Currently it is not possible to access Define Parameters dialog from API. However you can create your own GUI element which allows to modify the configurable parameters, for GUI extending example see:
https://www.dukascopy.com/wiki/index.php ... _Interface
If you wish to edit the parameters during the strategy run, simply right-click on it in Workspace panel and select Parameters. If you wish to do it from standalone API, retrieve your running strategy from IClient.getStartedStrategies() and then assign a new parameter value, e.g.:
for (IStrategy s : client.getStartedStrategies().values()) {
   MyStrategy strategy = (MyStrategy) s;
   if (strategy != null)
      strategy.intParam = 7;
}

Dear Support,

even if it is not possible to access the Define Parameters dialog from the API, it would be nice to create an own parameter window though.
Could you open this container for access in the API? Or did you use an Open Source one so I can implement this into my projects?

All java swing is at your disposal, so if you wish to create a custom parameters dialog, you can do it in the onStart method of your strategy.

What additional functionality do you require?

I just want to use the Define Parameters dialog as JForex uses it, from your side I do not need any further platform implementation (such as strategy start/stop).
How can I access this Component or instantiate it then?

You can not access it because it is not part of JForex-API. If you wish to have a customized parameters' dialog, consider doing something like this:

Thanks for your example.
It is not the problem to write an own parameter dialog. It is just the work. The point is that your JForex parameter dialog has many specific functions that should be recoded into such an own parameter dialog. Such as date interpretation, or boolean values are displayed as checkboxes automatically, periods are displayed in comboboxes, presets can be organized and much more.
It would be nice to have access to this component (and no need to copy it arduously).

Say there would be an interface
interface IParameterDialogListener{
    void onDialogOpen(IParameterDialog parameterDialog);
    void onDialogClose(IParameterDialog parameterDialog);
}
, where IParameterDialog would hold some properties of the parameter dialog. Please advise what methods would you require for IParameterDialog .
