ICSharpCode.TextEditor垂直滚动

问题描述

是否可以在ICSharpCode.TextEditor中配置垂直滚动，以便默认情况下看不到垂直滚动条.而且只有当有人键入很多行(超出此控件的当前高度)时，垂直滚动条才会自动出现.如果是，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

您可以轻松添加函数:

1)转到名称空间ICSharpCode.TextEditor并打开TextAreaControl类.文件位置为:C:... \ ICSharpCode.TextEditor \ Project \ Src \ Gui \ 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)添加一种方法来设置水平"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)在带有TextEditor的项目中，这就是调用ShowScrollBars()方法的方式:

3) In the project with the TextEditor, this is how you call the ShowScrollBars() method:

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

此代码可以根据文本行数显示垂直滚动条:

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中:

In the TextAreaControl:

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