Re: Multple windows within the same process
Pat,
To expand a little on the other comments for you to be able to _keep_
windows open when you use the * they must be opened from an existing
window. Otherwise they pop open and then close again. Another difference is
when you call
DIALOG("myForm";*)
the method doesn't stop with DIALOG. It keep going. So you don't want to
use this for something where you want to wait for the user input.
This suggests a toolbar sort of approach to the UI where you open a window
that is intended to remain open. Or that these subsidiary windows be
thematically linked to the main window. For instance, I have a database
that allows 3 different windows to call a parser for importing data.
The parser opens in the process shared by those 3 windows. When you close
the root window, or otherwise end the process, all windows open in that
process close as well.
The suggestion I've picked up is to look at defining a single process as
the UI process and opening most, or all, the windows users interact with in
that process. In this context a process variable becomes like an IP var has
been - available to all the windows. But with CALL FORM you don't even need
to think about it that way.
Where workers come in is to do, well - work. All the heavy processing be it
lookups, calculations, whatever can be done by workers and just the results
are pass back to the form that initiated them. It's a really different way
of thinking about building your forms.

Re: Multple windows within the same process
Pat: The asterisk was added to the Dialog command in V12. That was all well and good but the developer had to get creative to communicate with a given window within a process because Call process was picked up by the frontmost window in a process. The “Call form” command (late V15) allows us to run code in the context of a given window making it very easy to update specific windows, regardless of how they were opened. If you’re working in a multi window environment, it’s easy to do “real time updates” by messaging processes so that they can refresh the data that they’re displaying. -- Douglas von Roeder 949-910-4084 On Wed, Apr 29, 2020 at 4:19 PM Chuck Miller via 4D_Tech < 4d_tech@lists.4d.com> wrote: > workers > > > > Chuck Miller Voice: (617) 739-0306 > Informed Solutions, Inc.

Multple windows within the same process
Maybe it was in a dream ... but I'm sure I recall reading something about a new feature (v17) that allows more than one window to be open within a process. But now I can't find that info.
