我已经尝试过 gtk_set_text_view_editable(GTK_TEXT_VIEW(输出字段), FALSE); 但它不起作用。也许我放错地方了，gtk对顺序很敏感，不知道。这是一个缓冲的 TextView 。
有人知道吗？
编辑:
抱歉复制粘贴了所有内容，但到目前为止我不知道问题出在哪里，我不知道要遗漏什么。
我的代码是:
GtkTextBuffer *output_buffer;
GtkTextBuffer *input_buffer;
static gboolean delete(GtkWidget *widget, GtkWidget *event, gpointer data)
{
gtk_main_quit();
printf("Viszlát és kössz a halakat!\n");
return FALSE;
}
static void cnt_btn_clicked(GtkWidget *widget, gpointer data)
{
gchar* msg = "Connect button clicked\n";
gtk_text_buffer_insert_at_cursor(output_buffer,msg,strlen(msg));
}
static void dcnt_btn_clicked(GtkWidget *widget, gpointer data)
{
gchar* msg = "Disconnect button clicked\n";
gtk_text_buffer_insert_at_cursor(output_buffer,msg,strlen(msg));
}

{

}

最佳答案
再次检查您的代码。我相信您的意思是将输入字段设置为可编辑，但实际上您在将输出字段设置为不可编辑后将其设置为可编辑。在代码中搜索所有出现的 outputfield 并检查每一个。这是一个常见的复制粘贴错误。
你有
...
gtk_text_view_set_editable(GTK_TEXT_VIEW(outputfield), FALSE);
...
inputfield = gtk_text_view_new();
gtk_text_view_set_editable(GTK_TEXT_VIEW(outputfield), TRUE);
...
