GUI in Python using wxGlade

[diffuser78]

I recently tried a hand at wxGlade and was happy to see it designs a
GUI for you in minutes. I am a newbie Python coder. I am not completely
aware of GUI programming.

I can easily make menubars etc but I am not too sure sure how to get
more windows poppping to get more information. I mean when you click
something, a new windows would open and ask for input like that. Since
I am using wxGlade and wxPython....can you suggest me a quick tutorial
for GUI programming.

Every help is appreciate,

Thanks

Without having time to go into a full, the way to proceed with Glade
(unless I am mistaken) is to design each window independently of the
others, and to use a button press in one window to create an instance of
another type of window.

Good luck!

I am pasting my code. I created a small little GUI without any
functionality as of yet. I wanted to ask few questions on that.

If I click on any of the items of the File Menu, say I click on "Open
config File", I want a new windows to come up.

My questions is when I create a new Frame/Windows in wxGlade, will it
be wxFrame or wxMDI Frame......whic h one should I choose and why ?

I am not completely aware of all the small tools that wxGlade gives and
how to place them.
Any kind of help is greatly appreciated.

Thanks

As I already said I'm a bit to busy to help with specifics right now.
Two places you might go for help:

1: http://www.holdenweb.com/PyConTX2006/wxPythonIntro.pdf

The introductory tutorial I gave at PyCon TX 2006

2: Email to wx************* ****@lists.wxwi dgets.org

There's a fairly friendly community who will take your code as
evidence you are trying to help yourself and explain the basics
as necessary.

I am a newbie. I was looking for some code where I could a list of
different items from a file and display it in a list box. Then give a
user the capability to select some.

Basically, reading and writing to a file and displaying them in
different widgets...thats something I am looking for. If anybody can
point me to some good example tutorials...I will be greatly helped.

Thanks,

Every help is appreciated

Have you tried looking at the code in the wxPython demo? In the ListBox
control demo, it populates a ListBox with items from a list, but you
could easily translate that into reading from a file, I think. Here's
the full code in case you don't have the demo:


import wx

#---------------------------------------------------------------------------

# This listbox subclass lets you type the starting letters of what you want to
# select, and scrolls the list to the match if it is found.
class FindPrefixListB ox(wx.ListBox):

choices=[], style=0, validator=wx.De faultValidator) :
wx.ListBox.__in it__(self, parent, id, pos, size, choices, style, validator)
self.typedText = ''
self.log = parent.log
self.Bind(wx.EV T_KEY_DOWN, self.OnKey)
def FindPrefix(self , prefix):
self.log.WriteT ext('Looking for prefix: %s\n' % prefix)

if prefix:
prefix = prefix.lower()
length = len(prefix)

# Changed in 2.5 because ListBox.Number( ) is no longer supported.
# ListBox.GetCoun t() is now the appropriate way to go.
for x in range(self.GetC ount()):
text = self.GetString( x)
text = text.lower()

if text[:length] == prefix:
self.log.WriteT ext('Prefix %s is found.\n' % prefix)
return x

self.log.WriteT ext('Prefix %s is not found.\n' % prefix)
return -1
def OnKey(self, evt):
key = evt.GetKeyCode( )

if key >= 32 and key <= 127:
self.typedText = self.typedText + chr(key)
item = self.FindPrefix (self.typedText )

if item != -1:
self.SetSelecti on(item)

elif key == wx.WXK_BACK: # backspace removes one character and backs up

Did you paste any code ?

Also the link for the next message is not working .....
