A tiny correction: [ (Delay forSeconds: 5) wait. image delete ] fork. You may wanna do this in the #startUp method of your class, and register it to the startup list by doing Smalltalk addToStartUpList: YourClass.

Developing a Splash Screen...

by Nelson Pingitore

I am attempting to add a Splash Screen to a Pharo project. I currently use the following to bring up the image: *(ImageReadWriter formFromFileNamed: 'C:\Users\npingito\Documents\Smalltalk\Splash Screen\splash.bmp') asMorph openInWorld * my question is, how can I close this image after a delay, such as after 10 seconds, and is there a better construct to use?

GSoC news: we got 30 proposals, few stats

by Janko MivÅ¡ek

Dear Smalltalkers, Yesterday passed a deadline for students to propose how will they do the projects and we received 30 proposals from 23 students, which is in my opinion quite a nice number and I'm sure we can end up with quite a number of nice projects this year. And what is even more important: new Smalltalkers in community! Next two weeks mentors will review and rank/vote for the proposals, Google will give us a number of stipendiums it will provide and in few days after Friday 20.April we will have a final list of accepted students and their projects. Few stats (numbers of all participating): 32 projects 34 mentors 32 students 30 proposals 23 students wrote proposal Students by Smalltalk skill: 11 None 9 Low 5 Medium 7 High Students from countries: 5 Argentina 5 India 4 Russia 3 USA 2 Chile 2 Czech Republic 2 Malaysia 1 China 1 Croatia 1 Ecuador 1 Egypt 1 France 1 Germany 1 Sweden 1 Ukraine 1 Slovenia Stay tuned!

When I am using a construct such as the following: builder := UITheme exampleBuilder. dialog := (builder newPluggableDialogWindow: 'Example basic controls') useDefaultOKCancelButton. . . . model: nil. builder openModal: dialog. is there another option other than "openModel", to use to open the dialog?

Re: [Pharo-users] Pharo OneClick and Ubuntu 12.04 beta 2 64 bit

by drush66

it was under stupid varioan ;) - installing ia32libs solved the problem. Though mentioning it somewhere on the web page or readme might be a nice touch. And/or giving more informative error message.

Pharo OneClick and Ubuntu 12.04 beta 2 64 bit

by drush66

Ok, I guess I am doing something completely stupid or Pharo 1.3 and 1.4 OneClick do not work on Ubuntu 12.04 beta 2 (64bit)? I get the error: ./pharo.sh: 8: exec: ./Contents/Linux/pharo: not found I guess it has something to do with 32/64 bit libraries that one click tries to use. Since 64bit will be default from 12.04 for Ubuntu, this kind of makes it important.
