GTK v1.2 Tutorial(英文)

来源:Linux-cn.com 作者:Webmaster 时间:2007-05-05 点击: [收藏] [投稿]

void gtk_notebook_set_show_tabs( GtkNotebook *notebook,
gboolean show_tabs);
void gtk_notebook_set_show_border( GtkNotebook *notebook,
gboolean show_border );

  The next function is useful when the you have a large number of pages, and the tabs don't fit on the page. It allows the tabs to be scrolled through using two arrow buttons.


void gtk_notebook_set_scrollable( GtkNotebook *notebook,
gboolean scrollable );

  show_tabs, show_border and scrollable can be either TRUE or FALSE.

  Now let's look at an example, it is expanded from the testgtk.c code that comes with the GTK distribution. This small program creates a window with a notebook and six buttons. The notebook contains 11 pages, added in three different ways, appended, inserted, and prepended. The buttons allow you rotate the tab positions, add/remove the tabs and border, remove a page, change pages in both a forward and backward manner, and exit the program.


/* example-start notebook notebook.c */
#include <stdio.h>
#include <gtk/gtk.h>
/* This function rotates the position of the tabs */
void rotate_book( GtkButton *button,GtkNotebook *notebook )
{
gtk_notebook_set_tab_pos (notebook, (notebook->tab_pos +1) %4);
}
/* Add/Remove the page tabs and the borders */
void tabsborder_book( GtkButton *button,GtkNotebook *notebook )
{
gint tval = FALSE;
gint bval = FALSE;
if (notebook->show_tabs == 0)
tval = TRUE; 
if (notebook->show_border == 0)
bval = TRUE;
gtk_notebook_set_show_tabs (notebook, tval);
gtk_notebook_set_show_border (notebook, bval);
}
/* Remove a page from the notebook */
void remove_book( GtkButton *button,
GtkNotebook *notebook )
{
gint page;
page = gtk_notebook_get_current_page(notebook);
gtk_notebook_remove_page (notebook, page);
/* Need to refresh the widget -- 
 This forces the widget to redraw itself. */
gtk_widget_draw(GTK_WIDGET(notebook), NULL);
