SIMPLIFIED:
I have the following:
NSWindow (this is the main window of the app)
NSPanel (this is presented as a sheet, over the main NSWindow, using [NSApp beginSheet:)
The main NSWindow has a subclassed NSButton that uses mouse events, including mouseEntered, mouseExited. This changes the background color of the button as I hover over it.
I present my NSPanel, this also has an NSButton of the same subclass, to change color on hover.
Mouse events still occur in the main NSWindow while my NSPanel is presented. I can tell this, as hovering over the buttons still works.
However, hovering over the buttons in the presented NSPanel does not work, despite them being no different from the other buttons. I can click on them and they receive an action. But they do not call the mouse events.
ORIGINAL:
I have a simple setup in my Mac app. I have a main NSWindow, as any usual mac app, then I run the following code which displays my detail view.
My detail view is an NSWindowController subclass and I am displaying it as a sheet. This is setup as an NSPanel in the xib and just displays a detail view for me over my main window.
APDetailWindowController *vc = [[APDetailWindowController alloc] initWithWindowNibName:#"APDetailWindowController"];
self.detailWindowController = vc;
self.detailWindowController.delegate = self;
APAppDelegate *appDelegate = [[NSApplication sharedApplication] delegate];
[NSApp beginSheet:self.detailWindowController.window modalForWindow:appDelegate.window modalDelegate:self didEndSelector:nil contextInfo:nil];
In my main window (of the AppDelegate), I have my views played out as any app, including some NSButtons. These buttons are subclassed so that when they receive mouseEntered and mouseExited events, they change colour. Basically creating a rollover effect.
In my detail view, I also have buttons of the same subclass. However, they are not receiving the mouse events at all. I can see when moving my mouse over them nothing happens. Even when the detail view is displayed, the rollover works on the main window buttons in the background, but not in my detail view.
I am thinking maybe some sort of focus is still on the main window and needs to be set to the detail window?

I have a generic NSPanel window that I am using as a preferences window in my app. I have a selector that I call every time the window closes. The purpose of that selector is to save the state of the users chosen preferences (there is no "save" button).
I have an NSButton ("CLOSE") which I easily setup to call my closing selector.
I set it up so that my selector is also called when the user clicks the RED X in the top left corner of the NSPanel by doing:
NSButton *closeButton = [[self window] standardWindowButton:NSWindowCloseButton];
[closeButton setTarget:self];
[closeButton setAction:#selector(myCloseSelector:)];
This works perfectly. My problem though? The window also closes if the user clicks outside of the NSPanel. E.g. If they take their mouse and click on their browser window below the NSPanel that popped up. This also closes the window.
How do I catch my NSPanel losing focus and closing ? I need to ensure that when this happens I also get my selector called.
Thanks!
Made my NSWindowController a delegate for NSWindowDelegate.
myWindowController.h
#interface myWindowController : NSWindowController <NSWindowDelegate>
and then set myWindowController as the delegate for my NSPanel.
Now I can implement:
- (void) windowDidResignKey:(NSNotification *)notification {
NSLog(#"Houston...we lost a panel.");
}
and everything works swimmingly!
I've developed for Mac before but this is the first time I've attempted to use the NSPopover control, which seemed like a great idea to start out with but so far is causing me no end of problems. The applciation is a menu bar application. I have two NSButton objects in the NSPopover's view controller, the NSPopover is being created programmatically in another subclass of NSButton, the same button which it is being shown relative to. This NSButton that it is being shown relative to is contained along with some other buttons in an NSMenuItem
The popup, containing the two buttons, is being shown fine (see screenshot below), however, despite the 'Yes' button being highlighted with a focus ring, neither button responds to click events, they do not even graphically click in like I would expect them to.
And this is the code that creates the NSPopover and positions it onscreen:
someViewController *confirmationDialogue = [[someViewController alloc] initWithNibName:#"someViewController" bundle:nil];
popOver = [[NSPopover alloc] init];
[popOver setBehavior:NSPopoverAppearanceMinimal];
[popOver setBehavior:NSPopoverBehaviorTransient];
[popOver setContentViewController:confirmationDialogue];
[popOver showRelativeToRect:NSMakeRect(0, 0, self.frame.size.width, self.frame.size.height))
ofView:self
preferredEdge:NSMaxYEdge];
Has anyone got any kind of solution/workaround to this?
Thanks in advance :)
P.s. This is my first question on SO, so I hope I've provided enough information but I'll give any more details as needed.
I'd like to display an NSWindow when right clicking an item in an NSTableView, similarly to how the available outlets are shown in Interface Builder when you right click an object:
Unfortunately you can only use an NSMenu subclass as the menu property.
I also didn't find a delegate method of NSTableView that notifies about right clicks.
I was able to subclass NSTableView and implement rightMouseDown: and rightMouseUp: to be notified about those events, but if I set the menu property of the row cells to nil, they are not highlighted when right clicked, even though I call the super implementation):
- (void)rightMouseDown:(NSEvent *)theEvent {
[super rightMouseDown:theEvent];
NSPoint eventLocation = [theEvent locationInWindow];
eventLocation = [self convertPoint:eventLocation fromView:nil];
NSInteger rowIndex = [self rowAtPoint:eventLocation];
NSLog(#"Right clicked at row index %d", rowIndex);
}
I would like to have the highlight effect in the image below but display a window instead of the context menu:
First for the right click: explicitly select the row on right click (e.g. via this message). Then create your own NSWindow descendant, set an own NSView class as contentView and in the view you can draw the black background, rounded borders and what not. Show this window in your right click handler.
You can use an NSPopover, which works quite nicely. A popover creates a window for you, even if it is somewhat hidden. You'll get it from your controls if you send them the window message, and can register to listen for events, for instance.
The whole popover can be created in IB, and just have to implement the showRelativeToRect:ofView:preferredEdge: method in code.
To catch the right click event, you can use rightMouseDown:, which is originally defined in NSResponder, but is overridden in NSView to simply catch the event and show menu and it doesn't pass the event upwards in the responder chain (or the inheritance chain, for that matter). Hence, you simply implement that method to call showRelativeToRect:ofView:preferredEdge:.
You will typically need to have the contents in an NSViewController and its own accompanying nib file.
The NSPopover's contentViewController property can be set in IB, too.
All in all, not much code needed.
This tutorial is useful.
I have a NSPanel in my MainMenu.xib called filePanel, it has a NSView called filePanelView. When buttons are clicked, I will load a NSView from a nib and add it to the filePanel like this:
[NSApp activateIgnoringOtherApps:YES];
[filePanel setIsVisible:YES];
[filePanelView addSubview:[fileBrowseViewController browseView]];
The problem is that the controls on these subviews can never be brought into focus. For example, a NSTextfield that is set to be editable is not editable, and doesn't have a focus ring around it when clicked. I can click buttons though. But on another window, a determinate progress bar has it's progress measured in grey instead of blue. Is there something I'm doing wrong in terms of needing to manually set these views as having focus?
I'm working in an iPad app that has a split view with a navigation controller in the detail view. The deepest view that can be in the navigation stack is an edit view where the user can edit data. I put an edit button as the rightBarButtonItem and when editing starts, change it to a done button.
When editing commences and the user touches on a particular field, I present a popoverview with a list of possible choices filtered by what they are typing - a form of autofill based on all the values of that field in all other objects.
This works fine, except if you try touching on the done button. The popover eats this touch and dismisses itself. So the user has to touch done again.
I tried using the uipopovercontroller's passthroughViews property, but UIBarButtonItem is not a view and there is no documented way to get the view for the done button or even the navigation bar. I can access the variable in gdb, but it isn't accessible via KVC.
Any ideas on how I can prevent the need to tap done twice?
I've thought about a gesture recognizer on the window, but that seems messy and I'd have to handle rotation.
In case anyone gets here from google, copypaste from other question:
The only solution I found for now is to create UIBarButtonItem with custom UIButton using
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
//code for styling button
UIBarButtonItem *b = [[[UIBarButtonItem alloc]
initWithCustomView:button]
autorelease]
and then
popoverController.passthroughViews = [NSArray arrayWithObject:b.customView];
But be prepared - you cannot create UIButton that looks like UIBarButtoItem. I ended up with creating image that reassembled UIBarButtonItem.
