Detailed Description

Common part of all widgets and views.

Todo:: Find a way to make the callbacks respect subtypes? Currently type-specific callbacks need to have their self argument defined as ui_component_t * (or void * if we opt to do that) which is a bit less ideal.

Field Documentation

◆ footprint

ui_rect_t ui_component_s::footprint

Component visual footprint.

This defines the size and location of the component on screen.

◆ next

ui_component_t* ui_component_s::next

Next component in a component ring or list.

This will be set to NULL when initialized, and, depending on context, will be a pointer to the next component, a pointer to this component or NULL.

◆ on_erase_bg

void(* ui_component_s::on_erase_bg) (ui_component_t *self)

Component callback for erasing background.

Todo:: Figure out exactly what this does.

◆ parent

ui_component_t* ui_component_s::parent

Parent component.

This will usually be a view.

◆ state

unsigned short ui_component_s::state

Component state bit field.

Each component may use this differently to represent different states.

◆ tag

unsigned short ui_component_s::tag

Component tag. Can be used to distinguish components under some circumstances (like when sharing a callback with another component). Does not need to be unique. Usually will be set by AllocBlock() after the memory was allocated.

The documentation for this struct was generated from the following file:

include/muteki/ui/common.h
