# Other field creations here....

self.Sfield1 = wx.TextCtrl(id=wxID_SEARCHBROWSERSFIELD1,
name=u'Sfield1', parent=self, pos=wx.Point(144, 80),
size=wx.Size(216, 21), style=0, value=u'')
self.Sfield1.SetToolTipString(u'')

self.staticText1 = wx.StaticText(id=wxID_SEARCHBROWSERSTATICTEXT1,
label=u'Customer N\xb0', name='staticText1', parent=self,
pos=wx.Point(32, 80), size=wx.Size(83, 16), style=0)
self.staticText1.SetForegroundColour(wx.Colour(255, 255, 255))
self.staticText1.SetFont(wx.Font(10, wx.SWISS, wx.NORMAL, wx.NORMAL,
False, u'Verdana'))
self.staticText1.SetToolTipString(u'')
self.staticText1.SetBackgroundColour(wx.Colour(0, 0, 128))
self.Sfield1.SetFocus()


Why isn't the focus set to SField1 ???????

wx.TextCtrl does not have a member/method SetFocus() and has to get it from it's parent like a wx.Frame or wx.Panel.

So put the wx.TextCtrl on a wx.Panel or wx.Frame and it will work!

# 3 editboxes on a frame

import wx

class MyFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, -1, 'wx.TextCtrl and SetFocus()', size=(400, 150))
        self.SetBackgroundColour('green')
        
        self.edit1 = wx.TextCtrl(self, -1, value="", pos=(10, 10), size=(300, 25))
        self.edit2 = wx.TextCtrl(self, -1, value="", pos=(10, 40), size=(300, 25))
        self.edit3 = wx.TextCtrl(self, -1, value="", pos=(10, 70), size=(300, 25))
        
        self.edit2.SetFocus()  # editbox is on a frame so this works

        # show the frame
        self.Show(True)


application = wx.PySimpleApp()
# instantiate class MyFrame
window = MyFrame()
# start the event loop
application.MainLoop()

I did the same thing using the Boa Constructor program ...

# in the source display select "Edit" and "Add simple app"
# this way all code is in one file

Thanks a lot for this boa example. When I try it, it works and the focus is initialy placed in the second entry control, which I asked. But now I noticed that the TAB key to navigate between the controls don't work.
And I still don't see , if in a later stade of development, we want to insert a textcontrol between 1 and 2, because one was forgotten, how we can do this.

I'm used to tkinter where all this 'seems' a lot easier, I could be wrong of course but is it that difficult to create a standard windows application with wx ?

Sorry, putting components on a frame was the simplest solution to your original problem. Normally, I put the components on a panel which gives the highest flexibility uncluding moving the focus with a tab key. Here is the boa generated code ...

# In Boa Constructor select "New" "wx.Frame" 
# in the source display select "Edit" and "Add simple app"
# this way all code is in one file
# now add the panel and drop the three editboxes on the panel

#Boa:Frame:Frame1

import wx

def create(parent):
    return Frame1(parent)

[wxID_FRAME1, wxID_FRAME1PANEL1, wxID_FRAME1TEXTCTRL1, wxID_FRAME1TEXTCTRL2, 
 wxID_FRAME1TEXTCTRL3, 
] = [wx.NewId() for _init_ctrls in range(5)]

class Frame1(wx.Frame):
    def _init_ctrls(self, prnt):
        # generated method, don't edit
        wx.Frame.__init__(self, id=wxID_FRAME1, name='', parent=prnt,
              pos=wx.Point(332, 135), size=wx.Size(400, 190),
              style=wx.DEFAULT_FRAME_STYLE, title='Frame1')
        self.SetClientSize(wx.Size(392, 150))

        self.panel1 = wx.Panel(id=wxID_FRAME1PANEL1, name='panel1', parent=self,
              pos=wx.Point(0, 0), size=wx.Size(392, 150),
              style=wx.TAB_TRAVERSAL)
        self.panel1.SetBackgroundColour(wx.Colour(0, 128, 0))

        self.textCtrl1 = wx.TextCtrl(id=wxID_FRAME1TEXTCTRL1, name='textCtrl1',
              parent=self.panel1, pos=wx.Point(16, 16), size=wx.Size(344, 24),
              style=0, value='textCtrl1')

        self.textCtrl2 = wx.TextCtrl(id=wxID_FRAME1TEXTCTRL2, name='textCtrl2',
              parent=self.panel1, pos=wx.Point(16, 56), size=wx.Size(344, 24),
              style=0, value='textCtrl2')

        self.textCtrl3 = wx.TextCtrl(id=wxID_FRAME1TEXTCTRL3, name='textCtrl3',
              parent=self.panel1, pos=wx.Point(16, 96), size=wx.Size(344, 24),
              style=0, value='textCtrl3')

    def __init__(self, parent):
        self._init_ctrls(parent)
        self.textCtrl2.SetFocus()  # parent is panel, focus and tab work now


if __name__ == '__main__':
    app = wx.PySimpleApp()
    wx.InitAllImageHandlers()
    frame = create(None)
    frame.Show()

    app.MainLoop()

I find boa too frustrating for simple stuff and do it from scratch in my DrPython IDE. A similar code will look like this ...

# 3 editboxes on a panel
# when panel is the parent the tab key switches to the next control

import wx

class MyPanel(wx.Panel):
    def __init__(self, parent, id):
        wx.Panel.__init__(self, parent, id)
        self.SetBackgroundColour("green")
        
        self.edit1 = wx.TextCtrl(self, -1, value="", pos=(10, 10), size=(300, 25))
        self.edit2 = wx.TextCtrl(self, -1, value="", pos=(10, 40), size=(300, 25))
        self.edit3 = wx.TextCtrl(self, -1, value="", pos=(10, 70), size=(300, 25))
        
        self.edit2.SetFocus()  # editbox is on a panel so focus and tab-focus-move work
        
app = wx.PySimpleApp()
frame = wx.Frame(None, -1, "wx.TextCtrl and SetFocus()", size = (400, 150))
# instantiate class MyPanel
MyPanel(frame,-1)
frame.Show(True)
app.MainLoop()

Thanks for the quick answer !

Actually what you're saying is that BOA makes it complicated ans I agree, you code looks realy a lot simpler for doing the same thing...

Rony

Boa code not only looks more complicated, but on simple apps when you reload suddenly the frame designer goes out and leaves you stuck! There are other frustrating behaviours that I hope will be corrected in later more stable versions of the boa program. I keep templates of basic wxPython code (non-boa) and start from there.

Edit: Have to eat crow! Figured out the problem with the disappearing frame designer button. Don't add any comments above the line

#Boa:Frame:Frame1

boa does not like that!!! The line looks like a comment, but is actually a directive and has to come first! Boa is in my good graces again!

Just a little note on the Tkinter GUI. It is simpler than wxPython, but so is the appearance of the controls, they look a little dated! Some people call them ugly!

I think wxPython has a much steeper learning curve due to the clumsiness of the tutorial examples. Manual notations seem to laps back to wxPython's C++ origin, a little confusing at best.

Note: The first wxPython book is supposed to appear in January 2006 "wxPython in Action" by
Noel Rappin and Robin Dunn.
