问题 how to place cursor in a text input when user login form comes. I want cursor place in username text input. .Any help is greatly appreciated! 回答1: To go along with J_A_X's answer, if you're trying to set focus on a component when the application first loads, you'll also need to use some javascript to set the focus on your SWF.

问题 I am just programming a language learning app in Flex for various Asian languages. As some of these languages have very big font sizes (e.g. Chinese), I do not want to load all these fonts into the app. at once but was thinking to put them into different modules and then load only the specific module (depending on which language is chosen in the main app). For this I moved the style part from the main app: <mx:Style> @font-face { font-family:DedicatedFont; src: url('assets/fonts/cma.ttf');

问题 Can any one tell me about what is the Difference between validateProperties() and invalidateProperties() ? 回答1: invalidateProperties: Marks a component so that its commitProperties() method gets called during a later screen update. Invalidation is a useful mechanism for eliminating duplicate work by delaying processing of changes to a component until a later screen update. For example, if you want to change the text color and size, it would be wasteful to update the color immediately after

The user clicks a link, and then selects a file using the FileReference class. The FileReference class doesn't attach cookie information, so I can't use a session. I want to implement a 2 step process where the client first pings the server to get a one-time-use token, and then does the upload or
