The program starts by loading the required modules core
, base
, display
and
gui
. The keyword _main_
states that this file contains the main program,
then we build a tree of components.
The program appends three children to the root
component: a
Frame, an Exit component, and what we call a Binding (symbolized by the arrow) that connects
the built-in close
frame's child to the quit
component.
Compile this program with:
smalac main.sma
This will generate a main.cpp
file that can be compiled with:
gcc -I<path-to-djnn-header> main.cpp -o app -L<path-to-djnn-libs> -ldjnn-core -ldjnn-base -ldjnn-display -ldjnn-gui
If you have downloaded the Smala sources you will find in cookbook/stand_alone
the skeleton of a Smala application. Change the paths in the provided Makefile to fit with your own installation.
