• Gtk基础学习总结(一)


    第一个GTK程序例子:

    #include <stdio.h>

    #include <gtk/gtk.h>

    int main(int argc, char *argv[])

    {  

       gtk_init(NULL,NULL);                       //初始化GTK  

       GtkWindow *window =gtk_window_new(GTK_WINDOW_TOPLEVEL);   //新建一个window窗口 

       gtk_window_set_title(window,"窗口标题");           //设置窗口标题  

       g_signal_connect(window,"destroy",gtk_main_quit,0);      //设置窗口的"destroy"信号(事件)的处理函数“gtk_main_quit()”  

       gtk_widget_show(window);                   //显示窗口

       gtk_main();                          //程序阻塞  

       return 0;

    }


    一、常用方法

    //widget操作函数

      void gtk_widget_show(widget);

      void gtk_widget_hide(widget);

      void gtk_widget_set_sensitive(widget,sensitive);

      void gtk_widget_set_size_request(widget,width,height);

    //window操作函数

      gtk_window_set_resizable(window,resizable);

      gtk_window_set_position(window,GTK_WIN_POS_CENTER_ALWAYS);

      gtk_window_maximize(window);

      gtk_container_add(container,widget);    //将widget装到container中

      gtk_AAA_get_BBB();

      gtk_AAA_set_BBB();  

      //gtk_widget_set_title(widget,"标题");


    二、GtkBox(盒子)布局

    //创建盒子

      GtkBox *box1=gtk_box_new(GTK_ORIENTATION_HORIZONTAL,0);  

      //GtkBox *box1=gtk_box_new(GTK_ORIENTATION_VERTICAL,0);  

      gtk_container_add(window,box1);  

      gtk_widget_show(box1);

     //添加按钮1  

      GtkButton *btn1=gtk_button_new();  

      gtk_button_set_label(btn1,"按钮1");  

      gtk_box_pack_start(box1,btn1,FALSE,FALSE,0);        

      gtk_widget_show(btn1);    

    //添加按钮2

      GtkButton *btn2=gtk_button_new();  

      gtk_button_set_label(btn2,"按钮2");  

      gtk_box_pack_start(box1,btn2,FALSE,FALSE,0);        

      gtk_widget_show(btn2);    

    //添加文本框1  

      GtkEntry *entry1=gtk_entry_new();  

      gtk_box_pack_start(box1,entry1,FALSE,FALSE,0);        

      gtk_widget_show(entry1);


    三、网格布局

     /*       

        GtkGrid *grid1=gtk_grid_new();

      gtk_container_add(window,grid1);

      gtk_widget_show(grid1);

      //gtk_grid_attack(GtkGrid,widget,int left,int top,int width,int height);

         //添加按钮1

      GtkButton *btn1=gtk_button_new();

         gtk_button_set_label(btn1,"按钮1");  

       gtk_grid_attach(grid1,btn1,0,0,1,1);

       gtk_widget_show(btn1);

          //添加按钮2

      GtkButton *btn2=gtk_button_new();  

      gtk_button_set_label(btn2,"按钮2");  

      gtk_grid_attach(grid1,btn2,1,0,1,1);  

      gtk_widget_show(btn2);

         //添加按钮3

      GtkButton *btn3=gtk_button_new();  

      gtk_button_set_label(btn3,"按钮3");  

      gtk_grid_attach(grid1,btn3,0,1,2,2);  

      gtk_widget_show(btn3);    

    */
