Sameple application for drag and drop

Hello,

We build graphical applications for Windows that use drag and drop to execute
actions. We call apis like ImageList_BeginDrag or ImageList_SetDragCursorImage
to add essentiel informations when an element is dragged that detail what will
happen when it is dropped.
This works fine on Windows, on Ubuntu (Ubuntu 19.04, Wine 4.9 32-bit via
PlayOnLinux) but not on macOS (macOS Mojave 10.14.5, Wine 4.9 32-bit via
PlayOnMac).

On macOS no image is displayed when the element is dragged.

Here attached is a sample 32-bit executable you can use to reproduce the
problem.

I tested with Wine 4.8 staging too, this makes no difference.

Is there something we can do to work around this? (modules to add with
WineTricks, or use other Windows apis, use another format for images, etc.).
Any help will be appreciated.

Regards,

Michel Terrisse

Hi.

I believe it's a known issue on macos. As far as I know application can't draw
over desktop on macos, and that's how dragging images are implemented on
Windows. I'm afraid you'll have to use something else to indicate dragging
operation, like changing mouse cursor or something like that.
