What I’m trying to do is launch an application (GZDoom) by dragging and dropping the files I want it to launch with onto its application launcher, which I’ve placed on the icons-only task manager for easy access. Under Windows, this would launch gzdoom’s internal launcher with said files prepared, but under Plasma instead a copy launches for each of the file dragged, which isn’t quite what I’m after.
Is there a way to replicate the behaviour I’m used to from under Windows in Plasma, or am I better off learning a 3rd-party gzdoom launcher instead?
You can achieve this by associating your application with the file types and by specify in a .desktop file that the program can have input parameters.
For instance in kate:
It has:
Exec=kate -b %U
Where %U is replaced by urls that are passed to this launcher. (the -b has no importance)
And
MimeType=text/plain;inode/directory;
Says kate can open text files and directories.
This isn’t necessary for your use-case, but it will make dolphin be able to know this application can open those files.
You can put the .desktop file in ~/.local/share/applications
