[英]PyQt5 widgets intended to be transparent to show QVideoPlayer pass through video and adopt QMainWindow background
我有一個 QMainWindow ,其中 QVideoWidget 設置為中央小部件。 該視頻就像我正在制作的二十一點游戲的主要 window 的背景。 我有兩個按鈕,我想以部分透明的方式放置在視頻頂部。
這就是我希望 window 的樣子:
但我已經嘗試了幾十種方法來實現透明按鈕背景並且不能。 任何透明度嘗試都會直接“剪切”視頻並顯示 MainWindow 的背景。 例如,我將主 window 背景設置為藍色。
這是運行時顯示的內容:
如何使視頻出現在透明按鈕后面?
我嘗試過但沒有成功的事情:堆疊布局設置為 StackAll,在按鈕樣式表中插入透明背景圖像,使用透明顏色代碼 (rgba(0,0,0,0)),將 videowidget 設置為按鈕的父小部件.
我的代碼的相關部分:
from PyQt5 import QtWidgets, QtMultimediaWidgets, QtMultimedia, QtCore, QtGui, Qt
from PyQt5.QtWidgets import QApplication, QMainWindow, QLabel, QPushButton, QLineEdit, QComboBox
from PyQt5.QtGui import QTransform
import sys
import random
class MyWindow(QMainWindow):
def __init__(self):
super(MyWindow, self).__init__()
self.setGeometry(0, 0, 1920, 1080)
self.setWindowTitle("Cutie Pie Casino")
self.setStyleSheet('background-color: blue;')
self.Welcome()
def Welcome(self):
welcome_font = QtGui.QFont()
welcome_font.setPointSize(30)
welcome_font.setFamily('Broadway')
welcome_font_small = QtGui.QFont()
welcome_font_small.setPointSize(20)
welcome_font_small.setFamily('Broadway')
# create link to movie file
movie_file = QtCore.QUrl.fromLocalFile('C:/Users/Owner/PycharmProjects/Black Jack/video/'
'Cutie Pie Casino Video.mp4')
vid_media = QtMultimedia.QMediaContent(movie_file)
# create video widget
self.videoWidget = QtMultimediaWidgets.QVideoWidget()
self.videoWidget.setGeometry(0,0,1920,1080)
self.videoWidget.setStyleSheet('background-color: blue')
# create media player object (video widget goes in media player)
self.mediaPlayer = QtMultimedia.QMediaPlayer(None,
QtMultimedia.QMediaPlayer.VideoSurface)
self.mediaPlayer.setVideoOutput(self.videoWidget)
# playlist
self.playlist = QtMultimedia.QMediaPlaylist()
self.playlist.setCurrentIndex(0)
self.playlist.setPlaybackMode(QtMultimedia.QMediaPlaylist.Loop)
self.playlist.addMedia(vid_media)
# add content to media player
self.mediaPlayer.setPlaylist(self.playlist)
self.mediaPlayer.play()
self.setCentralWidget(self.videoWidget)
self.PlayCardsButton = QPushButton(self)
self.PlayCardsButton.setText('Play Blackjack')
self.PlayCardsButton.setFont(welcome_font_small)
self.PlayCardsButton.setGeometry(765,500,400,150)
self.PlayCardsButton.clicked.connect(self.InitializeTable)
self.PlayCardsButton.setStyleSheet('background-color: rgba(0,0,0,0); color: black')
self.GameSetupButton = QPushButton(self)
self.GameSetupButton.setGeometry(765, 700, 400, 150)
self.GameSetupButton.setFont(welcome_font_small)
self.GameSetupButton.setText('Game Setup')
self.GameSetupButton.setStyleSheet('background-color: rgba(0,0,0,0); color: black')
您可以嘗試: self.PlayCardsButton.setFlat(True)
