Detailed Description

class DIWNE::StyleBase;

Default base style.

Implementation of the Style interface.

Each NodeEditor contains a StyleBase member that contains the default style settings for objects inside that node editor. The base style can be modifed by setting a DiwneObject's StyleOverride.

Style variables are accessed using the StyleBase::get(key) method, key being one style variable enum values. Variables themselves are stored in a std::vector registry and accessed by the key (index based access). This is different from how, for example, ImGuiStyle works where each variable is just a plain variable in a struct.

The base style is DPI-aware. It has a dpiScale parameter to scale relevant style variables at runtime by the UI DPI scaling factor. Whether a particular theme variable will be scaled in that call depends on an internal dpiScaled flag that can be passed to the StyleBase::set() method during style initialization.

StyleBase::setDpiScale() should be called on DPI scale change.

Note that StyleBase variables are not automatically scaled by the DIWNENodeEditor zoom factor. This must be done manually on case by case basis inside DIWNE code.

typename std::enable_if< std::is_pointer< T >::value, bool >::type  =true>
inline void set(
    Style::Var key,
    T ptr,

)

Set style variable from a pointer, so that it can be modified dynamically.

Parameters:

• key Style variable key to set
• ptr Pointer to the style value, ownership will NOT be transferred (memory is managed externally)
• dpiScaled Whether to scale the style variable with dpi scaling.

function set

template <typename T ,
typename std::enable_if<!std::is_pointer< T >::value, bool >::type  =true>
inline void set(
    Style::Var key,
    T value,
    bool dpiScaled =false
)

Set style variable value.

Parameters:

• key Style variable key to set
• value Style value, passed as a copy. To pass a pointer see the pointer method overload.
• dpiScaled Whether to scale the style variable with dpi scaling.
