Hello,

please use kfm-devel@kde.org to contact the konqueror developers
(as noted on http://www.kde.org/mailinglists.html)

Great ! ;)

Yes and no. Konqueror has a fullscreen mode, as you have certainly seen,
and you can activate it with DCOP, doing
dcop konqueror  'konqueror-mainwindow#1' activateAction fullscreen

However the user will be able to exit the fullscreen mode using the right-mouse-button,
but you can easily disable that using konqview's enablePopupMenu(false).
Hmm, but how to get hold of the KonqViewIface dcop interface ? I think you need to
call dcopObject() in the KonqView::KonqView constructor, after m_dcopObject=0.
Whoever added that dcop call is certainly on kfm-devel and will be able to comment,
hopefully ;)

I'm not too sure how you could do that, either.
If you were using two konqueror views (a splitted window), you could use KonqView's openURL.
With an HTML frameset and HTML frames, it's all one view as far as konqueror
is concerned. You could then use some javascript to change the location
of one frame, but I'm not sure how to activate javascript code from a DCOP call.
Anyone ?

Note that you could simply modify the code, add a dcopinterface to khtml_part,
with a single "executeScript" method, that allows to do that. Or a dcop call that
changes the url of the frame directly, to avoid any javascript in the middle.

Hehe, I know that since IBM is sponsoring hardware for KDE development ;)

Thanks for your interest in Konqueror,
David.
