EditPoint.TryToShow 方法 (vsPaneShowHow, Object)

2011-08-12

尝试显示文本点的位置。

命名空间： EnvDTE
程序集： EnvDTE（在 EnvDTE.dll 中）

语法

声明
Function TryToShow ( _
    How As vsPaneShowHow, _
    PointOrCount As Object _
) As Boolean

bool TryToShow(
    vsPaneShowHow How,
    Object PointOrCount
)

bool TryToShow(
    [InAttribute] vsPaneShowHow How, 
    [InAttribute] Object^ PointOrCount
)

abstract TryToShow : 
        How:vsPaneShowHow * 
        PointOrCount:Object -> bool

function TryToShow(
    How : vsPaneShowHow, 
    PointOrCount : Object
) : boolean

参数

How
类型：EnvDTE.vsPaneShowHow
可选。一个 vsPaneShowHow 常数，该常数确定代码的显示方式。

PointOrCount
类型：System.Object
可选。要显示的文本的选定范围的终结点。它可以是一个 TextPoint，也可以是一个整数。

返回值

类型：System.Boolean
如果文本的跨距在当前代码编辑器内，则为 true；否则为 false。

实现

TextPoint.TryToShow(vsPaneShowHow, Object)

备注

如果可能，TryToShow 调整代码视图中缓冲区的位置，以便在代码编辑器中显示指示的文本范围。 TryToShow 与 TextPane 对象的 Activate 方法相似，不同的是它尝试显示窗口和指定的文本范围。

示例

Sub TryToShowExample(ByVal dte As DTE2)

    ' Before running this example, open a text document.
    Dim win As Window = dte.ActiveWindow
    Dim textWin As TextWindow = CType(win.Object, TextWindow)

    ' Split the text document window.
    Dim cmd As Command = dte.Commands.Item("Window.Split")
    dte.Commands.Raise(cmd.Guid, cmd.ID, Nothing, Nothing)

    ' Display the beginning of the document in the top pane and the 
    ' end of the document in the bottom pane.
    Dim sel As TextSelection = textWin.Panes.Item(2).Selection
    sel.StartOfDocument()
    sel.ActivePoint.TryToShow()
    sel = textWin.Panes.Item(1).Selection
    sel.EndOfDocument()
    sel.ActivePoint.TryToShow()

End Sub

public void TryToShowExample(DTE2 dte)
{
    // Before running this example, open a text document.
    Window win = dte.ActiveWindow;
    TextWindow textWin = (TextWindow)win.Object;

    // Split the text document window.
    Command cmd = dte.Commands.Item("Window.Split", -1);
    object dummy = null;
    dte.Commands.Raise(cmd.Guid, cmd.ID, ref dummy, ref dummy);

    // Display the beginning of the document in the top pane and the 
    // end of the document in the bottom pane.
    TextSelection sel = textWin.Panes.Item(2).Selection;
    sel.StartOfDocument(false);
    sel.ActivePoint.TryToShow(vsPaneShowHow.vsPaneShowCentered, null);
    sel = textWin.Panes.Item(1).Selection;
    sel.EndOfDocument(false);
    sel.ActivePoint.TryToShow(vsPaneShowHow.vsPaneShowCentered, null);
}
