python音樂播放器1.1

經過在圖書館的努力，把之前的音樂播放器用wxpython子產品寫了下，圖如下：

這次加入了一些圖檔，實作了輕按兩下播放功能，完整代碼如下：

1.這裡說下win32com.client 裡的Dispatch(),為了這個我百度了半下午，終于找到了currentPlaylist的來曆，首先需要打開oleview.exe這個檔案

我的路徑是我重新下載下傳的裝的，你們的可能不是。打開後如圖，

輕按兩下後如圖

另外我在這裡（https://msdn.microsoft.com/en-us/library/windows/desktop/dd562659(v=vs.85).aspx）也找到了listbox輕按兩下切換音樂的方法

**2.**wxpython frame樣式

預設樣式 DEFAULT_FRAME_STYLE 是下面這些值的複合：
      # wx.MINIMIZE_BOX　|　wx.MAXIMIZE_BOX　|　wx.RESIZE_BORDER　|　
      # wx.SYSTEM_MENU　|　wx.CAPTION　|　wx.CLOSE_BOX　|　wx.CLIP_CHILDREN
      # 它包括最小化按鈕、最大化按鈕、系統菜單、标題欄、關閉按鈕、可變大小
