I have a TextCtrl which is set to be multi-line. I have a function
say, updateText(msg), which takes some string and appends it to the
text control...
txtControl.AppendText(msg)
.....however, if the text that I am appending would cause the scroll
bars to appear/or scroll since the text is long the textcontrol appears
to be blank, until you click on the scroll bar...then the text appears.
Any ideas? is this is a sizer problem or a TextCtrl issue??
thanks 10 4069

Don't know for sure, but you can try calling the Refresh() method on the
text control and see if that fixes it.

Didn't make a difference. Not sure what the problem is, I am wondering
if it is a layout issue since that is my weak spot with wxPython.
sizerTextPanel =
wx.StaticBoxSizer(self.sizerTextPanel_staticbox, wx.HORIZONTAL)
sizerTextPanel .Add(self.textPane, 1, wx.ALL|wx.EXPAND, 2)
self.textPanel.SetAutoLayout(True)
self.textPanel.SetSizer(sizerTextPanel )
sizerTextPanel .Fit(self.textPanel)
sizerTextPanel .SetSizeHints(self.textPanel)
sizerMainPanel.Add(self.textPanel, 3, wx.ALL|wx.EXPAND, 0)
not sure if that means anything to anyone :)

Your best bet may be to post to wx************@lists.wxwidgets.org
But one question that comes to mind is, do you not add sizerTextPanel to
sizerMainPanel? I think all sub-sizers should be added to the main
sizer, unless there's some weird reason I don't know of.
If you post to the wxPython mailing list, you might want to include more
of your code so we can see the bigger picture.

well i set the sizer on the textPanel and then I add the textPanel to
sizerMainPanel

Ah, I see. Seems like it may be a sizer issue, since you are adding a
bunch of things together. I noticed that one object you refer to is
self.textPane, is that supposed to be self.textPanel?

no, self.textPane is the actual wx.TextCtrl.
I used a GUI Builder to the layout stuff...perhaps that's my problem :)
is there a good site to refer to for how to use sizers? i am
essentially creating a chat window (textPane is the history of the
chat, then a textCtrl below it for typing a new message and a button
next to the input field and buttons below the input field).

After I watched the screencasts for how Dabo uses sizers, I really
understood them a lot better. I've never used Dabo itself for GUI
design, but the screencast, though it shows them in terms of that
program, still gives a great visual presentation of how sizers work in
general and I suggest you take a look at that: http://leafe.com/screencasts/sizers1.html http://leafe.com/screencasts/sizers2.html
P.S. I suggest you post the full code to the wxPython mailing list. I'll
take a look at it to see if anything strikes me, but also you will have
a ton of other (more experienced) people looking at it too, and I
guarantee they will spot your problem.

Thanks for the good feedback. It took me a while to wrap my brain
around sizers when I first started using them; now I hate working
without them!
Also, I wanted to mention that our visual Class Designer has another
helpful feature: you can right-click control to bring up a context
menu. One of the choices is 'Edit Sizer Settings...', which brings up
a dialog with all the relevant settings in one place. As you change
them in the dialog, the design surface updates so that you can see
the effect of your changes before you commit them. If you don't like
your changes, click 'Cancel' and things return to the way they were
before you started.

thanks for the feedback, I am watching the screencasts, which are
helping already. I think I will try out the Dabo GUI tool since it
uses wxPython...and see if I can get the code I need from it.
thanks

I think you'll be very impressed. Those guys are creating an excellent
tool, and I've found that I can create pretty complicated UIs in a
very, very short time with the Class Designer.
