Detailed Description

Class to store the a value that is either a constant or a ratio.

You don't have to explicitly create an instance of this class, numbers and strings are implicitly cast.

Member Function Documentation

◆ getRatio()

constexpr float tgui::AbsoluteOrRelativeValue::getRatio ( ) const
inlineconstexpr

Returns the stored ratio.

Returns
The ratio that is multiplied with the parent size to get the value, when the value isn't a constant

◆ getValue()

constexpr float tgui::AbsoluteOrRelativeValue::getValue ( ) const
inlineconstexpr

Returns the value.

Returns
The constant value or the value based on the given ratio and parent size

◆ isConstant()

constexpr bool tgui::AbsoluteOrRelativeValue::isConstant ( ) const
inlineconstexpr

Returns whether the value is constant or a ratio.

Returns
Does the value contain a constant?
