panda3d.core.WindowHandle

from panda3d.core import WindowHandle
class WindowHandle

Bases: TypedReferenceCount

This object represents a window on the desktop, not necessarily a Panda window. This structure can be assigned to a WindowProperties to indicate a parent window.

It also has callbacks so the Panda window can communicate with its parent window, which is particularly important when running embedded in a browser.

To create a WindowHandle, you would usually call one of the NativeWindowHandle::make_*() methods, depending on the kind of native window handle object you already have.

Inheritance diagram

Inheritance diagram of WindowHandle

__init__(copy: WindowHandle) → None
__init__(os_handle: OSHandle) → None
getOsHandle() → OSHandle

Returns the OS-specific handle stored internally to the WindowHandle wrapper.

Return type

OSHandle

setOsHandle(os_handle: OSHandle) → None

Changes the OS-specific handle stored internally to the WindowHandle wrapper.

sendWindowsMessage(msg: int, wparam: int, lparam: int) → None

Call this method on a parent WindowHandle to deliver a Windows message to the current child window, if any. This is used in the web plugin system to deliver button events detected directly by the browser system into Panda, which is particularly necessary on Vista.

getIntHandle() → size_t

Returns the OS-specific handle converted to an integer, if this is possible for the particular representation. Returns 0 if it is not.

Return type

size_t

output(out: ostream) → None
static getClassType() → TypeHandle

property os_handle
Getter

Returns the OS-specific handle stored internally to the WindowHandle wrapper.

Setter

Changes the OS-specific handle stored internally to the WindowHandle wrapper.

Return type

OSHandle

class OSHandle

Bases: TypedReferenceCount

This internal pointer within WindowHandle stores the actual OS-specific window handle type, whatever type that is. It is subclassed for each OS.

__init__(param0: OSHandle) → None
getIntHandle() → size_t

Returns the OS-specific handle converted to an integer, if this is possible for the particular representation. Returns 0 if it is not.
