Creating form for rails-setting

由 谁说胖子不能爱 提交于 2019-12-08 03:54:39
问题 In my Rails app, I'm using the gem rails-settings to save a user's email notification settings. I'm trying to create a form to update a user's notification settings. It should consist of a set of checkboxes where the user selects what they want to receive email notifications about. In the rails-setting README, there are no examples of how to integrate it with a form. The closest tutorial I found was listed in the issues: https://github.com/ledermann/rails-settings/issues/46 But I'm not sure

Android Preferences - changing the order in which they appear

由 百般思念 提交于 2019-12-08 02:47:53
问题 I'm trying to create a hierarchy of classes which start with a PreferenceActivity . The idea is the base class contains the 'About Me' button, then the next class implements the generic preferences for games/apps/wallpapers and then the next class adds the the specifics for each actual Game/App. The idea works well BUT because I'm 'adding' preferences from XML at each level, they appear with the most generic (lowest level) ones first (e.g. my 'About' button). Ideally I'd like them to be the

Does anyone know where OSX stores the settings in System Preferences > Keyboard > Modifier Keys?

由 一个人想着一个人 提交于 2019-12-07 13:04:38
问题 I'm apparently not the only one who wants to know (How can I change modifier keys in "System Preferences > Keyboard > Modifier Keys..."). I've tried watching the System Preferences app with dtruss, but that doesn't seem to be possible on 10.10.3 (which is what I'm on right now), and I'm not even sure that that would be at all useful if System Preferences is just getting settings from cfprefsd. Watching cfprefsd with dtruss doesn't seem to catch the relevant file access. Does anyone know of an

android EditText in preference screen

由 南楼画角 提交于 2019-12-07 11:25:28
Can I put an EditText element in a preference screen? I want to do this to allow fast searching of a large ListPreference by typing, but do not want to save the contents of the search box? Is this possible, or are standard layout controls not allowed on preference screens. The goal is to provide a means of selecting a time-zone and saving it as a preference. Using a ListViewPrefernce alone isn't sufficient because of the huge amount of time-zones that must be scrolled though. Hence, I would like to provide a "hypersearch" type of input box where the user can type a time-zone or part of one to

android shared preferences example for high scores?

由 拜拜、爱过 提交于 2019-12-07 08:44:31
问题 Hi I was wondering is there any simple example of implementing a high score list using shared preferences? ie have pre determined high scores at the start and then update the list dependingt on the score a user gets? 回答1: If you want to use shared preferences the problem is that you can't really store a list or something like that. Shared preferences only supports boolean, float, int, String, long and Set. So your best choice is the Set. There you can convert each value of your highscore to a

CFPreferences creates multiple files

由 廉价感情. 提交于 2019-12-07 08:00:39
问题 I have only a little question: Why the CFPreferences-API creates multiple files in my UserPrefs-Directory? All the files have my Bundle-Identifier as name and all (except the one, the original) have added a suffix like this: com.myComp.myApp.plist <- (only this plist-file should be created) com.myComp.myApp.plist.0qzcicc com.myComp.myApp.plist.8dhjfht 回答1: This looks very much like a side effect of atomic writing. Atomic writing means that, whenever a file is to be written from an NSData (or

问题 I have a preference screen for my application and in the manifest I have given it a theme using: android:theme="@android:style/Theme.Light.WallpaperSettings" However when I nest another preference screen inside this one such as: <?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" android:title="@string/setting_title" android:key="..."> <PreferenceCategory android:title="@string/title_themes" > <PreferenceScreen android:title="

Cursor type in Emacs

由 烈酒焚心 提交于 2019-12-06 20:46:05
问题 What do I put in my .emacs file to change the cursor type for all frames to box ? 回答1: Before Emacs 23.2, you should do : (setq default-cursor-type 'box) Be careful, default-cursor-type is a variable that is obsolete since Emacs 23.2. You should use cursor-type variable instead : (set-default 'cursor-type 'box) 回答2: Got it, it's: (setq default-cursor-type 'box) 来源： https://stackoverflow.com/questions/3670938/cursor-type-in-emacs

Disable sound just for one application

由 梦想的初衷 提交于 2019-12-06 15:59:49
Is it possible to turn off all sounds of just one app and to save the choice until the next start of the app? So I have a ToggleButton at the StartActivity and by pressing this Button, all sounds of the app should be deactivated, but sounds of other apps should still be working. I tried it with Preferences, using the SharedPreferences class, an xml file and so on, like in my book. But going through the introduction i realized, that the Preferences are just a way to save data permanent. So I would have to include for example on every Button with a sound an if-clause that checks if this or that

Android switching between PreferenceScreens

由 时间秒杀一切 提交于 2019-12-06 15:43:30
I have a PreferencesScreen, that has some Preferences and a sub-screen. It looks like this: <PreferenceScreen android:key="root"> <Preference android:key="first" /> <PreferenceScreen android:key="subScreen" /> <Preference android:key="second" /> <Preference android:key="third" /> </PreferenceScreen> </PreferenceScreen> When user clicks the subscreen, he is moved to the subscreen view. Now I want to redirect the user to "root" preference screen when he clicks on "second" or "third". I don't seem to find the right API to either close the subscreen, or focus the previous one. Ideas?
