Sorry that's the old one --here is the new one:

Does this really need to be in UIScreen? Can we just implement it in the relevant screen classes in the main PPSSPP project?

[dantheman213]

@hrydgard I was looking through the code and I wrote the new code based off where it seemed to make the most sense.

I also wanted the web server to be stopped automatically as soon as the Back button is pressed on the import/export rom screen. That way less resources are being used on the phone when the transfer server isn't being used as people can be forgetful.

If you think there is a better place to house the code changes I made here can you please be specific as to where I should make those changes? I'm sure you're more familiar with the ins and outs of the project than I am.

Thanks!

Sure, you simply need to add this function to the ImportExport screen class instead, not in this superclass.

@dantheman213 Just to go into more detail:

https://github.com/hrydgard/ppsspp/pull/7885/files#diff-9c6d01ab53b5e80035c125d3bfe17c11R84

class ImportExportFilesScreen : public UIDialogScreenWithBackground {

This is the appropriate place to define ImportExportFilesScreen-specific methods. You would not expect NSArray methods to live on NSObject, would you? The methods aren't necessary for any types of screens other than ImportExporeFilesScreen objects.

It should have both of these methods:

    void AddStopServerBack(UI::ViewGroup *parent);
    UI::EventReturn OnBackServer(UI::EventParams &e);

None of the changes to native or MiscScreens.cpp/h should be necessary. Those changes belong in DevScreens.cpp/h or possibly ImportExportFilesScreen.cpp/h.

Also, this line:

parent->Add(new Choice(di->T("Back"), "", false, new AnchorLayoutParams(150, 64, 10, NONE, NONE, 10)))->OnClick.Handle<UIScreen>(this, &UIScreen::OnBackServer);

Would change to:

parent->Add(new Choice(di->T("Back"), "", false, new AnchorLayoutParams(150, 64, 10, NONE, NONE, 10)))->OnClick.Handle(this, &ImportExportFilesScreen::OnBackServer);

Thanks for the tips. When I get some time I'll implement these and update the PPSSPP pull request.
