Hello,

with the latest (or next to latest) version, kernic does not work anymore.
The sources are here.

I like it, it's a thumbnailer that uses a script to create thumbnails.
The script must be in the PATH and named stripPicture.


I use it to create the mkv thumbnails from attached images and to display only one image based on their names for the folders.

Dolphin should have desktop files in /usr/share/kservices5/ or ${HOME}/.local/share/kservices5/.

Desktop file eg:

Code: Select all

[Desktop Entry]
Type=Service
Name=Folder only one image (Keneric)
X-KDE-ServiceTypes=ThumbCreator
MimeType=inode/directory;
X-KDE-Library=keneric
CacheThumbnail=true

Now Dolphin always sees the desktop files in the thumbnailers tab of the configuration.

But, I guess kernic is not called because, stripPicture is not running now and ~/.cache/keneric isn't created.
I tried to use a simple echo to in file in the script file but nothing is created.


I need it, any idea what the problem is?
I tried to rebuild also the sources...


Thank you very much and sorry for my english !
Have a nice day.


EDIT:
Before:



After apt dist-upgrade:

Hello, happy new year

No one has any ideas?

Maybe the post can be moved to System & Utilities or Dolphin?

You would have to ask the developer of the utility about this, perhaps it needs to be updated to work on more current Plasma systems.

The keneric library might need to be rebuilt against the current system libraries, or something along those lines?

I sended a mail 2 weeks ago without reply.

I don't use c++ but the code is simply and seems OK.

I have tryed to change it to just create a folder but nothing happens...

I rebuilded it many times.

Is the location of the script files (~/.local/bin) in your $PATH?

The script is in /usr/bin/

If I edit the sources of keneric and I leave only a folder creation, the folder isn't created.

So I guess the problem is before the script execute.

I tryed to create the simplest thumbnailer but without success...

keneric.h :

Code: Select all

#ifndef KENERIC_THUMBNAILER_H
#define KENERIC_THUMBNAILER_H

    virtual Flags flags() const;
};

bool Keneric::create(const QString &path, int width, int height, QImage &img)

    QString kenericDirectory("/tmp/keneric/");
    QDir directory(kenericDirectory);
    directory.mkpath(".");

    fstream my_file;
    my_file.open("/tmp/keneric.txt", ios::out);
    my_file << "super test";
    my_file.close();

    fstream my_file2;
    my_file2.open("/home/hizoka/keneric.txt", ios::out);
    my_file2 << "super test";
    my_file2.close();

    return false;
}

But no file or folder created...

Arf...

There is no problem with the thumbnailers...

It's a f***ing bug into dolphin....

If I delete the PreviewSettings group in the dolphinrc file, everything works...
