Hi Greg,
I'm sorry I don't remember the details right now, since It was done a while ago.
But I'm pretty sure I tried to #define FLIP_MOUSE_IN_PORTAIT_MODE with values 0
and 1 and none of them did the job of rotating the mouse movements (at least
not completely).
If I knew it should've worked, I'd have spent some more time looking at it, but
it's unlikely that I'll get back to that right now ;-)
Thanks again!

Your solution is fine, but it is hardcoded in the mouse driver and doesn't allow
the display to be rotated differently at runtime. Try changing the value of the
#define in engine/devmouse.c and see whether that works and doesn't require your
hardcoded driver mods.
Regards,
Greg
--------
I don't know it this is the best solution, but I've altered the mouse driver
Read() function like this:
+---- Original code -----+------ Modified Code -------+
| |#ifdef LCD_LANDSCAPE_MODE |
| ... | *dx = delta_x; |
| *dx = delta_x; | *dy = delta_y; |
| *dy = delta_y; |#else |
| ... | *dx = delta_y; |
| | *dy = - delta_x; |
| |#endif |
+------------------------+----------------------------+
This finished the job of rotating the mouse movements. I also apendded the
following lines to my display driver Open() routine:
#ifdef LCD_PORTRAIT_MODE
psd->portrait = MWPORTRAIT_LEFT;
psd->xvirtres = psd->yres;
psd->yvirtres = psd->xres;
psd->orgsubdriver = &lcd_subdriver;
set_subdriver(psd, &fbportrait_left, FALSE); #endif // LCD_PORTRAIT_MODE
but from your description it looks like you've got it done already.
Hope it helps, and if you (or someone else) come up with a better solution
please let me know!
