button positioning

andrea.gavana · November 21, 2005, 5:58pm

Hello Nicholas,

try the following code and see if it does what you expect...
Basically, I have added a stretchable spacer *before* the buttons by doing:

h_sizer.Add((1, 0), 1, wx.EXPAND)

And then I have declared that your h_sizer should be expandable in the
horizontal direction inside the v_sizer, with:

v_sizer.Add (h_sizer, 0, wx.EXPAND)

Now the spacer occupies all the left space and the buttons are "right
aligned". Is this what you meant or am I missing something?

HTH.

Andrea.

import wx

class UserPanel (wx.Panel):

def __init__ (self, parent, id):
wx.Panel.__init__ (self, parent, id)

v_sizer = wx.BoxSizer (wx.VERTICAL)

list = UserList (self, -1)
v_sizer.Add (list, 1, wx.EXPAND|wx.ALL, 5)

h_sizer = wx.BoxSizer (wx.HORIZONTAL)

h_sizer.Add((1, 0), 1, wx.EXPAND)

addButton = wx.Button (self, -1, "Aggiungi")
h_sizer.Add (addButton, 0, wx.ALIGN_RIGHT)

delButton = wx.Button (self, -1, "Cancella")
h_sizer.Add (delButton, 0, wx.ALIGN_RIGHT)

v_sizer.Add (h_sizer, 0, wx.EXPAND)

self.SetSizer (v_sizer)

self.Layout ()

class UserList (wx.ListCtrl):

  def __init__ (self, parent, id):
    wx.ListCtrl.__init__ (
      self, parent, id, style = wx.LC_REPORT|wx.SUNKEN_BORDER|wx.EXPAND)
    self.populate ()

  def populate (self):
    self.InsertColumn (-1, "Username")
    self.InsertColumn (-1, "Nome")
    self.InsertColumn (-1, "Cognome")
    self.InsertColumn (-1, "Telefono")
    self.InsertColumn (-1, "Fax")

class MyApp (wx.App):

  def OnInit (self):
    f = wx.Frame (None, -1)
    p = UserPanel (f, -1)
    f.Show ()
    return True

app = MyApp ()
app.MainLoop ()

You do not need to use a stretchable sizer. Just align the h_sizer instead of
the controls it contains. See example below.
