Hi all I am a newbie and want to create a skin for my application . Please help , it is urgent . My problem is that the skin do not show .
Code :
START BITMAP Mobile.mbm
	HEADER
	TARGETPATH \system\apps\Mobile
	SOURCEPATH ..\gfx
	SOURCE c24 screen.bmp //pic size 128,340
	SOURCE c24 screen1.bmp //pic size 128,128
END
Code :
_LIT(KTextureBitmap,"z:\\system\\apps\\Mobile\\Mobile.mbm");
/*Macro for changing the input texture coordinate values from
   GLubyte [0,255] to GLbyte [-128,127]. See more info below. */
#define tex(u,v) (GLbyte)( (u) - 128 ) , (GLbyte)( (v) - 128 )

	{
	    /* top */
	    -1,  -1, 
	    1, -1 ,	    
	    1,	1,  
	    -1,  1
	};
/* Define indices for drawing the triangles. The color of the square
 *  is determined by the color of the last vertex of the square.*/

	/* up */
	0,1,2,
	/*down*/
	1,2,3
};

	{
	    /**** */
