<SOLVED > Treeview select draged Item or set mime data from draged item

[anda_skoa]

Is this a good idea?
Won't that start a drag even when you are just clicking to select?

My understanding is that the startDrag() method is where you should be starting drag operations, since it not only takes care of the mouse event handling, it also respects the "drag distance", i.e. the minimum mouse move while the button is down to start a drag.

As a side note: that setUrls() call doesn't make much sense, you are not filling the list anywhere, right?

Also, you can just use model()->data() or tempindex.data() to get the filename, no need for casting.

I append the filename to it. Or is there a way to set just one Url directly?

urllist.append(QString("file:"+filename));

urllist.append(QString("file:"+filename));

To copy to clipboard, switch view to plain text mode 

How do you reimplement startDrag() ?

I tried it this way?

void customtreeview::startDrag()
{
 
}

void customtreeview::startDrag()
{
   
}

To copy to clipboard, switch view to plain text mode 

and put a qDebug in it, but it's never called.
Otherwise what you say make perfect sense, but out of ignorance I am still stuck with my workaround.

And model()->Data() just returns the filename without path. So it isn't much use to me either.

Right, sorry, missed that line.
Better use QUrl::fromLocalFile() instead of string concatentation though.

This is not the correct signature, you are missing the argument.

Ah, but you can also retrieve the path, QFileSystemModel::FilePathRole.
Anyway, casting should be fine, but you might want to check the result of the cast for null pointer.

The documentation sais:

void QAbstractItemView::startDrag(Qt::DropActions supportedActions) [virtual protected]
Starts a drag by calling drag->exec() using the given supportedActions.

void QAbstractItemView::startDrag(Qt::DropActions supportedActions) [virtual protected]
Starts a drag by calling drag->exec() using the given supportedActions.

To copy to clipboard, switch view to plain text mode 

If I use Qt:ropActions as an Argument I get the Error:

variable or field 'startDrag' declared void
void customtreeview::startDrag(Qt::IgnoreAction)

What now? Any link to an example perhaps?

Exactly!

If I use Qt:ropActions as an Argument I get the Error:

variable or field 'startDrag' declared void
void customtreeview::startDrag(Qt::IgnoreAction)

That looks wrong, almost like you had written exactly that instead of the actual method signature.
