Static Public Member Functions | |
static TypedWritableReferenceCount | decodeFromBamStream (string data, BamReader reader) |
Reads the string created by a previous call to encode_to_bam_stream(), and extracts and returns the single object on that string. | |
static TypedWritableReferenceCount | decodeFromBamStream (string data) |
Reads the string created by a previous call to encode_to_bam_stream(), and extracts and returns the single object on that string. | |
static TypeHandle | getClassType () |
This is the class that defines a rectangular region on the screen for the MouseWatcher.
enum SuppressFlags |

) |
MouseWatcherRegion | ( | string | name, |
float | left, | ||
float | right, | ||
float | bottom, | ||

) |
clearName | ( | ) | [inherited] |
Resets the Namable's name to empty.
Reimplemented in AsyncTask.
static TypedWritableReferenceCount decodeFromBamStream | ( | string | data, |
BamReader | reader | ||
) | [static, inherited] |
Reads the string created by a previous call to encode_to_bam_stream(), and extracts and returns the single object on that string.
Returns NULL on error.
This method is intended to replace decode_raw_from_bam_stream() when you know the stream in question returns an object of type TypedWritableReferenceCount, allowing for easier reference count management. Note that the caller is still responsible for maintaining the reference count on the return value.
static TypedWritableReferenceCount decodeFromBamStream | ( | string | data | ) | [static, inherited] |
Reads the string created by a previous call to encode_to_bam_stream(), and extracts and returns the single object on that string.
Returns NULL on error.

string encodeToBamStream | ( | ) | [inherited] |
Converts the TypedWritable object into a single stream of data using a BamWriter, and returns that data as a string string.
Returns empty string on failure.
This is a convenience method particularly useful for cases when you are only serializing a single object. If you have many objects to process, it is more efficient to use the same BamWriter to serialize all of them together.
bool encodeToBamStream | ( | basic_stringchar | data, |
BamWriter | writer | ||
) | [inherited] |
Converts the TypedWritable object into a single stream of data using a BamWriter, and stores that data in the indicated string.
Returns true on success, false on failure.

bool getActive | ( | ) |
Returns whether the region is active or not.
See set_active().
float getArea | ( | ) |
Returns the area of the rectangular region.
UpdateSeq getBamModified | ( | ) | [inherited] |
Returns the current bam_modified counter.
This counter is normally incremented automatically whenever the object is modified.
static TypeHandle getClassType | ( | ) | [static] |
Reimplemented from Namable.
Reimplemented in PGMouseWatcherBackground.
VBase4 const getFrame | ( | ) |
bool getKeyboard | ( | ) |
Returns whether the region is interested in global keyboard events; see set_keyboard().
string getName | ( | ) | [inherited] |
Reimplemented in DynamicTextFont.
int getRefCount | ( | ) | [inherited] |
Returns the current reference count.
int getSort | ( | ) |
Returns the current sorting order of this region.
See set_sort().
int getSuppressFlags | ( | ) |
Returns the current suppress_flags.
See set_suppress_flags().
TypeHandle getType | ( | ) | [inherited] |
Reimplemented in AnimChannelBase.
int getTypeIndex | ( | ) | [inherited] |
Returns the internal index number associated with this object's TypeHandle, a unique number for each different type.
This is equivalent to get_type().get_index().
bool hasName | ( | ) | [inherited] |
Returns true if the Namable has a nonempty name set, false if the name is empty.
bool isExactType | ( | TypeHandle | handle | ) | [inherited] |
Returns true if the current object is the indicated type exactly.
bool isOfType | ( | TypeHandle | handle | ) | [inherited] |
Returns true if the current object is or derives from the indicated type.
markBamModified | ( | ) | [inherited] |
Increments the bam_modified counter, so that this object will be invalidated and retransmitted on any open bam streams.
This should normally not need to be called by user code; it should be called internally when the object has been changed in a way that legitimately requires its retransmission to any connected clients.
output | ( | ostream | out | ) |
PyObject reduce | ( | PyObject | self | ) | [inherited] |
This special Python method is implement to provide support for the pickle module.
This hooks into the native pickle and cPickle modules, but it cannot properly handle self-referential BAM objects.
PyObject reducePersist | ( | PyObject | self, |
PyObject | pickler | ||
) | [inherited] |
This special Python method is implement to provide support for the pickle module.
This is similar to __reduce__, but it provides additional support for the missing persistent-state object needed to properly support self-referential BAM objects written to the pickle stream. This hooks into the pickle and cPickle modules implemented in direct/src/stdpy.
ref | ( | ) | [inherited] |
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.
setActive | ( | bool | active | ) |
Sets whether the region is active or not.
If it is not active, the MouseWatcher will never consider the mouse to be over the region. The region might still receive keypress events if its set_keyboard() flag is true.
setFrame | ( | float | left, |
float | right, | ||
float | bottom, | ||
float | top | ||
) |
setFrame | ( | VBase4 const | frame | ) |
setKeyboard | ( | bool | keyboard | ) |
Sets whether the region is interested in global keyboard events.
If this is true, then any keyboard button events will be passed to press() and release() regardless of the position of the mouse onscreen; otherwise, these events will only be passed if the mouse is over the region.
setSort | ( | int | sort | ) |
Changes the sorting order of this particular region.
The sorting order is used to resolve conflicts in the case of overlapping region; the region with the highest sort value will be preferred, and between regions of the same sort value, the smallest region will be preferred. The default sorting order, if none is explicitly specified, is 0.
setSuppressFlags | ( | int | suppress_flags | ) |
Sets which events are suppressed when the mouse is over the region.
This is the union of zero or more various SF_* values. Normally, this is 0, indicating that no events are suppressed.
If you set this to a non-zero value, for instance SF_mouse_position, then the mouse position will not be sent along the data graph when the mouse is over this particular region.
bool testRefCountIntegrity | ( | ) | [inherited] |
Does some easy checks to make sure that the reference count isn't completely bogus.
Returns true if ok, false otherwise.
Reimplemented in NodeReferenceCount, CachedTypedWritableReferenceCount, and NodeCachedReferenceCount.
bool testRefCountNonzero | ( | ) | [inherited] |
Does some easy checks to make sure that the reference count isn't zero, or completely bogus.
Returns true if ok, false otherwise.
bool unref | ( | ) | [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.) 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 true if the new reference count is nonzero, false if it is zero.
Reimplemented in GeomVertexArrayFormat, and GeomVertexFormat.
