VectorDraw Developer Framework(VDF)是一個用于應用程式可視化的圖形引擎庫。有了VDF提供的功能,您可以輕松地建立、編輯、管理、輸出、輸入和列印2D和3D圖形檔案。
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,示範如何覆寫預設的bHatch指令實作并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;
}
}
