Hi their everybody,
I like to change the possible windowed resolutions of (desktop)
com.jme3.app.SettingsDialog to 16:10 resolutions. For that my
current idea is to change the
com.jme3.app.SettingsDialog.windowedResolutionspublic staticOr are their any other ideas to realize that? Or exist an other communication channel (i.e. mailing list, newsgroup, etc.) to discuss this topic?
Best,
Dirk.
Note: I’m nearly 100% sure that changing the fields to protected is not going to be an acceptable approach. This class isn’t really designed for subclassing and randomly changing some access modifiers doesn’t make it so, either.
However, I’m also curious about a solution because I would like to remove some of the options to eliminate resolutions that would just look crazy in my game and to limit the amount of different nifty screen resolutions I need to support. But it so far hasn’t been a high priority… and forking that class is always a backup plan for me.
Okay,
I’m trying to make com.jme3.app.SettingsDialog ready for subclassing and trying to overload boolean JmeSystem.showSettingsDialog(AppSettings sourceSettings, final boolean loadFromRegistry, SettingsDialog settingsDialog) which get the users subclass as last argument.
If it works I will post a patch 
…
Dirk.
No, this should be added to the appSettings if anything. The only illogical thing is that not every platform has “windowed” resolutions, mostly you get a set of supported resolutions from the system. So this would be some general set of “free” resolutions in the AppSettings.
Okay,
I’m trying to implement a private AppSettings.saveCollection(String name, Collection), private AppSettings.loadCollection(…) These will be called from AppSettings.save() {… saveCollection(“windowedResolutions”, windowedResolutions); …}. The SettingsDialog is calling source.getResolutions(). Okay?
Yeah…
[Edit]: download patch (correct newlines)
Okay,
after applying the patch which is attached the following code snippet should work in a simple application:
String[] res = {“960 x 600”, “768 x 480”};
settings.setWindowedResolutions(res);
String[] depths = {“32 bpp”, “24 bpp”};
settings.setWindowedColorDepths(depths);
JmeSystem.showSettingsDialog(settings, false);
The API and file formats should be 100% backward compatible (hopefully) 
…
Best,
Dirk.
