    <p>I have a layout with several NSButton object, and a NSTextField where the text is only selectable. The other NSButton objects have key-bindings associated, and this works perfectly until I select some text in the textfield. From there on the key bindings for the other buttons in the layout do not work anymore. </p> <p>I have looked at different solutions, like trying to set SetSelectable:NO and YES, but it seems like the text field keeps its focus and receives all the keystrokes even if it's not editable. </p> <p>I want the text in the textfield to be selectable, but if one of the other buttons is clicked, the textfield should stop receiving key-events. </p> <p>Any ideas? </p> <hr> <p>I Found a solution to this. </p> <p>At Macrumors: <a href="http://forums.macrumors.com/showthread.php?t=852807" rel="nofollow">http://forums.macrumors.com/showthread.php?t=852807</a></p> <p>I found a method, for checking if a textfield has focus: </p> <pre><code>- (BOOL)isTextFieldInFocus:(NSTextField *)textField { BOOL inFocus = NO; inFocus = ([[[textField window] firstResponder] isKindOfClass:[NSTextView class]] &amp;&amp; [[textField window] fieldEditor:NO forObject:nil]!=nil &amp;&amp; [textField isEqualTo:(id)[(NSTextView *)[[textField window] firstResponder]delegate]]); return inFocus; } </code></pre> <p>Then in the Update method that is executed on all the NSButtons, I wrote: </p> <pre><code>if ([self isTextFieldInFocus:display]) { [display setHidden:YES]; [display setHidden:NO]; } </code></pre> <p>where display, is the name of the NSTextField outlet. </p> <p>Now, when I select some text, and then press one of the buttons, the key-bindings on the NSButtons are back in place working. This allows the user to select and copy text, but then he has to push one button to enter keystrokes, and this I think is OK. </p>

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.
