[Pharo-users] SDL2 and fork

Hello everyone, I tried to use the SDL2 binding to Pharo to create a very basic 2D application (just some sprites and events) and it worked great. The issue I have is that when I start my application, as long as I have an active SDL window, I can't use my Pharo image anymore (it freezes). To solve

This is strange, I don't know exactly how the SDL event processing can influence the main window events. >>> Maybe this has something to do how we look for new events in the SDL2DisplayPlugin. >>> For me the call to SDL_PumpEvents looks unnecessary, maybe this is the cause? >>>

[Pharo-users] MouseWheel events

Hello everyone, I have a question about MouseWheel events in Pharo. On Linux, when I use the wheel of my mouse the event I get in return is an instance of MouseWheelEvent : *" [(606@633) mouseWheel Character arrowDown CTRL 33261828 nil] "* When I press "CTRL + ArrowUp" or "CTRL + ArrowDown" on m

[Pharo-users] SDL plugin ?

Hello, I am currently playing with OSWindow and I am wondering what the "SDL plugin" is in the OSSDL2Driver ? When I downloaded the latest linux VM + image I got a library called libSDL2DisplayPlugin but how can I get this plugin for windows ? Is it possible to get the source code too ? Thanks, M

[Pharo-users] Moving the HandMorph

Hello everybody, Is there a way to move the position of the cursor (the HandMorph) by passing commands to it ? I tried things like "ActiveHand position:" or "ActiveHand moveToEvent:" but nothing worked for me. Thanks, Matthieu

Re: [Pharo-users] Moving the HandMorph

Hello again, Just for the record, the EventRecorder source code allowed me to solve my problem. It is apparently not possible to move the main HandMorph but you can create a new secondary one and move it wherever you want ! Thanks again, Matthieu 2015-05-12 17:59 GMT+02:00 Matthieu Lacaton

[Pharo-users] PharoCommonTools methods

Hello everyone, It's probably a silly question but there is something I don't understand in the PharoCommonTools class. There are many methods in this class that i can't find in the image. For example, *PharoCommonTools >> workspaceTool* refers to "*self workspace*" but I can't find any method na

[Pharo-users] Slice for a non Pharo package ?

Hello, I reported a bug on Athens here : https://pharo.fogbugz.com/f/cases/15640/ I also created a slice to solve it by following the Pharo fogbugz video tutorial. But then I realized that Athens is not present in Pharo/main so it would not make sense to commit the slice into the Pharo Inbox. Wh

[Pharo-users] NativeBoost and variadic functions

Re: [Pharo-users] Announcments vs Events schism

It seems to me that sometimes the difference is a bit blurry. I used to consider announcements like some kinds of user-generated events, but I may be wrong here :/ I'll use SDL as an example because this is the technology chosen for Pharo. In SDL the concept of announcement does not exist. However

Re: [Pharo-users] FileLocator problem?

Windows 7 uses "aliases" for these directories. It is the way different languages or owners are handled. For example in French you can see your music directory as "Ma Musique" but the real name used in paths is actually "Music". As Craig said, the default paths for these directories are : "C:\User
