How to distinct descriptor is in debug console or run console

You can use RunContentManager.getToolWindowByDescriptor().getTitle() to distinguish whether a RunContentDescriptor belongs to a Run or Debug toolwindow. What are you trying to achieve, though? There may be a better possibility.

Dmitry Jemerov, getTitle can't solution all question, since if i run "Ex.java" and debug "Ex.java" too, their title is same, i found the way is following

// the diff is "jdwp"
// debug descriptor
// ExecutionManager.getInstance(curPj()).getContentManager().getAllDescriptors().get(0).getProcessHandler().getCommandLine()

Well, this may work for Java but will definitely not work for any non-JVM-based language. Let me ask again: What are you trying to achieve?

i wanna restart debug console with one key whereever my focus is located in.
