Dragging files to .app no longer loads them
« on: August 14, 2025, 01:37:15 am »
Hola,
 
With Lazarus 4.0 and earlier, I could (individually) drag .srt (SubRip), .vtt (WebVTT), and .itt (iTunes Timed Text) files onto my .app, and it would open them without any issues on OS X El Capitan (10.11.6).
However, after updating Lazarus to 4.2, I now get an error: The document “[example]” could not be opened. App cannot open files in the “Text file” format.

Is it possible that something has changed internally in Lazarus?

Thanks in advance!

Hi
Hmmm, have you checked for BOM (B)yte(O)rder(M)ark in the srt files?!?
There are BOMs for utf8 & utf16 BE/LE...

When I compiled my app with Lazarus 4 or earlier, it worked. I think the problem started with Lazarus 4.2. The message I get is from macOS as soon as I drag the file over the .app.

Did you set all the path correctly?

I haven't changed anything in my app, I just recompiled it with the new Lazarus and it stopped working. What should I check?

Maybe something changed with macOS El Capitan compatibility?

Could it have something to do with 32-bits vs 64-bits?
You could also check if all your links/path are still correct.

I only use 64-bit, everything is still the same. The only change was updating Lazarus.

I've written a subtitle editor and don't have this problem. I've implemented the drage & drop function a few years ago in Lazarus 3.x and now I'm using Lazarus 4.4 and everything still works fine. You are using the 'ondropfiles' event?

"Could it have something to do with 32-bits vs 64-bits?"

On Windows I noticed that seizing drag and drop behavior for 32Bit compiling, but not for 64Bit compiling. Perhaps Mac Lazarus apps have the same problem?
