Hello All,
I’m probably making a really stupid mistake
here! I’ve tried playing around with ScrolledPanel and can’t
get the scrolling to work (which is a bit of a disadvantage with such a
control).
The following program always blows up at the statement “self.panel.SetupScrolling()”.
The error I receive is:
IndexError: tuple index out of range
Traceback (innermost last):
File “d:\MyProjects\multi_frames\test_app.py”,
line 1, in ?
import wx
File “d:\MyProjects\multi_frames\test_app.py”,
line 46, in ?
app = TestApp()

self.panel.SetupScrolling()

line 62, in SetupScrolling
w, h = sizer.GetMinSize()
File
“C:\Python24\Lib\site-packages\wx-2.6-msw-unicode\wx_core.py”, line
909, in getitem
def getitem(self, index):
return self.Get()[index]
If I remove the statement the window displays without
scroll-bars. Any help would be gratefully appreciated (including
admonishments for making dumb mistakes).
For the record I’m running this using Python 2.4.2 and
wxPython 2.6.2.1 (Unicode).
Cheers!!
Here is the sample code:
import wx
import wx.lib.scrolledpanel as scrolled
class MainFrame(wx.Frame):
def
init(self, parent):
wx.Frame.__init__(self,
parent,-1, “Test Scrolled Panel”)
self.panel
= scrolled.ScrolledPanel(self, -1)
self.panel.SetBackgroundColour(wx.WHITE)
self.item_boxes
= []
self.items
= []
self.main_box
= wx.BoxSizer(wx.VERTICAL)
for
i in range(0, 33):
lbl
= wx.StaticText(self.panel, -1, “Field:”, style=wx.ALIGN_RIGHT)
txt
= wx.TextCtrl(self.panel, -1, “”, style=wx.TE_MULTILINE)
item_box
= wx.FlexGridSizer(cols=2, hgap=5, vgap=5)
item_box.AddGrowableCol(1)
item_box.Add(lbl,
0, wx.ALIGN_CENTER_HORIZONTAL|wx.ALIGN_RIGHT)
item_box.SetItemMinSize(0,
50, -1)
item_box.Add(txt,
0, wx.EXPAND)
self.main_box.Add(item_box,
0, border=2, flag=wx.EXPAND|wx.BOTTOM)
self.panel.SetSizer(self.main_box)
self.panel.SetAutoLayout(1)
self.panel.SetupScrolling()
class TestApp(wx.App):
def
OnInit(self):
self.gui
= MainFrame(None)
self.SetTopWindow(self.gui)
self.gui.Show()
return
True
if name == ‘main’:
app
= TestApp()
app.MainLoop()
