Hello!
I want to know more for printing possibilities
in QNX RTP 6.01 in text’s mode and graphic’s mode.
How can printing during using of standard widgets
like PtMultiText and PtPrintSel (and make preview)or
anothers.What about *.ps and *.phs files?
Can I find somewhere open source examples?
In Help, there is not enough information about printing!
Thank You in advance!
