Hi,

Do you mean charts and graphs? If so, check out PlotMorph.

Thanks David, I think I need to look at Morphs a little more closely for what I need to do which is to create some graphics (shapes, etc.) and send them to a printer.

Hi Ching.
Morphs draw themselves on Canvases - look at the Canvas class. Typically, these would be FormCanvas which draws to the screen. I think there is a Postscript-capable Canvas subclass. I'm not sure what it's called ("PostscriptCanvas"?). Google for Ghostscript for info on how to print postscript files if you don't have a postscript-capable printer (or if you aren't running Linux). Also try reverse-engineering the print command in the... menus? This will be a good exercise for you. Find the "print" command in a menu somewhere in squeak (probably in a halo menu for a Morph?), and open the halo on the menu itself, select "explore" or "inspect" and poke around to see if you can find where the code for the print command is. Sorry I can't give you specifics; I don't have squeak available right now. Michael.

Hi Michael,
Thanks for the info. Squeak can be intimidating with its wealth of capabilities if you don't know where to look. I will sure be busy checking out your suggestions. Ching

Squeak isn't intimidating. It's cute and fluffy :-P.

Cute, fluffy, true. And powerful.

Hi Ching!
I've been saving the form to a graphic file and then printing that. That way I can use Paint Shop Pro to add all sorts of eye candy before printing. This is in the context of maths problems for remedial teaching - I have a set of classes that create a form and populate it with maths problems, where difficulty and kinds of problems are parameters. Saves me hours each week. Hope this applies in some way, John > Hi, > > I would like to print graphics in Squeak.

HI John,
That's a neat idea. Thanks a lot. Ching On 9/18/07, [hidden email] <[hidden email]> wrote: Hi Ching! _______________________________________________ Beginners mailing list [hidden email] http://lists.squeakfoundation.org/mailman/listinfo/beginners |

If you want to print directly out of Squeak, at least on Windows platforms, I've found the class TextPrinter to be very useful. It is obvoiusly designed to print text reports, but all of the plumbing is there to print out a page of whatever content you want too. However, there will be digging involved.

Also, for "end-user friendly" printing take a look at Sophie which implements platform printing including proper dialogs on Mac and Win. - Bert - _______________________________________________ Beginners mailing list [hidden email] http://lists.squeakfoundation.org/mailman/listinfo/beginners |

Hi
If you want to print a morph, get its form (imageForm message) and use the primitive primPrintHScale of Form class primPrintHScale: hScale vScale: vScale landscape: aBoolean "On platforms that support it, this primitive prints the receiver, assumed to be a Form, to the default printer." "(Form extent: 10@10) primPrintHScale: 1.0 vScale: 1.0 landscape: true" exemple: | cont m length | cont := Morph new. cont color: Color lightBlue. cont layoutPolicy: TableLayout new ; listDirection: #topToBottom ; cellPositioning: #topLeft ; hResizing: #shrinkWrap ; vResizing: #shrinkWrap. #( 'Label A' 'Label B' 'Label C' 'Label D') do: [ :label | m:= Morph new. m layoutPolicy: TableLayout new ; listDirection: #leftToRight ; height: 25. m cellInset: 4. m color: Color random twiceLighter. length := m width + 200 atRandom. m width: length. m addMorphBack: (StringMorph contents: label) . m addMorphBack: (StringMorph contents: length asString). cont addMorph: m. ]. cont cellInset: 4. cont openInWorld. cont imageForm primPrintHScale: 1.0 vScale: 1.0 landscape: true. "(I think it was printh: 96.0 v: 96.0 landScape: false. on an older version)" See also the TextPrinter class (sender of primPrintHScale) hope it helps regards alain "Ching de la Serna" <[hidden email]> a écrit dans le message de news: [hidden email]...

Hi Chris, Bert, Alain. Your info is really appreciated. And Alain's code really makes it easy to understand and use the classes. Thanks a lot, guys.
