先看个简单的例子
[cpp] view
plain copy
#include <gtk/gtk.h>
int main(int argc,char *argv[])
{
GtkWidget *window;
GtkWidget *label;
char title[]="test";
char text[]="This is the test.";
gtk_init(&argc, &argv);
window=gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_title(GTK_WINDOW(window), title);
gtk_widget_set_usize(GTK_WINDOW (window),300,150);
label=gtk_label_new(text);
gtk_container_add(GTK_CONTAINER(window), label);
gtk_widget_show(window);
gtk_widget_show(label);
gtk_main();
return 0;
』
其中shell的命令是
[cpp] view
plain copy
gcc -o 3.out 3.c `pkg-config --cflags --libs gtk+-2.0`
其中为什么要加上单引号
pkg-config的作用是警告系统中库的信息
--cflags表示库的编译环境是C 语言
--lib gtk+-2.0需要查找的库是gtk+，版本是2.0
更新了我lib库之后我用的是gtk3.0的
现在先实现calculator中的加法功能
[cpp] view
plain copy
#include <gtk/gtk.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
GtkWidget *window;
GtkWidget *txt1;
GtkWidget *txt2;
GtkWidget *table;
GtkWidget *button;
GtkWidget *label;
void on_clicked(GtkWidget *widget,gpointer data)
{
char a1[10];
char a2[10];
char a3[10];
float a,b,c;
strcpy(a1,gtk_entry_get_text(GTK_ENTRY(txt1)));
strcpy(a2,gtk_entry_get_text(GTK_ENTRY(txt2)));
a = atof(a1);
b = atof(a2);
c = a+b;
gcvt(c,7,a3);
gtk_label_set_text(GTK_LABEL(label),a3);
}
int main(int argc,char **argv)
{
char title[]="my window";
gtk_init(&argc,&argv);
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_title(GTK_WINDOW(window),title);
gtk_window_set_default_size(GTK_WINDOW(window),250,300);
g_signal_connect(G_OBJECT(window),"delete_event",G_CALLBACK(gtk_main_quit),NULL);
txt1 = gtk_entry_new();
gtk_widget_show(txt1);
txt2 = gtk_entry_new();
gtk_widget_show(txt2);
button = gtk_button_new_with_label("OK");
gtk_widget_show(button);
label = gtk_label_new("Result .");
gtk_widget_show(label);
table = gtk_table_new(4,1,FALSE);
gtk_widget_show(table);
gtk_container_add(GTK_CONTAINER(window),table);
gtk_table_attach(GTK_TABLE(table),txt1,0,1,0,1,
(GtkAttachOptions)(GTK_FILL),
(GtkAttachOptions)(0),11,11);
gtk_table_attach(GTK_TABLE(table),txt2,0,1,1,2,
(GtkAttachOptions)(GTK_FILL),
(GtkAttachOptions)(0),11,11);
gtk_table_attach(GTK_TABLE(table),button,0,1,2,3,
(GtkAttachOptions)(GTK_FILL),
(GtkAttachOptions)(0),11,11);
gtk_table_attach(GTK_TABLE(table),label,0,1,3,4,
(GtkAttachOptions)(GTK_FILL),
(GtkAttachOptions)(0),11,11);
g_signal_connect(G_OBJECT(button),"clicked",G_CALLBACK(on_clicked),NULL);
gtk_widget_show_all(window);
gtk_main();
return 0;
}
运行出来的界面是
shell的代码是：
[cpp] view
plain copy
gcc -o calc.out calc.c `pkg-config --cflags --libs gtk+-3.0`
如果还是编译不通过的话有可能是gtk找不到
那可以使用
[cpp] view
plain copy
export LD_LIBRARY_PATH=/usr/lib
把需要的lib库路径加进去
终于写完了，其实应该说是抄完了哇

这个破程序搞了差不多半天时间，就是调不出来，出现的错误是
/tmp/cc7q2YVD.o: In function `input':
calc.c:(.text+0x33): undefined reference to `gtk_entry_append_text'
/tmp/cc7q2YVD.o: In function `dot':

/tmp/cc7q2YVD.o: In function `main':
calc.c:(.text+0x14c8): undefined reference to `gtk_set_locale'
collect2: ld returned 1 exit status
怎么都搞不定，我还看了gtk_entry_append_text这个函数的原型，以及现在的版本说是现在被
gtk_editable_insert_text给代替了，我换成这个函数之后提示还是不对，而且参数的的个数也不对，这个函数要求四个参数，于是就不想折腾了，最后恶心的又更换成个gtk2.0
一次成功，好，不罗嗦。
结果图我就不上传了，就是计算器的一般样子
说说这个程序的缺点吧，缺点非常的多，第一个就是不能简单的连续加减乘除，还有一个就是不能对数据进行简单的判断，还有仅限于简单的加加减减，需要改进
下一步我的目的就是改进这个calculator
在网上查了下GTK，有人已经把我想做的全做了，在此我就不再改进了，直接给出别人的代码供大家和我自己学习

代码的运行结果比我的那个好多了，而且基本上该有的错误规避全有了，代码的出处是http://blog.163.com/qingfeng_0818/blog/static/207603219201243172018226/

』
其中shell的命令是
[cpp] view
plain copy
gcc -o 3.out 3.c `pkg-config --cflags --libs gtk+-2.0`
其中为什么要加上单引号
pkg-config的作用是警告系统中库的信息
--cflags表示库的编译环境是C 语言
--lib gtk+-2.0需要查找的库是gtk+，版本是2.0
更新了我lib库之后我用的是gtk3.0的
现在先实现calculator中的加法功能

}
运行出来的界面是
shell的代码是：
[cpp] view
plain copy
gcc -o calc.out calc.c `pkg-config --cflags --libs gtk+-3.0`
如果还是编译不通过的话有可能是gtk找不到
那可以使用
[cpp] view
plain copy
export LD_LIBRARY_PATH=/usr/lib
把需要的lib库路径加进去
终于写完了，其实应该说是抄完了哇

这个破程序搞了差不多半天时间，就是调不出来，出现的错误是

/tmp/cc7q2YVD.o: In function `dot':

collect2: ld returned 1 exit status
怎么都搞不定，我还看了gtk_entry_append_text这个函数的原型，以及现在的版本说是现在被
gtk_editable_insert_text给代替了，我换成这个函数之后提示还是不对，而且参数的的个数也不对，这个函数要求四个参数，于是就不想折腾了，最后恶心的又更换成个gtk2.0
一次成功，好，不罗嗦。
结果图我就不上传了，就是计算器的一般样子
说说这个程序的缺点吧，缺点非常的多，第一个就是不能简单的连续加减乘除，还有一个就是不能对数据进行简单的判断，还有仅限于简单的加加减减，需要改进
下一步我的目的就是改进这个calculator
在网上查了下GTK，有人已经把我想做的全做了，在此我就不再改进了，直接给出别人的代码供大家和我自己学习
