C语言学习(2)-GTK布局

首先了解下gtk中函数的定义格式:

记住下面几个格式看，下面的代码

1.盒子布局（垂直和水平）

#include <stdio.h>
#include<gtk/gtk.h>
int main(int argc, char *argv[])
{
    //初始化gtk
    gtk_init(NULL,NULL);
    //定义一个指向window的指针
    GtkWindow*window=gtk_window_new(GTK_WINDOW_TOPLEVEL);
    //窗体关闭之后执行
    g_signal_connect(window,"destroy",gtk_main_quit,NULL);
    //设置标题
    gtk_window_set_title(window,"标题");
    //每个被添加的控件都要有show
    gtk_widget_show(window);

    //添加一个box，使用垂直布局
    //GTK_ORIENTATION_HORIZONTAL为水平布局
    GtkBox*box=gtk_box_new(GTK_ORIENTATION_VERTICAL,0);
    gtk_container_add(window,box);
    gtk_widget_show(box);

    GtkLabel*lb1=gtk_label_new("盒子布局");
    gtk_container_add(box,lb1);
    gtk_box_pack_start(box,lb1,FALSE,FALSE,0);
    gtk_widget_show(lb1);

    GtkEntry*entry1=gtk_entry_new();
    gtk_container_add(box,entry1);
    gtk_box_pack_start(box,entry1,FALSE,FALSE,0);
    gtk_widget_show(entry1);

    GtkButton*btn1=gtk_button_new();
    gtk_button_set_label(btn1,"按钮一");
    gtk_container_add(box,btn1);
    gtk_box_pack_start(box,btn1,FALSE,FALSE,0);
    gtk_widget_show(btn1);

    gtk_main();

    return 0;
}

运行结果如下

2.网格布局

原理：

记住几句话：

#include <stdio.h>
#include<gtk/gtk.h>
int main(int argc, char *argv[])
{
    gtk_init(NULL,NULL);
    GtkWindow*window=gtk_window_new(GTK_WINDOW_TOPLEVEL);
    gtk_window_set_title(window,"网格布局");
    g_signal_connect(window,"destroy",gtk_main_quit,NULL);
    gtk_widget_show(window);

    GtkGrid*grid1=gtk_grid_new();
    gtk_container_add(window,grid1);
    gtk_widget_show(grid1);

    GtkButton*btn1=gtk_button_new();
    gtk_button_set_label(btn1,"111111");
    gtk_grid_attach(grid1,btn1,1,1,1,1);
    gtk_container_add(grid1,btn1);
    gtk_widget_show(btn1);

    GtkButton*btn2=gtk_button_new();
    gtk_button_set_label(btn2,"222222");
    gtk_grid_attach(grid1,btn2,0,0,1,1);
    gtk_container_add(grid1,btn2);
    gtk_widget_show(btn2);

    gtk_main();

    return 0;
}

运行结果如下图
