Dear all,

I would like to drag an drop multiple lines in a tree view / list store. DnD works perfectly with single lines.
So does te selection of multiple lines.

But whenever I try to drag a complete selection of multiple lines to another place in the list, just one of the lines is moved.

Example:
My list store has 50 lines, enumerated from 1 to 50. I select lines 5-7. I drag those lines and drop them after line 30. As a result, I would like to have a sucession of lines like ...29-30-5-6-7-31-32.... But instead, only line 7 is moved, and the sucession is ...29-30-7-31-32....

Is the tree view / list store construction not capable of treatind dnd with multiple lines, or am I doing something wrong ?

Any help ist appreciated !

Hi,

I have never tried doing multiple DND of lines in a treeview, but if you are using the convenience function gtk_tree_view_set_reorderable () you will not have very much control over what is done. And most likely will only be able to move one row at a time.

If you want to move more rows at a time, you will probably need to add to the DND interface to allow that to happen.

... thank you for replying.

I just thought there could be some kind of "permit multiple" toggle, like that one for selections.

Will try to create my own DnD interface implementation instead ...
