[Pharo-project] Socket question (Was Re: Xtreams up to date)
by mkobetic＠gmail.com Jan. 13, 2011

Jan. 13, 2011

I started looking at the Socket failures that I can reproduce and I can't wrap my head around the SocketReadingWritingTest>>setUp. Based on what I know about TCP sockets it doesn't make sense to me. AFAIK to get both ends of a connected TCP connection (lacking a socketpair call) I need 3 sockets. A listening socket, a client socket (doing connect) and finally the server socket that comes out as a result of accept on the listener. So I'd expect to see something like this in the setUp: | data input output listener socket1 socket2 process sync | Socket initializeNetwork. sync := Semaphore new. listener := Socket newTCP. listener listenOn: 9999. process := [ [ socket1 := listener accept ] ensure: [ listener close ]. sync signal ] fork. socket2 := Socket newTCP. socket2 connectTo: (NetNameResolver localHostAddress) port: 9999. sync wait. output := socket1 reading. input := socket2 writing. Surprisingly, the above doesn't work, while many of the Socket tests seem to pass for me despite my brain telling me that it can't possibly. Can anyone shed some light on this for me ? Thanks, Martin

I have seen some things flying around on the mailinglist related indirectly to this issue. Is there a solution ? Thx, Sven

[Pharo-project] about text selection colors in 1.2
by Alain Plantec Jan. 13, 2011

Jan. 13, 2011

Hi all, A friend of mine told me that it was very difficult for him to see the difference between the green and the blue colors. (Color blindness...) So, I would suggest to change the secondary selection color (green) to another color. What do you think ? which color ? Cheers Alain

Tudor Girba >I tried to start from zero and add a new variable (e.g., color) only when I >could not distinguish something If that is true then why do you use the additional blue for activated buttons instead of using a gray one: lightSelectionColor ^ Color gray in your original theme - you can distinguish buttons already using the gray-style gradient (see attached example). However ... all of this is very specific to a particular persons view of the world. As you said you've choosen blue since it is the color of Moose... Bye T. -- GMX DSL Doppel-Flat ab 19,99 Euro/mtl.!

[Pharo-project] Dirty MC Packages in Pharo-1.1.1-OneClickCogVM
by Sven Van Caekenberghe Jan. 13, 2011

Jan. 13, 2011

Yesterday I downloaded Pharo-1.1.1-OneClickCogVM from https://gforge.inria.fr/frs/download.php/27524/Pharo-1.1.1-OneClickCogVM.zip and I noticed it has two dirty MC packages (MethodWrappers and Tests). This is probably a glitch, but not nice and confusion for beginners. Sven

[Pharo-project] How to bundle an application with icons?
by Dimitry Golubovsky Jan. 13, 2011

Jan. 13, 2011

Hi, Suppose I need to bundle a Pharo application (a package) I am developing with some custom icons: is there any "standard"/ agreed-upon method to do that in Pharo? For example the MenuIcons class includes byte strings (automatically I assume) converted from some external PNG files that show up as icons with menu items: which tool can be used to create a class with set of icons for an arbitrary application? If I want to reuse icons for standard actions in my application, which is the proper way to access menu icons other than to directly access these stored images? Thanks. PS Other than the "by example" books (both Squeak and Pharo) which give some basics of building GUI for applications, are there any general guidelines for GUI building in these systems? -- Dimitry Golubovsky Anywhere on the Web
