I just released PhotoTeleport0.12, which includes thefeature mentioned in the title of this blog post. Given that it took me sometime to understand how this could work with Qt, I think it might be worthspending a couple of lines about how to implement it.
In the target application
The first step (and the easiest one) is about adding the proper information toyour .plist file: this is needed to tell MacOS what file types are supportedby your application. The official documentation ishere,but given that an example is better than a thousand words, here's what I had toadd to PhotoTeleport.plist in order to have it registered as a handler forTIFF files:
This is enough to have your application appear in Finder's 'Open with…' menuand be started when the user selects it from the context menu, but it's onlyhalf of the story: to my big surprise, the selected files are not passed toyour application as command line parameters, but via some MacOS-specific eventwhich needs to be handled.
And for the record, PhotoTeleport is not an electron app:-) It's just that I need the browser to perform the OAuth authentication - I've thought the possibility of using the user browser, but that makes the experience rather worse for the user, in that he needs to copy and paste codes from the browser to the app. Download PhotoTeleport 0.10 software from our fast and free. software download directory.
By grepping into the Qt source code, I've found out that Qt already handles theevent, which is then transformed into aQFileOpenEvent. Thedocumentation here is quite helpful, so I won't waste your time to repeat ithere; what has hard for me was to actually find that this functionalityexists and is supported by Qt.
Providing: various desktop, open source, cross-platform applications: Mappero Geotagger is a photo geotagging application; PhotoTeleport is a tool to upload photos to different services at once; Imaginario is a photo manager application. PhotoTeleport Graphics: no valid OpenPGP data found Photopea Graphics: Photopea in AppImage: spooknik MIT no valid OpenPGP data found PhreshPlayer AudioVideo: Electron based media player. Phreshhh NOASSERTION.
In the source application
The above is only half of the story: what if you are writing an applicationwhich wants to send some files to some other application? Because of thesandboxing, you cannot just start the desired application in a QProcess andpass the files as parameters: again, we need to use the Apple LaunchServicesso that the target application would receive the files through the mechanismdescribed above.
Unfortunately, as far as I could find this is not something that Qt supports;sure, with QDesktopServices::openUrlExternally() you can start the defaulthandler for the given url, but what if you need to open more than one file atonce? And what if you want to open the files in a specific application, and notjust in the default one? Well, you need to get your hands dirty and use someMacOS APIs:
PhotoTeleport is a photo uploader supporting simultaneous uploads to multiple services. But it doesn’t limit itself to upload bare picture files: each photo is accompanied by its caption, description and tags (according to each site’s capabilities) in order to maximize its discoverability.
In Imaginario I've saved this into a macos.mmfile, added it to the source files, and also added the native MacOS librariesto the build (qmake):
You can see the commit implementing allthis,it really doesn't get more complex than this. The first parameter to theMacOS::runApp() function is the name of the application; I've verified thatthe form /Applications/YourAppName.app works, but it may be that morehuman-friendly variants work as well.
