Hi there,
Not sure how much I can help, but I do have some different predicate rows that
seem to work for me:
class StepperRowTemplate : NSPredicateEditorRowTemplate {
override var templateViews: [NSView] {
get {
let XVPredicateRowStepperOffset = CGFloat(8)
v

Hello list,
I’ve encountered a bug for the life of me I can’t work out. I’m restricted to
supporting Mojave (10.14) for the time being, so it is possible this has been
fixed / not an issue on later releases. This is a Core Data backed application,
with several Xib loaded views that are swapped

Hello Cocoa List,
I’m in the process of porting a hobby project to up-to-date Swift so it can be
used on Catalina (and I can upgrade my work machine - still looking for a
QuickTime 7 Pro replacement, though). I’ve encountered a phenomenon

Hello list,
Anyone know if it is intentionally the case that NSTableView doesn’t call
dragImageForRows(with dragRows: IndexSet, tableColumns: [NSTableColumn], event
dragEvent: NSEvent, offset dragImageOffset: NSPointPointer) -> NSImage
if you implement

Hello list,
After putting it off for too long, I’m migrating to view-based NSTableViews.
I’ve worked through most of the conversion problems I’ve had, and am generally
pretty happy. There is, however, one problem I haven’t been able to solve.
I have a NSButton in the same window as my table.

Thank you both for responding. I am pretty sure I have everything linked up

I have a modular single window application, where it has become necessary to
put control code into NSViewController subclasses.
I have googled extensively on this issue, and it seemed pretty easy. The
solution I went with is here:

Dear Dev List,
I've noticed strange window resizing behaviour the last couple of weeks,
possibly since I upgraded to Mountain Lion. This may also be a resolution
thing, as I've only tried this on a Retina MacBook.

I've been reworking my application and I've found a solution I'm not
particularly happy with, and was hoping to get some advice from others.
I have several views that are essentially views onto different tables. Each

Dear Cocoa List,
I'm occasionally seeing a crash when a XIB is loading some of the bindings I've
set up. Using a NSViewController subclass, a view is loaded in response to
clicking on a NSToolbar item. One of the views displays some disk space usage
information. This works fine almost all of
