focus

问题 I have been filtering my way through jQuery tooltip plugins and have found tipsy. It is used by GitHub, that was what I based most of my decision on. I really like it and it is really easy to use. I am having a problem with it though. I need the tooltip to fade in on focus, not hover. It currently works but only on hover. Here is my current code: $('input.tip').tipsy({trigger: 'focus', gravity: 'w', fade: true}); With or without trigger: 'hover', makes no difference. I read the docs

问题 I have a wxFrame that receives events. Whenever an event comes in, I want the frame to be brought to the foreground.
