*Dear friends. I am born in 1936 and therefor i learn slowly !!!!! HI HI*
*I have made a little program in c using terminal. This program is working
and i must say i am a litle prowed hi hi*
*I have made an emty window with gtk but but How shall i put my input in
this window ???*
*Must say thats difficult for me to understand *
*#include <gtk/gtk.h>*
*int*
*main (int argc,*
* char *argv[])*
*{*
* GtkWidget *window;*
* /* Initialise GTK+ passing to it all command line arguments */*
* gtk_init (&argc, &argv);*
* /* create a new window, set values */*
* window = gtk_window_new (GTK_WINDOW_TOPLEVEL);*
* gtk_window_set_title (GTK_WINDOW (window), "Dette er bare et tomt
vindue");*
* /* set the size of the window */*
* gtk_widget_set_size_request (GTK_WIDGET (window), 200, 200);*
* /* connect the windows "destroy" event */*
* g_signal_connect (G_OBJECT (window), "destroy",*
* G_CALLBACK (gtk_main_quit), NULL); *
* /* set the window as visible */*
* gtk_widget_show (window);*
* /* run the GTK+ main loop */*
* gtk_main ();*
* return 0;*
*}*
*This program here can i compile and i can se an emty window but how do i
make input with my terminal program ?? I am radioamateur and have made this
program for my terminal*
*writing gcc freq.c -o freq i get following skærmbillede fra 2015-03-26
12:19:21.png*
*ole@ole1:~/Skrivebord$ gcc freq.c -o freqole@ole1:~/Skrivebord$ sudo
./freq[sudo] password for ole: Program Started-Port openPortout=
128------Press:"f" - to input frequency,"q" - to exit
program,<space> - to toggle transmitterfInput frequency as 144.000 in Step
25KHz.: 144.625Portout= 153------You se144.000 = portoutput
128 144.625=portoutput 153 146.000=portoutput 20880 channels every 25000
HZ This program want i working with gtk HOWCan i get some hints
???????????????? I will be very very gladI hope somebody can help me Happy
