 Constructs a new WindowHandle with an int value, which is understood to be either an HWND or a Window, cast to int. This method exists for the convenience of Python, which likes to deal with ints; C++ code should use one of the more specific make_x11() or make_win32() methods instead. More...

int getTypeIndex ()
 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(). More...

- Public Member Functions inherited from ReferenceCount
int getRefCount ()
 Returns the current reference count. More...
 
 ref ()
 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. More...
 
bool testRefCountIntegrity ()
 Does some easy checks to make sure that the reference count isn't completely bogus. Returns true if ok, false otherwise. More...
 
bool testRefCountNonzero ()
 Does some easy checks to make sure that the reference count isn't zero, or completely bogus. Returns true if ok, false otherwise. More...
 
bool unref ()
 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(). More...
 

Detailed Description

This subclass of WindowHandle exists to allow simple creation of a WindowHandle of the appropriate type to the current OS.

This class exists for name scoping only. Don't use the constructor directly; use one of the make_* methods.

Member Function Documentation

◆ getClassType()

static TypeHandle getClassType ( )
static

◆ makeInt()

static WindowHandle makeInt ( size_t  window)
static

Constructs a new WindowHandle with an int value, which is understood to be either an HWND or a Window, cast to int. This method exists for the convenience of Python, which likes to deal with ints; C++ code should use one of the more specific make_x11() or make_win32() methods instead.

◆ makeSubprocess()

static WindowHandle makeSubprocess ( const Filename  filename)
static

Constructs a new WindowHandle that references a SubprocessWindowBuffer read in another process, with the named pipe filename that it uses for communication.

This is (at present, and maybe always) useful only on the OS X platform, where parenting child windows is particularly problematic.
