问:
如果想初始化具有特定值的bhatch对话框或保留对话框以前的值,应该怎么做/p>
答:
请检查下面的代码,演示如何覆盖默认的bHatch命令实现并使用特定值调用对话框。
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; }}
