[70068 Closed] Nougat: UILayoutPriority enum missing?

Elements C#
1

It seems that the UILayoutPriority enum is missing. It’s defined as

enum {
UILayoutPriorityRequired = 1000,
UILayoutPriorityDefaultHigh = 750,
UILayoutPriorityDefaultLow = 250,
UILayoutPriorityFittingSizeLevel = 50,
};
typedef float UILayoutPriority;

in NSLayoutConstraint.h. There are no CC options given for UILayoutPriority.UI… and using (for example) UILayoutPriority.UILayoutPriorityRequired gives an error (error E43: No static member “UILayoutPriorityRequired” on type “UILayoutPriority”).

Hmm, a float enum? we probably don’t handle this properly.

Thanks, logged as bugs://70068: Nougat: UILayoutPriority enum missing?

I worked around by adding:

private enum UILayoutPriorityConstants : Integer {
	UILayoutPriorityRequired = 1000,
	UILayoutPriorityDefaultHigh = 750,
	UILayoutPriorityDefaultLow = 250,
	UILayoutPriorityFittingSizeLevel = 50,
};

at the top of the class and it seemed to work OK to pass into methods that needed them. It looks like the C enum is a standard integer enum but the typedef is a float.

This is only sort of fixed on 1645. The enum constants are defined individually but not as part of an enum. For example this works

fTitleLabel.setContentHuggingPriority(UILayoutPriorityRequired) forAxis(UILayoutConstraintAxis.UILayoutConstraintAxisVertical);

but this doesn’t

fTitleLabel.setContentHuggingPriority(UILayoutPriority.UILayoutPriorityRequired) forAxis(UILayoutConstraintAxis.UILayoutConstraintAxisVertical);
