Global Data Structures

The Photon API defines various data types and structures:

• If you're using the Photon Application Builder (PhAB), the appropriate header files are automatically included in your application.
• If you're not using PhAB, include <Pt.h>.

This chapter describes the data structures listed below:

PtBalloonCallback_t

Balloon callback structure

PtCallback_t

Regular callback structure

PtCallbackInfo_t

Specific callback information

PtHotkeyCallback_t

Hotkey handler structure

PtRawCallback_t

Event handler structure

The following datatypes are described in the Photon Library Reference:

ApBitmap_t

PhAB bitmap structure

ApInfo_t

PhAB information structure

PgColor_t

Composite color value

PgColorHSV_t

Hue-Saturation-Value color value

PhArea_t

Position and dimensions of a rectangular area

PhDim_t

Dimensions of an area

PhClipHeader
