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 ( int  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.
