Re: [Pharo-users] Writing a GUI - Where to start?

by Mun Mun

Hi everyone, Nobody mentioned Polymorphic. My understanding is that both Spec and Polymorph are built on top of Morphic. I only looked at code example and brief tutorial for both of them, but it seemed to me that Polymorph was easier to grasp: it's quite obivous in the code where and how the widgets are built. I have trouble understanding how the job is done in Spec. On the other hand, Spec seems to have a lot of users in this mailling list. To sum up this thread with many different options proposed, what would be the right path for a newbie like me ?

The TestRunner is usually a better choice in this case, no?

Scaled PNG image

by Hilaire Fernandes

Hello, In Pharo 2.0 (true in 1.4 as well), it looks PNG bitmap are wrongly rotated or scaled when they contain alpha transparency. In the example bellow with the joined bitmap, the alpha gray color are rendered darker when the imagemorph is scaled or rotated. Sqeak does not suffer this problem | dir morph transform form| dir := FileSystem disk workingDirectory parent. morph := (ImageReadWriter formFromFileNamed: (dir / 'bubble.png') fullName) asMorph. transform := TransformationMorph new asFlexOf: morph. transform smoothingOn ; angle: Float pi / 3; scale: 1. transform openInWorld Thanks Hilaire -- Dr. Geo http://drgeo.eu

How to discover which test fails (pharo 2.0)

by Davide Varvello

Hi! I'm on Pharo 2.0. When I run a bunch of tests I usually select a lot of packages from Nautilus and click cmd-t to run them, but unfortunately if one test fails, only a yellow box in the lower left appears and it's time consuming to look for which test fails in which package. I'd love to have the good old dialogs with all the failing tests. Is there a way, in the configuration, to have them back?

Thanks, i checked that out from some digging. Actually all my protocol run over TCP/IP so i cannot do most, but im taking in care move to UDP or maybe one of the Real time options.

If your sockets are connection oriented (it is. TCP) using IP Multicast won't be an option. Multicast was made with Datagrams in mind instead of Packets. Though there was a multicast solution that numbered the datagrams to request retransmission in case of packet loss. Regards, Esteban A.
