GLOW feature list

The GLOW 1.0 API provides an extensive set of capabilities for interactive applications using OpenGL. These features fall under the following categories:

• Object-oriented C++ API wrapper for GLUT
• Extensions to GLUT interfaces.
• Powerful, extensible widget system.
• Large widget library.
• Source code compatible across platforms.

Below is a more detailed list of the many features of the GLOW user interface toolkit.

• Object-oriented C++ API wrapper for GLUT
• Create windows, subwindows and menus with a single line of code by constructing objects.
• Operations on windows, subwindows and menus accomplished by method calls. (You do not need to juggle IDs.)
• Events reported directly to objects via virtual methods. (You do not need to keep track of callbacks.)
• Easy reference to fonts and colors via objects.
• Clean deletion of objects by object destructors.
• Typechecked sender-receiver object classes.
• Extensions to GLUT interfaces.
• Component hierarchy for organization and reuse of drawable objects.
• Recursive activation and deactivation of components. Automatically affects event delivery.
• Simulation of modal windows and non-resizable windows.
• Utility components, including a 3D manipulator based on the arcball algorithm.
• Addditional menu manipulation capabilities, including inserting and marking items.
• Automatic computation of additional state, including font metrics, local window positions and menu status.
• Powerful, extensible widget system.
• Widgets may appear in any number of windows and subwindows.
• High-level API creates widgets with a single line of code and automatically lays widgets out.
• Low-level API allows precise control of widget placement and options.
• Predefined message windows and text entry windows for quick creation of alerts and user input dialogs with a single line of code.
• Hierarchical arrangement of widgets using panels and other containers.
• Recursive visibility and activation for widgets.
• Easy management of widget keyboard focus.
• Widget events may be reported via virtual methods or receiver objects.
• Widgets appear and behave the same across platforms.
• Custom widgets may be written and fully integrated into the system.
• Large widget library.
• Push buttons
• Check boxes, 3-state check boxes
• Radio buttons, radio button groups
• Menu buttons, popup menus
• Sliders, including linear and logarithmic scales
• Proportional scroll bars
• Text labels
• Editable text fields, protected text fields (for passwords, etc.)
• Organization panels, separator rules
• Source code compatible across platforms.
• Written in ANSI/ISO compliant C++.
• No platform-specific code. Supports write-once-compile-anywhere development.
