linux嵌入式应用开发- ubuntu eclipse/C gtk用户界面编程

环境：ubuntu, eclipse ,c gtk

linux 环境下编程主要有两种方式:GTK  和QT

1，安装gtk 环境

sudo apt-get install build-essential sudo apt-get install gnome-core-develsudo apt-get install pkg-config sudo apt-get install devhelp sudo apt-get install libglib2.0-doc libgtk2.0-doc

2，编写代码

#include /*定义回调函数hello，点击按钮时被系统自动调用*/void main_btn_clicked(GtkWidget *widget,gpointer *data){g_print("button clicked and data = %s\n",(char *)data);voice_start(0);}/*定义回调函数destroy，关闭窗口时被系统自动调用*/void main_destroy(GtkWidget *widget,gpointer *data){gtk_main_quit();}int main_init_GUI(int value,char* argv[]){/*定义指向控件的指针*/GtkWidget *window;GtkWidget *fixed_container;GtkWidget *complete_btn;GtkWidget *scroll_bar;GtkWidget *text_view;GtkTextItertext_iter;/*初始化图形显示环境*/gtk_init(&value,&argv);/*创建窗口，并设置当关闭窗口时，要执行的回调函数*/window = gtk_window_new(GTK_WINDOW_TOPLEVEL);g_signal_connect(GTK_OBJECT(window),"destroy",GTK_SIGNAL_FUNC(main_destroy),NULL);gtk_container_border_width(GTK_CONTAINER(window),0);/*设置窗口的属性*/gtk_window_set_title(GTK_WINDOW(window),"demo");gtk_widget_set_size_request(window,800,480);//set window sizegtk_window_set_position(GTK_WINDOW(window),GTK_WIN_POS_CENTER);//set window  position/*create box container*/fixed_container=gtk_fixed_new();//gtk_vbox_new(FALSE,0);gtk_widget_set_usize(fixed_container,800,480);//set window size/*创建按钮，并设置当点击按钮时，要执行的回调函数*/complete_btn = gtk_button_new_with_label("complete");g_signal_connect(GTK_OBJECT(complete_btn),"clicked",GTK_SIGNAL_FUNC(main_btn_clicked),"complete_btn");gtk_widget_set_size_request(complete_btn,180,80);//set window sizegtk_fixed_put(GTK_FIXED(fixed_container),complete_btn,280,360);scroll_bar=gtk_scrolled_window_new(NULL,NULL);gtk_scrolled_window_set_policy(GTK_SCROLLED_WINDOW(scroll_bar),GTK_POLICY_AUTOMATIC,GTK_POLICY_ALWAYS);gtk_widget_set_size_request(scroll_bar,600,280);//set window sizegtk_fixed_put(GTK_FIXED(fixed_container),scroll_bar,100,50);gtk_widget_show(scroll_bar);/*创建text view*/text_view = gtk_text_view_new();gtk_scrolled_window_add_with_viewport(GTK_SCROLLED_WINDOW(scroll_bar),text_view);//gtk_container_add(GTK_CONTAINER(scroll_bar),text_view);text_buffer=gtk_text_view_get_buffer(GTK_TEXT_VIEW(text_view));gtk_text_buffer_get_iter_at_offset(text_buffer,&text_iter,0);gtk_text_buffer_insert(text_buffer,&text_iter,"",-1);gtk_container_add(GTK_CONTAINER(window),fixed_container);voice_init_engine(&callback_result,&callback_status);/*regeist the callback*/gtk_widget_show_all(window);/*进入消息处理循环*/gtk_main();return 0;}

3，设置eclipse 环境

a, properties ->c/c++build/->setting->gcc c compiler->include

include path(-i) 添加   /usr/include/gtk-2.0      /usr/include/glib-2.0

b, properties ->c/c++build/->setting->gcc c compiler->miscellaneous 

Other flags 中添加  ·pkg-config --cflags gtk+-2.0·

c, properties ->c/c++build/->setting->GCC clinker ->miscellaneous

linker flags 后面添加 ·pkg-config --libs gtk+-2.0·
