Graphics-Centric UI Capability?
Locked
 
|
hello all,
i have been nabbling about the list archives, trying to figure out the right class to use for providing a scrolling graph pane on which i can draw shapes.
suppose i were to take UITheme(class)>>exampleWindowWithToolbars and want to turn that into a simple Paint Program.
what would i put in place of the StandardWindow>>newTextEditorFor:getText:setText:getEnabled: message send?
are there any simple Paint Program examples i start with?
thanks for any pointers!

Caution: this is *not* the answer to your question; I
will be waiting to see what the experts say on the subject. One thing I
_can_ tell you is that it is often a good idea to write graphics-producing code
in terms of a canvas such that it can draw on "anything" (display, image
file and printer come to mind) using the device resolution to scale things
correctly. I have long been amazed that people create (in Dolphin speak)
their own views when an image presenter would the job given a "background"
bitmap.
There are always exceptions, but IMHO you should at
least consider drawing on a Form and displaying that in a appropriate morph, or
whatever the gurus suggest. I hope that makes at least some
sense.

Because you have some graphs but they do not use Polymorph. Now once you find please advertise it. It is really important to raise the level of knowledge on the community :) > > thanks for any pointers! > > delbert > _______________________________________________ > Pharo-project mailing list > [hidden email] > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project _______________________________________________ Pharo-project mailing list [hidden email] http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project |

Oops sorry for the dumb post.. (im using my friend laptop and not very
handy with keyboard) There is a generic morph, which made specially for scrolling views which not fit fully within display. ScrollPaneMorph or ScrollableMorph (don't remember exactly) the purpose of this morph is provide a scrollers , while you can embed any view within it, having any dimensions and which can be controlled/changed dynamically. 2009/9/12 Igor Stasenko <[hidden email]>: > t > > 2009/9/12 <[hidden email]>: >> hello all, > >> i have been nabbling about the list archives, trying to figure out the right >> class to use for providing a scrolling graph pane on which i can draw >> shapes. >> >> suppose i were to take UITheme(class)>>exampleWindowWithToolbars and want to >> turn that into a simple Paint Program. >> >> what would i put in place of the >> StandardWindow>>newTextEditorFor:getText:setText:getEnabled: message send? >> >> are there any simple Paint Program examples i start with? >> >> thanks for any pointers! >> >> delbert >> _______________________________________________ >> Pharo-project mailing list >> [hidden email] >> http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project >> > > > > -- > Best regards, > Igor Stasenko AKA sig. > -- Best regards, Igor Stasenko AKA sig. _______________________________________________ Pharo-project mailing list [hidden email] http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project |

thanks for the reminder, Bill, i will keep device-independence in mind, without losing the understandability of a basic example.
