GLUI Subwindow Template


This article shows you how to create GUI controls for your OpenGL application and organize them into GLUI subwindows. In this article, we will take the source code from the previous article GLUI Window Template, and modify it so that our GLUI controls will be laid out inside two subwindows rather than in a single window. The reason is that having a separate window to contain our GLUI controls could be sometimes annoying for the user, as she or he will have to lose the focus on the OpenGL context window every time she or he wants to do an action. A nice way to avoid this is to place the GLUI controls directly into the GLUT OpenGL window by embedding them into a GLUI subwindow.

This article can be used in the following ways:

  • Learn how to use GLUI subwindows
  • Understand the Viewport concept in OpenGl
  • Use the program as a template for your OpenGL applications that require GUI controls

The image below shows how our controls were laid out into a single GLUI window in the previous article:

The image below shows how our controls will be laid out into two separate subwindows placed on the left and the bottom of our main GLUT window:

GLUI Window Template


This article describes in detail how to create your first GLUI window with some basic controls inside it, and provides you with a template for your OpenGL applications.

When OpenGL applications get more complex, we need something more than a GLUT mouse, keyboard, and\or popup menus to interact with our OpenGL objects drawn on the window. GLUI gives us more flexibility by allowing us to add GUI components to interact with our OpenGL objects, such as buttons, check boxes, radio buttons, spinners, list boxes, lists, trees, file browsers, text fields, text areas, and the special controls: rotation and translation.

This article can be used in the following ways:

  • Learn how to add GUI components to your OpenGL application in a very straight-forward and simple manner, through
    • Documentation
    • Interactive Program that displays to the user how every event is handled and classifies these events into GLUT and GLUI events.
    • Neat and commented Code that reflects the simplicity of the GLUI library
  • Learn some totally new controls in the GLUI library created specifically for graphical manipulation, such as the rotation and translation controls.
  • Use the code as a template for your OpenGL applications.

Make sure you read the GLUT Window Template article as a prerequisite to this article. One important thing to note is that GLUI is a C++ library, which means that your code must be written in files with .cpp extension rather than .C, or otherwise the linker will complain.

GLUT Subwindow Template


This article describes in detail how to set up your first OpenGL GLUT window with multiple sub-windows, and provides you with a template for your OpenGL applications. It can be used in the following ways:

  • Understand GLUT sub-windows
  • Learn new GLUT event handlers
  • Use the code as template if you ever needed a Graphics program with multiple sub-windows

Click below for a screen shot of what the program would look like when its run.

  • Learn GLUT and OpenGL through
    • Interactive Program
    • Documentation
    • Source Code
  • Start your first OpenGL program
  • Use the code as a template for your OpenGL applications

Click below for a screen shot of what the program would look like when its run.

Make sure you at least read the “Running the Program” section of the documentation before you complain about the program not running.
