The scrolling isn't the issue, and I probably need to add the panels to the
AUI pane manager. The text pane scrolls fine in my real application.

What I am trying to do is make the rich text box act like the normal text
box. On my machine, the rich text box (in this application and in my real
application) sort of freezes until I stop updating it, and then it updates
all at once with the scroll bar at the top. The normal text box updates
immediately and scrolls downwards like a log viewer. Do you see the same
effect?

Thanks.

    Hello Robin,

    Yes, I tried both types of RichText, with the same results. Also,
    I forgot
    to mention that the OS is XP Pro, I'm using the latest version of
    wxPython,
    and my project is based on the AUI_Manager.

    I'm not intentionally blocking the event loop. For now, everything is
    running in the main thread (to put these pseudo-dialogs in
    separate threads
    is a future task, but not necessary now). It works fine with the
    TextCtrl.

    I've attached some code that shows exactly what I'm experiencing.
    The app
    starts with two buttons, and they create panes with normal text
    and rich
    text. I'm not using a timer to slow down the updates, but there
    are enough
    lines to see that the normal text display updates with each new
    line and
    always scrolls to the last line. The rich text pane doesn't update
    at all
    until all lines are appended, and the scroll position is at the top. I
    noticed that neither panel will scroll, but that doesn't happen in
    my real
    application, and can be ignored.

    Thanks for taking a look.

    Carl

I test your app but I cant see any difference between both.. only the
richttext button take a little more time to charge, but in both we can
scroll to the bottom with no problem or odd behavior.

I use Ubuntu 8.10, Python 2.5.2 and wxPython 2.8.9.1

It definitely does not scroll on Windows XP. Unfortunately, I don't know
enough about AUI and / or nested panels to understand why...so I'm not
sure which is causing the issue or if that even is the issue. Hmmm

Yes, I do. If I add a wx.Yield() after the AppendText(), you can see items get added to the text box. I noticed in some of my applications where I redirect text to a multiline TextCtrl, I use the wx.HSCROLL style rather than the wx.VSCROLL style. And no, I don't know why I started doing that. I must have gotten it from some other example...

You might be able to work around the issue by messing with the SetInsertionPointEnd() command or just SetInsertionPoint(). Both of these are methods of a TextCtrl.

Ahh, much better. Wx.Yield took care of half the problem. I can start
playing around with the insertion points now.

Thanks very much Mike, and everyone else.

Building on some previous posts, I've attached some code that includes a
"close" button on a floating pane. The event fires, but I can't seem to get
only the pane to close. I just want it to do exactly what it does when I
click on the "x" on the pane (meaning, it just closes the pane, and doesn't
actually delete it).

I thought this would be easy, but I'm missing something. Either nothing
happens, or the entire application closes.

Thanks.

Hi,
did you mean something like:

    def OnClose(self, event):
        print 'CLOSED'
        self._mgr.GetPane("Print Text").Hide()
        self._mgr.Update()

or is it something more complex?

Thank you, it works perfectly.

I can't believe I didn't try that. It never occurred to me that clicking the
'x' is just hiding the pane instead of closing and destroying it.

Thanks again.

You've already discovered wx.Yield, but I should mention that in your sample you *are* blocking the main event loop with your while loops. In other words, events can not be processed while the loop is running for the rich ctrl. The non-rich ctrl appears to work because the native widget is doing the equivalent of a Refresh and Update, but you'll also notice that it's a lot slower because of that.

Sounds good. I wasn't aware that the textctrl was doing an automatic
refresh.

That said, in your opinion, am I using the right tool for the job? I have
played around with the listctrl, and in Report Mode that could give a
similar effect, and the user wouldn't know the difference. I'm always open
to suggestions.

Thanks.

I'm having a problem changing the caption of a pane. In the attached code, I
change the caption after the text is finished printing, but it never seems
to update. I've tried various settings in the AddPane properties, but
couldn't seem to get any further.

There are actually another problem I don't understand as well. One, it never
displays a caption at all until I click on "x" to close the print pane. I
thought my OnClose event did the same thing as the "x", but apparently not.

My print statements show that the caption is changing, and I'm calling the
self._mgr.Update. These are at lines 35-51.

What am I doing wrong?

Thanks.

Hi,
I'm not sure about the reason, but your code works fine, when you dock
the text pane, however, for the floating one the caption isn't
updated.

adding the following lines to OnPrintText it "works", but it seems
quite hackish to me:

self._mgr.GetPane(self.Button.PaneName).Caption('Printing Done')
self._mgr.GetPane(self.Button.PaneName).Dock()
self._mgr.Update() # also not working without an intermediate Update()
self._mgr.GetPane(self.Button.PaneName).Float()
self._mgr.Update()

Hey, good catch. That never occurred to me.

Upon further experimentation, I found that if I leave the "hack" out, the
caption will change when I manually dock it, so it's definitely related to
that somehow. I tried tweaking other properties momentarily to trigger a
caption change, but no-go.

I'll go forward with using this hack for now. There is a "flicker" when the
pane refreshes, but other than that it works fine.

Maybe Robin or someone can elaborate on if there is a different way.

Thanks for your help.
