 DisplayRegion (GraphicsLayer *layer)
 DisplayRegion (GraphicsLayer *layer, const float l, const float r, const float b, const float t)
 DisplayRegion (int xsize, int ysize)

float get_left () const

void set_dimensions (float l, float r, float b, float t)
 Changes the portion of the framebuffer this DisplayRegion corresponds to.

GraphicsLayer * get_layer () const
 Returns the layer associated with this particular DisplayRegion, or NULL if no layer is associated (or if the layer was deleted).

GraphicsChannel * get_channel () const
 Returns the GraphicsChannel that this DisplayRegion is ultimately associated with, or NULL if no channel is associated.

GraphicsWindow * get_window () const
 Returns the GraphicsWindow that this DisplayRegion is ultimately associated with, or NULL if no window is associated.

GraphicsPipe * get_pipe () const
 Returns the GraphicsPipe that this DisplayRegion is ultimately associated with, or NULL if no pipe is associated.

void set_camera (const NodePath &camera)
 Sets the camera that is associated with this DisplayRegion.

const NodePath & get_camera () const

void test_ref_count_integrity () const

void copy_clear_settings (const ClearableRegion &copy)

Explicitly increments the reference count.

User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.

This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.

The return value is the new reference count.

int ReferenceCount::unref (   )  const [inline, inherited]
 

Explicitly decrements the reference count.

Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic; plus, we don't have a virtual destructor anyway.) However, see the helper function unref_delete().

User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.

This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.

The return value is the new reference count.
