VectorDraw Developer Framework(VDF)是一個(gè)用于應(yīng)用程序可視化的圖形引擎庫(kù)。有了VDF提供的功能,您可以輕松地創(chuàng)建、編輯、管理、輸出、輸入和打印2D和3D圖形文件。該庫(kù)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(dǎo)出。

一. 更改PropertyGrid的寬度和CommandLine的高度
問(wèn):如何在vdFramedControl中更改PropertyGrid的寬度和CommandLine的高度?
答:您可以使用代碼執(zhí)行此操作,例如:
vdFramedC.SetLayoutStyle(vdControls.vdFramedControl.LayoutStyle.CommandLine, true); // Show the CommandLine vdFramedC.SetLayoutStyle(vdControls.vdFramedControl.LayoutStyle.PropertyGrid, true); // Show the PropertyGrid vdFramedC.HistoryLines = 4; // Change CommandLine's Height, changing the history lines that will be displayed vdFramedC.PropertyGridWidth = vdFramedControl.PropertyGridWidth * 2;// Change PropertyGrid's Width
二. 在不將這些操作添加到撤消/重做的情況下進(jìn)行縮放/平移
問(wèn):如何在不使用.NET組件將這些操作添加到撤消/重做列表的情況下進(jìn)行縮放/平移?
答:您可以使用vdDocument事件的onUndoStoreValue,當(dāng)ViewSize或ViewCenter發(fā)生更改時(shí)(這會(huì)發(fā)生縮放和/或平移),然后將Cancel設(shè)置為true。例如:
private void Form1_Load(object sender, EventArgs e) { vdFramedControl1.BaseControl.ActiveDocument.OnUndoStoreValue += new VectorDraw.Professional.vdObjects.vdDocument.UndoStoreValueEventHandler(ActiveDocument_OnUndoStoreValue); } void ActiveDocument_OnUndoStoreValue(object sender, bool isRedo, object propObject, string propName, object value, ref bool Cancel) { if (propName.ToLower() == "viewcenter" || propName.ToLower() == "viewsize") { // zoom pan change ViewCenter and ViewSize Cancel = true; // This will not write to the UNDO the pan/zoom actions } }
對(duì)于7版本的代碼應(yīng)該是:
void ActiveDocument_OnUndoStoreValue(object sender, bool isRedo, object propObject, string propName, object value, ref bool Cancel) { if (propName.ToLower() == "viewcenter" || propName.ToLower() == "viewsize" || propObject.ToString().ToLower() == "zoom") { // zoom & pan change ViewCenter and ViewSize Cancel = true; // This will not write to the UNDO the pan/zoom actions } }
三. 在ACAD中顯示的直徑符號(hào)
問(wèn):如何在ACAD中顯示的直徑符號(hào)?
答:您可以使用vdDocument事件的onUndoStoreValue,當(dāng)ViewSize或ViewCenter發(fā)生更改時(shí)(這會(huì)發(fā)生縮放和/或平移),然后將Cancel設(shè)置為true。例如:
***本文適用于6010及以上版本***
vdDimStyle的新屬性在6010 DiameterSymbol中添加了直徑類型尺寸,RadialSymbol用作徑向類型尺寸的前綴默認(rèn)情況下,“D”用于直徑,“R”用于徑向
您可以通過(guò)實(shí)現(xiàn)以下兩個(gè)事件讓您的應(yīng)用程序使用特定的Diameter和徑向字符串值:
public Form1() { InitializeComponent(); vdFramedControl1.BaseControl.AfterNewDocument += new VectorDraw.Professional.Control.AfterNewDocumentEventHandler(BaseControl_AfterNewDocument); vdFramedControl1.BaseControl.AfterOpenDocument += new VectorDraw.Professional.Control.AfterOpenDocumentEventHandler(BaseControl_AfterOpenDocument); } void ChangeDimensionsStylePrefix(string PrefixDiameter,string PrefixRadial) { foreach (vdDimstyle style in vdFramedControl1.BaseControl.ActiveDocument.DimStyles) { style.DiameterSymbol = PrefixDiameter; style.RadialSymbol = PrefixRadial; } } void BaseControl_AfterOpenDocument(object sender) { ChangeDimensionsStylePrefix("%%c","r"); } void BaseControl_AfterNewDocument(object sender) { ChangeDimensionsStylePrefix("%%c","r"); }
四. 獲取圖形中使用的所有collors(可見(jiàn)實(shí)體)
問(wèn):想從屏幕上繪制的實(shí)體中獲取顏色,所以如何獲取圖形中使用的所有collors(可見(jiàn)實(shí)體)?
答:請(qǐng)參閱下面的代碼。它是在C#2005中使用vdFramed控件。調(diào)用onDrawFigure事件,從此事件的渲染中可以獲得PenStyle.Color。
System.Collections.Generic.Dictionary<int, System.Drawing.Color> dictionarycolor; private bool countcolors = false; public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { vdFC.BaseControl.ActiveDocument.FreezeEntityDrawEvents.Push(false); vdFC.BaseControl.ActiveDocument.OnDrawFigure += new VectorDraw.Professional.vdObjects.vdDocument.FigureDrawEventHandler(ActiveDocument_OnDrawFigure); // this event is needed. The render of this event has the PenStyle.Color } private void button3_Click(object sender, EventArgs e) { //create a dictionary to filter dublicate colors dictionarycolor = new Dictionary<int, Color>(); countcolors = true; vdFC.BaseControl.ActiveDocument.Open(vdFC.BaseControl.ActiveDocument.GetOpenFileNameDlg(0, "", 0) as string); vdFC.BaseControl.ActiveDocument.Redraw(true); countcolors = false; //put the colors from dictionary in a simple array of System colors. System.Drawing.Color[] usedcolors = new Color[dictionarycolor.Count]; int i = 0; foreach (System.Collections.Generic.KeyValuePair<int,System.Drawing.Color> var in dictionarycolor) { usedcolors.SetValue(var.Value,i ); i++; } MessageBox.Show("different colors used : "+ i.ToString()); } void ActiveDocument_OnDrawFigure(object sender, VectorDraw.Render.vdRender render, ref bool cancel) { if (countcolors) { int key = render.PenStyle.color.GetHashCode(); if(dictionarycolor.ContainsKey(key)) return; dictionarycolor.Add(key, render.SystemPenColor); //add the color to the dictionary if doesn't already exist } }
五. 在vdraw的DblClick事件后顯示模式對(duì)話框時(shí)如何克服焦點(diǎn)問(wèn)題
問(wèn):在Wrapper中,當(dāng)DblClick發(fā)生時(shí),此事件的處理程序中顯示的模態(tài)形式?jīng)]有焦點(diǎn),所以如何在vdraw的DblClick事件后顯示模式對(duì)話框時(shí)如何克服焦點(diǎn)問(wèn)題?
答:***此解決方案適用于6009及以上版本***
您可以使用CommandID事件和PostCommandID方法輕松解決此問(wèn)題。請(qǐng)參閱以下代碼:
void CAdd3dEntitiesDlg::DblClickVdpro1() { m_vdraw.PostCommandId(555); } void CAdd3dEntitiesDlg::CommandIdVdpro1(long cmdid) { if(cmdid == 555){ MyTest Dlg; Dlg.DoModal(); } }
