Hello, Remember: every time you execute "pharo-ui" you are invoking the UI (as the last part of the name says). If you want to NOT have the UI, you need to execute "pharo" : ./pharo Pharo.Image eval RunGtk execute BUT: this will not work because the image will evaluate "RunGtk execute" and then will exit (because it will evaluate it as a script). To avoid that you need to execute: ./pharo Pharo.Image eval --no-quit "RunGtk execute" That will work as you want. BUT, this is not how executing Spec applications is envisaged : I guess you defined an application (a children of SpApplication?) where you set your backend to make it a Gtk application ? and you have override #start to do something like (MyPresenter newApplication: self) openWithSpec ? In that case, you just need to define in your application class (say is named MyApplication) : MyApplication class >> applicationName ^ 'gtkapp' then, is enough to say: ./pharo Pharo.image run gtkapp which would be the "canonical" way to do it :) Esteban On May 1 2021, at 1:12 pm, kmo <voxkmp@gmail.com> wrote:
After not lookng at it for I while, I tried the Gtk Spec bindings again on my Xubuntu desktop and - this time - they worked. I was able to open a new window using Spec-Gtk, the latest headless VM and the latest Pharo 9. (Many thanks to all concerned).
But I've immediately hit the same issue as I've raised before with SLD support (OSWindow) - it seems impossible to open a Gtk window without the whole Pharo IDE being shown as well.
If I run the following command line - ./pharo-ui Pharo.Image eval RunGtk execute I get the Pharo IDE and a GTK window opened If I run ./pharo Pharo.Image eval RunGtk execute I just get the string RunGtk returned. No window opens. I presume this will work some time in the future. Otherwise what's the use of Spec-Gtk (or OSWindow for that matter)? You might as well just use Spec on Morphic.
