by Alex Schenkman

Hi List, Where do I find a web client to be able to query a web API? I would need also to create XML for the queries and parse the XML answers. Pointers to relevant packages is are appreciated. Thanks!

Re: [Pharo-users] Laying out Morphs with submorphs outside their bounds

by Sean P. DeNigris

Now that I think about it, the question is really: how does one create a morph that is made up of multiple non-overlapping morphs with no background?

Laying out Morphs with submorphs outside their bounds

by Sean P. DeNigris

I created a ThoughtBalloonMorph seen here (think of a cartoon if you can't see the image): http://forum.world.st/file/n3376956/Screen_shot_2011-03-15_at_March_15%2C_2… It is an invisible morph with three submorphs: * an EllipseMorph with an embedded TextMorph * two small CircleMorphs leading from the thinker to the thought. The problem is that the #bounds of the Morph is 0@0 (for the invisible Morph). Thus, when I add it to a PasteUpMorph with #shrinkWrap resizing, the submorphs are not taken into account and may be cut off, as seen here: http://forum.world.st/file/n3376956/Screen_shot_2011-03-15_at_March_15%2C_2… What's the best way to overcome this? Thanks. Sean p.s. if you're not viewing this on Nabble, did the images work?

Re: [Pharo-users] Transferring variable values to another image

by DougEdmunds

Let me change the scenario a little, using a class instance variable. 1. start with two clean images, image1.image and image2.image. 2. install the Contact Manager classes from http://www.pharocasts.com/2011/02/pharo-gui-with-polymorph.html into image1. 3. run the program "ContactListEditor open" and populate the database with some entries, i.e., "Fred Flintstone", "Barney Rubble", "Wilma Flintstone". Those entries are stored in the Contact class instance variable 'database'. 4. fileout the Category "Contact Manager" from image1.image. 5. open image2, and filein "ContactManager.st". 6. run "ContactListEditor open" in image2, the database is empty. How do I transfer the contents ("Fred Flintstone", "Barney Rubble", "Wilma Flintstone") stored in the Contacts class instance variable "database" from the image1 into image? -- View this message in context: http://forum.world.st/Transferring-variable-values-to-another-image-tp33559… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Yes, you need to write an initialize method on a class that initializes the class variable. When you load a class into your image, an initialize methods on the class side is executed by the loading machinery. Another question is whether you really want a class variable or a class instance variable. I'll leave that for you to decide. Andrew
