Html5 and QT applications on koi #help #agl-compositor #koi

Hello everybody,
i am trying to make Web applications coexist with Qt in a single digital ecosystem. Previously using icefish this was possible by including the packagegroup-agl-profile-graphical-html5 in order to integrate WAM and Chromium into the image.
I tried on koi the same thing starting from the agl-demo-platform image, but after the boot splash screen a blank screen appears. From the documentation it seemed to me that both digital ecosystems (Qt ecosystem and Web Apps ecosystem) are able to use the new agl-compositor in a similar way, so there a way to integrate them together in the image in a similar way like icefish? Thanks in advance for your help Fabrizio Di Domenico

Hi Fabrizio,
i am trying to make Web applications coexist with Qt in a singleJust to have all the info, which platform are you testing it on? Do you have some logs you could share? From the documentation it seemed to me that both digital ecosystemsYes, it should be possible to keep doing it. However, as there were changes on the recipes for the demo-platform, we are checking if there's something additional that needs to be explicitly included to be able to run the webapps on top of WAM on that Qt image.

Hi Lorenzo,
thank you very much for your reply. Just to have all the info, which platform are you testing it on? Do you have some logs you could share?I'm testing on h3ulcb-kf machine using koi 11.0.1 and agl-demo-platform as the target recipe with packagegroup-agl-profile-graphical-html5 appended to it. I think the following log fragment shows the issue that i'm facing: The following one is the WAM log: Do you have some hints on where i should start to investigate in order to solve this issue ? Thank you, Fabrizio

Hi Lorenzo,Hi, Judging by your logs it seems you're attempting to use both homescreen and WAM in the same time, which won't work because only one of them (at a time) is in charge/responsible for being a client shell. Please see [1] for a more longer explanation about our current eco-systems/platforms and how do they work. On the same topic, there's nothing stopping running any other regular clients. homescreen is special because it is one that handles the client shell, and same happens for WAM (for web apps). They're both responsible for setting-up panels and backgrounds can not run at the same time. Choose one of them at a time (notice that AppFW would attempt to start them by default -- you could tweak config.xml to avoid that) and you should be fine, though I'm that sure you have a way to switch between apps, when combing platforms (you'll be missing buttons/launcher that performs the switch).

Hi Marius,
thanks for your feedbacks. So if i understand well, there is no way to run Web apps on top of a Qt Image (indeed homescreen implementation using Qt) like it was on icefish, or i am missing somethings else? On the same topic, there's nothing stopping running any other regularWhat do you mean for regular clients? If i will not use WAM (but just homescreen in Qt) and if i will have a web-runtime installed on the image, is it possible for both a generic Qt or Web app to be displayed and executed ? Choose one of them at a time (notice that AppFW would attempt to startthem by default -- you could tweak config.xml to avoid that) and you should be fine, though I'm that sure you have a way to switch between apps,when combing platforms (you'll be missing buttons/launcher that performs the switch).So for my understanding this means that i'm need to install both Qt Homescreen and WAM, then just one of them must be activated at runtime based on the application type that needs to be executed. Is this correct? In this case do i need to have two homescreens, one in html and one in qt in order to perform the switch using the launcher or some other buttons on screen? Moreover, is the config.xml referred to the generic apps or to the homescreens ? Thank you very much Fabrizio

Hi Marius,There is, just not the client shell (homescreen for Qt). Any other client than is not the client shell (homecreen or WAM). AWhat do you mean for regular clients? If i will not use WAM (but just client shell is the client that implements a private extension to specify how we place and order "windows". I mean, you don't need to, you seem to be wanting to have both HTML5 andSo for my understanding this means that i'm need to install both Qt Qt, which is fine. I think you might need to read [1], to understand the role of the client shell and the private extension we have in AGL. You can have both of the installed, but not running at the time. In this case do i need to have two homescreens, one in htmlNo, what I meant is that probably you'll need to amend either homescreen or WAM such that you have a way to switch between different applications (and most likely to start them). For instance, you can have homescreen and start a browser instance (by this I mean chromium but maybe any other html5 app). If the browser is installed like a widget it will automatically show up in the launcher application, and with it you can start it, and, at some later point in time, to switch to it. On the HTML5 side of things, you can have WAM as the client shell, and still use Qt applcations. Where and how you start the Qt applications, interactively using WAM is at this point an unknown to me, as I don't believe we have something similar to what the launcher application does now on the Qt platform.
