ParmObject to drop dialog

I have a drop dialog form and I need to pass an object into it from the caller form. To set parmObject, I usually use an override of clicked() similar to this:

void clicked()
{
    Args args = new Args();

    args.caller(element);
    args.parmObject(someObject);
    args.record(someTable);

    this.menuFunction().run(args);
}

It works well for normal menu item buttons, but not for drop dialogs, because MenuFunction.run() isn't aware of that I want to open the form as a drop dialog.

To solve this problem, I would need either to find a correct way of opening drop dialogs from code, or to set parmObject() without overriding clicked() of the DropDialogButton.

I will be surprised if it can be done, but if it is, it will be useful to learn.

I surely can use a workaround, such as exposing the object by a method on the caller form, but the resulting form is uglier and more tightly coupled with a particular caller form than if I just get an object and check its type.

Ok - tnx!

I decided to use the caller to provide the parameter object - even there is the possibility to use this.parameters() in clicked event to provide a string to the dialog's args.parm() property. I prefere to have the object instance then to serialize and deserialize it.

No; it seems that I was right in assuming that it can't be done directly.

I used the workaround mentioned at the end of my post. This is (roughly) what I do in init() of the dialog form:

Object caller = element.args().caller() as FormRun; if (caller && formHasMethod(caller, identifierStr(getMyObject))) { myObject = caller.getMyObject(); }
