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?
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;
}
}
