Squeak on tablets
by OpenSlate ChalkDust 20 Jul '19

20 Jul '19

Sorry, I have been away from this scene for several years but returning for a fresh look. Especially interested in running Squeak on portal computers, including tablets. Is anyone working on an Android port? How about battery life? I was running Squeak on a Sony tablet PC around the time Win 7 came out, and battery life was very short. Appreciate your suggestions and looking forward to more interaction. The link below is to my old but still up web site. Yes, it needs renovation. -- Gary Dunn Open Slate Project http://openslate.net/

can't run 32 bit squeak 5.2 on 64 bit OS (Debian 10)
by Ralph Boland 19 Jul '19

19 Jul '19

I am able to run Squeak 5.2 (64 bit) on 64 bit Debian 10 but when I try to run Squeak 5.2 (32 bit) I get the following error: ~/Downloads/Squeak5.2-32/Squeak5.2-18229-32bit-201810190412-Linux$ squeak.sh Using /home/rocky/Downloads/Squeak5.2-32/Squeak5.2-18229-32bit-201810190412-Linux/bin/squeak... could not find display driver vm-display-X11; either: - check that /home/rocky/Downloads/Squeak5.2-32/Squeak5.2-18229-32bit-201810190412-Linux/bin//vm-display-X11.so exists, or - use the '-plugins <path>' option to tell me where it is, or - remove DISPLAY from your environment. Aborted My assumption is that some 32 bit libraries are missing but that's only a guess. If my assumption is correct can anybody tell me what libraries I need? I think it's a red herring but it is noteworthy that there is a double slash ('//') immediately before the 'vm-display-X11.so exists ... in the error message. I assume this is just a typo by the person who created the error message. I tried the -plugins advice but it didn't seem to work. Perhaps I did it wrong. When I ran Squeak 5.2 32 bit on Debian 9 (32 bit) it ran fine. Any advice on how to resolve this problem much appreciated. I can provide any additional information requested. Ralph Boland

Handling events on NCAAConnectorMorph subclass
by Nicola Mingotti 14 Jul '19

14 Jul '19

Hi, I am using package Connectors. I made my own connectors subclassing NCAAConnectorMorph [say it is called MyCon] Now, I would like the aMyCon to change its color to black when it is connected to other 2 morphs and be orange when it is not fully connected. I saw there is NCAAEventsHandler with stateConnected and stateDisconnected but I don't understand how i can use these two events. I tried defining inside the class MyCon methods like these, copying what I do for mouse events: ------------ handlesStateConnected: evt ^ true stateConnected: evt self color: Color black ------------ It does not work. How should I do ? I don't find an example. Are NCAAEventsHandler events recognized by NCAAConnectorMorph ? I would like my event handler to add up to what the default event handler does, not substituting it. bye Nicola

Invisible Connectors
by Nicola Mingotti 12 Jul '19

12 Jul '19

Hi, I am just starting with Squeak, it is something completely different from all other programming languages/environments I saw before. Very interesting. I am using Squeak 5.2 for Linux (under FreeBSD-12 Linux compatibility layer), it works. Coming to the question. I found this package called Connectors. I tried to connect some Morphs with "Curvy Arrow" and it all works fine, clicking on the GUI. But, if I try make a connector from the Workspace I can't see the line and I don't understand well what happens. For example, If i run this code ----- https://wiki.squeak.org/squeak/1773 ----- green := Morph new color: Color green; position: 100@200; openInWorld. red := Morph new color: Color red; position: 100@300; openInWorld. c2 := NCAAConnectorMorph new connectStartTo: green ; connectFinishTo: red ; openInWorld. ------------------------------------------ I see the two rectangles but I don't see the connector. I tried to inspect madly the "c2" object but I can't find how it is different from a Curvy Arrow that is actually displayed. I installed Connectors via SqueakMap, the latest release I saw (I can't see the number now, probably because the package is already installed). Any ideas ? bye Nicola
