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)
var views = super.templateViews
(views.last! as! NSTextField).alignment = .right
var frame = views.last!.frame
frame.origin.x = frame.origin.x + frame.size.width +
XVPredicateRowStepperOffset
let stepper = NSStepper(frame: frame)
stepper.minValue = 0
stepper.valueWraps = false
stepper.bind(.value, to: views.last!, withKeyPath:
#keyPath(NSTextField.doubleValue), options:
[NSBindingOption.continuouslyUpdatesValue:true])
views.append(stepper)
return views
}
}
}
class DatePickerRowTemplate : NSPredicateEditorRowTemplate {
func newDateView() -> NSDatePicker? {
let XVDatePickerWidth = CGFloat(150)
let datePickerCell = NSDatePickerCell()
var frame = super.templateViews.last!.frame
frame.size.width = XVDatePickerWidth
datePickerCell.calendar = Calendar(identifier: .gregorian)
datePickerCell.datePickerMode = .single
datePickerCell.datePickerElements = .yearMonth
datePickerCell.dateValue = Date()
datePickerCell.isEditable = true
let datePicker = NSDatePicker(frame: frame)
datePicker.cell = datePickerCell
return datePicker
}
var dateView: NSDatePicker?
override func copy(with zone: NSZone? = nil) -> Any {
let newRow = super.copy(with: zone) as! DatePickerRowTemplate
newRow.dateView = newDateView()
if let _ = dateView {
newRow.dateView!.dateValue = self.dateView!.dateValue
}
return newRow
}
override var templateViews: [NSView] {
get {
let views = super.templateViews
let datePicker : NSDatePicker
if let _ = dateView {
datePicker = dateView!
}
else {
datePicker = newDateView()!
}
return [views[0], views[1], datePicker]
}
}
}
That sort of thing worked for me.
Regards,
Arved
