I'm writing a signal processing program and I am trying to use a window to
display multiple NSViews of an oscilloscope, histograms, etc. I create the
NSTabViewItems programmatically. The window controller declares the following
properties:
@property(nonatomic, strong) IBOutlet NSWindow *analysis;
// the visualization window
@property(nonatomic, strong) IBOutlet NSTabView *myTabView;
// the host view
@property(nonatomic, strong) IBOutlet NSTabViewItem *scopeItem;
// the host view
@property(nonatomic, strong) IBOutlet NSTabViewItem *graphItem;
// the host view
@property(nonatomic, strong) IBOutlet NSTabViewItem *DSPItem;
// the host view
@property (nonatomic, strong) IBOutlet NSDrawer *scopeDrawer;
@property (nonatomic, strong) IBOutlet NSDrawer *graphFormatDrawer;
@property(nonatomic, strong) NSView *myCurrentView;
// the host view
@property(nonatomic, strong) NSViewController
*myCurrentViewController; // the current view controller
When I create the tab view items. I use in the window controller
-(void) awakeFromNib
{
[self setDelegate:self];
}
- (IBAction) viewScope:(id)sender
{
AppDelegate *appDelegate = [NSApp delegate];
if ([appDelegate oscilloscopeController] == nil){
[appDelegate setOscilloscopeController: [[OscilloscopeController
alloc]initWithNibName:@"OscilloscopeController" bundle:[NSBundle
bundleForClass:[OscilloscopeController class]]]];
NSLog(@"New Oscilloscope Controller Created by viewScope");
}
if ([appDelegate graphViewController] == nil) //Needed for
drawing grids, etc.
[appDelegate setGraphViewController: [[GraphViewController
alloc]initWithNibName:@"GraphViewController" bundle:[NSBundle
bundleForClass:[GraphViewController class]]]];
if ([[appDelegate oscilloscopeController] oScopeView] == nil){
[[appDelegate oscilloscopeController] setOScopeView:[[OscilloscopeView
alloc] initWithFrame: [[[appDelegate graphicsWindowController] myTabView]
contentRect]]];
NSLog(@"New Oscilloscope View Created by viewScope");}
if (!scopeItem){
[[appDelegate oscilloscopeController] initScopeSweep];
[[appDelegate graphicsWindowController] setScopeItem:
[(NSTabViewItem*)[NSTabViewItem alloc] initWithIdentifier:nil]];
[[[[appDelegate graphicsWindowController] scopeItem] view]
setAutoresizesSubviews:YES];
[[[appDelegate graphicsWindowController] scopeItem]
setLabel:@"Oscilloscope"];
[[[[appDelegate graphicsWindowController] scopeItem] view]
addSubview:(NSView*)[[appDelegate oscilloscopeController] oScopeView]];
[myTabView addTabViewItem:[[appDelegate graphicsWindowController]
scopeItem]];
}
[[[appDelegate graphicsWindowController]graphFormatDrawer] close];
[[[appDelegate graphicsWindowController]scopeDrawer] open];
[[appDelegate graphicsWindowController] setMyCurrentViewController:
[appDelegate oscilloscopeController]]; // keep track of the current view
controller
[[appDelegate graphicsWindowController] setMyCurrentView:
(NSView*) [[appDelegate oscilloscopeController] oScopeView]];
NSRect iRect = [[[appDelegate graphicsWindowController] myCurrentView]
bounds];
[[appDelegate oscilloscopeController] setDistOffset:(iRect.size.height/ 3)];
[[appDelegate oscilloscopeController] setProxOffset:((iRect.size.height /
3) * 2)];
[[[[NSApp delegate] graphicsWindowController] myCurrentView]
setNeedsDisplay:YES];
}
- (IBAction) viewGraph:(id)sender
{
AppDelegate *appDelegate = [NSApp delegate];
if ([appDelegate graphViewController] == nil)
[appDelegate setGraphViewController: [[GraphViewController
alloc]initWithNibName:@"GraphViewController" bundle:[NSBundle
bundleForClass:[GraphViewController class]]]];
if ([[appDelegate graphViewController] graphicsView] == nil){
[[appDelegate graphViewController] setGraphicsView:[[GraphicsView
alloc] initWithFrame: [[[appDelegate graphicsWindowController] myTabView]
contentRect]]];
NSLog(@"New Graphics View Created by viewGraph");}
if (![[appDelegate graphicsWindowController] graphItem]){
[[appDelegate graphicsWindowController] setGraphItem:
[(NSTabViewItem*)[NSTabViewItem alloc] initWithIdentifier:nil]];
[[[[appDelegate graphicsWindowController] graphItem] view]
setAutoresizesSubviews:YES];
[[[appDelegate graphicsWindowController] graphItem] setLabel:@"Graph"];
[[[[appDelegate graphicsWindowController] graphItem] view]
addSubview:(NSView*)[[appDelegate graphViewController] graphicsView]];
[myTabView addTabViewItem:[[appDelegate graphicsWindowController]
graphItem]];
}
[[[appDelegate graphicsWindowController]graphFormatDrawer] open];
[[[appDelegate graphicsWindowController]scopeDrawer] close];
[[appDelegate graphicsWindowController] setMyCurrentViewController:
[appDelegate graphViewController]]; // keep track of the current view
controller
[[appDelegate graphicsWindowController] setMyCurrentView:
(NSView*) [[appDelegate graphViewController] graphicsView]];
[[myCurrentViewController view] setFrame: [myCurrentView bounds]];
[[[[NSApp delegate] graphicsWindowController] myCurrentView]
setNeedsDisplay:YES];
}
I created a delegate procedure in the window controller
- (void)tabView:(NSTabView *)tabView didSelectTabViewItem:(NSTabViewItem
*)tabViewItem
{
AppDelegate *appDelegate = [NSApp delegate];
if (tabViewItem == [[appDelegate graphicsWindowController] scopeItem]){
NSLog(@"Scope Item Selected");
}
else if (tabViewItem == [[appDelegate graphicsWindowController] graphItem]){
NSLog(@"GraphItem Selected");
}
}
That never gets called. Hence my question about the target action of the tabs.
When I first create the oscilloscope tab the oscilloscope gets drawn,
but if I then create a graphViewItem it draws a blank screen. If I then click
on the oscilloscope tab, the oscilloscope image doesn't come back.
Thanks for your help.
