Why not? But I hate separators. It is the only big thing I hate in KDE is all 
these separators lines everywhere... I prefer the Gnome way of not using 
them.

I think so. But they advice not doing that in the QT documentation. It is not 
a good idea at the moment, as masks don't have antialiasing in X11 at the 
moment. So your transparent label will be drawn without antialiasing.

This is a QT limitation: button picture is always aligned to the left, even if 
the language is rtl written!. I don't know if it is different in QT4, but I 
can't implement that at the moment.

You don't have to handle all the tags QT uses. Just the presentation ones are 
useful. It seems that you did that...

Here are the few things I modified since 1.9.19:

* I added a "ToolBox" boolean property to the Window class. When this property 
is true, the NET WM window type property is set to "utility", and the KDE 
window manager displays a small window title box instead of a normal one. And 
the tool window is iconified with the main window. This is managed by the QT 
library. If you don't that this feature in GTK+, I added a function in the 
x11.c file to do that by setting directly the window manager property.

* I added a "EndOfLine" property in the stream class, so that we can choose if 
a stream uses a Unix end of line ('\n'), a Macintosh one ('\t') or a Windows 
one ('\r\n'). This end of line feature is used by PRINT, and LINE INPUT.
