wxPython按钮可加载多个图像

对，一个背景故事。为了我的大学项目，我正在为鼓创作一位节奏老师。所以程序将要做的是加载一个鼓符号，以及一个与鼓符号匹配的音频文件。用户按下“播放”按钮，它播放一个与符号匹配的短鼓点。到目前为止，我已经有一个按钮来播放加载的Wav。文件，以及另一个用于加载图像的按钮。我希望我说的有道理

所以我的问题是，有没有人有这样一个函数？在中，一种按钮，用于同时加载图像和音频文件。如果再次按下按钮，它将加载另一个图像和音频文件，覆盖以前加载的内容。我将有相当数量的图像和音频文件加载。重要的一点是，图像必须与音频文件匹配

同样，我有一个播放音频文件的按钮，另一个只是加载图像的按钮（我这样做是因为我是新手，刚刚学习如何实现这些功能）

不管怎样，我会发布一段代码，它应该更有意义！抱歉，如果这是一段很长的阅读！我只是想把我正在做的事情放在后面

以下是一种方法：

• 首先，定义定义目录的全局变量 包含图像和wav文件：

  IMAGE_DIR = '/path/to/images'
  SOUND_DIR = '/path/to/sounds'
  

  如果你愿意，你可以使用同一个目录。我假设
  • 所有图像都是以

    .jpg

    结尾的JPEG文件
  • 如果图像名为

    foo.jpg

    ，则关联的wav文件为 调用

    foo.wav

• 接下来，在

  窗口2.\uuuu init\uuuu

  方法中定义两个新属性：

  self.images = IT.cycle([filename for filename in os.listdir(IMAGE_DIR) if filename.endswith('.jpg')])
  self.image_file = None
  

  在文件顶部，导入

  itertools

  模块：

  import itertools as IT
  

  os.listdir（IMAGE\u DIR）

  返回文件名列表 返回循环遍历列表中的项的iterable 无穷大
  返回iterable中的项

  self.images

  下一步

  。我们将在下面使用它

• 现在，

  loadImage

  可以这样写：

  def loadImage(self, event):
      self.image_file = next(self.images)
      image_file = os.path.join(IMAGE_DIR, self.image_file)
      bmp = wx.Image(image_file, wx.BITMAP_TYPE_ANY).ConvertToBitmap()
      wx.StaticBitmap(self.panel, -1, bmp, pos=(200, 50), size=(417, 133))
  

并播放相关的wav文件：

   def onPlaySound(self, event):  
        sound_file, ext = os.path.splitext(self.image_file)
        sound_file = os.path.join(SOUND_DIR, sound_file + '.wav')
        sound = wx.Sound(sound_file)
        sound.Play(wx.SOUND_ASYNC)

由于正在使用和，请确保也导入文件顶部的

os

模块

您如何知道下一张图片的文件名是什么，以及它与哪个

.wav

文件关联？好吧，我将根据它们的名称来命名。示例图像和.wav文件将被称为“notation1”等等。但这可能是主要的问题，将它们加载在一起。我只是想问一下是否有人有这样做的想法。我很困惑，我是Python.notation1.wav，notation1.jpgI的新手，一直在搜索如何做。但通常谷歌搜索只会返回“位图按钮”等等。我对你描述的行为有点困惑。原因如下：当你按下

Next

按钮时，

loadImage

方法会运行。这个方法只会更改图像，不会播放任何声音。那么，“按下Next按钮只会加载下一个.wav文件”怎么可能。这里有一个建议：在

loadImage

方法中放入

print（self.image\u文件）

，然后放入

print（sound\u文件）

在

onPlaySound

方法中。这可能会给我们一个线索，说明当按下

Next

和

Play

按钮时会发生什么。如果这还不能充分说明情况，请发布完整的代码。我无法重现您描述的行为。我正在发布我正在使用的代码。请我想我可能终于看到问题了。我们不应该在面板中插入越来越多的图像，而应该只插入一次，然后调用

SetBitmap

来更改图像。我已经更新了我的帖子这似乎不起作用，因为我刚刚得到一个错误-img=img.Scale（240240）UnboundLocalError:赋值前引用的局部变量“img”
