How to get multiple selected rows of table

Scripting Forums AppleScriptObjC and Xcode
#1

I’m trying to get multiple selected rows of my table. Using an Array, but even if I select more than one row, all I get back is the last selected… this is the code I use:

set vSelectedRows to plugstable's selectedRow() as integer

already tried with selectedRows but can’t get it to work…
Anyone a solution?!?
Thanks!

Try selectedRowIndexes()

#3

Works like a charm…
Thanks Shane!

#4

hmmm. This returns
[number of indexes: 6 (in 1 ranges), indexes: (1-6)]

Can’t get a repeat like this to work:

set vSelectedRows to plugstable's selectedRowIndexes()
		set vArrangedDS to arrangedObjects of theDParray
		repeat with vRow in vSelectedRows
			set vRow2Move to vArrangedDS's objectAtIndex_(vRow)
			set vPlugName to (vRow2Move's valueForKey_("plugname"))
			log vPlugName
		end repeat

it errors this:
<NSAppleEventDescriptor: 'obj '{ ‘form’:‘indx’, ‘want’:‘cobj’, ‘seld’:1, ‘from’:'obj '{ ‘form’:'ID ', ‘want’:‘ocid’, ‘seld’:‘kptr’($C0A90F0002000000$), ‘from’:‘null’() } }>

Try:

       repeat with vRow in (vSelectedRows as list)
#6

Doesn’t work…

set vSelectedRows to plugstable's selectedRowIndexes()
		set vArrangedDS to arrangedObjects of theDParray
		log vSelectedRows
		repeat with vRow in (vSelectedRows as list)
			log vRow
			--set vRow2Move to vArrangedDS's objectAtIndex_(vRow)
			--set vPlugStatus to (vRow's valueForKey_("plugswitch")) as boolean
			--set vPlugName to (vRow2Move's valueForKey_("plugname"))
			--log vPlugName
		end repeat

vRow logs exactly the same as vSelectedRows… bummer :frowning:

#7 
vRow logs exactly the same as vSelectedRows

Which is…?

#8

ohw sorry, this is in the log:

2010-04-15 19:58:39.788 PT Plug-in Manager[1499:a0f] <NSIndexSet: 0x200260000>[number of indexes: 5 (in 1 ranges), indexes: (2-6)]
2010-04-15 19:58:39.790 PT Plug-in Manager[1499:a0f] <NSIndexSet: 0x200260000>[number of indexes: 5 (in 1 ranges), indexes: (2-6)]

So it look likes some sort of c code and I’m afraid I’ll need some other c-code to get the indexes…

#9

Ah, so vSelectedRows is an NSSet, not an NSArray. So to convert it, you’ll need something like:

setRow list to (vSelectedRows's allObjects()) as list
#10

NSIndexSet != NSSet :wink:

#11

You’re right, of course :frowning:

So let’s forget about indexes, and ask the array controller for selectedObjects()…

#12

Aha, that was the trick!

Still confusing al this objective-c… Can’t get used to it after years of applescript studio…
Thank you very much Shane!

#13

Unlike AppleScript (Matt Neuburg calls it the “English-likeness” Monster), Objective-C is a real (programming) language. Personally it took 2 weeks to understand the basics of AppleScript and half a year to understand the basics of ObjC.

#14

Well, this works…:

set vSelectedRows to plugstable's selectedRowIndexes()
		set vArrangedDS to arrangedObjects of theDParray
		log vSelectedRows
		set vRows2Switch to (vSelectedRows's allObjects()) as list
		repeat with vRow in vRows2Switch
			set vRow2Move to vArrangedDS's objectAtIndex_(vRow)
			--set vPlugStatus to (vRow's valueForKey_("plugswitch")) as boolean
			set vPlugName to (vRow2Move's valueForKey_("plugname"))
			log vPlugName
		end repeat

Where plugstable is just the table en the theDParray the array…
But I’ll try to ask the array controller for selectedObjects()…

#15

I know, we’re not the only ones finding this transition a little bit hard to learn.

#16

There are two ways to the user can use the application I’m working on: by clicking on a checkbox column or to select mulitple rows and use a menu item.

The code now i:

set vSelectedRows to theDParray's selectedObjects()
		if (count vSelectedRows) is 1 then
			set vClickedRow to plugstable's clickedRow() as integer
			set vArrangedDS to arrangedObjects of theDParray
			set vRow2Move to vArrangedDS's objectAtIndex_(vClickedRow)
			--set vPlugStatus to (vRow's valueForKey_("plugswitch")) as boolean
			set vPlugName to (vRow2Move's valueForKey_("plugname"))
			log vPlugName
		else if (count vSelectedRows) > 1 then
			log vSelectedRows
		else if (count vSelectedRows) is 0 then
			log "no row selected!"
		end if

This works well, but there will probable be a better way to script this nicely…

But I'll try to ask the array controller for selectedObjects()...

Letting the controller do the work is the way to go.

Hi,

I know this thread goes back some time but I was looking for information on getting an array of objects from a table.

This was not discussed here but seems to do the trick:

		

set tIndexSet to pTransactionTable's selectedRowIndexes()
		
set tArray to pRecordData's objectsAtIndexes_(tIndexSet)
		
log tArray

This returns an array containing the selected objects. It may be useful to someone.

All the best

Hi,

A follow up to previous code snippet:

This gets the selections from the table.(tIndexSet)

Then it gets a new array containing the objects, in this case from the array pRecordData.

Then it repeats through the array of recs (each tRec is an NSMutableDictionary)

It then changes a key value to the title of a popup menu.

Then it writes the record back into the array and finally reloads the data into the table.


	on chooseCategory_(sender)
		
		set tIndexSet to pTransactionTable's selectedRowIndexes()
		
		set tArray to pRecordData's objectsAtIndexes_(tIndexSet)
		
		repeat with tRec in tArray
			set tIndex to pRecordData's indexOfObject_(tRec)			
			set tValue to pCategoryMenu's title()
			set tKey to "category"
			tRec's setValue_forKey_(tValue,tKey)
			pRecordData's replaceObjectAtIndex_withObject_(tIndex,tRec)
		end repeat
		
		pTransactionTable's reloadData()

	end chooseCategory_

All the best

Terry
