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

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¶

static getClassType() → TypeHandle¶

Return type: TypeHandle

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¶

__init__(copy: WindowHandle) → None¶

__init__(os_handle: OSHandle) → None¶

static getClassType() → TypeHandle¶

Return type: TypeHandle

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

getOsHandle() → OSHandle¶

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

Return type: OSHandle

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

output(out: ostream) → None¶

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.

setOsHandle(os_handle: OSHandle) → None¶: Changes the OS-specific handle stored internally to the WindowHandle wrapper.
