29.4. Simple Example

Simple 3D Example

Example 29.1. Tutorial01.cxx

This example of DialogViz shows you how to build a simple dialog window and make it interact with your application.

The string you write in the SoDialogEditText component is directly connected to the SoText3 SoText3 SoText3 in the viewer. The slider allows the text color to be changed using a DialogViz auditor.

This tutorial is located in $OIVHOME/src/DialogViz/examples/2D/samples.

#include ...

// Define auditor for dialog and viewer interaction
class ButtonAuditor : public SoDialogPushButtonAuditor
  {
  public:
    void dialogPushButton(SoDialogPushButton *pb) { exit(1); }
  };

class SliderAuditor : public SoDialogRealSliderAuditor
  {
  public:
    void dialogRealSlider(SoDialogRealSlider *rs)
      {
      const float value[][3] = {rs->value.getValue(), 1, 1};
      myColor->rgb.setHSVValues(0, 1, value);
      }
  };

int
main(int, char **argv)
  {

  // Initialize Inventor and DialogViz
  Widget myWindow = SoXt::init(argv[0]);
    SoDialogViz::init();

  // build the viewer scene graph
    SoSeparator *root = new SoSeparator;
    root->ref();

    myColor = new SoBaseColor;
    myColor->rgb.setValue(1,0,0);
    root->addChild(myColor);

    myText = new SoText3;
    root->addChild(myText);

    myViewer = new SoXtExaminerViewer(myWindow);

  // Build the dialog scene graph
    SoTopLevelDialog *myDialog = new SoTopLevelDialog;

    SoDialogEditText *myEdit = new SoDialogEditText;
    myEdit->label = "My text : ";
    myEdit->editText = "my Text";
    myText->string.connectFrom(&myEdit->editText);
    myDialog->addChild(myEdit);

    SoDialogRealSlider *mySlider = new SoDialogRealSlider;
    mySlider->label = "Color : ";
    const SbColor color[8] =
    {
    SbColor(1,0,0), SbColor(1,1,0), SbColor(1,1,0),
      SbColor(0,1,0), SbColor(0,1,1), SbColor(0,0,1),
      SbColor(1,0,1), SbColor(1,0,0)
    };
  mySlider->colors.setValues(0,8, color);
    mySlider->addAuditor(new SliderAuditor());
    myDialog->addChild(mySlider);

    SoDialogPushButton *myButton = new SoDialogPushButton;
    myButton->buttonLabel = "Quit";
    myButton->addAuditor(new ButtonAuditor());
    myDialog->addChild(myButton);

  // Show all
    myDialog->buildDialog(myWindow, FALSE);
    myDialog->show();

    myViewer->setSceneGraph(root);
    myViewer->show();

    SoXt::show(myWindow);
    SoXt::mainLoop();

    return 0;
  }

Simple 3D Example

Example 29.2. Simple 3D menu

This example shows how to build a simple DialogViz interface and load it as ordinary Inventor nodes in a viewer. The dialog box is loaded from an Inventor file.

This tutorial is located in $OIVHOME/src/DialogViz/examples/3D/simple3DMenu.

Here is the Inventor File:

#Inventor V2.1 ascii

TopLevelDialog
  {
  TabDialog
    {
    RowDialog
      {
      label "Choice"
        DialogRadioButtons
        {
        label "radio0"
          items ["item 0",
          "item 1", "item 2"]
        }
      DialogComboBox
        {
        label "Combo Box"
          items ["item 0", "item 1"]
        }
      }
    DialogEditText
      {
      label "Edit Text"
        editText "What a cool demo !"
      }
    RowDialog
      {
      label "Sliders"
        DialogIntegerSlider
        {
        label "Integer :"
          max 10

        }
      DialogSeparator {}
      DialogRealSlider
        {
        label "Real :"
          value 0.5
        }
      }
    }
  DialogCheckBox
    {
    label "Check :"
      onString "box checked"
      offString "box unchecked"
    }
  ColumnDialog
    {
    edgeStyle SHADOW_OUT
      DialogPushButton
      {
      buttonLabel "OK"
      }
    DialogPushButton
      {
      buttonLabel "Cancel"
      }
    }
  }

Here is the program source code:

#include ...

int
main(int, char **argv)
  {

  // Initialize Inventor and DialogViz.
    Widget myWindow = SoXt::init(argv[0]);
    SoDialogViz::init();

    SoSeparator* root = new SoSeparator();
    root->ref();

    SoDialogViz::setSkinsDirectory("texture");

    SoTopLevelDialog* myDialog = (SoTopLevelDialog*)
    SoDialogViz::loadFromFile("./simple3DMenu.iv");
    root->addChild(myDialog);

    SoXtExaminerViewer* myViewer = new SoXtExaminerViewer(myWindow);
    myViewer->setBackgroundColor(SbColor(1,1,1));
    myViewer->setSceneGraph(root);
    myViewer->viewAll();

  // then show.
    myViewer->show();

    SoXt::show(myWindow);
    SoXt::mainLoop();
    SoXt::finish();         // finish Inventor
    return 0;
  }
