Delphi versions: 5, 6, 7, 2005, and 2006.
The usage is quite simple: place a TDropFilesTarget on your form, link
the "TargetControl" property to your control (i.e. TListBox) and write
an event handler. The event get's fired when files are dropped on that
control and the passed TDropFilesInfo object holds all the information.
To install the component into your Delphi palette, just create a new
or open an existing package and add DropFilesTarget.pas to it. The
accompanying DropFilesTarget.dcr will be added automatically.
Also take a look at the included sample application, a few lines of code
often say more than 1,000 words ;) It can be compiled without installing
the component! |
