I have a table with two columns, labeled "Key" and "Value" bound to

Now I want to select a row programmatically (e.g.
[ myDictionaryController selectRowWIthKey: @"someKey" ]; ).
But such a method I cannot find.
There is no such facility, unfortunately. It would be nice. Why not
file an enhancement request?
And trying to use the inherited "selectObjects:" does not work
(nothing happens, not even an error message).
Well, -selectObjects: can't be used to change a controller's
selection, so no wonder you aren't getting anywhere.
Sorry about this. It was setSelectedObjects: which I tried.
So: how can I select a row in my table?
Normally, -setSelectedObjects:, -setSelectionIndex:, or -
setSelectionIndexes:. If they don't work, and you want help with
that, then be specific about what precisely you tried (i.e. show
code!).
Here it is:
NSArray *defs = ...some array... (which is bound to content of
definitionsArrayController)
NSUInteger defIndex = 0;
for( NSDictionary *aDef in defs )
{
for( NSString *defKey in aDef )
{
NSString *value = [ aDef objectForKey: defKey ];
BOOL ok = ... some test with value
if ( !ok ) // select the bad thing
{
[ definitionsArrayController setSelectionIndex: defIndex ]; // this
works fine
// now the table shows "aDef" and the first row in the table is
selected
[ myDictionaryController setSelectedObjects: [ NSArray
arrayWithObject: defKey ] ];
// now no row is selected
return NO;
};
};
defIndex++;
};
It also helps to mention what you expect to happen, and what is
actually happening differently than your expectation.
Well: there is this table bound to myDictionaryController. And I would
expect that the row which contains defKey would be selected, but
nothing is selected instead.
This code works (but seems incredibly complicated and inefficient):
NSArray *arrangedObjects = [ dictController arrangedObjects ];
id theThing = nil;
for( id something in arrangedObjects )
{
NSString *key = [ something key ];
if ( [ key isEqualToString: defKey ] )
{
theThing = something;
break;
};
};
if ( theThing == nil ) // error
{
NSLog(@"%s Error not found",__FUNCTION__);
}
else
{
[ dictController setSelectedObjects: [ NSArray arrayWithObject:
theThing ] ];
};
Kind regards,
Gerriet.
