[Pharo-project] Paint gradients rectangles on #onDraw: method

by nullPointer

Well, IÂ´m continue working on a Grid widget. My old grid was very slow in load data. I changed the old mechanism of columns and rows ( each row was a panel with cells in tableLayout ) by #onDraw: mechanism, painting the cells and contents of it. Now is incredible much more faster. I believe than another people with more knowledge could do more fast too. Now my next problem is implement the "styles" of widget. I need paint gradient rectangles, for color of rows , alternate rows, cells etc. Is possible do that with #onDraw: mechanism? exists some previous example? Many thanks for the answer; regards. -- View this message in context: http://n4.nabble.com/Paint-gradients-rectangles-on-onDraw-method-tp1587597p… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

Re: [Pharo-project] [Seaside] Google Summer Of Code 2010 news!!!

I know the deadline approaches, however- how does the community feel about a project to implement a real demonstration system (along the lines of defunct Sushi store)? Presumably in Seaside, but whichever framework the community/mentor/student decided on. With a nice interface using (again presumptively) jQueryUI to give a pleasant end-user experience. Similarly implementing a persistence solution. The idea is to present potential newcomers to Smalltalk with a viable stack that could be picked up as is, to give a starting point for developing web applications. Potentially they could simply make a hosted copy, on the same server. The idea would be that on the various examples page, you could access an e-commerce site running a Smalltalk technology stack. Ideally really selling something Smalltalk related, (proceeds to eg ESUG), maybe also an Amazon affiliate page . If you liked it, you could copy the whole project, change eg your Paypal details, change your products, and be in business. (Obviously there are real world considerations - this is the concept). And coders looking for examples would see code that was fully completed, not onClick: (... some alert saying you clicked but no real example of how to handle it, eg how to transfer the order line details to the payments server). I think it would do wonders for the take-up of Smalltalk. If people like the idea in general, I'm happy to write up the brief. I don't think i'm the right person for the mentor, but you know who you are ;) For the student, they would get experience in implementing the application itself , as well as assembling the stack. They could be the next Auctomatic founders. Do people think it's useful for me to develop a proposal? Cheers, ..Stan PS I realise that picking a component as part of the stack is fraught with possibilities of offending supporters of an alternative project.

Andreas, I will give that a try. I think it should be active by default, but it won't matter too much once I modify the shortcuts on a few boxes. Other wish list items would be to have a similar option on Linux and to ensure that the contents of the log are concatenated vs. replaced with each crash. Thanks!!

The VM pops up the output console, writes a lot of (probably useful) information to it, and then promptly exits. The issue you're seeing is caused by a recursive MessageNotUnderstood error. You can easily recreate this by doing the following: ((ProtoObject subclass: #Bummerator instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'Kernel-Objects') superclass: nil; new) bummer. The reason why that doesn't result in a regular crash.dmp is that the support code (which catches the crashes and writes the dump) isn't involved at all. The interpreter just quits. Contrast this with, say the result of an FFI crash: (ExternalLibraryFunction name:'' module: '' callType: 0 returnType: ExternalType void argumentTypes: #()) setHandle: ((ExternalAddress new) at: 1 put: 1; yourself); invoke This does generate a crash.dmp since the support code can catch the problem. However, to catch the former issue you can run the vm with -log: <logfile> which will contain the resulting output. > The rebuttal: if it has time/ability to write information all over part of the screen, it can open a file and make sure it leaves a trace of what happened. Right? The current vms (Windows and Linux) appear to be totally disinterested in logging crashes, and that needs to change. They do if you tell 'em to.
