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:
