Actually you can. The problem is that an "object" can be a single item such as a graphic object or a field or it can be a group of objects grouped together.
When you try to access object specific properties in the inspector such as its name or its "hide object when" setting for a grouped object, you can only access this info for the group, not for any one item that makes up that group.
When you use button setup to turn a layout object into a button, FileMaker groups the selected layout object (or objects) with an invisible "button object". You now can only access the object name and "hide object when" boxes in the Inspector for this newly created group.
So the way to fix this is to ungroup the button. That destroys the invisible button object, however, so you have to remember what you had selected for that button in button set up so that you can recreate that option in button set up after modifying the "hide object when" property for the object in question.
One way to avoid this little snarl is to remove the Hide object when setting, use button set up to turn it into a button and then add the hide object when setting to the button plus visible object group thus created. (Sometimes I duplicate a button, then ungroup and modify the parts of the original button before setting it back up as a button--referring to the copy of the button to make sure that I set it back up correctly.)
Yeah, I figured it was grouping some sort of invisible button object. I did go ahead and add the hide object after creating the button. However, it seems like if there is only one object in the button, FileMaker could copy over the attribute to the button "group".
What I'd like to be able to do is to have a way to access and modify "object specific properties" of individual items of a grouped object without having to ungroup them.
I agree, that would be fantastic. Need some way to drill down into the group hierarchy.
Time to make that a feature request then: http://www.filemaker.com/company/contact/feature_request.html
Posts by TSGal have indicated that clearly stating the reason WHY the desired feature is important can make or break it's consideration by FileMaker Inc staff when evaluating the feature request.
This behaviour is surely annoying. I have made a feature request as well, lets see if anything happens.
I also think that must be considered a bug for buttons with only the one object. The attributes should be copied to the button object.
For multi-object buttons with individual parameters, the current behaviour is somewhat expected, although it should say "Multiple values" as it currently says when you select a groups of objects.
It is interesting that tooltips work in the expected way, but not Hide Object or Name (and maybe other parameters).
I agree with Andreas!
I've submitted a feature request. Thanks Phil.
