View

A drawable region that receives events.

A view can be thought of as a window, but does not necessarily correspond to a top-level window in a desktop environment. For example, a view can be embedded in some other window, or represent an embedded system where there is no concept of multiple windows at all.

enum PuglViewHint

A hint for configuring a view.

enumerator PUGL_USE_COMPAT_PROFILE

Use compatible (not core) OpenGL profile.

enumerator PUGL_USE_DEBUG_CONTEXT

True to use a debug OpenGL context.

enumerator PUGL_CONTEXT_VERSION_MAJOR

OpenGL context major version.

enumerator PUGL_CONTEXT_VERSION_MINOR

OpenGL context minor version.

enumerator PUGL_RED_BITS

Number of bits for red channel.

enumerator PUGL_GREEN_BITS

Number of bits for green channel.

enumerator PUGL_BLUE_BITS

Number of bits for blue channel.

enumerator PUGL_ALPHA_BITS

Number of bits for alpha channel.

enumerator PUGL_DEPTH_BITS

Number of bits for depth buffer.

enumerator PUGL_STENCIL_BITS

Number of bits for stencil buffer.

enumerator PUGL_SAMPLES

Number of samples per pixel (AA)

enumerator PUGL_DOUBLE_BUFFER

True if double buffering should be used.

enumerator PUGL_SWAP_INTERVAL

Number of frames between buffer swaps.

enumerator PUGL_RESIZABLE

True if view should be resizable.

enumerator PUGL_IGNORE_KEY_REPEAT

True if key repeat events are ignored.

enumerator PUGL_REFRESH_RATE

Refresh rate in Hz.

enumerator PUGL_ACCEPT_DROP

True if view accepts dropped data.

enumerator PUGL_NUM_VIEW_HINTS

enum PuglViewHintValue

A special view hint value.

enumerator PUGL_DONT_CARE

Use best available value.

enumerator PUGL_FALSE

enumerator PUGL_TRUE

typedef struct PuglViewImpl PuglView

A drawable region that receives events.

typedef struct PuglBackendImpl PuglBackend

A graphics backend.

The backend dictates how graphics are set up for a view, and how drawing is performed. A backend must be set by calling puglSetBackend() before realising a view.

If you are using a local copy of Pugl, it is possible to implement a custom backend. See the definition of PuglBackendImpl in the source code for details.

typedef uintptr_t PuglNativeView

A native view handle.

X11: This is a Window.

MacOS: This is a pointer to an NSView*.

Windows: This is a HWND.

typedef void *PuglHandle

Handle for a view’s opaque user data.

typedef PuglStatus (*PuglEventFunc)(PuglView *view, const PuglEvent *event)

A function called when an event occurs.
