[survey] All object properties programatically available?

email me off list with Yea or nay
I propose 2 commands : Set Object Property({*;}Object/variable;property;value) object/variable is an object (with the appropriate leading asterisk), or a variable reference. Property - is a string/text which is the property name (as appears in the property list). Value - is a string/text of the value you want to set the property to. ex: Set Object Property(my_Listbox_column;"Sortable";"False") second Get Object Property({*;}Obejct/variable;property) -> value object/variable is an object (with the appropriate leading asterisk), or a variable reference. Property - is a string/text which is the property name (as appears in the property list). Value - is a string/text of the current value of the property. ex: $Current_Setting:=Get Object Property(my_Listbox_Column;"Expression") `returns the data source Why: - there are MANY properties that can not be accessed via code. - a Generic/general property accesor like the above will stop the proliferation of SET THIS, and GET THAT; alternatively the language will get (has already gotten?) too over burdened with SET THIS, and GET THAT commands. - We as developers really **NEED** access to a lot of these properties, programatically. Especially as 4D moves to allowing us to do more and more things dynamically (like listboxes). ********************************************************************** Get the speed and power of 4D v11 SQL before upgrade prices increase - http://www.4d.com 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4D.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4D_Tech-Unsubscribe@... ********************************************************************** |

Actually - yes and no
I specifically asked about this at the closing session. Not an exact quote but a close approximation : There will be setters and getters for all *existing* setters and getters New ones will eventually be added. However, as I recall, there was no specific time frame for the exposing of **ALL** object properties, of all objects. I would like, given enough feed back from this thread, to put together a proposal for 4D including ideas about useful functionality - such as being able to get all object properties (for a specific object) into an array. get all object properties({*;}Object/variable; arrtxt_Property_Names;arrtxt_Property_Type) where all properties and their types are placed into the arrays. My hope is that this concept can be pushed up the priority list a bit, maybe enough for v12. Probably hoping for too much... but what the hell.. :) On Thu, 29 Oct 2009 00:16:43 +0100, Ortwin Zillgen wrote: > that' scheduled for V12: Getters and Setters > <http://www.4d.com/blog/summit-keynote-highlights-part-one.html> > > very helpful indeed > > > > Regards > Ortwin Zillgen > ___________________________________________________ > Stadt Land Fluß * Geographic Informationsystems > <mailto:info@...> <http://dddd.mettre.de?4713> > RSS <feed://dddd.mettre.de/dddd.xml> > RSS <feed://dddd.mettre.de/f/DDDD_Links.xml> > > > > ********************************************************************** > Get the speed and power of 4D v11 SQL > before upgrade prices increase - http://www.4d.com > > 4D Internet Users Group (4D iNUG) > FAQ: http://lists.4d.com/faqnug.html > Archive: http://lists.4D.com/archives.html > Options: https://lists.4d.com/mailman/options/4d_tech > Unsub: mailto:4D_Tech-Unsubscribe@... > ********************************************************************** > Get the speed and power of 4D v11 SQL before upgrade prices increase - http://www.4d.com 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4D.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4D_Tech-Unsubscribe@... ********************************************************************** |

Hi Chip,
Yes. A Visual Studio approach where everything is possible in code, even designing forms would be ideal. I would not actually design in code but just the ability to tweak the code is very powerful way to fine tune sometimes. -- David Weinberg Lead 4D Developer Kaplan IT Services Direct Line: 020 7939 9851 2009/10/28 Chip Scheide <4d_Only@...> > email me off list with Yea or nay > > I propose 2 commands : > > Set Object Property({*;}Object/variable;property;value) > object/variable is an object (with the appropriate leading asterisk), > or a variable reference. > Property - is a string/text which is the property name (as appears in > the property list). > Value - is a string/text of the value you want to set the property to. > > ex: > Set Object Property(my_Listbox_column;"Sortable";"False") > > second > Get Object Property({*;}Obejct/variable;property) -> value > object/variable is an object (with the appropriate leading asterisk), > or a variable reference. > Property - is a string/text which is the property name (as appears in > the property list). > Value - is a string/text of the current value of the property. > > ex: > $Current_Setting:=Get Object Property(my_Listbox_Column;"Expression") > `returns the data source > > > Why: > - there are MANY properties that can not be accessed via code. > - a Generic/general property accesor like the above will stop the > proliferation of SET THIS, and GET THAT; alternatively > the language will get (has already gotten?) too over burdened with SET > THIS, and GET THAT commands. > - We as developers really **NEED** access to a lot of these properties, > programatically.
