And if this just for a graphical clock, a morph with step should be doing the trick. stepTime can be set as well.

Interesting, I got to play around with these, do some async morph animations. -- View this message in context: http://forum.world.st/Intro-to-Microsoft-COM-for-Smalltalkers-tp4917738p491… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

You can write this: ["your code". 1 seconds wait.] fork. Also look at project TaskIt https://github.com/sbragagnolo/taskit. It provides many high level scheduling capabilities.

of course Pharo has an event queue, we call them announcements. That implies however that you want the code to execute as soon as something else happens. If you don't , fork and delay should be enough. With fork you dont need to wait for othet tasks to finish to execute your code, it will just put it to a thread and execute it concurently. If you want the code to run as soon as other tasks finish then of course you dont use fork.

Re: [Pharo-users] Pharo on my Ubuntu laptop :3

by Dimitris Chloupis

Oh I forgot to tell you , you can customize the theme too the easy way, install my project Nireas from Package Browser , then go to settings and choose the Nirea theme, a blue theme will appear however this is not the end of the story , open world menu go to Ephestos -> Nireas, a GUI will appear , you will see two buttons with number 1 and number 2 , 2 will revert back to dark theme, use the other buttons to choose the colors you want. Currently there is no way to save the theme separately so you will have to save your image to keep the theme. You will have to close and reopen your windows to see the new theme. You can also do many other customization like changing the icon of the pharo executable and its name.

Re: [Pharo-users] Intro to Microsoft COM for Smalltalkers

a JavaScript timeout is a function that takes a block and a period of time, and after this period of time, puts the block at the end of the event queue, to be executed as soon as the runtime is done performing the tasks in front of it. I am not sure if Pharo has an event queue, so it's a bit harder to do it(since without one you can't ensure only one thing happens at a time, and strange things can happen). That said, in simplest terms, imagine writing a clock app for Pharo, which updates time every second, in JS this would be done by setting an interval that ticks every 1000ms, and each time places the callback function(block) at the end of the event queue.
