Re: Safari downloader-like behavior

2011-12-10 Thread Scott Anguish
If you’re working on a fairly recent OS, it’s much easier to use NSCollectionView for this. getting progress views into tableviews (except view based table views in Lion) is not trivial. But either a table view or collectionview would work in this case. I’d opt for collection view most likely.

NSTextField odd background colour behaviour

2011-12-10 Thread Peter Hudson
Hi All I have an NSTextField in an app. For some years I have set the background colour with, not unsurprisingly, setBackgroundColor: Recently I noticed that when attempting to set the BG colour instead of the whole area of the text field changing colour, I get a thin line of colour chang

Just to make sure: are you certain that the text field is not being edited (and therefore obscured by the field editor) when you set the bg color? On Dec 10, 2011, at 3:50 AM, Peter Hudson wrote: > Hi All > > I have an NSTextField in an app. For some years I have set the background > colou

Re: NSTextField odd background colour behaviour

2011-12-10 Thread Peter Hudson
The text field is in a sheet and the order of the code that shows the sheet and then sets the bg Color has been the same for a long time. Strangely, exacly the same ui and code is used elsewhere and it works perfectly. How could I check if the field editor was covering the text field ? How c

AU Cocoa GUI sometimes not showing up

2011-12-10 Thread Vojtěch Meluzín
Hi, I have a really weird problem - in AudioUnits the Cocoa GUI is available like this - host asks the plugin for information about the objc class that creates the GUI, creates the object, asks it to create the GUI. But on some computers the GUI just don't show up, or even weirder it does NOT show

Custom View for hierarchy -- NSTreeController or Data Source?

2011-12-10 Thread John Velman
(Using Xcode 4.2, writing for OS X Lion) I have a hierarchy of stuff I want to display (at the same time) in both outline view and a custom view. Sort of analagous to the Buck and Yacktman (Cocoa Design Patterns) example in CH. 29, but with Outline instead of Table. I'll most likely have a detail
