MobileRead Forums - View Single Post - Why did Add Existing Files Dialog UI change?

KevinH · 08-06-2025, 12:06 PM

Okay, I have created testing builds with the new PreviewFileDialog used for Sigil's Add Existing.

It adds a thumbnail pane to the normal non-native QFileDialog that shows both image and text file preview thumbnails of the selected file.

Also, to kill two birds with one stone so to speak, I have added in a new environment variable called:

SIGIL_NO_CUSTOM_DIRECTORY_ICONS

If this environment variable is set, no Custom file icons are used which should help speed up things when networked drives with lots of files are used.

It is only useful when non-native file dialogs are used.

I have posted these testing builds (the macOS ones are signed but not notarized) to my personal github repo here:

https://github.com/kevinhendricks/Bu...nMac/releases/

The files you want are called:

Sigil-testing-Windows-x64-Setup.exe
Sigil-testing-x86_64.AppImage
Sigil.app-testing-Mac-arm64.tar.xz
Sigil.app-testing-Mac-x86_64.tar.xz

If you use Windows or Mac or the AppImage, please try Sigil with Add Existing to exercise this new Dialog and see if you like the new Thumbnail Preview (you may have to resize the dialog once).

If you use network drives with lots of files, please try setting the new environment variable:

export SIGIL_NO_CUSTOM_DIRECTORY_ICONS=1

and see if using this option helps speed up access to your network drive if it has lots of files.

If you build your own on Linux, you should see no changes. All should work as before. But I would love to have that confirmed.

Please let me know what you think?
