Re: [Pharo-project] question about mouse gestures

by StÃ©phane Ducasse

Fernando Please do not restart from scratch the code of nathanael was good. Have a look at the comments... :) I asked nathanael to get an image so that we can demo it. I should reping him He went to show to MIT and samsung research lab what he did What would be nice to do is to understand how we can hook Genie with the new event architecture of Pharo. Alain should release the event hierarchy of sophie so that we include it.

Re: [Pharo-project] [squeak-dev] Re: Alien vs. FFI benchmarks (Re: Trying to load ALienOpenGL into 4.1 alpha...)

by Fernando olivero

Hi Igor, at least for me because i didn't have to play with primitives and plugins. Even though i can, because i created a couple of them. But i really liked that you can easily code everything in smallttalk, using the Alien abstractions, and reify the library and the methods in the image.

Thanks Marcus, i will look at them and see if its worth reusing or starting from scratch. For example, i want to be able to delete windows or shapes by drawing an X (or a scribble) above them.

[Pharo-project] How to easily intercept messages sent to ALL objects ?

by Mariano Martinez Peck

Hi folks. I want to intercept (and do something) for all objects. I know few approaches, for example: 1) using method wrappers (implementing run: aSelector with: arguments in: aReceiver) I can wrap all compiled methods of all classes and there I have the receiver. 2) become all objects to some kind of hacky object that stores the original object and that redefines the doesNotUnderstand: But in 1) I need to change all CompiledMehtod of all classes. in 2) I have to become all the objects to another object Then my question is, is there an easier way to intercept all messages send to all objects from the image side (not going to vm) and with a lower cost ? And if going to vm, how ? Thanks. Mariano
