NAME

SoXtDevice — abstract base class device for use with the SoXtRenderArea

INHERITS FROM

SoXtDevice

SYNOPSIS

#include <Inventor/Xt/devices/SoXtDevice.h>

Methods from class SoXtDevice:

virtual void enable(Widget w, XtEventHandler f, XtPointer data, Window win = NULL)

virtual void disable(Widget w, XtEventHandler f, XtPointer data)

virtual const SoEvent * translateEvent(XAnyEvent *xevent)

void setWindowSize(const SbVec2s &size)

const SbVec2s & getWindowSize() const

DESCRIPTION

This is the abstract base class for devices in the Inventor Xt component and utility library. When a device is registered with an SoXtRenderArea, the device is able to generate events in the render area window.

METHODS

virtual void enable(Widget w, XtEventHandler f, XtPointer data, Window win = NULL)

virtual void disable(Widget w, XtEventHandler f, XtPointer data)

Enable and disable the device for the passed widget. When enabled, the callback function f will be invoked when events occur in the widget. data is the clientData which will be passed.

virtual const SoEvent * translateEvent(XAnyEvent *xevent)

This attempts to convert the passed X event into an SoEvent. If the event was not generated by this device, then NULL is returned.

void setWindowSize(const SbVec2s &size)

const SbVec2s & getWindowSize() const

Set and get the window size of the widget this device is registered for. This allows the device to correctly convert position information from X window coordinates (origin at top left) to Inventor window coordinates (origin at bottom left). (SoXtRenderArea will automatically call this method for each device registered on it whenever the window size changes.)
