Detailed Description

The SoWxCursor::CustomCursor class is used to specify bitmap data for SoWxCursor custom cursors.

Member Data Documentation

bitmap

unsigned char * SoWxCursor::CustomCursor::bitmap

The size of the array of bitmap data should be equal to (width+7)/8*height, as each cursor pixel is specified with just two bits, one in the bitmap array, one in the mask array.

The bitmap and mask bits should be laid out as follows:

B=1 and M=1 == black
B=0 and M=1 == white
B=0 and M=0 == transparency
B=1 and M=0 will give undefined results for some platforms, so avoid.

dim

SbVec2s SoWxCursor::CustomCursor::dim

Size of cursor data. Can be anything from 1 pixel wide and high, up to maximum 32 pixels in each dimension.

hotspot

SbVec2s SoWxCursor::CustomCursor::hotspot

Position of cursor hotspot, i.e. the pixel of the cursor which is considered to be the "pick point" when interacting with the canvas or widgets.

The hotspot position should be specified relative to the uppermost, leftmost corner (which is position <0, 0>).

mask

unsigned char * SoWxCursor::CustomCursor::mask
