VectorDraw Developer Framework(VDF)是一個用於應用程序可視化的圖形引擎庫。有了VDF提供的功能,您可以輕鬆地創建、編輯、管理、輸出、輸入和打印2D和3D圖形文件。
問:
如果想初始化具有特定值的bhatch對話框或保留對話框以前的值,應該怎麼做?
答:
請檢查下面的代碼,演示如何覆蓋默認的bHatch命令實現並使用特定值調用對話框。
void CommandLine_CommandExecute(string commandname, bool isDefaultImplemented, ref bool success) { if (string.Compare(commandname, "bhatch", true) == 0) { vdDocument doc = vdFramedControl1.BaseControl.ActiveDocument; //Set some initial values for the dialog , This can be global to an application so these values can be changed. //You can call the following dialog with a different constructor (with vdHatchproperties) in order to set these values in a global properties application dialog that you may have. vdHatchProperties SetBhatchInitialValues = new vdHatchProperties(); SetBhatchInitialValues.FillMode = VectorDraw.Professional.Constants.VdConstFill.VdFillModeHatchBlock; SetBhatchInitialValues.FillColor.ColorIndex = 0; //Keep in a variable the current ActiveHatchProperties vdHatchProperties KeepActiveHatch = new vdHatchProperties(); KeepActiveHatch.CopyFrom(doc.ActiveHatchProperties); //Set the ActiveHatchProperties to the above value doc.ActiveHatchProperties.CopyFrom(SetBhatchInitialValues); //Call the dialog. vdFigure ret = VectorDraw.Professional.Dialogs.frmGetHatchDialog.Show(null,doc, doc.ActionControl); //Return ActiveHatchProperties values as it was before the dialog. doc.ActiveHatchProperties.CopyFrom (KeepActiveHatch); success = true; return; } }
