問題描述

嗨，目前我的程序看起來像這樣

我希望它看起來像這樣

    app = QtWidgets.QApplication(sys.argv)
    MainWindow = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())

我幾乎到處都用谷歌搜索過，但我似乎找到的答案大多是針對 PyQt4 的。

我設法找到了一個關於隱藏標題欄的答案，代碼如下所示

self.setWindowFlag(Qt.FramelessWindowHint)

但這並沒有得到我想要的結果。 我得到的只是標題欄消失了，但我的程序仍然有一個灰色的矩形背景。

該白色邊框是布局的內部邊距，因此只需使用 setContentsMargins，對於圓形邊框，您也必須使用遮罩，顯然還有 Qt::FramelessWindowHint 標志：

from PyQt5.QtCore import QRect, Qt
from PyQt5.QtGui import QRegion
from PyQt5.QtWidgets import QApplication, QMainWindow

from design import Ui_MainWindow


class MainWindow(QMainWindow, Ui_MainWindow):
    def __init__(self, parent=None):
        super().__init__(parent)
        self.setupUi(self)

        self.verticalLayout.setContentsMargins(0, 0, 0, 0)
        self.setWindowFlag(Qt.FramelessWindowHint)

        radius = 10
        base = self.rect()
        ellipse = QRect(0, 0, 2 * radius , 2 * radius)

        base_region = QRegion(base.adjusted(radius, 0, -radius, 0))
        base_region |= QRegion(base.adjusted(0, radius, 0, -radius))
        
        base_region |= QRegion(ellipse, QRegion.Ellipse)
        ellipse.moveTopRight(base.topRight())
        base_region |= QRegion(ellipse, QRegion.Ellipse)
        ellipse.moveBottomRight(base.bottomRight())
        base_region |= QRegion(ellipse, QRegion.Ellipse)
        ellipse.moveBottomLeft(base.bottomLeft())
        base_region |= QRegion(ellipse, QRegion.Ellipse)

        self.setMask(base_region)


if __name__ == "__main__":
    import sys
    app = QApplication(sys.argv)
    w = MainWindow()
    w.show()
    sys.exit(app.exec_())
