Recalling a form in Opus

I don't think you can reliably re-use the exact same dlg object, but you can create a second dlg object for the same dialog without any issues.

Example using a detached dialog:

function OnClick(clickData)
{
	for (var showCount = 0; showCount < 2; ++showCount)
	{
	    var Dlg = DOpus.Dlg;
	    Dlg.window = clickData.func.sourcetab;
	    Dlg.template = "dialog1";
	    Dlg.detach = true;
		Dlg.Create();

		var listview = Dlg.Control("listview1");
		var i = listview.AddItem("Line 1");
		listview.GetItemAt(i).subitems(0) = "L1.0";
		listview.GetItemAt(i).subitems(1) = "L1.1";
		i = listview.AddItem("Line 2");
		listview.GetItemAt(i).subitems(0) = "L2.0";
		listview.GetItemAt(i).subitems(1) = "L2.1";

	    Dlg.Show();
	    while (true)
		{
	        var Msg = Dlg.GetMsg();
	        if (!Msg.result) break;
	        DOpus.Output("Msg Event = " + Msg.event);
			if (Msg.event == "click" && Msg.control == "Autosize")
			{
				listview.columns.AutoSize();
			}
		}
	    DOpus.Output("Return code = " + Dlg.result);
    }
}
