Is there a known problem with QMimeData on Mac OS X?

Try upgrading your Qt installation (4.3.4 is the latest stable release).

Try upgrading your Qt installation (4.3.4 is the latest stable release).

The duples are gone. Now I see just one plain/text entry in the clipboard. This does not really solve my problem, since I would like to get the html-source similar to the other two platforms.

I do not know how the textedit application (distributed with Mac OSX) handles it, but this programm is able to receive the html-code from at least safari with the same sequence of <Apple>A/<Apple>C and <Apple>V in the textedit window. It looks a little bit like garbage, but it contains links (and this is what I would like to get).

On my mac i use.....

qmake -v
QMake version 2.01a
Using Qt version 4.4.0-snapshot-20070608 in /usr/local/Trolltech/Qt-4.4.0-snapshot-20070608/lib

and its run OK

try to build

only append text plain ...

To copy to clipboard, switch view to plain text mode

Patrick, how is the code you pasted related to the problem? The guy just said his QMimeData doesn't contain "text/html", so why the hell do you paste code which runs some tidy clone on html code? How is that relevant?

[Wurgl]

How is that relevant?

It helps me a little bit. I see now, that the Clipboard on OSX can hold text/plain and text/html at the same time and that Qt/Mac (even Qt 4.2.1) and my code work as expected. So it seems that I have to ask at the project pages of the relevant browsers.

Have you seen the "dropsite" example (or demo) bundled with Qt? It's useful for testing mime-types of dragged objects and dragging and pasting from clipboard is using the same technique (you can probably even modify the example to react on pasting as well). And you can see what mime-types are created when you drag data from these applications.
