Detailed Description

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.

Member Function Documentation

void WindowHandle::attach_child ( WindowHandle * child ) [virtual]

Called on a parent handle to indicate a child window's intention to attach itself.

Definition at line 81 of file windowHandle.cxx.

void WindowHandle::detach_child ( WindowHandle * child ) [virtual]

Called on a parent handle to indicate a child window's intention to detach itself.

Definition at line 91 of file windowHandle.cxx.

size_t WindowHandle::get_int_handle ( ) const

Returns the OS-specific handle converted to an integer, if this is possible for the particular representation.

Returns 0 if it is not.

Definition at line 53 of file windowHandle.cxx.

WindowHandle::OSHandle * WindowHandle::get_os_handle ( ) const [inline]

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

Definition at line 41 of file windowHandle.I.

Referenced by eglGraphicsWindow::open_window(), and x11GraphicsWindow::open_window().

static void WindowHandle::init_type ( ) [inline, static]

This function is declared non-inline to work around a compiler bug in g++ 2.96.

Making it inline seems to cause problems in the optimizer.

Reimplemented from TypedReferenceCount.

Reimplemented in NativeWindowHandle.

Definition at line 105 of file windowHandle.h.

References TypedReferenceCount::init_type().

void WindowHandle::receive_windows_message	(	unsigned int	msg,
		int	wparam,
		int	lparam
	)		`[virtual]`

Called on a child handle to deliver a keyboard button event generated in the parent window.

Definition at line 115 of file windowHandle.cxx.

void WindowHandle::request_keyboard_focus ( WindowHandle * child ) [virtual]

Called on a parent handle to indicate a child window's wish to receive keyboard button events.

Definition at line 104 of file windowHandle.cxx.

void WindowHandle::send_windows_message	(	unsigned int	msg,
		int	wparam,
		int	lparam
	)

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.

Definition at line 39 of file windowHandle.cxx.

void WindowHandle::set_os_handle ( OSHandle * os_handle ) [inline]

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

Definition at line 52 of file windowHandle.I.
