You can view the FLTK documentation in a number of formats on-line: FLTK Developer Documents Git Quick-Start Guide (updated 28 days ago). HTML. This manual describes the Fast Light Tool Kit (“FLTK”) version , a C++ Graphical This manual is organized into the following chapters and appendices. This software and manual are provided under the terms of the GNU Library General I would like to see a chapter which explains how FLTK solves common .

File functions are called when data is ready to read or write, or when an error condition occurs on a file.
FLTK supports normal, embossed, and shadowed labels internally, and more types can be added as desired. Majual functions are called when no user input is present and no timers or files need to be handled – in short, when the application is not doing anything. You can build your Microsoft Windows applications as Console or Desktop applications. For windows you can also provide the command-line arguments to allow users to customize the appearance, size, and position of your windows.
User actions such as mouse movement, button clicks, and keyboard activity generate events that are sent to an application. You can also specify typefaces directly.
FLTK: FLTK Programming Manual
The label string must be in static storage such as a string constant because FLTK does not make a copy of it – it just uses the pointer. But fltk-config can also be used to set the compiler and linker options as variables within a Makefile that can be used to build programs out of multiple source files:.
A “set” method is always of the form “void name type “, and a “get” method tltk always of the form “type name const”. Common Widgets and Attributes [Next]. The resulting program will display the window in Figure manul.
In this example, myGroup would be the current group. More details are available in the Box Types section. This greatly reduces code manuaal and execution time.
LIB libraries to the “Link” settings. However, the “set” methods do not call redraw – you have to call flfk yourself. They can be used to pop up a progress dialog after a certain amount of time or do other things that need to happen at more-or-less regular intervals. The fltk-config script included with FLTK can be used to get the options that are required by your compiler:. All following widgets will automatically be children of this window.
You can quit the program by closing the window or pressing the ESC ape key. As before, the fltk-config script included with FLTK can be used to get the options that are required by your linker:. Finally, you can use the fltk-config script to compile a single source file as a FLTK program:.
In FLTK the top left corner of the window or screen is the origin i. This is usually done using the -I option:.
The labeltype method sets the type of label. The previous section described how to use fltk-config to build a program consisting of a single source file from the command line, and this is very convenient for small test programs. In the case of window widgets, fktk label is used for the label in the title bar. After including the required header files, the program then creates a window. Widgets are commonly ordered into functional groups, which in turn may be grouped again, creating a hierarchy of widgets.
If you want to use the standard C main function as the entry point, FLTK includes a WinMain function that will call your main function for you.
Listing 1 – “hello. A complete list of all label options can be found in the section on Labels and Label Types.
Listing manuap shows a simple “Hello, World! They are most often used to monitor network connections sockets for data-driven displays. In addition the program must include a header file for each FLTK class it uses.
In our “Hello, World! The width and height parameters determine the size of the widget or window mxnual pixels. The x and y parameters determine where the widget or window is placed on the screen. The show method shows the widget or window. Similarly, when linking your application you will need to tell the compiler to use the FLTK library:.
You must also define WIN This chapter teaches you the basics of compiling programs that use FLTK.
