12.6.2 表格控件
（1）创建表格控件
GtkWidget * gtk_clist_new(gint columns)
GtkWidget * gtk_clist_new_with_titles(gint columns,gchar *titles[]) |
参数含义如下。
columns：表格的列数。
titles：各列的列名。
（2）设置每列的长度
void gtk_clist_set_column_width(GtkCList *clist,gint column,gint width) |
参数含义如下。
column：要设置宽度的列编号，从0开始。
width：宽度。
（3）向表格中加入一行数据
gint gtk_clist_append(GtkCList *clist,gchar *text[]) |
（4）获取和设置表格中某个格子的值
gint gtk_clist_get_text(GtkCList *clist,gint row,gint column,gchar **text)
void gtk_clist_set_text(GtkCList *clist,gint row,gint column,gchar **text) |
（5）清除表格中的所有数据
void gtk_clist_clear(GtkCList *clist) |
（6）对表格中的数据进行排序
void gtk_clist_sort_column(GtkCList *clist, gint column)
void gtk_clist_sort (GtkCList *clist) |
（7）获取和设置一行的数据
gpointer gtk_clist_get_row_data(GtkCList *clist,gint row)
void gtk_clist_set_row_data(GtkCList *clist,gint row, gpointer data) |
（8）获取和更改列名
gchar* gtk_clist_get_column_title(GtkCList *clist, gint column)
void gtk_clist_set_column_title(GtkCList *clist, gint column,gchar *title) |
（9）插入和删除一行数据
gint gtk_clist_insert(GtkCList *clist, gint row,gchar *text[])
void gtk_clist_remove(GtkCList *clist, gint row) |
例12-6 表格控件的使用，程序名为table.c
#include int main(int argc,char **argv)
{
GtkWidget *window;
GtkWidget *clist;
gtk_init(&argc,&argv);
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
g_signal_connect(GTK_OBJECT(window),"destroy",
GTK_SIGNAL_FUNC(gtk_main_quit),NULL);
gtk_container_border_width(GTK_CONTAINER(window),20);
char *titles[] = {
"name","age","major"
};
char *rows1[] = {
"John","20","computer"
};
char *rows2[] = {
"Bill","24","maths"
};
char *rows3[] = {
"Martin","22","English"
};
clist = gtk_clist_new_with_titles(3,titles);
gtk_clist_set_column_width(GTK_CLIST(clist),0,50);
gtk_clist_set_column_width(GTK_CLIST(clist),1,50);
gtk_clist_set_column_width(GTK_CLIST(clist),2,150);
gtk_container_add(GTK_CONTAINER(window),clist);
gtk_clist_append(GTK_CLIST(clist),rows1);
gtk_clist_append(GTK_CLIST(clist),rows2);
gtk_clist_append(GTK_CLIST(clist),rows3);
/*获取表格中第0行第2列格子的数据，并在命令行上打印出来*/
char *text = (char *)g_malloc(32);
gtk_clist_get_text(GTK_CLIST(clist),0,2,&text);
g_print("%s\n",text);
gtk_clist_sort(GTK_CLIST(clist));
gtk_widget_show(clist);
gtk_widget_show(window);
gtk_main();
return 0;
