: Everything works fine with default mode (landscape mode). However, when I try
to use either Right or Left portrait mode, the server fails on an assertion in
fblin16.c:
nano-X: fblin16.c:90: linear16_drawhorzline: Assertion `x2 >= 0 && x2 <
psd->xres' failed.
I added some traces to the server, and recompiled/reran it. The actual values
are:
linear16_drawhorzline: x2=319, xres=320
linear16_drawhorzline: x2=319, xres=320
// n lines like the previous ones, these calls blank the background with the
default color. The important value is xres that equas 320 pixels.
InitializeWindowSystem(): initialising...
->connected to Nano-X server...
initTimers()...
PixType is 5
InitializeWindowSystem()...OK
linear16_drawhorzline: x2=95, xres=10
nano-X: fblin16.c:90: linear16_drawhorzline: Assertion `x2 >= 0 && x2 <
psd->xres' failed.
// Bang! : xres has been reduced down to 10. Why ??
Emmanuel - can you send the sample program that causes this error?
Are you using a widget set or direct nano-X programming. The
portrait mode orientation should work completely fine with one
major exception: Microwindows doesn't yet handle converting
pixmaps when switching portrait modes. Everything else should
work fine.
: BTW, I noticed that the C compiler rejects the drivers/kbd_null.c file, since
a function is declared with some parameters and implemented with others
parameters:
I think the proper syntax of line kbd_null.c:12 should be
static int NUL_Read(MWKEY *buf, MWKEYMOD *modifiers, MWSCANCODE *scancode);
yes - this is correct, I'll fix it in CVS.

Greg
Thanks,
Emmanuel.
