#X text 212 124 Because of the two inlets and the one outlet \, the containing box (in the parent patch) has two inlets and one outlet. They respect the left-to-right order of the inlet and outlet objects in the subpatch., f 52;
#X text 212 28 This is a sample subpatch which maintains the sum of two inputs \, doing the computation when either input changes. If it's the left input \, the [+] object takes care if it. If the right \, the [trigger] object first gives the [+] the new value \, then "bangs" the right inlet to make [+] do the computation., f 52;
#X text 97 213 Aside: this shows why \, in Pd and Max \, objects such as [+] only trigger on their left inlets: it's easy to build up from there \, but if more than one inlet were "hot" \, you wouldn't be able to change both of them without firing the calculation twice., f 63;

#X text 503 348 Note that "\$1" \, etc \, has a different meaning in object boxes. Open one of the "sendnumber" abstractions for details., f 45;
#X text 503 246 If you change one copy of an abstraction the change isn't automatically made on any other copies. You must keep track \, save the changes \, and cause Pd to reload the other copies (for example \, by closing and reopening the containing patch.), f 45;

#X text 503 116 There is a separate file in this directory named "sendnumber.pd" which is loaded every time you type "sendnumber" in a box. Click on a "sendnumber" box above to see it. You can make changes in the subpatch and save them. The changes will be saved back to sendnumber.pd and not as part of this (containing) patch., f 45;

#X text 51 23 You can nest entire windows inside Pd boxes (and so on \, as deep as you wish.) There are two different ways to do it. First \, if you just want to add a room to the house \, so to speak \, type "pd" into an object box. If you click on the box (in run mode) the subwindow appears., f 56;
#X text 54 470 There is also a facility for making many copies of a patch which track any changes you make in the original. This subpatch type is called an abstraction. For example \, here's a simple abstraction that sends a number to a "receive" on command:, f 57;

This way you can click and interact with GUI objects. Right click on the subpatch below to the right and choose "open" to check it out. You can turn a regular subpatch into a "Graph on Parent" one by accessing the properties on right click.;
#X text 503 408 Abstractions can also "Graph on Parent" \, as the one below. This example below also makes use of a feature in the [pdcontrol] object to load arguments. Open it to check it out., f 45;
