Struct zng_wgt_style::StyleMix
source · pub struct StyleMix<P>(/* private fields */);Expand description
m Styleable widget mixin.
Widgets that inherit this mix-in have a style_fn property that can be set to a style_fn!
that generates properties that are dynamically injected into the widget to alter its appearance.
The style mixin drastically affects the widget build process, only the style_base_fn, style_fn and when condition
properties that affects these are instantiated with the widget, all the other properties and intrinsic nodes are instantiated
on init, after the style is generated.
Widgets that inherit this mix-in must call style_intrinsic in their own widget_intrinsic, the call is missing
the widget will log an error on instantiation and only the style_base_fn will be used. You can use the impl_style_fn!
macro to generate the style var and property.
