Detailed Description
The SoQtCursor::CustomCursor class is used to specify bitmap data for
SoQtCursor custom cursors.
Member Data Documentation
- SbVec2s SoQtCursor::CustomCursor::dim Size of cursor data. Can be anything
- from 1 pixel wide and high, up to maximum 32 pixels in each dimension.
- SbVec2s SoQtCursor::CustomCursor::hotspot Position of cursor hotspot, ie
- 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>). - unsigned char * SoQtCursor::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. - unsigned char * SoQtCursor::CustomCursor::mask See doc of
- SoQtCursor::CustomCursor::bitmap.
