Python音乐播放器

更新日志:
20221031:添加独立播放列表

展示图片:
<Python>PyQt5自己编写一个音乐播放器(优化版)_第1张图片

主要功能:
1、进度条拖动
2、音量拖动
3、独立播放列表
4、窗体渐变色(UI美化方面)

概述:
之前刚学python的时候,就照着网上的代码实现一个简单的播放器功能:
使用python加PyQt5,利用QMediaPlayer写一个简易的音乐播放器(进度条拖动,音量改变,播放停止切换,歌曲列表))
不过,这个博文里的程序功能比较简单,然后界面也没有设置:

<Python>PyQt5自己编写一个音乐播放器(优化版)_第3张图片
对比一下,外观上差别还是挺明显的。UI的配色可以根据自己的喜好来设置(QSS文件里设置)

本文主要说一下两个方面的实现:
1、独立播放列表
2、界面样式设置

其他功能设置就不多介绍,可以去看我之前写的那篇博文,我在底下也会把完整代码重新贴一遍。

独立播放列表的实现,主要在于多窗口之间的函数调用和参数传递实现,这个我也单独写过一个介绍:
<Python>PyQt5,多窗口之间参数传递和函数调用

有兴趣的可以看看。

播放列表窗口代码:

class music_list_win(QWidget):
    """歌曲列表窗口"""
    def __init__(self,m_l):
        super().__init__()
        self.music_list1=m_l
        #print(self.music_list1)
        self.initUI()
    def initUI(self):
               
        self.qss_style_file='music_play_pro2022\qss_music_list_win.qss'
        self.qss1=QssRead.readQSS(self.qss_style_file)      
               
        self.song_lists=[]
        
        self.list_music_list=QListWidget(self)
        self.list_music_list.doubleClicked.connect(self.music_list_doubleplay_func)
        #self.qlist.setStyle(QStyleFactory.create('Fusion'))
        self.list_music_list.setGeometry(10, 10, 230, 500)
        
        self.music_list_add()
        
        self.setGeometry(920, 100, 250, 600)
        self.setWindowTitle('播放列表')
        self.setStyleSheet(self.qss1)
        #self.setWindowFlag(Qt.FramelessWindowHint)
        self.setWindowIcon(QIcon("music_play_pro2022\musicicon2.jpeg"))
        #self.show()

列表填充函数:

    def music_list_add(self):
        
        for i,l in enumerate( self.music_list1):
            #print(l[0])
            self.list_music_list.addItem("[ "+str(i)+" ]"+"--"+l[0])

调用主窗体函数的函数:
这里mp1是主窗体的实例化,doubleplay_subwin()是主窗体的一个函数。

    def music_list_doubleplay_func(self):
        """"""
        #music_list_index=self.list_music_list.currentRow()

        mp1.doubleplay_subwin()
        

主窗体传递参数给播放列表窗体:
主窗体获取歌曲列表,并且同时将列表传递给子窗体(播放列表窗体),并且显示窗体。

  def load_music_file_func(self):
        #获取歌曲所在文件夹路径
        self.qlist.clear()
        self.cur_path=QFileDialog.getExistingDirectory(self, "选取文件夹", 'E:/')
        #判断歌曲文件路径是否存在
        if os.path.exists(self.cur_path):
            #将文件夹中的所有歌曲添加到List中
            for song in os.listdir(self.cur_path):
                #print(song)
                self.songs_list.append([song, os.path.join(self.cur_path, song).replace('\\', '/')])
                music_list.append([song, os.path.join(self.cur_path, song).replace('\\', '/')])
                self.qlist.addItem(song)
            self.music_list_win1=music_list_win(music_list)
            self.music_list_win1.show()

可以看到优化过的界面,背景色为渐变,看起来也好看一些,这里在qss文件里设置:

QWidget
{
    background-color: qlineargradient(x1:0, y1:0, x2:1, y2:1, stop:0 #81F5D8,stop:0.2 #43ABE7,stop:0.5 #57E7EC stop:1 #8EF068);
}

qlineargradient是设置渐变色的,可以调整渐变方向、渐变点、渐变颜色等,以调出自己喜欢的配色。
