删除PyQt5 QWidget上的边框

我目前正在尝试在辅助屏幕上显示无边界图像,使用PyQT5修改Matplotlib的默认图形。在上下文中,这是在空间光调制器上显示图像,该调制器使用简单的HDMI输出,并由我的计算机作为辅助屏幕处理。其分辨率为1280x1024。我按照How to disable the maximize, minimize and close button of the matplotlib window?的答案进行了链接,但仍然在图形的底部添加了边框,并且在全屏显示图形时也添加了边框。这是我用来生成窗口的类:

class SLMscreen:


def __init__(self, resX, resY):
    """
    Initializes the window to be displayed on the SLM
    :param resX: Width in pixel
    :param resY: Height in pixel
    """
    #dirty way of finding the primary screen size, could be improved
    app = QApplication([])
    screen_resolution = app.desktop().screenGeometry()
    width, height = screen_resolution.width(), screen_resolution.height()
    mpl.rcParams['toolbar'] = 'None'
    self.fig = plt.figure(figsize=(resX / 100, resY / 100), frameon=False)
    self.ax = plt.axes([0,0,1,1], frameon=False)
    self.ax.get_xaxis().set_visible(False)
    self.ax.get_yaxis().set_visible(False)
    self.fig.patch.set_visible(False)
    self.ax.patch.set_visible(False)
    window = self.fig.canvas.parent()
    window.setWindowFlags(Qt.FramelessWindowHint | Qt.CustomizeWindowHint)
    window.setGeometry(width,0,resX,resY)
    window.layout().setContentsMargins(0, 0, 0, 0)
    window.layout().setSpacing(0)

    #self.fig.canvas.parent().showFullScreen()
    #self.figManager.window.showMaximized()

def update(self, array):
    """
    Displays the array on the SLM
    :param array: np.ndarray
    """
    self.ax.imshow(array, cmap='gray', aspect='equal')
    self.figManager.window.showMaximized()

我用这个非常简单的片段测试了窗口的良好初始化:

import numpy as np
from SLM import SLMscreen

mask =255* np.zeros((1024,1280), dtype='uint8')
slm_screen = SLMscreen(1280,1024)
slm_screen.update(mask)

最后,窗口如下所示:

The window still has borders left, right and bottom

任何帮助都将不胜感激
