Re: [Pharo-users] NativeBoost Questions while wrapping FMOD
I really think that NativeBoost MUST HAVE a decent documentation.
It is a central part of Pharo and Igor you should do something about it.
If I would know I would have written a chapter on it but I cannot because I DO
NOT KNOW.

And igor do not tell me that only C programmer should use NativeBoost.
We should focus on our clients and our clients are smart Pharoers that can

Re: [Pharo-users] NativeBoost Questions while wrapping FMOD
However we should acknowledge here that using a FFI, any FFI , in any
programming language has the mandatory requirement of knowing C. I
certainly do believe that documenting Nativeboost is extremely important
for helping people to port C libraries to pharo and making Pharo far more
useful but we should not kid ourselves. Coding with Nativeboost even though
its inside Pharo , even though its smalltalk syntax, even though it has the
tools to make your life easier, its still C coding or even Assembly coding
if you are brave enough to use the inline assembler.
I want to help with documentation the problem is that I dont know a lot of
stuff about Nativeboost besides the basic pointer things I did with
NBOpenGL.

[Pharo-users] Deploying a polymorph app - two questions
I have written a small Polymorph application in Pharo 2.0. I have some questions about deploying it. My app consists of a single morph. I would like to fill the pharo window with the morph and have the morph resize when the user resizes the pharo window. I'm pretty close to what I want. I have made my morph a subclass of FullscreenMorph and it is filling the window nicely. I just need two things. One - I need to change the pharo window title to the title of my application. I have tried DisplayScreen hostWindowTitle and it seems to have no effect. Two - I need to get rid of the Pharo window status bar - the one at the bottom which shows you the various windows, browsers, and workspaces you have open. Can anyone give me some guidance? Thanks. -- View this message in context: http://forum.world.st/Deploying-a-polymorph-app-two-questions-tp4724525.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] [Athens] Finding if a line passes through a specific pixel .
aahhh come on ... I am not THAT lazy :D of course I have searched it before asking. Unless I am blind I see loads of bezier methods, none that detects whether a point belong to a curve. But now you mention it I think I remember squeak was able to do add points to a curve via click or something similar, because thats what I wan to do. So I will take a look at it , most probably there is a method in there that does this. I want the user to click on a curve or line and there a new control point will be placed that will allow the user to shape the line or curve to a finer detail. A standard feature for all vector editors , 3d editors, even image editors. I am sorry if I miss something obvious here, its not laziness , its most likely stupidity or just the fact I am very new with this. This is the first time I try to make a vector editor.Again thank you all for trying to help me, you have done already a lot.

Re: [Pharo-users] Deploying a polymorph app - two questions
Benjamin - Many thanks. Your suggestion of World submorphs do: [:e | e delete ] was just what I needed to get rid of the taskbar. However, DisplayScreen hostWindowTitle does not work for me. I'm not using Spec but surely that should make no difference. Is it a platform bug (I'm on ubuntu 13.04) or are you using pharo 3.0? I'm on pharo 2.0 (there is no WorldModel as far as I can see). So, is DisplayScreen hostWindowTitle broken on pharo 2.0? ken -- View this message in context: http://forum.world.st/Deploying-a-polymorph-app-two-questions-tp4724525p4724550.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Thanks for the attachments I will take a look at them. The time it takes to render the fractal is not the problem.

Probably because you should cache the result you get and not redraw it all the time. You should control when you want to redraw it. So your Morph should hold a form or something like that.

Re: [Pharo-users] [Athens] Finding if a line passes through a specific pixel .
There is some bits which can help you in this regard. The part of it is path tesseleration, which turns any path with complex curves into polygon (which has only straight lines), from there on, i think you can easily calculate the distance between any point and that polygon. Look at AthensCurveFlattener class, and its uses. the entry point is (flattenPath: aPath transform: aTransformation). But be aware that this is not fully integrated yet and subject to change in future. On 23 November 2013 15:20, kilon alios wrote: > aahhh come on ...

A more verbose form is: self nbCallout stdcall; options: #( - optDirectProxyFnAddress optAllowExternalAddressPtr); function: #( NBBootstrapUlong HeapAlloc (ulong heapHandle , 0 , SIZE_T size) ) module: #Kernel32 But be aware though, that this code usually invoked once during code generation, and later no method code is invoked because it just runs a primitive (primitiveNativeCall), and if it succeeds, it just returns with result, without running a method's body. So, nbcall can be changed/extended if you need extra thing at code generation stage, or you want to handle primitive error(s) differently. But not for handling things like function return values (which happens to be a library's error/success code). -- Best regards, Igor Stasenko.
