Bug 89451

Version:            (using KDE KDE 3.2.1KDE 1.2)
Installed from:    0Mandrake RPMs

I'm having trouble with dragging files from KDE applications to a program I maintain (Mini vMac, at "http://www.gryphel.com/c/minivmac/"). It works fine with every non KDE application supporting drag and drop that I've tried. The X version of Mini vMac directly uses Xlib, and tries to support drag and drop by implementing the specification at "http://www.newplanetsoftware.com/xdnd/", which is supposed to be supported by KDE, according to "http://developer.kde.org/documentation/library/kdeqt/kde3arch/protocols-dnd.html".

I've prepared a small program to illustrate the problem, "dragtest", at: "http://www.gryphel.com/c/download/dragtest-0.1.0.src.tgz". To use it, extract, cd to the extracted dragtest directory, 'make', and then run with './dragtest'. It opens a "Drag Test" window, for receiving drag and drops, and writes debugging info to standard output. Usually it will report receiving XdndEnter, XdndPosition, XdndLeave, XdndDrop events. But when dragging from KDE applications it never receives XdndEnter and XdndPosition events, though it will receive XdndLeave events, and sometimes XdndDrop events (but only if you drag quickly enough to the DragTest window that it never notices the region between where drops aren't allowed). As far as I know just setting the XdndAware property ought to be enough to receive XdndEnter events. But it seems KDE is expecting something else.

Sorry if this is an already fixed bug. I downloaded the most recent distributions as of a few months ago, but I don't have access to broadband right now to keep up to date. Actually for my purposes I'm less interested in a fix for a future version of KDE, than I would be for a work around for old versions.

Here are some details of what I've tested. All tests were done in Virtual PC, running in Windows XP on an emachines T3065.
