我想給我的文本編輯器多頁面模式問題是當richtextbox達到最後一行它調整大小,並添加一個滾動條,這不是我想要的,我做了一個代碼RichTextBox的最後一行轉移到下面的一個,但它的移動的全部文本,而不是和它是一種緩慢的,任何幫助,將不勝感激使用richtextboxes使多個頁面的文本編輯器
public partial class Form1 : Form

protected static bool GetVisibleScrollbars(Control ctl)

pages.Add(B);

對於一個SO問題,IMO太多的代碼。 –
對不起在這裏 – Untouchable
我認爲問題是使用計時器來移動線條,但是idk還應該使用其他線程idk在這裏呆了幾天...... – Untouchable
