GOP done right

Getting graph on parent patches to display correctly is a bit difficult to do on Pd (at least up to now, which is 0.38). Here's a step by step introduction on how to get beautiful results:

1. use a cnv object as a background,
2. Put all you want to see on top of the background cnv
3. remember its dimensions as x and y.
4. Set "Graph On Parent" to true.
5. resize the abstraction, so that only the bg-cnv plus about 15 pixel above it are visible. The empty space above is for the abstraction name.
6. save, close, File->New, put: your_gop_abs
7. Right-click your_gop_abs, edit Properties: Set width to: x (from above) + 2 pixels Set height to: y (from above) + 15 pixels. Save properties.
8. Right-click again and Open your your_gop_abs
9. SAVE it! Yes, again! This is important, as the resizing done in the parent patch in step 7) is not saved yet in the child abstraction.
10. you migtht need to fiddle a bit with the positions of graphical objects.

Doing GOP on Data Structures is a little bit different. GOP data always lives inside a subpatch (like pd paint). Lets assume we have some data inside a subpatch that looks like this:

Now you can set this to be graph on parent using the usual properties dialog:

However if you look in the main patch now, you will see, that the dimensions of the subpatch are totally messed up:

To change this, you need to edit the properties of the subpatch inside the main patch:

and set the x- and y-dimensions, so that they match the screen sizes:

Now the data structures inside the subpatches shines through the way you expect them to be.
