c - 如何获取输入文本GTK2 + Glade的值

Question

当我点击send_button_clicked()时；我想获取条目“entryform1”中的值，我该怎么做？我的代码如下:

gtkwidgete1 = GTK_ENTRY( gtk_builder_get_object( gtkBuilder, "chave_Sessao_TextBox" ) );
const gchar *text1 = gtk_entry_get_text(e1);strcpy(ch1,text1);
g_print ("Contents of entries:%s\n", text1);

来自GNOME's GTK+ 2.0 Documentation :

The contents of the Entry can be retrieved by using a call to the following function. This is useful in the callback functions described below:

const gchar *gtk_entry_get_text(GtkEntry *entry);

就这么简单。因此，请执行以下操作:

GtkWidget *e1 = gtk_entry_new();
/* Set up whatever else you want to with your entry here */
g_signal_connect(e1, "activate", G_CALLBACK(print_message, e1));
gtk_box_pack_start (GTK_BOX (yourgtkbox), e1, TRUE, TRUE, 0);
gtk_widget_show(e1);

并在回调函数中print_message打印出消息:

const gchar *text1 = gtk_entry_get_text(GTK_ENTRY (e1));
g_print ("Entry contents: %s\n", text1);

在 GTK 中，gchar 只是 char 的 typedef，因此您无需将其复制到另一个字符串中。
