Hello everyone,
I would like to know how to open a Window in VisualWorks and make it modal? Any suggestions? thanks, David _______________________________________________ vwnc mailing list [hidden email] http://lists.cs.uiuc.edu/mailman/listinfo/vwnc |

Hi David,
just make your application model a subclass of SimpleDialog. Add an accept and cancel button to it and you should be done. When you open it, you'll have a modal dialog. Kind regards Karsten

When you open it, you'll have a modal dialog. This is not always desirable. I for one would need to open any ApplicationModel with modal status when needed. It is something I never really figured out how to do. If anyone knows, please share your wisdom. Nowadays modal interaction should be embedded into the main application window anyway. The single-window design is increasingly getting popular for a reason.

At its most general, you can open your normal ApplicationModel as a
dialog like this: MyAppModel class>>openAsDialog | appModel | appModel := self new. appModel openDialogInterface: #windowSpec. MyAppModel>>openDialogInterface: aSymbol | theDialog result | theDialog := SimpleDialog new. theDialog preBuildBlock: [:sd :bldr | self builder: bldr. self preBuildWith: bldr]; postBuildBlock: [:sd :bldr | self postBuildWith: bldr]; postOpenBlock: [:sd :bldr | self postOpenWith: bldr]. result := theDialog openFor: self interface: aSymbol. self noticeOfWindowClose: self builder window. ^result Steve > -----Original Message----- > From: [hidden email] [mailto:[hidden email]] On > Behalf Of andre > Sent: 27. syyskuuta 2012 15:06 > To: Karsten Kusche > Cc: [hidden email]; [hidden email] > Subject: Re: [vwnc] modal windows in VW > > > On 27.09.2012, at 09:13, Karsten Kusche wrote: > > > just make your application model a subclass of SimpleDialog. > > Add an accept and cancel button to it and you should be done.

I would like to make a dialog window modal to a parent window only and not block other windows from user interactions.
Thanks, Aik-Siong Koh |

I decided to look into the doc VW7.9 GUIDevGuide.pdf to see what it has to say about modal windows. Apparently, since 7.1, modal windows specific to an application were implemented in VW.
Page 3-6 says: Prior to 7.1, each window stored a queue of events sent to it, and processing of events was directed by a single instance of ControlManager, named ScheduledControllers. Accordingly, there was only a single UI process, the one run by ScheduledControllers. To allow for multiple UI processes, this mechanism was changed in 7.1. Each window now has a WindowManager that holds an event queue, representing a single UI process. Each WindowManager can manage the events for one or more windows. Usually, only closely related windows, such as windows in master/slave relation, or windows and dialogs they raise, share a manager. Note that a dialog blocks only the those windows sharing its window manager. |

This is not quite accurate. It is correct for the smalltalk code but not the
VM. We have been waiting for over 10 years for the VM to get updated. Terry =========================================================== Terry Raymond Crafted Smalltalk 80 Lazywood Ln.

Terry, I know there are some ARs with keywords that you mention below.
So that I can sort out whether I'm thinking about the same problem, can you elaborate on what is the inaccuracy and the bits that you see missing in the VM?

I don't think it's accurate even for the Smalltalk code, since there's only a single global #modalWindowChain, rather than one per WindowManager (or possibly one per set of WindowManagers, which might well be what would actually be wanted).
In any case, I think the modern way to handle the case for which the multiple modalWindowChain part of MultiProcUI was envisaged would be to use multiple VW instances, since that also allows each to have its own core.

The original intent was for one dialog chain per window manager. However,
when I discovered that the VM would not support multiple dialog chains, as I recall it is something to do with the message queue for windows, I had to go with the global chain. The multiprocUI was intended to allow multiple applications to act independently within one image.

Thanks for the feedback. So VW cannot have a window modal to a parent window only. It must be modal to the entire image. Right?
How can I create a window that is modal to a parent only? Is it possible? Any advice would be appreciated. Thanks, Aik-Siong Koh |

Well, it seems to me that if you:
-- make the window a "slave" to the parent (see the doc for master/slave setup) -- while the slave is open, simply ignore all events headed to the master window (at the controller) You could get what you want On Apr 17, 2013, at 10:21 PM, askoh wrote: > Thanks for the feedback.
