Hi,

I'm searching for a message, which can be send to an array, to change it's appearance from bezier curve to bar graph and vice versa.
Does such message exist?

And in general:
Is it possible to find out, which messages are exepted by an object? I've been looking through the source code of pd, but couldn't find the right part.

Thank for help,
Xaver

@xgr Yes, it is hidden away somewhere, like so much good stuff. I think there are some changes between Extended and Vanilla, but what you are looking for remains the same.
[;
array1 arraydialog array1 100 $1 0(

where array1 is the array name, 100 is the size, and $1 is:
•0 = points, don't save contents
•1 = points, save contents
•2 = polygon, don't save contents
•3 = polygon, save.contents
•4 = curve, don't save contents
•5 = curve, save contents

So........... array_dial.pd

Thanks a lot,

In Purr Data arraydialog needs 8 arguments. For example this would work:
[; array1 arraydialog array1 100 $1 0 5 5 5 5 (

Does anybody know what the 4 extra arguments are used for?

Here is the source code, but I couldn't figure it out:
https://git.purrdata.net/jwilkes/purr-data/blob/master/pd/src/g_array.c
lines 595 - 791

@xgr Looks like......
0 Arrayname (symbol)
1 arraysize (float)
2 as above
3 other?..... maybe 0= "do not open property dialog box"? 1="do"?
4 Unknown, unused...?
5 Unknown, unused...?
6 Fill colour (symbol)
7 Outline Colour (symbol)

But I could be very wrong.
@jancsika might chip in and reveal all.
Does this do anything? array_dial2.pd (I don't have Purr)
David.

Your patch works. It changes the fill color to blue and the outline color to orange. The fill color is used with setting the view of the array to bar graph, which is an extra option in Purr Data. To get this extra option your radio button needs 8 buttons instead of 6.

By the way: I didn't know colors can be changed by name. Is there an overview which names might be used?

@xgr Probably the tcl color names.......... http://wiki.tcl.tk/37701
Remove any spaces in the names to make them work...... change "dark orange" to "darkorange"
Here is some more "stuff"...... stuff.zip

Replying to your original question (part2)....... You can find some info (not always complete) here... https://puredata.info/docs/developer/PdFileFormat
Usually you need to give your gui a receive name and send it a message. Not everything works.
