Enhancement: Better Drag & Drop

[dreamsyntax]

What

The current Drag & Drop install mod feature has very little area where you can drop a mod. Leading to some users thinking the feature is broken.

A user would intuitively try to drop the mod within the list of Mods in Configure Mods window.

Drag-N-Drop-Current.mp4

Proposal

• Allow drag & dropping anywhere within the MainWindow and automatically detect the context (external file? -> add mod)
• Ensure not conflicting with Drag & Drop behaviors within the app (mod reordering, etc)

Technically the whole window does allow it, but some controls swallow it. I just haven't gone around to fixing it on a control by control basis.

I remember having some trouble getting the mod list to not swallow it.

I was hoping that each component could attempt to process, and if nothing handles the object type, then throw the Drag&Drop event to their parent. Each component would do this, with the final parent being MainWindow or App. This top level could handle or discard if nothing has processed it at this point.

I don't know how feasible it is, but something I'll look into.

That's what's supposed to happen, but unfortunately some controls swallow the event and don't let it bubble up to the window. I never got around to trying to fix it control bt control.

Tried a few solutions such as

                DragDrop.DragEnter="DragDrop_PassthroughHandler"
                DragDrop.DragLeave="DragDrop_PassthroughHandler"
                DragDrop.DragOver="DragDrop_PassthroughHandler"
                dd:DragDrop.IsDragSource="True"
                dd:DragDrop.IsDropTarget="True">

But ultimately even adding it on every component within AppSummaryPage either breaks the theming on the internal drag&drop mod sorting, or threw away the mod install event.

I recommend leaving this issue open if anyone else wants to take a crack at it and has more experience with drag&drop and WPF.
