布局管理

 

布局容器： GtkAlignment,GtkFixed,GtkVBox和GtkTable

 

GtkFixed

GtkFixed容器中的子部件的位置和大小固定。

#include <gtk/gtk.h>

int main( int argc, char *argv[])
{
  GtkWidget *window;
  GtkWidget *fixed;

  GtkWidget *button1;
  GtkWidget *button2;
  GtkWidget *button3;

  gtk_init(&argc, &argv);

  window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
  gtk_window_set_title(GTK_WINDOW(window), "GtkFixed");
  gtk_window_set_default_size(GTK_WINDOW(window), 290, 200);
  gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);

  fixed = gtk_fixed_new();
  gtk_container_add(GTK_CONTAINER(window), fixed);

  button1 = gtk_button_new_with_label("Button");
  gtk_fixed_put(GTK_FIXED(fixed), button1, 150, 50);
  gtk_widget_set_size_request(button1, 80, 35);

  button2 = gtk_button_new_with_label("Button");
  gtk_fixed_put(GTK_FIXED(fixed), button2, 15, 15);
  gtk_widget_set_size_request(button2, 80, 35);

  button3 = gtk_button_new_with_label("Button");
  gtk_fixed_put(GTK_FIXED(fixed), button3, 100, 100);
  gtk_widget_set_size_request(button3, 80, 35);

  g_signal_connect_swapped(G_OBJECT(window), "destroy",
      G_CALLBACK(gtk_main_quit), NULL);

  gtk_widget_show_all(window);

  gtk_main();

  return 0;
}

 

GtkVBox 垂直盒子容器

GtkHBox 水平盒子容器

 

#include <gtk/gtk.h>

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

  GtkWidget *window;
  GtkWidget *vbox;

  GtkWidget *settings;
  GtkWidget *accounts;
  GtkWidget *loans;
  GtkWidget *cash;
  GtkWidget *debts;

  gtk_init(&argc, &argv);

  window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
  gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);
  gtk_window_set_default_size(GTK_WINDOW(window), 230, 250);
  gtk_window_set_title(GTK_WINDOW(window), "GtkVBox");
  gtk_container_set_border_width(GTK_CONTAINER(window), 5);

  vbox = gtk_vbox_new(TRUE, 1);//垂直盒子容器
  gtk_container_add(GTK_CONTAINER(window), vbox);

  settings = gtk_button_new_with_label("Settings");
  accounts = gtk_button_new_with_label("Accounts");
  loans = gtk_button_new_with_label("Loans");
  cash = gtk_button_new_with_label("Cash");
  debts = gtk_button_new_with_label("Debts");

  gtk_box_pack_start(GTK_BOX(vbox), settings, TRUE, TRUE, 0);
  gtk_box_pack_start(GTK_BOX(vbox), accounts, TRUE, TRUE, 0);
  gtk_box_pack_start(GTK_BOX(vbox), loans, TRUE, TRUE, 0);
  gtk_box_pack_start(GTK_BOX(vbox), cash, TRUE, TRUE, 0);
  gtk_box_pack_start(GTK_BOX(vbox), debts, TRUE, TRUE, 0);

  g_signal_connect_swapped(G_OBJECT(window), "destroy",
        G_CALLBACK(gtk_main_quit), G_OBJECT(window));

  gtk_widget_show_all(window);

  gtk_main();

  return 0;
}

GtkTable 表容器

 

#include <gtk/gtk.h>

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

  GtkWidget *window;

  GtkWidget *table;
  GtkWidget *button;

  char *values[16] = { "7", "8", "9", "/",
     "4", "5", "6", "*",
     "1", "2", "3", "-",
     "0", ".", "=", "+"
  };

  gtk_init(&argc, &argv);

  window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
  gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);
  gtk_window_set_default_size(GTK_WINDOW(window), 250, 180);
  gtk_window_set_title(GTK_WINDOW(window), "GtkTable");

  gtk_container_set_border_width(GTK_CONTAINER(window), 5);

  table = gtk_table_new(4, 4, TRUE);
  gtk_table_set_row_spacings(GTK_TABLE(table), 2);
  gtk_table_set_col_spacings(GTK_TABLE(table), 2);

  int i = 0;
  int j = 0;
  int pos = 0;

  for( i=0; i < 4; i++) {
    for( j=0; j < 4; j++) {
      button = gtk_button_new_with_label(values[pos]);
      gtk_table_attach_defaults(GTK_TABLE(table), button, j, j+1, i, i+1 );
      pos++;
    }
  }

  gtk_container_add(GTK_CONTAINER(window), table);

  g_signal_connect_swapped(G_OBJECT(window), "destroy",
        G_CALLBACK(gtk_main_quit), G_OBJECT(window));

  gtk_widget_show_all(window);

  gtk_main();

  return 0;
}

{

  GtkWidget *window;
  GtkWidget *ok;
