Is there a way to open a new folder by double-clicking a tab?
The current behavior is that the tab will be closed.
You can double-click the tab bar background (not one of the tabs) to open a tab, if that's enabled under Preferences / Folder Tabs / Folder Tab Bar.
There's also an OnTabClick scripting event which you could probably use to make double-clicking the tabs themselves open a new tab. (You'd want to turn off Preferences / Folder Tabs / Options / Double-click tabs to close them, too.)
What wording do I need to set Left DoubleClick in tabClickData.qualifiers?
function OnTabClick(tabClickData)
{
var cmd = DOpus.Create.Command;
var cmdstring;
DOpus.output("tabClickData.qualifiers = " + tabClickData.qualifiers);
if (tabClickData.qualifiers=="")cmdstring = "Go CURRENT NEW";
if (typeof cmdstring!="undefined"){
DOpus.output("cmdstring = " + cmdstring);
cmd.runcommand(cmdstring);
}
}
