    <p>I am using NSSplitview of which upper half is NSTableView and lower is NSTabview with 2 items. Each NStabViewItem has a NSTextview. All are defined in nib file.</p> <p>Now on selection of row of NSTableview, I load content of file and set it on NSTextview of NSTabViewItem. so NSTabview items I load depending on what rows of NSTableView is selected.</p> <p>However I observe appreciable delay of 5-6 seconds to see the text visible on NSTextview of NSTabViewItem of NSTabView.But if I hover the mouse in the NSTabView region the content of NSTextview of NSTabViewItem of NSTabview is shown immediately. Can anybody guide me what is the issue?</p> <p>I am only using NSTableView delegate, Not tabview delegate. I just load the content in respective NSTextView of each NSTabViewItem of tabview.</p> <p>Code Snippet:</p> <pre><code> - (void)tableViewSelectionDidChange:(NSNotification *)notification { if ([mTableView selectedRow] != -1) { selectedNode = [mLogContainer objectAtIndex:[mTableView selectedRow]]; [self manageTabView:[selectedNode logfile]]; } } -(void) manageTabView:(NSString*) fname { [self loadTextView:mDetailView withFilePath:fname]; NSString* summaryFile = [NSString stringWithFormat:@"%@.summary",fname]; [self loadTextView:mSummaryView withFilePath:summaryFile]; [mTabView selectTabViewItemAtIndex:0]; } -(void) setContent:(NSString*) content forView:(NSTextView*) textView { NSString* fileContent = [[NSString alloc] init]; [fileContent stringWithContentsOfFile:content encoding:NSUTF8StringEncoding error:nil]; NSTextStorage *textStorage = [textView textStorage]; [textStorage beginEditing]; [[textStorage mutableString] setString:fileContent]; [textStorage endEditing]; [textView 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.
