wxPython : Creating a soundboard with panels

Question

I am making a quick and dirty soundboard using the wxPython package and was wondering how to go by implementing a scroll-list of sounds to play.

Here is a picture of what I am trying to convey: https://i.sstatic.net/gZsGS.png

and here is my code so far:

import wx

class windowClass(wx.Frame):
    def __init__(self, *args, **kwargs):
        super(windowClass,self).__init__(*args,**kwargs)
        self.basicGUI()
    def basicGUI(self):
        panel = wx.Panel(self)
        menuBar = wx.MenuBar()
        fileButton = wx.Menu()
        editButton = wx.Menu()
        exitItem = fileButton.Append(wx.ID_EXIT, 'Exit','status msg...')

        menuBar.Append(fileButton, 'File')
        menuBar.Append(editButton, 'Edit')

        self.SetMenuBar(menuBar)
        self.Bind(wx.EVT_MENU, self.Quit, exitItem)

        wx.TextCtrl(panel,pos=(10,10), size=(250,150))

        self.SetTitle("Soundboard")
        self.Show(True)
    def Quit(self, e):
        self.Close()
def main():
    app = wx.App()
    windowClass(None)
    app.MainLoop()


main()

My question remains, how does one load a list of sounds on that panel and click a certain button to play that sound. I don't really care about implementing pause and fast forward features since this is only going to play really quick sound files.

Thanks in advance.

Answer 1

Just removed the text widget, replaced by a listbox, and hooked a callback on item click, slightly elaborate: when clicking, it finds the position of the item, retrieves the label name and fetches the filename in the dictionary (we want to play a .wav file with a path, but not necessarily display the full filename)

I refactored the code so callbacks and other attributes are private, helps the lisibility.

import wx

class windowClass(wx.Frame):
    def __init__(self, *args, **kwargs):
        super(windowClass,self).__init__(*args,**kwargs)
        self.__basicGUI()
    def __basicGUI(self):
        panel = wx.Panel(self)
        menuBar = wx.MenuBar()
        fileButton = wx.Menu()
        editButton = wx.Menu()
        exitItem = fileButton.Append(wx.ID_EXIT, 'Exit','status msg...')

        menuBar.Append(fileButton, 'File')
        menuBar.Append(editButton, 'Edit')

        self.SetMenuBar(menuBar)
        self.Bind(wx.EVT_MENU, self.__quit, exitItem)

        self.__sound_dict = { "a" : "a.wav","b" : "b.wav","c" : "c2.wav"}
        self.__sound_list = sorted(self.__sound_dict.keys())

        self.__list = wx.ListBox(panel,pos=(20,20), size=(250,150))
        for i in self.__sound_list: self.__list.Append(i)
        self.__list.Bind(wx.EVT_LISTBOX,self.__on_click)

        #wx.TextCtrl(panel,pos=(10,10), size=(250,150))

        self.SetTitle("Soundboard")
        self.Show(True)

    def __on_click(self,event):
        event.Skip()
        name = self.__sound_list[self.__list.GetSelection()]
        filename = self.__sound_dict[name]
        print("now playing %s" % filename)

    def __quit(self, e):
        self.Close()
def main():
    app = wx.App()
    windowClass(None)
    app.MainLoop()

main()
