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⁽^C++⁾ component is directly connected to the SoText3⁽^C++^|^Java^|^.NET⁾ 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.

C++

#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:

C++

#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;
  }
