set theValue to theObject's valueForKey_(".title")
yields this in console:
2009-09-24 11:28:33.319 backupC[1154:a0f] *** -[backupCAppDelegate testclick:]: [<Backupset 0x20009db80> valueForUndefinedKey:]: this class is not key value coding-compliant for the key properties.title. (error -10000)
The key is defined in the array controller key list as well as the properties instance of NSMutableDictionary.
I wonder if we are accessing the Dictionary object or something else with
set theObject to mySelectedObject's objectAtIndex_(0)
No, I saw that just after the last post and removed it.
Still no luck.
I tried “properties.title” as well and that didn’t work.
It’s perplexing because I can get a count with selectedObjects or arrangedObjects so there is definitely and array or dictionary there representing the table contents but why it doesn’t have a key “title”. I wonder if I can get it to somehow log the dictionary itself so I can see what is in there.
on testclick_(sender)
set mySelectedObject to Backset's selectedObjects()
--set mySelectedObject to Backset's arrangedObjects()
--we can get a count at least
--display dialog (count of mySelectedObject)
set theObject to mySelectedObject's objectAtIndex_(0)
set theValue to theObject's |properties|'s valueForKey_("title")
-- no key "title" it says
display dialog "" & theValue & ""
end testclick_
The line that correctly identifies the object is:
set theValue to theObject's |properties|'s valueForKey_("title")
The selected object in Backset is an object created from the Backupset class. Once you get hold of
the object, you ask its array “properties” for its valueForKey.
I kept trying “properties” and it just didn’t look right because it was an applescript word and didn’t belong to the object it was directed at. I forgot the pipes around it!
I suspect you’re making things harder for yourself than necessary.
You can use an Array Controller without any code at all. You have your main script containing a variable that you bind the Array Controller to, and then you bind the table to the Array Controller. You also bind another variable to the selection of the Array Controller. No code needed, and your variables change as the table changes.
This sounds right - though I have two tables, each with it’s own array controller. Table 2’s contents are bound to table 1’s selection and I also have a bunch of user preferences that are bound to table 1’s selection. So changing selection in table 1 changes the list in the other table and also the prefs values in the app.
I can’t bind the prefs values, for example, to my script variables because they are already bound to the Array Controller for table 1. And I have to “get” the values of the list items in table 2 by the lines indicated earlier
This is all set up with minimal code using several class files and the controllers. But"getting" and “setting” are a pain.
So I hope there is a simpler way because now I am trying to manually “set” the values for a new row in table 2 via the + button with this example which fails so far:
on addFilesToListTable_(sender)
set theKeys to NSArray's arrayWithObjects_("address", "subject")
set theVals to NSArray's arrayWithObjects_("someaddress", "somesubject")
set newDictinaryObject to NSMutableDictionary's alloc()'s initWithObjects_forKeys_(theVals, theKeys)
Sourcef's addObject_(newDictinaryObject)
end addFilesToListTable_
It does enter a new row but it is blank. I tried adding the required “nil” to the end of the lists, putting them in brackets etc. but no luck.
The bindings work great but accessing the tables is tricky without those nice bound variables in the script.
Take the code out of table 1’s Array Controller. Put a property in your AS called tableData, and bind table 1’s Array Controller to it. In your applicationWillFinishLaunching_ handler set tableData to a list of records:
set my tableData to {{firstName:“John”,lastName:“Smith”},…}
Now when you want to change the contents of table 1, you just change the value of my tableData (and not by using “set end of… to…”). So:
set my tableData to {{firstName:“Jane”,lastName:“Doe”}} & tableData
You won’t be able to bind to prefs as well, but scripting prefs is is easier than scripting table contents.
I’ll mess around with this. A simple record would be far nicer to use than the array language. . The values I need to change are in table 2 though and that is the one bound to table 1’s selection. It seems a bit trickier - because I can’t unbind table 2 to make it available to script.
And the prefs (all 24 of them!) could be done with selectionChanged but that means they need their own array somehow linked to the table’s array (scary.)
which I have seen in many places as the usual way for this kind of binding of tables…
Now - I could go back to the old way using glue code for the two tables with datasource outlets and then have tables available for binding but that involves way more code and all the datasource handlers etc…
But I really would like to find a simpler way. in the end if I can get access to set the table values right, it still may be less code for me in the ned. Maybe if you post your example - and if you can do it with two tables linked my way, let me know. I’m no expert here!
Have a property in your AppDelegate called theData, and set it to a list of records like:
set my theData to {{mailBox:"Inbox", emails:{{firstName:"Ray", lastName:"Robertson"}, {firstName:"Shane", lastName:"Stanley"}}}, {mailBox:"Outbox", emails:{{firstName:"Jane", lastName:"Smith"}, {firstName:"Paula", lastName:"Ramsay"}}}}
Now add an Array Controller, call it First, and bind its Content Array to the AppDelegate, with Model Key Path of theData.
In your first table, bind the first column’s Value to First, arrangedObjects, MKP mailBox.
Now add a second Array Controller, call it Second, and bind its Content Array to First, Controller Key selection, MKP emails.
Finally, bind the Value of the first column of your second table to Second, arrangedObjects, MKP firstName. Bind the second similarly to lastName.
Now you can use the remove: method of the controllers, and you can add by modifying theData.
A tip for bindings stuff: do one at a time and test after each; it makes trouble-shooting so much easier.
I gave it a try. I got the first table working Ok though if you edit rows they won’t retain the new values when you remove an item from the row.
Adding table 2 works also but is more buggy. When adding a row the first table gets deselected and you don’t see the new row. Same issue with editing rows and sometimes the rows get added instead of removed!
to get the table 1 to select the correct row after adding rows to table two.
If it can work in a non buggy way it will be good. I still prefer using the classes I have set up for handling the array controllers since it is very solid and requires no workarounds.
Yet if this can work, it will be a nice simple solution, especially for those with no OBJ-C in their proj.
property theData:missing value
on addSet_(sender)
set my theData to my theData & {{backupset:"newBackupset", sourcefiles:{{fileicon:"",sourcefile:"somefile", filesize:"---"}}}}
end addSet_
on awakeFromNib()
set my theData to {{backupset:"newBackupset", sourcefiles:{{fileicon:"a", sourcefile:"somefile", filesize:"---"}}}, {backupset:"newBackupset", sourcefiles:{{fileicon:"b", sourcefile:"anothersomefile", filesize:"---"}}}}
end awakeFromNib
for the add and the built in “remove” connected through IB.
I started fresh again and copied exactly all the same settings you had in the sample and went back to just one table and it does the same thing: When you edit rows and then do “remove”, the rows return to their original values. It seems better than before otherwsie. Worse trouble begins when I hook up the second table.
