Hi all,
I was thinking about developing a drag and drop application and was curious
how difficult it is to do. Basically I want to have a set of objects that I
move around the screen and drop into place.
Anyone else ever done it? Got any tips?
Thanks,

- Cameron -LOTS of applications--several I've written, I know--do this sort of thing. You'll need to learn about bind(), and most likely the events <1> <B1-Motion> <ButtonReleas e-1> in particular: you'll teach <1> to start a drag, <B1-Motion> to display the dragged object moving around the screen, and <ButtonReleas e-1> to finish the drop.
Have you read <URL: http:// groups.google. com/groups?as_q=dra g+drop+tkinter& as_ugroup=comp. lang.python >?
I should add that drag and drop in the same application can be done
easily, but it's hard to do it between your application and others (too
much window manager dependencies... )

Excellent. Thanks for the head start.
A couple of questions.
1) If I want to have a moving object, and not just a cursor that
represents the moving object, do I need to continually pack and unpack
the widget that holds the object and redraw it to give it the
appearance of moving? I know sometimes the redrawing can cause
applications to flicker too much, destroying the effect. I don't know
if there's an optimum way to do this.
2) Also, in reading I found an old module called Tkdnd (drag and
drop). It was an experimental module that was supposed to be updated
but never was. Now I can't find any more information on it. Does this
module still exist or work?
Thanks,

Hi,
I am having problems using drag drop and re-ordering items.
Example:
When I drag and item from position 1 and drag it to position 3, I want
to re-order all the items accordingly. This means an item in position
1 is now is position 3 and item 2 is now in postion 1 and item 3 is in
position 2 and position 4 and 5 stay the same.
I have searched the web.

Is it always OLE?

Hi all i`m having a small problem with windows forms, i`m attempting to
provide the following functionality to a form.
Ability to drag and drop another form onto a form and then to dock this
form...
Quite a mouthful however a good example of this is within the VS.NET 6 IDE.
Grab your solution explorer panel and drop it outside of the IDE, then
drag/drop it back in and watch it dock.

I have a VS.NET windows application which use drag-drop feather. It works
fine when application start, but stops working after application run one or
two days. The application is related to Video process, CPU/Memory extensive.
The drag-drop is in a new windows form. It drags from TreeView Control to
other control in the same form. It cannot trigger ItemDrag event of TreeView
after drag-drop feather die.
Can you give me any idea? Thanks.

I'm loading a text file to a RichTextBox control to drag a selection of a
text and drop it into a tree view control. It works except after the drag
and drop operation the RichTextBox scrolls to the top. This is very
inconvenient because after the drag-drop operation the user has to scroll
down to where he was before. Is there anyway to make the RichTextBox stop
jumping to the top after a drag-drop from it?

Hello,
I am trying to drag and drop a label control from one cell in a
tablelayoutpanel to another (VB2005). There is no problem if both
cells are visible, but i cannot get the tablelayoutpanel to scroll in
any direction (autoscroll is on), when the cell i want to drag to is
no currently visible and requires scrolling to get to see it.
Any suggestions would be greatly appreciated.

Hi all,
I have a treeview that has drag drop.
Works well enough but...
If you drag out of bounds of the treeview the nodrop icon comes on.
Fair enough.
But when I move back inside the treeview the nodrop icon stays on and
essentially the action is cancelled when I release the mouse.
I would like to somehow 'retrieve' the drag action when the mouse
moves back inside the treeview to a legitimate drop point.
Any thoughts on how to do this...

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
