wxPython - Setting a help string for a button in toolbar

I noticed I can have a help string appear in the status bar whenever I mouse over tools in my toolbar. I cannot find a way to accomplish this with text buttons.

My toolbar creation is similar to

# Make Tool Bar
toolbar = self.CreateToolBar()
# Make Tool Bar Items
# Play
self.addBasicTool(toolbar, "Play",
                  "This is my help string",
                  stuff.image_play,
                  self.OnPlay)
# My Button
btn = wx.Button(toolbar, wx.ID_OPEN, label="TEXT BUTTON ")
btn.Bind(wx.EVT_BUTTON, self.OnButtonPress)
toolbar.AddControl(btn)

addBasicTool just takes the image, scales it to a proper size, creates the tool with AddBasicTool, and binds the tool to the handler.

def addBasicTool(self, toolbar, label, desc, imgPath, handler):
    icon_width=stuff.toolbar_icon_w
    icon_height=stuff.toolbar_icon_h
    size = (icon_width, icon_height)
    img = wx.Image(imgPath, wx.BITMAP_TYPE_ANY).\
                   Scale(*size).ConvertToBitmap()
    tool = toolbar.AddSimpleTool(-1, img, label, desc)
    self.Bind(wx.EVT_MENU, handler, tool)

For the tool, the helper string is set pretty straight forward. I can't find anything to do the same with a button.

This button may just end up being a filler until I get an icon for it, but I'm still curious how helper strings can be done. I could have a handler that sets the statusBar when the mouse is over the button, but I feel like that is already done somewhere. Thanks the help

Basically you'll have to catch the mouse as it moves over your buttons and update the status bar accordingly. It's not very hard. You just need to bind to wx.EVT_MOTION. Here's a simple example:

import wx

########################################################################
class MyPanel(wx.Panel):
    """"""

    #----------------------------------------------------------------------
    def __init__(self, parent):
        """Constructor"""
        wx.Panel.__init__(self, parent)
        self.frame = parent

        test_btn = wx.Button(self, label='Test Button')
        test_btn.Bind(wx.EVT_MOTION, self.updateStatusBar)

        test_btn_2 = wx.Button(self, label='Test Button')
        test_btn_2.Bind(wx.EVT_MOTION, self.updateStatusBar)

        self.buttons = {test_btn: 'Test help string',
                        test_btn_2: 'Another string'}

        main_sizer = wx.BoxSizer(wx.VERTICAL)
        main_sizer.Add(test_btn, 0, wx.ALL, 5)
        main_sizer.Add(test_btn_2, 0, wx.ALL, 5)
        self.SetSizer(main_sizer)

    #----------------------------------------------------------------------
    def updateStatusBar(self, event):
        """"""
        btn = event.GetEventObject()
        if btn in self.buttons:
            status = self.buttons[btn]
            self.frame.sb.SetStatusText(status)



########################################################################
class MyFrame(wx.Frame):
    """"""

    #----------------------------------------------------------------------
    def __init__(self):
        """Constructor"""
        wx.Frame.__init__(self, None, title='Test Help Strings')
        panel = MyPanel(self)
        self.sb = self.CreateStatusBar()
        self.Show()

if __name__ == '__main__':
    app = wx.App(False)
    frame = MyFrame()
    app.MainLoop()
