SoXtSliderSetBase(3IV)()												  SoXtSliderSetBase(3IV)()

NAME
SoXtSliderSetBase -- abstract base class for Motif-only slider components INHERITS FROM
SoXtComponent > SoXtSliderSetBase SYNOPSIS
#include <Inventor/Xt/SoXtSliderSetBase.h> Methods from class SoXtSliderSetBase: virtual void setNode(SoNode *newNode) SoNode * getNode() const Methods from class SoXtComponent: virtual void show() virtual void hide() SbBool isVisible() Widget getWidget() const SbBool isTopLevelShell() const Widget getShellWidget() const Widget getParentWidget() const void setSize(const SbVec2s &size) SbVec2s getSize() Display * getDisplay() void setTitle(const char *newTitle) const char * getTitle() const void setIconTitle(const char *newIconTitle) const char * getIconTitle() const void setWindowCloseCallback(SoXtComponentCB *func, void *data = NULL) static SoXtComponent * getComponent(Widget w) const char * getWidgetName() const const char * getClassName() const DESCRIPTION
This class is used as a base class for all editors which use Motif sliders to edit fields in an Inventor scene graph node. This class is not meant to be instanced by programmers who want to use an editor in a program. It should only be used as a base class when designing new editors. SoXtSliderSetBase is derived from SoXtComponent, but adds three concepts. First, there is a node to edit. Second, there are subcomponents. When an SoXtSliderSetBase is shown or hidden, so are its subcomponents. (As an example, an SoXtTransformSliderSet is composed of many sub- components). Third, an SoXtSliderSetBase has a layout size, which is used to lay out the subcomponents. METHODS
virtual void setNode(SoNode *newNode) Sets a new node as the node to be modified by this editor component. SoNode * getNode() const Returns a pointer to the node currently being modified by this editor component. SEE ALSO
SoXtComponent, SoXtSliderSet SoXtSliderSetBase(3IV)()
