports,self).__init__(*args)
        loadUi('clientreports.ui',self)
        self.subWindowCounter = 0
        testItem = QAction('&Test',self)
        testItem.setShortcut('Ctrl+T')
        testItem.setStatusTip('Test The New Process')
        testItem.triggered.connect(self.test_new_item)
        self.menubar.addAction(testItem)

    def test_new_item(self):
        tw = TestWidget(self)
        tw.exec()

app = QApplication(sys.argv)
mainWin = ClientReports()
mainWin.show()
sys.exit(app.exec_())
