Detailed Description

Abstract base class for all Open Inventor Qt components.

Abstract base class from which all Open Inventor Qt components are derived. This class provides a basic C++ protocol for building and displaying Qt components. Components are used to encapsulate some function or task into a reusable package in the form of a Qt widget handle that can be used in any Open Inventor Qt program. See the Example section on how to build and use SoQtComponents.

EXAMPLE

SoQtExaminerViewer

#include <Inventor/Qt/SoQt.h>
#include <Inventor/nodes/SoCone.h>
#include <Inventor/Qt/viewers/SoQtExaminerViewer.h>

void main(int, char* *argv)

// Initialize Inventor and Qt, which must be done
// before any Inventor calls are made.

QWidget* myWidget = SoQt::init(argv[0]);

// Create the viewer in the toplevel window
// and set some scene to display.

SoQtExaminerViewer *myViewer = new SoQtExaminerViewer(myWidget);
myViewer->setSceneGraph( new SoCone() );

// Map window on screen.

myViewer->show();
SoQt::show(myWidget); // calls Show()

// Loop forever

SoQt::mainLoop();

Member Typedef Documentation

◆ SoQtComponentCB

typedef void SoQtComponentCB(void *userData, SoQtComponent *comp)

Definition at line 47 of file SoQtComponent.h.

Member Function Documentation

◆ getClassName()

SbString SoQtComponent::getClassName ( ) const

inline

Returns the class name.

The class name is predefined by each component.

Definition at line 397 of file SoQtComponent.h.

◆ getComponent()

static SoQtComponent * SoQtComponent::getComponent ( QWidget * widget )

static

Returns the SoQtComponent for this widget handle.

If the widget handle does not match that of any Open Inventor component, then NULL is returned.

◆ getDisplay()

SbGlContextHelper::Display SoQtComponent::getDisplay ( )

inline

On UNIX, returns the X display associated with this components widget.

Definition at line 379 of file SoQtComponent.h.

◆ getIconTitle()

const QString SoQtComponent::getIconTitle ( ) const

inline

Included for portability only.

Definition at line 391 of file SoQtComponent.h.

◆ getParentWidget()

QWidget * SoQtComponent::getParentWidget ( ) const

inline

Returns the parent widget handle.

Definition at line 145 of file SoQtComponent.h.

◆ getShellWidget()

QWidget * SoQtComponent::getShellWidget ( ) const

inline

Returns the topLevelShell widget handle (NULL if the topLevelShell hasn't been created by this component).

Definition at line 140 of file SoQtComponent.h.

◆ getSize()

SbVec2s SoQtComponent::getSize ( )

Convenience routine on the widget handle.

◆ getTitle()

const QString SoQtComponent::getTitle ( ) const

inline

Gets window title.

Definition at line 385 of file SoQtComponent.h.

◆ getWidget()

virtual QWidget * SoQtComponent::getWidget ( ) const

inlinevirtual

This returns the base widget handle for this component.

Definition at line 127 of file SoQtComponent.h.

◆ getWidgetName()

SbString SoQtComponent::getWidgetName ( ) const

inline

Returns the widget handle name.

The widget handle name is passed to the build method.

Definition at line 403 of file SoQtComponent.h.

◆ hide()

virtual void SoQtComponent::hide ( )

virtual

This hides the component.

Reimplemented in SoQtColorEditor, SoQtDirectionalLightEditor, SoQtGLWidget, SoQtMaterialEditor, SoQtMaterialPalette, and SoQtFullViewer.

◆ isFullScreen()

SbBool SoQtComponent::isFullScreen ( void ) const

Queries if the viewer is in fullscreen mode.

◆ isFullScreenEnable()

SbBool SoQtComponent::isFullScreenEnable ( void ) const

Queries if it is possible to put the viewer in fullscreen mode.

◆ isTopLevelShell()

SbBool SoQtComponent::isTopLevelShell ( ) const

inline

Returns TRUE if this component is a top level shell component (has its own window).

Subclasses may use this to decide if they are allowed to resize themselves.

Definition at line 134 of file SoQtComponent.h.

◆ isVisible()

SbBool SoQtComponent::isVisible ( )

Returns TRUE if this component is mapped onto the screen.

For a component to be visible, its widget and the shell containing this widget must be mapped (which is FALSE when the component is iconified).

◆ setFullScreen()

virtual SbBool SoQtComponent::setFullScreen ( const SbBool enable )

virtual

Switches the viewer into (or out of) fullscreen mode.

This works fine on Windows, but has certain problems under the X Window System. For details, see the Qt documentation for QWidget::showFullScreen.

◆ setFullScreenEnable()

void SoQtComponent::setFullScreenEnable ( const SbBool enable )

Enables/disables fullscreen mode.

If fullscreen mode is disabled, it is not possible to activate fullscreen mode with the right mouse button popup menu.

◆ setIconTitle()

void SoQtComponent::setIconTitle ( const QString & newIconTitle )

Included for portability only.

◆ setSize()

void SoQtComponent::setSize ( const SbVec2s & size )

Convenience routine on the widget handle.

◆ setTitle() [1/3]

void SoQtComponent::setTitle ( const char * newTitle )

Sets window title.

The window title can be set for topLevelShell components or components which are directly under a shell window handle (i.e. components which have their own window).

◆ setTitle() [2/3]

void SoQtComponent::setTitle ( const QString & newTitle )

Sets window title.

The window title can be set for topLevelShell components or components which are directly under a shell window handle (i.e. components which have their own window).

◆ setTitle() [3/3]

void SoQtComponent::setTitle ( const SbString & newTitle )

Sets window title.

The window title can be set for topLevelShell components or components which are directly under a shell window handle (i.e. components which have their own window).

◆ setWindowCloseCallback()

void SoQtComponent::setWindowCloseCallback	(	SoQtComponentCB *	func,
		void *	data = `NULL`
	)

inline

Sets which callback to call when the user closes this component (double click in the upper left corner) - by default hide() is called on this component, unless a callback is set to something other than NULL.

A pointer to this class will be passed as the callback data.

Note: this callback is supplied because the user may wish to delete this component when it is closed.

Definition at line 266 of file SoQtComponent.h.

◆ show()

virtual void SoQtComponent::show ( )

virtual

This shows the component.

Reimplemented in SoQtColorEditor, SoQtDirectionalLightEditor, SoQtGLWidget, SoQtMaterialEditor, and SoQtMaterialPalette.
