    <p>Why not just set the properties of the text field's <a href="http://developer.apple.com/mac/library/documentation/cocoa/conceptual/TextEditing/Tasks/FieldEditor.html" rel="noreferrer">field editor</a> directly when the field <a href="http://developer.apple.com/mac/library/documentation/cocoa/reference/ApplicationKit/Classes/NSResponder_Class/Reference/Reference.html#//apple_ref/occ/instm/NSResponder/becomeFirstResponder" rel="noreferrer">becomes first responder</a>? </p> <p>In a typical text field, selection is only visible when the field is first responder, so if you ask for the text field's field editor, then set <em>its</em> selected text attributes, you'd get the same affect, wouldn't you?</p> <pre><code>NSDictionary * attributes = [NSDictionary dictionaryWithObjectsAndKeys: [NSColor orangeColor], NSBackgroundColorAttributeName, nil]; NSTextView * fieldEditor = (NSTextView *)[[self window] fieldEditor:YES forObject:textField]; [fieldEditor setSelectedTextAttributes:attributes]; </code></pre> <p><strong>Note:</strong> As discussed in the comments below, the documentation is correct in saying the field editor is an instance of NSTextView, but the -[NSWindow fieldEditor:forObject:] method claims to return an NSText (NSTextView's immediate superclass). If you plan to send the field editor NSTextView-only methods, you'll need to cast it as an NSTextView to quiet the compiler's warnings. The casting won't break anything in your code, should the method prototype be corrected in the future, so it can safely be left in place.</p>

    1. COTake a look at this answer to another question. It shows how to manipulate the field editor for an NSTokenField (which is a subclass of NSTextField, so it works exactly the same way). http://stackoverflow.com/questions/2995205/prevent-selecting-all-tokens-in-nstokenfield

    2. COThe text field's field editor is an NSText object, and that class doesn't have the setSelectedTextAttributes method either. Unless I'm missing something, it doesn't seem like it can be done this way.

    3. CO@hasvn: This is confusing... the prototype for `-[NSWindow fieldEditor:forObject:]` says it returns `NSText*`, but the documentation says that the field editor is an NSTextView object.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
