用了Linux 突然间想写点C的程序,大家都说GTK 好用,所以就拿GTK 作实验。
第一步:搭建开发环境
1.gcc和java,这个应该不难,一般的发行版里都有gcc,Java可以到www.sun.com下载,安装配置,google 一下到处都是。
2.到www.netbeans.org 下载netbeans IDE ,有专门的C++ 版。
3.Gtk+可以直接安装libgtk2.0-dev软件包,也可以从http://www.gtk.org/下载源码,编译安装。可能需要其他依赖的软件包如下:
- pkg-config
- GNU make
- JPEG, PNG and TIFF image libraries
- FreeType
- fontconfig
- GNU libiconv library
- GNU gettext
- GLib
- Pango
- ATK
- GTK+
第二步:配置NetBeans
如果前三项都做完了,那么我们可以开始配置netbeans 了
1.启动netbeans ,打开工具->选项->C/C++
还有需要在项目属性里添加如下路径:
在代码辅助里面添加GTK2.0的头文件位置:
/usr/include/gtk-2.0
这是为了写代码的时候方便提示例如:
在没有添加之前需要这样写:
#include<gtk-2.0/gtk/gtk.h>
添加之后就可以这样写:
#include<gtk/gtk.h>
接着我们就可以写代码了,这里我copy了一下网上的代码:
#include<gtk/gtk.h>
/* This is a callback function. The data arguments are ignored
* in this example. More on callbacks below. */
static void hello( GtkWidget *widget,
gpointer data )
{
g_print ("Hello World\n");
}
static gboolean delete_event( GtkWidget *widget,
GdkEvent *event,
gpointer data )
{
/* If you return FALSE in the "delete_event" signal handler,
* GTK will emit the "destroy" signal. Returning TRUE means
* you don't want the window to be destroyed.
* This is useful for popping up 'are you sure you want to quit?'
* type dialogs. */
g_print ("delete event occurred\n");
/* Change TRUE to FALSE and the main window will be destroyed with
* a "delete_event". */
return TRUE;
}
/* Another callback */
static void destroy( GtkWidget *widget,
gpointer data )
{
gtk_main_quit ();
}
int main( int argc,
char *argv[] )
{
/* GtkWidget is the storage type for widgets */
GtkWidget *window;
GtkWidget *button;
/* This is called in all GTK applications. Arguments are parsed
* from the command line and are returned to the application. */
gtk_init (&argc, &argv);
/* create a new window */
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
/* When the window is given the "delete_event" signal (this is given
* by the window manager, usually by the "close" option, or on the
* titlebar), we ask it to call the delete_event () function
* as defined above. The data passed to the callback
* function is NULL and is ignored in the callback function. */
g_signal_connect (G_OBJECT (window), "delete_event",
G_CALLBACK (delete_event), NULL);
/* Here we connect the "destroy" event to a signal handler.
* This event occurs when we call gtk_widget_destroy() on the window,
* or if we return FALSE in the "delete_event" callback. */
g_signal_connect (G_OBJECT (window), "destroy",
G_CALLBACK (destroy), NULL);
/* Sets the border width of the window. */
gtk_container_set_border_width (GTK_CONTAINER (window), 50);
/* Creates a new button with the label "Hello World". */
button = gtk_button_new_with_label ("Hello World");
/* When the button receives the "clicked" signal, it will call the
* function hello() passing it NULL as its argument. The hello()
* function is defined above. */
g_signal_connect (G_OBJECT (button), "clicked",
G_CALLBACK (hello), NULL);
/* This will cause the window to be destroyed by calling
* gtk_widget_destroy(window) when "clicked". Again, the destroy
* signal could come from here, or the window manager. */
g_signal_connect_swapped (G_OBJECT (button), "clicked",
G_CALLBACK (gtk_widget_destroy),
G_OBJECT (window));
/* This packs the button into the window (a gtk container). */
gtk_container_add (GTK_CONTAINER (window), button);
/* The final step is to display this newly created widget. */
gtk_widget_show (button);
/* and the window */
gtk_widget_show (window);
/* All GTK applications must have a gtk_main(). Control ends here
* and waits for an event to occur (like a key press or
* mouse event). */
gtk_main ();
return 0;
}
NetBeans 的代码提示:(借用别人的图片)
写完代码后试着运行项目,你会发现出错了。解决办法:
在项目的属性C编译器“命令行->其他选项”选项里添加一行命令行参数
`pkg-config gtk+-2.0 --cflags --libs`
他的意思是把运行gtk 的依赖库包含进来。
注意:这两个 符号:` ` 不是我们常用的那个单引号,而是Tab 键上面一个键的符号。
最后的结果截图:
做完以上工作以后再次运行项目,是不是成功了!
