Description clarenze 2022-01-16 10:01:17 UTC

I would like to propose to add an option to display the preview on the second screen (if available). I.e. when you doubleclick a thumbnail, the preview window should opens up on the second screen. When you select a differnet thumbnail, the picture on the second screen shall be updated. This is different to the Fullscreen-mode, as the fullscreen mode
- always opens on the default screen - you have to manually configure it to show on the other screen
- is not synchronized with the selected thumbnail
- does not allow zooming via ctrl-mousewheel

Hi,

Try Slideshow tool, it can preview items with multi-screen support.

But that is only for viewing, isn't it? If I want to work with the images (e.g. go roughly through the collection to remove bad/unwanted/duplicate images), I can't do that with the slide show, can I ?

So I second the wish to show the preview window on a second screen (even if simply being able to undock it and move it there manually), so that 
a) have a larger preview
b) have a larger list of thumbnails (instead of the narrow strip on top of the preview window)

Yes some operations are possible from the slideshow tool:

Thank you for the prompt reply.

However, I couldn't figure out which shortcut can delete an image (to trigger the "trash can" button). 

And it is not synchronized to the thumbnail view. So I don't get a "preview" that/how many similar pictures are upcoming. 

And while I can _show_ image properties/ratings, I cannot manipulate them in the slide show mode, correct? 

Thus, I would appreciate a view on a second screen that shows the image preview but also allows to "work" with the image (rate, rotate, provide context menu, delete, ...)

"Delete" Shortcuts : Look in Settings/Configure Shortcuts dialog.

Labels can be modified with mouse on a corner of slideshow view, if option is enable in Slideshow configure dialog.

Tags can also assigned with a shortcuts normally, if they are configured win Tag properties dialog. See Tags Manager for details

The Online documentation for the Slideshow tool explain well how it can be used:

https://docs.digikam.org/en/slideshow_tools/slide_tool.html

For the Shortcuts, there are listed here :

https://docs.digikam.org/en/setup_application/shortcuts_settings.html

And for the Tags Manager :

https://docs.digikam.org/en/main_window/tags_view.html#tag-manager

I close this file now.
