ICSharp code.TextEditor Veritical滚动 [英] ICSharpCode.TextEditor Veritical Scrolling

问题描述

是否可以设置垂直滚动的ICSharp code.TextEditor例如，默认情况下没有垂直滚动条是可见的。而且，只有当有人类型很多线路（超出此控件的当前高度），一个垂直滚动条会自动出现。如果是的话，怎么办？

Is it possible to configure vertical scrolling in ICSharpCode.TextEditor such that by default no vertical scrollbar is visible. And that only when someone types a lot of lines (beyond current height of this control) that a vertical scrollbar appears automatically. If yes, how?

推荐答案

它很容易将自己加入的功能：

1）转到命名空间 ICSharp code.TextEditor ，然后打开 TextAreaControl 类。该文件的位置为：C：\ ICSharp code.TextEditor \项目的\ src \桂\ TextAreaControl.cs

1) Goto the namespace ICSharpCode.TextEditor and open the TextAreaControl class. The file location is: C:...\ICSharpCode.TextEditor\Project\Src\Gui\TextAreaControl.cs

2）添加一个方法来设置水平或垂直滚动​​条的可见性：

2) Add a method to set the visibility of the Horizontal or Vertical scrollbar:

public void ShowScrollBars(Orientation orientation,bool isVisible)
{
    if (orientation == Orientation.Vertical)
    {
        vScrollBar.Visible = isVisible;
    }
    else
    {
        hScrollBar.Visible = isVisible;
    }
}

3）与文本编辑的项目，这是你如何调用 ShowScrollBars（）方法：

editor.ActiveTextAreaControl.ShowScrollBars(Orientation.Vertical,false);

这code的伎俩，以显示基于文本行数垂直滚动条：

This code does the trick to show the vertical scrollbar based on the number of text lines:

public TextEditorForm()
{
    InitializeComponent();
    AddNewTextEditor("New file");
    SetSyntaxHighlighting("Mathematica");    
    editor.ActiveTextAreaControl.TextEditorProperties.IndentationSize = 0;
    editor.ActiveTextAreaControl.ShowScrollBars(Orientation.Vertical,false);
    editor.TextChanged += new EventHandler(editor_TextChanged);
}

void editor_TextChanged(object sender, EventArgs e)
{            
    bool isVisible = (editor.ActiveTextAreaControl.GetTotalNumberOfLines > editor.ActiveTextAreaControl.TextArea.TextView.VisibleLineCount);
    editor.ActiveTextAreaControl.ShowScrollBars(Orientation.Vertical, isVisible);               
}

在TextAreaControl：

In the TextAreaControl:

public int GetTotalNumberOfLines()
{
    return this.Document.TotalNumberOfLines;
}
