Detailed Description

IOS OpenGL rendering window.

vtkIOSRenderWindow is a concrete implementation of the abstract class vtkOpenGLRenderWindow. It is only available on iOS. To use this class, build VTK with VTK_USE_IOS turned ON (this is the default). This class can be used by 32 and 64 bit processes, and either in garbage collected or reference counted modes. ARC is not supported. vtkIOSRenderWindow uses Objective-C++, and the OpenGL and IOS APIs. This class's default behaviour is to create an NSWindow and a vtkIOSGLView which are used together to draw all VTK content. If you already have an NSWindow and vtkIOSGLView and you want this class to use them you must call both SetRootWindow() and SetWindowId(), respectively, early on (before WindowInitialize() is executed).

See also: vtkOpenGLRenderWindow vtkIOSGLView

Warning: This header must be in C++ only because it is included by .cxx files. That means no Objective-C may be used. That's why some instance variables are void* instead of what they really should be.

◆ SetWindowId()

void vtkIOSRenderWindow::SetWindowId ( void * )

overridevirtual

Sets the UIView* associated with this vtkRenderWindow.

This class' default behaviour, that is, if you never call this SetWindowId()/SetRootWindow() is to create an NSWindow and a vtkIOSGLView (UIView subclass) which are used together to draw all vtk stuff into. If you already have an NSWindow and UIView and you want this class to use them you must call both SetRootWindow() and SetWindowId(), respectively, early on (before WindowInitialize() is executed). In the case of Java, you should call only SetWindowId().

Reimplemented from vtkRenderWindow.

◆ GetWindowId()

virtual void * vtkIOSRenderWindow::GetWindowId ( )

virtual

Returns the UIView* associated with this vtkRenderWindow.

◆ GetGenericWindowId()

void * vtkIOSRenderWindow::GetGenericWindowId ( )

inlineoverridevirtual

Dummy stubs for vtkWindow API.

Reimplemented from vtkRenderWindow.

Definition at line 326 of file vtkIOSRenderWindow.h.

◆ SetParentId()

void vtkIOSRenderWindow::SetParentId ( void * UIView )

overridevirtual

Set the UIView* for the vtkRenderWindow to be parented within.

The Position and Size of the RenderWindow will set the rectangle of the UIView that the vtkRenderWindow will create within this parent. If you set the WindowId, then this ParentId will be ignored.

Reimplemented from vtkRenderWindow.

◆ GetParentId()

virtual void * vtkIOSRenderWindow::GetParentId ( )

virtual

Get the parent UIView* for this vtkRenderWindow.

This method will return "NULL" if the parent was not set with SetParentId() or SetParentInfo().

◆ GetGenericParentId()

void * vtkIOSRenderWindow::GetGenericParentId ( )

inlineoverridevirtual

Dummy stubs for vtkWindow API.

Reimplemented from vtkRenderWindow.

◆ SetPixelFormat()

void vtkIOSRenderWindow::SetPixelFormat ( void * pixelFormat )

Accessors for the pixel format object (Really an NSOpenGLPixelFormat*).

◆ GetPixelFormat()

void * vtkIOSRenderWindow::GetPixelFormat ( )

Accessors for the pixel format object (Really an NSOpenGLPixelFormat*).

		void *	data,
		int	right = `0`
	)
