    <p>I would like to enter text in a <code>NSTextView</code> so that when I hit return the <code>NSTextView</code> clears with the cursor going back to the original position. Then the entered text displays on the screen using the <code>drawRect</code> of an <code>NSView</code>.</p> <p>This what I have currently which doesn't work. Basically <code>self.outputString</code> is always the current value of <code>[textview string]</code> even though I draw and then clear. The current code below doesn't draw any string to the screen. If I remove <code>[textview setString:@""]</code> then the current text always shows what I'm writing. </p> <pre><code>- (void)drawRect:(NSRect)dirtyRect { [[NSColor whiteColor] setFill]; NSRectFill(dirtyRect); // Drawing code here. NSPoint point = NSMakePoint(50.0f, 700.0f); NSMutableDictionary *font_attributes = [[NSMutableDictionary alloc] init]; NSFont *font = [NSFont fontWithName:@"Futura-MediumItalic" size:35.0f]; [font_attributes setObject:font forKey:NSFontAttributeName]; [self.outputString drawAtPoint:point withAttributes:font_attributes]; [font_attributes release]; } - (BOOL)textView:(NSTextView *)textView doCommandBySelector:(SEL)commandSelector { [self enterPressed:[textView string]]; [textView setString:@""]; NSRange range = { 0, 0 }; [self.textView setSelectedRange: range]; return YES; } - (void) enterPressed:(NSString*)stringEntered { NSLog(@"enter pressed with string: %@", stringEntered); self.outputString = stringEntered; [self setNeedsDisplay:YES]; } </code></pre>

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.
