[Oroborus-user] Kiosk mode: zero pixels pixmap

[Ferran Jorba]

Hi,

I'm using oroborus as a minimalistic window manager for our
Debian kiosks at the libraries of our university.  Previously,
for Netscape 4.x, I was not using any window manager, but when
switching to Phoenix (now Firebird), I'm forced to use one
(see http://bugzilla.mozilla.org/show_bug.cgi?id=78928).

What I'm trying is to design a theme where the icons are
"invisible", either using a 1x1 pixels (as it works now)
or, better, a 0x0 pixels.

Note that I did now nothing about xpm format 24 hours ago, but
after some googling, I handcrafted this (possibly incorrect)
1x1 file:

---
/* XPM */
static char *color[] = {
/* columns rows colors chars-per-pixel */
"1 1 1 1",
". c black",
/* pixels */
".",
};
---

Then, in my kiosk theme, all the *.xpm files are symlinked
to this pixel.xpm file.  This sort of works, but the titlebar
somewhat appears at top, and it is clickable.

Now, I'm trying to create a 0x0 or 0x1 pixels file.  Yes, I
know that it is gemetrically impossible, and it shouldn't be
allowed.  Any combination I try gives me errors like that:

---
OROBORUS: X Error (0): BadValue (integer parameter out of range for operation).
OROBORUS: X Error (0xc00002): BadGC (invalid GC parameter).
OROBORUS: X Error (0): BadValue (integer parameter out of range for operation).
OROBORUS: X Error (0xc00004): BadGC (invalid GC parameter).
OROBORUS: X Error (0): BadValue (integer parameter out of range for operation).
OROBORUS: X Error (0xc00006): BadGC (invalid GC parameter).
OROBORUS: X Error (0): BadValue (integer parameter out of range for operation).
OROBORUS: X Error (0xc00008): BadGC (invalid GC parameter).
OROBORUS: X Error (0): BadValue (integer parameter out of range for operation).
OROBORUS: X Error (0xc0000a): BadGC (invalid GC parameter).
---

However, on screen, the result is perfect, with no icon
anywhere, not even at the titlebar.

Can anyone please give me any advice on how to accomplish
a completely invisible theme?

I'm on Debian Woody (stable), so my oroborus is 1.14.0-8.

Thanks,

Ferran
