GTK Basic Learning Summary (i)

Example of the first GTK program:

#include <stdio.h>

#include <gtk/gtk.h>

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

{

Gtk_init (Null,null); Initialize GTK

Gtkwindow *window =gtk_window_new (gtk_window_toplevel); Create a new Windows window

Gtk_window_set_title (window, "Windows title"); Set Window Caption

G_signal_connect (window, "destroy", gtk_main_quit,0); Set the "Destroy" signal (event) handler function for the window "Gtk_main_quit ()"

Gtk_widget_show (window); Display window

Gtk_main (); Program blocking

return 0;

}

First, the common method

Widget manipulation functions

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 action function

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); Install widgets into container

GTK_AAA_GET_BBB ();

GTK_AAA_SET_BBB ();

Gtk_widget_set_title (widget, "title");

Second, gtkbox (box) layout

Create a Box

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);

Add button 1

Gtkbutton *btn1=gtk_button_new ();

Gtk_button_set_label (BTN1, "button 1");

Gtk_box_pack_start (box1,btn1,false,false,0);

Gtk_widget_show (BTN1);

Add button 2

Gtkbutton *btn2=gtk_button_new ();

Gtk_button_set_label (BTN2, "button 2");

Gtk_box_pack_start (box1,btn2,false,false,0);

Gtk_widget_show (BTN2);

Add a text box 1

Gtkentry *entry1=gtk_entry_new ();

Gtk_box_pack_start (box1,entry1,false,false,0);

Gtk_widget_show (Entry1);

Three, Grid layout

/*

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);

Add button 1

Gtkbutton *btn1=gtk_button_new ();

Gtk_button_set_label (BTN1, "button 1");

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

Gtk_widget_show (BTN1);

Add button 2

Gtkbutton *btn2=gtk_button_new ();

Gtk_button_set_label (BTN2, "button 2");

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

Gtk_widget_show (BTN2);

Add button 3

Gtkbutton *btn3=gtk_button_new ();

Gtk_button_set_label (Btn3, "button 3");

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

Gtk_widget_show (BTN3);
