I don't have time at present to write a full, coherent HOWTO. What you'll find here are various ideas, tips and examples in a fairly raw state. Since some elements below may date fairly quickly, I should say that I'm writing this in early October, 2004. Cross-compiler and binutils Your first requirement is a cross-compiler and an appropriate set of binutils (as, ld and friends). Now you need to decide on a location for your cross system. . #! #! Or something like that. Win32 API #! #! GUI Building With GTK. While developing the GIMP (GNU Image Manipulation Program) a few years back, Spencer Kimball and Peter Mattis decided that it might be fun to write a user interface toolkit to go along with it.
And so they created GTK+ (the GIMP Toolkit) -- a library of "widgets" that makes it easier for developers to build GUI-based application. A widget is one of the various components of a graphical application; a toolbar, for example. The widgets provide programmers with pre-built dialog boxes, windows, menu bars and other GUI components. Having a pre-built foundation for these user interface components greatly speeds development of GUI applications and also enables applications built with those widgets to share a common "look and feel". While developing the GIMP (GNU Image Manipulation Program) a few years back, Spencer Kimball and Peter Mattis decided that it might be fun to write a user interface toolkit to go along with it. Container Widgets Some widgets can act as containers for other widgets. First programs in GTK+ HomeContents In this part of the GTK+ programming tutorial, we will create our first programs in GTK+ Simple example We start with a very simple example.
We will show a basic window. #include <gtk/gtk.h> int main( int argc, char *argv[]) { GtkWidget *window; gtk_init(&argc, &argv); window = gtk_window_new(GTK_WINDOW_TOPLEVEL); gtk_widget_show(window); gtk_main(); return 0; } This example will show a basic window on screen. gcc -o simple simple.c `pkg-config --libs --cflags gtk+-2.0` This is how we compile the example. gtk_init(&argc, &argv); Here we initiate the GTK+ library. window = gtk_window_new(GTK_WINDOW_TOPLEVEL); We create a GtkWindow widget.
Gtk_widget_show(window); After we have created a widget, we must show it. gtk_main(); This code enters the GTK+ main loop. Figure: Simple Centering the window If we do not position the window ourselves, the window manager will position it for us. In our example, we center the window, set a title and size for the window. This code centers the window.
