Gtk basic learning Summary (1), gtk basic learning Summary

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 window

Gtk_window_set_title (window, "window title"); // you can specify a window title.

G_signal_connect (window, "destroy", gtk_main_quit, 0); // set the "destroy" signal (event) processing function "gtk_main_quit ()" of the window ()"

Gtk_widget_show (window); // display window

Gtk_main (); // program Blocking

Return 0;

}

 

I. Common Methods

// Widget operation function

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 operation function

Gtk_window_set_resizable (window, resizable );

Gtk_window_set_position (window, GTK_WIN_POS_CENTER_ALWAYS );

Gtk_window_maximize (window );

Gtk_container_add (widget iner, widget); // load the widget to the container.

 

Gtk_AAA_get_BBB ();

Gtk_AAA_set_BBB ();

// Gtk_widget_set_title (widget, "title ");

 

2. GtkBox 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 text box 1

GtkEntry * entry1 = gtk_entry_new ();

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

Gtk_widget_show (entry1 );

 

3. 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, 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 );

Gtk_widget_show (btn3 );
