minimize to try question

[Wenzhi Liang]

Hi all,

I'm writing a simple GUI app with wxPython and would like to implement
a "minize to tray"
functionality. Did a bit googling and basically found the solution to be:

1. Handle the ICONIZE event to Hide() the window
2. Handle the LEFT_DCLICKE event of the icon to do
    - Iconize(False)
    - Show(True)
    - Raise()

It worked quite well under Windows. But on Linux, when trying to
restore the window, it
sorta flashed back for 1/2 second and disappear again. Is there a
cross platform way of
doing this?

My environment:
python 2.5 + wxPython 2.8.4

Thanks,

[Robin Dunn]

I think we'll need a sample to play with to figure this out.

AFAIK wx.EVT_ICONIZE is also generated when restoring from taskbar.
You should add "if event.Iconized():" before calling Hide()

-Roee.

Thanks for the reply. Here is the code I use:
init()
        self.Bind(wx.EVT_ICONIZE, self.OnIconify)
  self.tbicon.Bind(wx.EVT_TASKBAR_LEFT_DCLICK, self.OnTaskBarActivate)


        def OnTaskBarActivate(self, evt):
                print 'OnTaskBarActivate...'
                if self.IsIconized():
                        self.Iconize(False)
                if not self.IsShown():
                        self.Show(True)
                self.Raise()


        def OnIconify(self, e):
                """ Being minimized, hide self, which removes the program from the
taskbar.  """
                print 'OnIconify...'
                if not self.IsIconized():
                        self.Iconize(True)
                self.Show(False)

Indeed when I double click on the tray icon, I got:

OnTaskBarActivate...
OnIconify...
OnIconify...

Which is a little bit strange. Why is the latter two event triggered?

Regards,

Indeed when I double click on the tray icon, I got:
OnTaskBarActivate...
OnIconify...
OnIconify...

you should only get one  "OnIconify..." when double clicking (and this is what I get on ubuntu). As I said EVT_ICONIZE is also triggered on restore in wxGTK.
In case your code doesn't work try this demo:

import wx

#-------------------------- Create Icon --------------------------
def GetMondrianData():
    return \

def GetMondrianBitmap():
    return wx.BitmapFromImage(GetMondrianImage())
def GetMondrianImage():
    import cStringIO
    stream = cStringIO.StringIO(GetMondrianData())
    return wx.ImageFromStream(stream)
def GetMondrianIcon():
    icon = wx.EmptyIcon()
    icon.CopyFromBitmap(GetMondrianBitmap())
    return icon 
#-------------------------------------------------------------------------
class TestFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, -1, "Test TaskBarIcon")
        
        self.icon = GetMondrianIcon()
        self.SetIcon(self.icon)
        
        self.tbicon = wx.TaskBarIcon()
        
        
        self.Bind(wx.EVT_ICONIZE, self.OnIconify)
        self.tbicon.Bind(wx.EVT_TASKBAR_LEFT_DCLICK, self.OnTaskBarActivate)
 
        self.Show()
        
    def OnTaskBarActivate(self, evt):
        print 'OnTaskBarActivate...'
        if self.IsIconized():
            self.Iconize(False)
            self.Show()
            self.Raise()
            self.tbicon.RemoveIcon()
 
    def OnIconify(self, evt):  
        print 'OnIconify...'
        if evt.Iconized():
            self.Iconize(True)
            self.Hide()
            self.tbicon.SetIcon(self.icon)
 
if __name__ == "__main__":
    app = wx.App("")
    frame = TestFrame()
    app.MainLoop()

That did the trick.  :) Thanks.
