wxWidgets apps have no window decorations when run via NX

[Ian Macdonald]

Hi,

NX is a remote desktop protocol; we're using FreeNX on the Ubuntu server
and OpenNX on the Windows clients. We can start a desktop and then our
application successfully, but if we try to start our application
directly, we get windows without borders, whereas other apps (xterm,
firefox, chrome, etc) work correctly when started in this way.
Experiments have shown this problem applies to all Wx applications we
can find, e.g. all our applications, the wxPerl demo app, Audacity, etc.

See image illustrating problem at Loading Image...

Background:
We've got an application written using wxPerl which has been
successfully put into production on a local LAN. We wish to use the NX
remote desktop technology to improve display performance across longer
distances (New Zealand clients, Australian servers).

Thanks for any suggestions,

What is you host and the client running?
Which version of wxWidgets you are trying?
Did you try the wxWidgets sample to run?

Thank you.

Hi Ian,

See image illustrating problem athttp://i.imgur.com/FTbH03g.jpg

Well firstly let me say congratulations. It took me ages to find a way
of achieving this. I'm only sorry it wasn't what you were looking for.

You haven't mentioned your other systems. Can I assume they show the
correct Windows decorations?

I eventually found this:

eon Aurorae no buttons by FRUiT

Under:

System Settings>Workspace Appearance>Windows Decorations>Get New
Decorations.


It also achieves no decorations, which is what I wanted.

To do the opposite:

1) Try to apply a windows decorations with the style you want and see if
that helps.
2) Otherwise, I suspect it's not a wxPerl issue but a wxWidgets issue. I
find that when I choose


System Settings>Application Appearance><Something>


That my choices are not reflected in my applications in wxPerl, or if I
do a build of the samples in wxWidgets, they too do not show the correct
settings.


So you may want to try the google group called wx-users.

If you do get an answer please post it here. I'd also like to have more
flexibility over my decoration options.


I hope that helps.


Regards

Steve
