I have a table with 2 columns. The first column contains check boxes. I have discovered that setting the editable attribute of that column to false does not prevent the check boxes from being checked/unchecked by the user. How do I set the editable attribute of the check boxes of that column to be editable or not?
Example of non-working code:
set editable of table column "column1" of table view "theTable" of scroll view "theTable" of window "main" to false
If you want the buttons to be disabled (and grayed out) all of the time, then you can do something like this in the awake from nib handler of the table view…
on awake from nib theObject
set enabled of data cell of table column "Column" of theObject to false
tell theObject to update
end awake from nib
If you want to be able to toggle the ‘enabled-ness’ of the buttons, then you could do something on the “on clicked” handler, like this…
on clicked theObject
if name of theObject is "EnableButtons" then
tell table view "Table" of scroll view "Scroll" of window "Window"
set enabled of data cell of table column "Column" to (state of theObject)
update
end tell
end if
end clicked
Note that both of the above methods completely gray out the buttons. Because buttons (and button cells) don’t support an “editable” property… only text-bearing objects respond to editable… you can really only use the “enabled” property. If you want the buttons to look normal, but not be able to be changed, you could use the “change cell value” handler of the table view. This ONLY works when you’re constructing the table data without using a data source (with ‘number of rows’ and ‘cell value’ and a source list)…
set OKToChangeButtons to true
on change cell value theObject row theRow table column tableColumn value theValue
if (OKToChangeButtons) then
set item theRow of sourceList to theValue
end if
end change cell value
Use the handler to capture the value that the button has changed to, then change the corresponding list item to reflect that value. The handler automatically tells the cell to re-draw, and when it does it grabs the value from the list again and the new value is shown. The effectiveness of this method is greatly dependent on whether your setup is compatible with manipulating your data this way.
