Properties | |
aqt::cassowary::Strength::Types | strength |
Sets the strength of a constraint. More... | |
double | weight |
Sets the weight of a constraint. More... | |
bool | when |
The constraint is enabled when this property holds a true value, otherwise it has no effect. | |
![]() | |
aqt::cassowary::Contextual | extend |
If non-null, this contextual will use the same context as used by this contextual. | |
Common abstract base of all constraint types, providing common properties and behavior.
aqt::cassowary::Strength::Types aqt::cassowary::ConstraintBase::strength |
Sets the strength of a constraint.
double aqt::cassowary::ConstraintBase::weight |
Sets the weight of a constraint.
The weight disambiguates the priority of constraints with the same strenght. Constraints with higher weight have higher priority.
