All,
I have an app which stores the last viewed record in a plist file when it terminates. When the app launches again, I fetch the data for the last viewed record and fill my app’s form. All form fields barring a single column table view get populated with the data pertaining to the last viewed record when the App launches. I’m at my wits end because of this. In the plist file, I store Car names as records and their information. The Car Names are displayed in a combo box, which the user selects and the relevant info is displayed.
The surprising thing is that on launch aCarFeatureTable rows aren’t selected, but if I changes the combo box values, the rows get selected.
Here is my code:
property aCarFeatureTable: missing value -- The Single Column table
property aCarFeatureList :{"Feature1","Feature2","Feature3"}-- The feature list, displayed in the single column table
property theArrayController : missing value -- connected in Interface Builder
property theData : {} -- the table data
property aCarName : missing value
on applicationWillFinishLaunching_(aNotification)
tell current application's NSArray to set theArray to arrayWithArray_(aCarFeatureList)
-- set our property to sorted list
tell theArray to set my theData to sortedArrayUsingSelector_("localizedStandardCompare:")
-- Insert code here to initialize your application before any files are opened
end applicationWillFinishLaunching_
on awakeFromNib()
set plistFileString to (path to preferences as string) & "myCarData.plist"
set PLIST_PATH to POSIX path of plistFileString
try
set thePlistData to NSMutableDictionary's alloc()'s initWithContentsOfFile_(PLIST_PATH)
on error errMsg
aErrorMsg's setStringValue_(errMsg)
return
end try
my populate_Combobox() --populate the Combo Box
end awakeFromNib
on populate_Combobox()
set last_viewedcar to ""
set tempKeys to thePlistData's allKeys() --find all keys
set myList to {}
repeat with oneKey in tempKeys
try
if oneKey as string is not equal to "Last_Car" then
set end of myList to (oneKey as string)
end if
end try
end repeat
aCarName's removeAllItems() -- clear content of combo box
try --see what car was the last used when the app was run
set last_viewedCar to (thePlistData's valueForKey_("Last_Car")) as string
end try
if myList is not equal to {} then --if the list is not empty
repeat with oneList in myList --repopulate combo box
aCarName's addItemWithObjectValue_(oneList)
end repeat
aCarName's setStringValue_(last_viewedCar)
aCarName's selectItemWithObjectValue_(last_viewedCar)
my fillForm(last_viewedCar)
end if
end populate_Combobox
my fillForm(carVal)
-- Fetch data from plist file for the car value and populate the form fields:
set theDict to thePlistData's valueForKey_(carVal)
set rowStr to (theDict's valueForKey_("theCarFeatures")) as string
-- rowStr will contain values like "1,2,14" which are the row numbers corresponding to the features, the user selected
my selectRowIndexes(rowStr,aCarFeatureTable)
end fillForm
on selectRowIndexes(val,obj)
if val is equal to "" or val is equal to missing value or val is equal to "missing value" then
tell theArrayController to setSelectionIndex_(0) # Select row 0
else
set {myTID, AppleScript's text item delimiters} to {AppleScript's text item delimiters, {","}}
set selRowsList to text items of val
set AppleScript's text item delimiters to myTID -- It's considered good practice to return the TID's to their original state
set theSet to current application's NSMutableIndexSet's alloc()'s init()
repeat with i in selRowsList
theSet's addIndex_(i as integer)
end repeat
obj's selectRowIndexes_byExtendingSelection_(theSet, false)
end if
end selectRowIndexes
