Hello,
How am I supposed to copy text from a puInput widget to the clipboard ?
Should there be a way to mark text with either the keyboard or the mouse ?
^C seems to do nothing and ^V breaks with :
Program terminated with signal 11, Segmentation fault.
Cannot access memory at address 0x4013cdf0
#0 0x809969f in puInput::checkKey (this=0x8145900, key=22) at puInput.cxx:321
321 if ( ( strlen ( getStringValue () ) + strlen ( puGetPasteBuffer
() ) ) < PUSTRING_MAX - 1 )
(gdb) bt

(gdb)
Seems like puGetPasteBuffer() returns an invalid pointer.

That means, you should be able to copy-and-paste from a puInput to another, but not from a PUI widget to a text field of some X application or vice-versa. - Sebastian |

Yes - that's what I meant...but the mechanisms for cut/paste are quite different between X, Windoze and others. ----------------------------- Steve Baker ------------------------------- Mail : <sjb...@ai...> WorkMail: <sj...@li...> URLs : http://www.sjbaker.org http://plib.sf.net http://tuxaqfh.sf.net http://tuxkart.sf.net http://prettypoly.sf.net http://freeglut.sf.net http://toobular.sf.net http://lodestone.sf.net |

Yes. However, PLIB builds a portable layer around a lot of things that are different between UNIX, Windows and other operating systems, so it would indeed be quite intresting to figure out how to implement copy & paste for Windows, X, MacOS (non-OSX), BeOS ... - Sebastian PS: Germany vs. USA: 1:0 ! |

Yes - exactly. The only problem is that I don't understand *any* of those
mechanisms! Heck - I don't even know how to do it within X. But I think it would
be a valuable addition if someone knows what is needed.
Ob. Cut & Paste anecdote: My son has a 'typing' class once a week at school,
it's really boring rote work and once the children finish the typing
exercise for that day, they get to surf the web or whatever. Since most
of the 'exercises' entail typing the same combinations of letters over
and over until you hit a certain speed rating with some limited number of
errors. Oliver rapidly discovered that the people who wrote the typing tutor
software didn't consider that you could type the exercise once (S-L-O-W-L-Y)
and then use cut and paste to enter the entire thing a second time perfectly
and in about a millisecond! So, Oliver basically spent the entire term
playing on the computer. At the end-of-year awards ceremony, the school
handed out awards for highest Math score, highest Art score, etc, etc...and
lo and behold, Oliver was awarded the Typing award, as he was called up to
collect it, the teacher said something like "Oliver Baker is awarded the
typing certificate for typing...er...this must be a misprint...it says
10,000 words per minute."

...but...Brazil vs. England: 2:1 :-(
