They are most often used to monitor network connections sockets for data-driven displays. Similarly, when linking your application you will need to tell the compiler to use the FLTK library:. In the case of window widgets, the label is used for the label in the title bar.

Documentation

The labeltype method sets the type of label. In this example, myGroup would be the current group. For windows you can also provide the command-line arguments to allow users to customize the appearance, size, and position of your windows. Listing 1 – “hello.

If not specified the label defaults to NULL. You can also specify typefaces directly. But fltk-config can amnual be used to set the compiler and linker options as manial within a Makefile that can be used to build programs out of multiple source files:.

FLTK supports normal, embossed, and shadowed labels internally, and more types can be added as desired. A “set” method is always of the form “void name type “, and a “get” method is always of the form “type name const”. For most widgets the arguments to the constructor are:. 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.

File functions are called when data is ready to read or write, or when an error condition occurs on a file. This is usually done using the -I option:. In addition the program must include a header file for each FLTK class it uses.

Listing 1 shows a simple “Hello, World! Then we create a box with the “Hello, World! LIB libraries to the flgk settings. The show method shows the widget or window. In our “Hello, World! The previous section described how to use manul to build a program consisting of a single source file from the command line, and this is very convenient for small test programs.

Mnaual also supports idle, timer, and file pseudo-events that cause a function to be called when they occur. The application may then ignore the events or respond to the user, typically by redrawing a button in the “down” position, adding the text to an input field, and so forth. You can build your Microsoft Windows applications as Console or Desktop applications. The maximum widget size is typically governed by the underlying window system or hardware.

The fltk-config script included with FLTK can be used to get the options that are mqnual by your compiler:. Newly created groups and their derived widgets implicitly call begin in the constructor, effectively adding all subsequently created widgets to itself until end is called.

Our example program calls the labelfontlabelsizeand labeltype methods. Timer functions are called after a specific amount of time has expired.

Idle callbacks are often used to update a 3D display or do other mahual processing. After including the required header files, the program then creates a window. Finally, you can use the fltk-config script to compile a single source file as a FLTK program:. This greatly reduces code size and execution time.

FLTK applications must periodically check Fl:: 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. Idle 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.

However, the “set” methods do not call redraw – you have to call it yourself. Setting the current group to NULL will stop automatic hierarchies. User actions such as mouse movement, button clicks, and keyboard activity generate events that are sent to an application. As before, the fltk-config script included with FLTK can be used to get the options that are required by your linker:.

Widgets are commonly ordered into functional groups, which in turn may be grouped again, creating a hierarchy of widgets. Common Widgets and Attributes [Next]. A complete list of all label options can be found in the section on Labels and Label Types.
