Re: [Pharo-users] separate native window of same Pharo image

by kmo

it is perfectly possible with OS-Window to create a morphic world and create your own morphic content for it, then display it in a completely different operating system window. This is how I created a simple application which displays geometric "roses" in a separate window to the pharo window. First create your morph. In my case RosesMorph. This can be a compound morph with as many sub-morphs as you like. In this way you can build a complete application interface. Now create a sub class of OSWindowWorldMorph like this: OSWindowWorldMorph subclass: #RosesWorldMorph instanceVariableNames: '' classVariableNames: '' package: 'KMP-Roses Add the following methods to your OSWindowWorldMorph subclass using this code as a model: RosesWorldMorph>>osWindowCloseButtonPressed self delete RosesWorldMorph>>initialize | rosesMorph rosesFrame | super initialize. self layoutPolicy: ProportionalLayout new. self extent: 600 @ 600. self osWindow title: 'Roses'. rosesMorph := RosesMorph new. rosesMorph color: (Color r: 0.13 g: 0.13 b: 0.13 alpha: 1.0). rosesFrame := LayoutFrame fractions: (0 @ 0 corner: 1 @ 1) offsets: (0 @ 0 corner: 0 @ 0). self addMorph: rosesMorph fullFrame: rosesFrame. rosesMorph sticky: true As you can see once you have an OSWindowWorldMorph you can add whatever morphs you like to it. Now you can launch your RosesWorld app in a separate window like this: RosesWorldMorph new open. Hope this helps -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [Pharo-users] separate native window of same Pharo image

by alvaro piorno

Hi, I played a bit with that. I did something like this: window := OSWindow createWithAttributes: (OSWindowAttributes new resizable: false; yourself). window title: title. And then: surface := AthensCairoSDLSurface fromSDLSurface: self window handle handle getWindowSurface Then you can render everything in the surface from Pharo. Is this what you want?. 2018-07-19 8:31 GMT-03:00 Peter UhnÃ¡k <i.uhnak(a)gmail.com>: > Hi, > > did anyone play around with launching a separate native window for Pharo? > > E.g.

It turns out splitting the app over multiple processes is only necessary on iOS 12, which has more severe memory limits. iOS 12 doesn't support OffscreenCanvases in web workers yet, or 2d contexts for OCs, so for now I'm just back in iOS 11, where everything works in one big process (Squeak + A-Frame). thanks, -C -- Craig Latta Black Page Digital Amsterdam :: San Francisco craig(a)blackpagedigital.com +31 6 2757 7177 (SMS ok) + 1 415 287 3547 (no SMS)

Hi Siemen-- > What is the status of Caffeine now - is it production-ready with > Pharo, and how large is a minimal (not development) image with > everything required to run a production system - i.e. what would be > the load time of a Caffeine web app? I'm using Caffeine in production with Squeak; there are a few bugs to deal with in Pharo. Would you like to work together on it? A minimal system is a few hundred kilobytes, depending on the application. The VR app I'm doing now is fairly large and loads in 10 seconds. A small app should take about two seconds. The mini image demo at [1] is a good approximation. Please feel free to join in on Caffeine issues, at [2]. thanks, -C [1] https://squeak.js.org/demo/simple.html#fullscreen [2] https://github.com/ccrraaiigg/ccrraaiigg.github.io/issues -- Craig Latta Black Page Digital Amsterdam :: San Francisco craig(a)blackpagedigital.com +31 6 2757 7177 (SMS ok) + 1 415 287 3547 (no SMS)

separate native window of same Pharo image

by Peter UhnÃ¡k

Hi, did anyone play around with launching a separate native window for Pharo? E.g. I have normal window in which Pharo is, and then I open a separate native window that shows just e.g. Transcript. I know that there are some projects like OSWindow-SDL and OSWindows-UI (using WinAPI), but both of them are aimed at opening windows with non-pharo content, which is not what I want. Any pointers? Thanks, Peter

Re: [Pharo-users] Status of Caffeine

by Siemen Baader

Thanks! My idea was to use it in a similar manner to e.g. Angular, with a full app being loaded into the browser which communicates with a backend API. But this requires the load time to be acceptable.. another direction would be to embed it in a phone gap app and use it to build DOM-based mobile apps. There a larger footprint would be ok. -- Siemen Sent from my iPhone > On 19 Jul 2018, at 11.26, Erik Stel <erik.stel(a)gmail.com> wrote: > > You can find the source at the GitHub-link below.

You can find the source at the GitHub-link below. Craig seems active on this project seeing the number of recent commits. Focus is on creating a live VR-environment. Cool stuff I think . It will run Pharo, but if that means 'production ready'... Small image sizes for production systems/applications is probably a separate topic. Caffeine is a Smalltalk VM written in JS (with some extra's), so image size depends on how small you can make your image. I read in some of the more recent issues that on some mobile devices (based on iOS) the page reloads after switching apps and/or locking the device. This will loose any data currently in the Caffeine app. Craig is working on a solution based on WebWorkers. This probably means: not production ready for mobiles yet .

Status of Caffeine

What is the status of Caffeine now - is it production-ready with Pharo, and how large is a minimal (not development) image with everything required to run a production system - i.e. what would be the load time of a Caffeine web app? Thanks, Siemen Sent from my iPhone
