Hey all,

I am starting my journey into dynamic patching and was wondering if it is possible to dynamically create sliders, toggles, etc within the current .pd file. I have found a lot of examples for creating objects within subpatches, but not directly in the current one.

The reason I want to do this is I am designing some tools for iPad, which PDParty cannot render graph on parent objects, so all GUI objects need to reside in the main file.

@DespairBear You can use [namecanvas] and then send your messages to what ever you named the canvas, but you can not send [clear( unless you want to cause a crash and deleting objects is a pain. If you can use externals than iemguts would be a good idea, it makes dynamic patching much easier all around.

@DespairBear Yes.... this is the message format.....

But removing them is a little more complex.... you have to use [find( [findagain( and [cut( messages.

@whale-av Awesome, are those messages documented anywhere? I'm still learning my way around this side of PD. Is there a good way to tell what arguments the internal messages take? Trying to figure out how [find] works. I'm assuming it takes a symbol

Also, is it possible to create a canvas in a similar manner to other GUI elements? I tried using the reference here https://puredata.info/docs/developer/PdFileFormat#r21

but am receiving the error
canvas: no method for 'canvas'
with this message

Thanks in advance. Really appreciate the help

@DespairBear canvas is patch data, not the canvas object which is cnv. https://puredata.info/docs/developer/PdFileFormat#r369
Simple trick to find out the message for an object, create the object you want in a blank file, set any properties and then save the patch and open it in a text editor.

@oid Ahhh okay that makes sense. Thanks for clarifying the difference within the save file. I had just searched the file for "canvas" and went with that haha
