fallback

Is there a way to have another binding as a fallback value? I'm trying to do something like this: <Label Content="{Binding SelectedItem.Name, ElementName=groupTreeView, FallbackValue={Binding RootGroup.Name}}" /> If anyone's got another trick to pull it off, that would be great. What you are looking for is something called PriorityBinding (#6 on this list) (from the article) The point to PriorityBinding is to name multiple data bindings in order of most desirable to least desirable. This way if the first binding fails, is empty and/or default, another binding can take it's place. e.g. <TextBox

I'm working in the internationalization/localization of web site using Globalize3 and easy_globalize_accesors and right now I'm adapting the forms to manage fields with possible translations. Suppose I have a class named Role: class Role translates :name, :fallbacks_for_empty_translations => true # rest of class definition I've done this because I want to show the default translation if there isn't a translation or is empty in the current locale and this works as expected. But, in my form I want the opposite: I would like to have each input who refers to a different locale than default locale

I have some HTML5 videos with animated GIFs as fallback. Sadly, the GIFs are being loaded even though HTML5 video is supported. Without using javascript, is there a way to stop the browser from downloading HTML5 fallback content? If not, I will just use jquery but wanted to know if there was a non-js solution. <video> <source src="animation-1.mp4" type="video/mp4"> <img src="animation-1.gif"> </video> <video> <source src="animation-2.mp4" type="video/mp4"> <img src="animation-2.gif"> </video> <video> <source src="animation-3.mp4" type="video/mp4"> <img src="animation-3.gif"> </video> Network

We are planning to utilize Spring Cloud Config for our service. Our biggest concern is that when the container starts up, it relies on github to be available all the time so that it can pull the config files. In case github is down, what is the best practice to mitigate the issue? I was thinking of storing a local folder of the configs as a backup and configuring the application.yml to fallback to it (I do not know how). I was going to use a Composite Environment Repositories Please see here: Section 2.1.8 However it states: Any type of failure when retrieving values from an environment

I'm interested in knowing where font fallback fits in the font shaping/rendering stack. In other words, at what point are missing glyphs detected and how are they substituted? I see in this document that the FontConfig tool does font fallback "based on glyph coverage transparently." So the questions are: How exactly does this algorithm work? Is this the standard algorithm used by most browsers - webkit, gecko (probably not IE)? How does font fallback based on missing glyphs within a font that does exist relate to CSS font fallback (which specifies which fonts to use in turn, when a font is

I'm using g.drawString(str, x, y) to draw a String with a Graphics2D object g . The current font of g does not cover all the characters of str (I have e.g. Chinese chars in there). On Mac OS X, a fallback font seems to be automatically used, but not on Windows, where black square outlines appear instead of the wanted characters. Why is the behavior different depending on the platform? How do I specify a fallback font (or several fallback fonts) in case of missing characters? (For instance, one of the nice fonts there .) Update/More Info So, the original font that doesn't support all characters
