#X text 92 231 To solve this problem \, the abstraction below uses
[initbang] instead of [loadbang]. [initbang] will send a bang before
Pd initializes the parent patch \, so that the [outlet] is created
before the connection between objects is made. Thus \, you can see
below that the objects are connected successfully.;
#X text 112 118 The above outlet is supposed to be connected to [print]
object below but [loadbang] sends its bang too late. Pd will try to
connect the abstraction's outlet to the inlet of [print] \, but this
will happen before [loadbang] is executed (i.e. \, before the outlet
exists). The result is the an error in the Pd window \, and connection
fails.;
#X text 92 372 Careful \, [initbang] sends its bang when the patch
is starting to load \, so things like GUI objects will not have created
their visual elements yet.;

#X text 160 460 - a bang message is sent when the containing parent
patch first opens the abstraction as an embedded object. If the patch
is a top-most patch \, no bang will ever be sent.;
#X text 93 51 The abstraction below dynamically creates an outlet using
[loadbang]. The [loadbang] object sends a bang after this help patch
has loaded.;
