新手入門必看：VectorDraw 常見問題整理大全（八）

---

VectorDraw Developer Framework（VDF）是一個用于應用程序可視化的圖形引擎庫。有了VDF提供的功能，您可以輕松地創建、編輯、管理、輸出、輸入和打印2D和3D圖形文件。該庫還支持許多矢量和柵格輸入和輸出格式，包括本地PDF和SVG導出。

一. 已編譯的項目無法與安裝的其他VDF版本一起使用

問：我創建了一個使用VectorDraw控件6009編譯的簡單應用程序。所有VectorDraw dll引用都是使用Specific Version = false和Copy Local = false編譯的。此應用程序僅適用于具有VectorDraw 6009的計算機，如果它在VectorDraw 6011計算機上運行則拋出異常。在項目中，我不使用6011中但在6009中丟失或更改的任何屬性/方法/事件？

答：注意：不建議使用以下解決方案。我們建議使用相同的VDF版本構建和重新分發您的應用程序。

您可以通過分發配置文件來重定向VectorDraw dll的版本。

對于VectorDraw程序集dll，配置文件必須如下所示。此外，它必須與您的應用程序.exe放在同一目錄中，并且必須使用格式重命名（yourapplicationname.exe.config）

此配置文件將使用6.1.6011.0重定向所有版本的VectorDraw程序集（請注意，這些dll必須存在于分發計算機中）

相反也是可能的，比如使用6011構建你的exe并使其運行6009安裝。在這種情況下，使用6011構建項目時使用的屬性/方法/事件不應從6011更改為6009。

二. 設置顯示工具提示之前的延遲時間

問：我們在我們的軟件中對某些繪圖對象使用VDraw工具提示。今天，工具提示完全顯示在光標在對象上移動的那一刻。是否可以在顯示工具提示之前設置延遲（例如2秒）？

答：可以通過應用程序中的代碼實現，如下所示。您將需要一個將在MouseMove事件上啟動的Timer，并且在計時器代碼上將顯示一個代碼，該代碼將顯示工具提示。這樣，工具提示將在設置為計時器的時間間隔之后顯示，并且鼠標不在實體上移動。

//On Form Load we initialize the events.
//Note that EnableTooltips is set to False!!!!!
private void Form1_Load(object sender, EventArgs e)
{
//........
vdFramedControl.BaseControl.MouseMove += new MouseEventHandler(BaseControl_MouseMove);
mTimer.Interval = 5000;
mTimer.Tick += new EventHandler(mTimer_Tick);
vdFramedControl.BaseControl.ActiveDocument.EnableToolTips = false;
mTimer.Start();
}

//On mouse move we constantly reset the timer
void BaseControl_MouseMove(object sender, MouseEventArgs e)
{
mTimer.Stop();
mTimer.Start();
}

//On the timer's code we write the following in order to show the tooltip
void mTimer_Tick(object sender, EventArgs e)
{
if (!vdFramedControl.BaseControl.Visible) return;
if (vdFramedControl.BaseControl.ActiveDocument.ActiveLayOut.OverAllActiveActions.Count > 1) return;
VectorDraw.Actions.BaseAction action = vdFramedControl.BaseControl.ActiveDocument.ActiveLayOut.OverAllActiveAction;
if (!action.IsVisible) return;
vdFramedControl.BaseControl.ActiveDocument.EnableToolTips = true;
//This will show the tooltip if there is any!!!!
action.MouseMove(new MouseEventArgs(MouseButtons.None, 0, action.GdiMouseLocation.X, action.GdiMouseLocation.Y, 0), action.MouseLocation, action.OrthoPoint);
vdFramedControl.BaseControl.ActiveDocument.EnableToolTips = false;
}

//Don't forget to do the finalizations at the closing of the application
protected override void OnClosing(CancelEventArgs e)
{
mTimer.Tick -= new EventHandler(mTimer_Tick);
vdFramedControl.BaseControl.MouseMove -= new MouseEventHandler(BaseControl_MouseMove);
mTimer.Stop();
mTimer.Dispose();
base.OnClosing(e);
}

三. 過濾選擇文檔特定布局的所有圖層的所有折線

問：如何過濾選擇文檔特定布局的所有圖層的所有折線？

答：可通過以下代碼實現：

//Create a selection
VectorDraw.Professional.vdCollections.vdSelection selset = new vdSelection("Myselset");
selset.SetUnRegisterDocument(vdFramedControl1.BaseControl.ActiveDocument);

//Create a filter
VectorDraw.Professional.vdObjects.vdFilterObject filter = new vdFilterObject();

//Add ALL Layer names to the filter(you can add simply 1 layer if you want
foreach (vdLayer var in vdFramedControl1.BaseControl.ActiveDocument.Layers)
{
filter.Layers.AddItem(var.Name);
}

//Add vdPolyline to select all polylines
filter.Types.AddItem("vdPolyline");

//Add the name of the layout you want to check if no name is specified then ALL layouts will be checked
filter.LayOuts.AddItem(vdFramedControl1.BaseControl.ActiveDocument.ActiveLayOut.Name);

//Apply the filter. After this the selection will contain the selected polylines.
selset.FilterSelect(filter);

四. 不想顯示選擇交叉綠色和窗口藍色矩形以及不在夾點選擇中添加的所選實體

問：我不想顯示選擇交叉綠色和窗口藍色矩形以及不在夾點選擇中添加的所選實體，可以怎么做？

答：應用程序表單中的帶有vdFrameControl的C＃中的示例：

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

using VectorDraw.Professional.vdCollections;

namespace WindowsApplication1

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

protected override void OnLoad(EventArgs e)

{

base.OnLoad(e);

//do not show the green and blue selecting colors

vdFramedControl1.BaseControl.ActiveDocument.GlobalRenderProperties.SelectingCrossColor = Color.Empty;

vdFramedControl1.BaseControl.ActiveDocument.GlobalRenderProperties.SelectingWindowColor = Color.Empty;

vdFramedControl1.BaseControl.ActiveDocument.OnFilterFigure += new VectorDraw.Professional.vdObjects.vdDocument.FilterFigureEventHandler(ActiveDocument_OnFilterFigure);

}

void ActiveDocument_OnFilterFigure(object sender, VectorDraw.Professional.Constants.VdConstFilterFig JobId, VectorDraw.Professional.vdPrimaries.vdFigure fig, ref bool cancel)

{

//do not add the entities in default vdraw grip selections.

if (JobId != VectorDraw.Professional.Constants.VdConstFilterFig.FILTERFIG_SELECT) return;

if (fig == null) return;

vdSelection gripset = sender as vdSelection;

if (gripset == null) return;

if (!gripset.Name.StartsWith("VDGRIPSET")) return;

cancel = true;

//throw new Exception("The method or operation is not implemented.");

}

}

}
