Is it possible to drag and drop a web browser URL into a Lazarus app?
Are there some controls with that facility?
In fpGUI is is handled just like any other DND action. Simply register
what mime-type the drop target must look out for. It will then happile
accept a drop action if such a mime-type is supplied. Simple and easy
to use, and works on all platforms.
Lazarus's drag-n-drop is based on the very limited Delphi / Windows
DND, so is mainly build for in-app drag-n-drop, and not able to accept
external drag-n-drop actions. Normally (in Delphi) you would have to
revert to Windows API calls to get better DND support. I remember
seeing them (the Lazarus team) extending the default limited DND a bit
to support dropping files on a LCL app, but that is a far cry from
complete DND support.
Inter-process D&D requires special assistance by the OS. IMO such
operations are limited to drop file names, or other pure text, unless a
platform offers something like OLE-DragDrop.
