Greetings,
I just realized that statictext controls do not linewrap (boo, hiss)...
And I do need to wrap the text, can someone give me some suggestions on where to look for a solution (methinks I will have to write my own class or function)?
Thanks,
Scott
NOTE: the text object's width cannot be changed. I have it set for 240,
height is -1.

Wrapping might make it in to 2.6. There has been a bit of discussion about it in the last couple days.
In the meantime the way to do it is to measure the words in the text with GetTExtExtent and insert \n's to break the lines wherever you calculate the best spots would be.

Thanks Robin.
Here is my solution for the next newbie...
text = "This is a test of a very long string that may have no end in sight, no end at all, it just keeps going on and on. Old Woman 'I don't like spam!'"
...
ftext = self._formattext(text)
label = wx.StaticText( self.panel2, -1, ftext, size=(240, -1))
...
def _formattext(self, text, max=240):
# dc.GetTextExtent("This is a test")
#(84, 16) width in pixels, height in pixels
dc = wx.ScreenDC()
ftext, j = '', ''
w = 0
li = text.split()
for i in li:
j = ' '.join([j, i])
w, h = dc.GetTextExtent(j)
while w <= max:
break
else:
j.strip()
ftext = '\n'.join([ftext, j])
j = ' '
j.strip()
ftext = '\n'.join([ftext, j])
return ftext

Hmm. I seem to recall making a couple minor tweaks to this
file, but I can't find the original anywhere. I should have
added a note that's it's been modified from the above version.
