Hi! I am using a custom editor when editing the contents of a cell inside a Table view. From the docs I see that the custom editor has to be an NSTextView. So I put the text view in the document view, then I referenced it from the cell subclass through an IBOutlet in order to assign it as custom editor. When doing all this, I can set t...
I'm wondering how one would implement an outline view like the one Xcode 3 is using for the build configuration: When using an NSOutlineView/NSTableView with bindings and an NSTreeController/NSArrayController, the view's columns get bindings assigned to, not the individual cells, for obvious reasons. If every row in a column uses the ...

When I restart my Core Data application with a to-many relationship my data (presented in NSTableView) is in random order. How do I keep it in that order in which the user left it before quitting the application?

Hi, I've been attempting this for two days, and constantly running into dead ends. I've been through Aaron Hillegass's Cocoa Programming for MAC OS X, and done all the relevant exercises dealing with NSTableview and mutable arrays, and I have been attempting to modify them to suit my needs. However none of them seem to be using an ar...
Hey experts, when I click on the header of an NSTableView column, the header gets blue and the little grey arrow shows up.

Hello, I am trying to create a sectioned NSTableView using bindings with an NSArrayController or multiple NSArrayControllers. Basically the data container is an array within an array. Do I bind an NSArrayController to the parent collection and then bind another NSArrayController to a child collection? Is this the right approach? Thank...
Hello, I am trying to understand the meaning of clipRect in a table view embedded inside a scroll view. I assumed that the clip rect is the visible portion of the table view. This means that the width of the rect should not change as long as the table view is not resized, but upon monitoring the width of the clip rect in the following c...
Hey experts, When I drag rows from an NSTableView to another NSOutlineView, the NSOutlineView gets a yellow highlighting border. How do I avoid that? To be precise, this happens only if I drag the rows from the table into the free space (i.e. not on any items) of the NSTableView. However, when I drag the rows directly on items in the N...
I'm trying to find a way to get an NSImage (or CGImage or CIImage, I'm not picky) containing only the visible rect portion of an NSTableView. I've tried this: NSRect visiblePart = [someTable visibleRect]; NSImage *tableImage = [[NSImage alloc] initWithSize:tableFrame.size]; [tableImage lockFocus]; [someTable drawRect:visiblePart]; [ta...

I've got an NSTableView with a single column, populated with NSTableViewDataSource methods (no bindings involved.) The NSTableView is inside an NSScrollView, as is the default behavior when you drag an NSTableView in from the library in Interface Builder. The contents of the tableview are populated based upon a search string that the use...

Whenever I do: xxx = [NSImage imageNamed:@"Package.png"]; xxx loads but it's width and height remain 0.

I'm making a custom view that I want to be bindings/core data compatible and represent a collection of data (a la NSTableView) Is there any way my view can refer to a specific subset of the elements in the collection (other than the current selection) after a change by the user? A bit of context: The view is going to display a number o...
