You select widgets by clicking on their names, which highlights them (you can also select widgets from any displayed window). Widgets are shown in the browser by either their name (such as 'main_panel' in the example), or by their type and label (such as 'Button 'the green''). Tab groups provide the well-known file-card tab interface. Plain groups are for layout, navigation, and resize purposes. Each of these produces an instance of class Fl_Window.īelow that are either widgets (subclasses of Fl_Widget) or groups of widgets (including other groups). The second level of the hierarchy contains the windows. Calling the function or instantiating the class will create all of the child widgets. Each of these will produce a single C++ public function or class in the output. The top level of the hierarchy is composed of functions and classes. The leftmost widgets are the parents, and all the widgets listed below them are their children. You can open and close a level by clicking the 'triangle' at the left of a widget. fl file being edited is shown in the window title. The main window shows a menu bar and a scrolling browser of all the defined widgets.

The following sections describe each of the windows in FLUID. You can include the CubeViewUI.h (or whatever extension you prefer) as you would any other C++ class. Select that option and set your desired file extensions and you are in business. Open the preferences dialog from Edit->Preferences.Īt the bottom of the preferences dialog box is the key: 'Include Header from Code'. There is one last trick to ensure this all works. Now that we have completely defined the CubeViewUI, we have to generate the code.

#FLUID BROWSER 1.5 CODE#

If you need to add code to initialize a class, for example setting initial values of the horizontal and vertical angles in the CubeView, you can simply highlight the constructor and select New->Code->Code. Enter the method's code in the code window. Once the new method has been added, highlight its name and select New->Code->Code. Here is the CubeView class definition, as given by its header file 'test/CubeView.h': You can safely skip this section as long as you realize that CubeView is a sublass of Fl_Gl_Window and will respond to calls from CubeViewUI, generated by FLUID.

It has methods for setting the zoom, the x and y pan, and the rotation angle about the x and y axes. The CubeView class is a subclass of Fl_Gl_Window. Subclass an Fl_Gl_Window to suit your purposes.Use FLUID to set callbacks member functions of a custom widget classes.Use FLUID to create a complete user interface class, including constructor and any member functions necessary.CubeViewUI manages CubeView using callbacks from the various sliders and rollers to manipulate the viewing angle and zoom of CubeView.Īt the completion of this tutorial you will (hopefully) understand how to: The central display of the cube is a separate subclass of Fl_Gl_Window called CubeView. The window is of class CubeViewUI, and is completely generated by FLUID, including class member functions. Widgets may either call a named callback function that you write in another source file, or you can supply a small piece of C++ source and FLUID will write a private callback function into the. An unnamed widget has a blank name and no pointer is stored. This can be used to get the widgets into structures. In this case FLUID assigns a pointer to the widget to the name, but does not attempt to declare it. A complex named object has punctuation such as '.' or '->' or any other symbols in its name. In this case FLUID defines a global variable or class member that will point at the widget after the function defining it is called. A named widget has a legal C++ variable identifier as its name (i.e. Widgets created by FLUID are either 'named', 'complex named' or 'unnamed'. Each function defines one or more FLTK windows, and all the widgets that go inside those windows. Normally the FLUID file defines one or more functions or classes which output C++ code. cxx file so it still appears to be a single source file. Most programs are more complex than this, so you write other. cxx file a single source file to compile.

FLUID also supports localization ( Internationalization) of label strings using message files and the GNU gettext or POSIX catgets interfaces.Ī simple program can be made by putting all your code (including a main() function) into the. cxx file defines all the objects from the. These files are text, and you can (with care) edit them in a text editor, perhaps to get some special effects.įLUID can 'compile' the. The Fast Light User Interface Designer, or FLUID, is a graphical editor that is used to produce FLTK source code.
