Detailed Description

This class provides the value and change notifications for the properties of a single setting.

Since setting values and other properties are provided by a stack, we need some way to query the stack from QML to provide us with those values. This class takes care of that.

This class provides the property values through QObject dynamic properties so that they are available from QML.

Member Function Documentation

◆ getPropertyValue()

def UM.Settings.Models.SettingPropertyProvider.SettingPropertyProvider.getPropertyValue (   self,
  property_name,
  stack_level 
)

Manually request the value of a property.

The most notable difference with the properties is that you have more control over at what point in the stack you want the setting to be retrieved (instead of always taking the top one)

Parameters
property_nameThe name of the property to get the value from.
stack_levelthe index of the container to get the value from.

◆ setPropertyValue()

def UM.Settings.Models.SettingPropertyProvider.SettingPropertyProvider.setPropertyValue (   self,
  property_name,
  property_value 
)

Set the value of a property.

Parameters
stack_indexAt which level in the stack should this property be set?
property_nameThe name of the property to set.
property_valueThe value of the property to set.
