=== Download Software ===
Get the latest version of Bloodshed Dev-C++ with Mingw/GCC from (~9 MB): 
http://www.bloodshed.net/dev/devcpp.html 
or v-4.9.9.2 directly from: 
http://prdownloads.sourceforge.net/dev-cpp/devcpp-4.9.9.2_setup.exe 

Install in an appropriate place.

After starting the program the first thing you need to do is to download the FLTK library. Go to “Tools->Check for updates / packages”.

Select devpak server “devpaks.org Community Devpaks” click “Check for updates” and check the fltk version 1.1.7 and click “Download selected” and continue with the installation of the library. 1.1.7 is a stable version of the FLTK library. FLTK2 is still a beta release.

=== Start a new FLTK project ===

Start Bloodshed Dev-C++ and start a new project “File->new-> project”. Choose “Empty Project” and give the project a name.

Add a new source file to the project “File->new->Source File”. Save file as main.cpp.

In order to setup the FLTK library for the project go to “Project->Project options” and add the following under the Parameters tab:

<pre>
Compiler: -DWIN32 -mms-bitfields
Linker: -lfltk -lole32 -luuid -lcomctl32 -lwsock32 –lm
</pre>

=== Develop code ===

Create a new source file and write the following code:

<pre>
#include !<FL/Fl.H>
#include \<FL/Fl_Window.H>

int main (int argc , int **argv)
{
Fl_Window win(400,200,"Test"); //win(width, height,name)
win.show(); // show window
return(Fl::run()); //fltk application loop

}
</pre>

Save and press F9 (Compile & Run) and a simple window will be created.

===Create a simple window with a button===

<pre>
#include <FL/Fl.H>
#include <FL/Fl_Window.H>
#include <FL/Fl_Button.H>

void but_cb(Fl_Widget* w, void*){
Fl_Button *b= (Fl_Button*)w;
if (b->label() == "Off") {
b->label("On");
}else{
b->label("Off");
}
}

int main (int argc , int **argv)
{
Fl_Window win(400,200,"Test"); //win(width, height,name)
Fl_Button but(100,50,70,30,"On");

win.show();
// show window
but.callback(but_cb);

return(Fl::run()); //fltk application loop
}

</pre>
