Creating a responsive text box


In this recipe we will learn how to create a text box that responds to the user's keystrokes. It will be active when pressed over by the mouse and inactive when the mouse is released outside the box.

Getting ready

Grab the following files from the recipe Creating an interactive object that responds to the mouse and add them to your project:

  • InteractiveObject.h

  • InteractiveObject.cpp

Create and add the following files to your project:

  • InteractiveTextBox.h

  • InteractiveTextBox.cpp

How to do it…

We will create an InteractiveTextBox class that inherits from InteractiveObject and adds text functionality.

  1. Go to the file InteractiveTextBox.h and add the #pragma once macro and include the necessary files.

    #pragma once
    
    #include "InteractiveObject.h"
    #include "cinder/Text.h"
    #include "cinder/gl/Texture.h"
    #include "cinder/app/KeyEvent.h"
    #include "cinder/app/AppBasic.h"
  2. Now declare the InteractiveTextBox class, making it a subclass of InteractiveObject with the following members and...
