Having said that, can you indicate the reasons for wanting support for this? This is just to clarify the requirement

[db0321]

I am trying to send files via share sheet on Mac with OS Ventura 13.3. The ShareItems demo seems to work with texts and images, but not with files. An empty share sheet appears when I try to share file. I think the problem is in unit DW.ShareItems.Mac in procedure Share in line LActivityItems.addObject(TNSFileWrapper.Alloc.initWithURL(LURL, 0));
I think thar LURL needs other type of container to appear in share sheet.

OK, thanks.. I'll look into it

[db0321]

Thank you ... also, it would be great to be be able to use share sheet in Microsoft Windows as well.

Regarding Windows, please see this. If you know of a close equivalent, please let me know

It seems to me that Windows.ApplicationModel.DataTransfer could do the similar thing on MS Windows, i.e. access share sheet panel. It initiates the user interface for sharing content with another app programmatically.

Where IDataTransferManagerInterop is alternative for desktop applications

https://learn.microsoft.com/en-us/windows/apps/develop/ui-input/display-ui-objects#for-classes-that-implement-idatatransfermanagerinterop

and static class DataTransferManager is for UWP apps

I think the problem on macOS may be that TNSFileWrapper is not needed, i.e. the line instead of

  LActivityItems.addObject(TNSFileWrapper.Alloc.initWithURL(LURL, 0))

should be:

  LActivityItems.addObject(LURL);

I'll test later this evening, but you might also like to try

[db0321]

I have just found out that this works for me:

LActivityItems.addObject(TNSitemProvider.Alloc.initWithContentsOfURL(LURL));

the share sheet appers correctly

[DelphiWorlds]

Thanks.. I'll incorporate the change

[db0321]

If possible, I would also suggest to replace line

FPicker.showRelativeToRect(MakeNSRect(0,,0,0,0), LView, CGRectMinYEdge); // <----- Might need to adjust the values in MakeNSRect

with this code

mR.TopLeft:=aControl.LocalToAbsolute(pointf(0,0));
mR.BottomRight:=aControl.LocalToAbsolute(pointf(aControl.Width, aControl.Height));
FPicker.showRelativeToRect(MakeNSRect(mR.Left, LView.Bounds.size.height-mR.Bottom, mR.Width, mR.Height), LView, CGRectMinYEdge);

where mR is TRectF

to position the share sheet below the aControl

Closing as the requirements have been met, other than the request for Windows support, which is now in this issue.
