Types

µGFX allows to write applications (eg. GUIs) that are completely portable as the library itself is highly agnostic. To achieve this goal, users should rely on the types exposed by µGFX as much as possible to prevent problems when migration to different systems.

Pre-Processor

For pre-processing related boolean operations (eg. #if MY_FEATURE) use GFXON and GFXOFF accordingly.

Basic

Type	Description
gBool	A boolean value. Use gTrue and gFalse for assignments & comparisons respectively.
gI8	Signed integer at least 8 bits wide.
gU8	Unsigned integer at least 8 bits wide.
gI16	Signed integer at least 16 bits wide.
gU16	Unsigned integer at least 16 bits wide.
gI32	Signed integer at least 32 bits wide.
gU32	Unsigned integer at least 32 bits wide.

System

Type	Description
gTicks	Type to represent a number of system ticks.
gDelay	Type to represent a a delay. The unit depends on the semantics for example number of ticks or milliseconds.
gMemSize	Type to represent a size of memory (in bytes).
gFileSize	Type to represent the size of a file (in bytes).

Rendering

Type	Description
gCoord	A type to express a coordinate in pixels.
gColor	A color.
gFont	A font. See font rendering.
gImage	An image. See images.
