How can I detect which tableview sent the notification?

Scripting Forums AppleScriptObjC and Xcode
#1

Hello friends,

I have two table views connected to the very same “on tableViewSelectionDidChange_(aNotification)” handler.

Question:

How can I detect which of the two table views was clicked?

I can get this:

<NSTableView: 0x102c28370>

When I have a line “log aNotification”.

But I don’t know how to insert this info in an “if” block to run different routines for each table view.

Thanks for any help.

Just assign IBOutlets to your two tables and use those names in your if statement, for example if your outlets were table1 and table2, you could just write:

if aNotification’s object is table1 then
–do something with table1
else
–do something with table2
end if

Any clues?

I can’t tell without seeing the code. Post the code where you implemented my lines.

Thanks my friend.

This is the full method:


on tableViewSelectionDidChange_(aNotification)
        
        log "table view selection has changed..."
        
        tell theArrayController to set theSel to selectedObjects() as list
        set xmlPathAsUrlString to convertPath_to_Url_(theXMLPaths of  item 1 of theSel)
        set pdfPathAsString to convertPath_to_Url_(thePDFPaths of item 1 of theSel)
        renderPdfOfSelectedRow_(xmlPathAsUrlString,pdfPathAsString)
         
         if aNotification's object is the_invoices_table then
             log "the_invoices_table"
         else 
             log "the_folders_table"
         end if
         
    end tableViewSelectionDidChange_

I pasted your code into my app and commented out the middle group of lines (between the first log statement and the if block) since I have no way to test those – the remaining code worked fine. Try commenting those lines out and see what happens.

I tried commenting the same lines, leaving just:



if aNotification's object is the_invoices_table then
             log "the_invoices_table"
         else 
             log "the_folders_table"
end if

I still get the same errors…

Please note I am using an array controller …

Did you make that method, tableViewSelectionDidChange_(aNotification), an IBAction for your table? It looks like from the error message that you are trying to get the value of “object” from the table view. I reread your first post, and it looks like that’s what you did. That’a not how delegate methods like “tableViewSelectionDidChange:” work. You don’t make this the action for your table view. You make your script the delegate of your two table views (from the connections pane in the inspector in IB), and then this method gets called by the table view when the selection changes.

I clicked in the little cube for my appDelegate then → Connections inspector → received actions , connected “tableViewSelectionDidChange:” to both tables.

That’s it.

Should I have done it differently?

The code works. I just can’t write further code to distinguish the tables.

If I just could convert “<NSTableView 0x103110170>” to some usable data…

#10

Thanks my friend!

I solved it.

I clicked on the table view, then connections → Outlets and linked “delegate” to my app delegates little cube.

Now it works.

#11

Hi,

<NSTableView 0x103110170> is usable data because it’s an object specifier.
If you have defined

property myTableView : missing value

and have connected the property in Interface Builder, you can identify the object
in the delegate method with with

if (aNotification's |object|() isEqualTo_(myTableView) then
-- do something with myTableView
end if
#12

Yes, as I said in my last post, you don’t connect delegate methods that way. You should delete those connections.

This is all you need to do for delegate methods, as far as connections are concerned.

Thanks rDelmar and Stefank.

You have been very helpful my friends…
