痞子三分冷 提交于 2019-11-29 11:12:57
I have this code: Synthesizer synthesizer = MidiSystem.getSynthesizer(); synthesizer.open(); Instrument[] instrument = synthesizer.getDefaultSoundbank().getInstruments(); synthesizer.loadInstrument(instrument[29]); MidiChannel[] channels = synthesizer.getChannels(); MidiChannel channel = channels[1]; channel.programChange(29); channel.noteOn(noteNumber, 127); Teszthang.sleep(2000); channel.noteOff(noteNumber); so this is an example, to play a sound in max volume (127) for 2 seconds. but i want to control the channel's volume, like after 2 seconds, the volume fade out in an another 2 seconds.

Jquery fadeout text insde a text box and textarea

Hi this should be a really easy problem but i am stuck. Is it possible to fade out the text inside a text box and textarea and leave the actual element in place. I have tried fading out using .html() .val() etc but the element that the text is in is always faded too. I think the only way to achieve this is by manipulating the input element's colour. Check out the JQuery color plugin that specializes in colour manipulations. It should work along the lines of $(formelement).animate({ color: "#FFFFFF" }, 600); Simply surround the text in a span and fade the span. JQuery will fade the element,

jQuery fade out elements as they scroll off page, fade back as they scroll back on

故事扮演 提交于 2019-11-29 04:19:53
I want elements to fade out as they scroll off the top of the page, and then fade back in as they scroll back onto the page. I wrote some code that works, but I am looking for a more elegant solution. Here is the solution I have working on jsfiddle: http://jsfiddle.net/wmmead/JdbhV/3/ I would like to find a much shorter, more elegant piece of code, but just can't quite work it out. Maybe something with an array and the each() method? If I put a class on the divs instead of an ID, it gets a lot shorter, but then they all fade out at once. I want each box to fade out as it scrolls off the page.

iOS 7 launch image (splash screen) fades out

别等时光非礼了梦想. 提交于 2019-11-29 00:56:33
On iOS 7, launch images fade out instead of disappearing immediately when the app is loaded. Is there any setting to prevent this launch image fade out animation? I need it to disappear immediately just like in the iOS 6 and earlier. Edit for answers: Yes, it is possible to add the splash image as a UIImageView to the top window and hide it after splash fade animation is completed. But this causes a delay of 0.4 seconds which I'm trying to avoid. Alex R. R. I have managed to do that in the AppController. Just place this code right after the creation of the glView UIImage* image = [UIImage

How to make Qt widgets fade in or fade out?

问题 I am trying to fade in and fade out a QLabel or for that matter any QWidget subclass. I have tried with QGraphicsEffect , but unfortunately it works well only on Windows and not on Mac. The only other solution which can work on both Mac & Windows seems to be having my own custom paintEvent where I set the opacity of QPainter and also define a Q_PROPERTY for "opacity" in my derived QLabel and change the opacity through QPropertyAnimation . I am pasting below the relevant code snippet for your

How to apply partial fade in-out in IOS?

I have 2 images. One is in the back of the other. I want to fade-out the top image starting from the left corner. How can I do this? Should I use gradient mask? Here's a technique that will fade out whatever's in a CALayer, from top-left to bottom-right, revealing whatever is underneath the CALayer. Let's say we're going to fade out the layer of a UIImageView called self.fadeView . We'll create a CAGradientLayer and use it as self.fadeView.layer.mask . The gradient will go from alpha=0 (transparent) to alpha=1 (opaque) using four stops: 0, 0, 1, 1. Yes, two zeros and then two ones. When we

I can make an element with an opacity of zero fade in by changing its class to .elementToFadeInAndOut with the following css: .elementToFadeInAndOut { opacity: 1; transition: opacity 2s linear; } Is there a way I can make the element fade out after it fades in by editing css for this same class?

The .fadeOut() method to use visibility property instead of display property

时光怂恿深爱的人放手 提交于 2019-11-28 09:52:26
The .fadeOut() method animates the opacity of the matched elements. Once the opacity reaches 0, the display style property is set to none, so the element no longer affects the layout of the page and same is for fadeIn(). My Question is can they use visibility property so they the element occupy the space in layout of the page and is not just visible? Use jQuery's fadeTo() and then have a callback set the visibility. Example: $('selector').fadeTo(500, 0, function(){ $('selector').css("visibility", "hidden"); }); // duration, opacity, callback http://jsfiddle.net/7HjB6/ Just Overwrite the

How to fade out div slowly, update content, and then fade in div slowly, using jQuery?

杀马特。学长 韩版系。学妹 提交于 2019-11-28 09:49:37
I have a div I want to fade out, update its content, and then fade back in. So far I have tried: $('#myDivID').fadeOut('slow', function() { $('#myDivID').replaceWith("<div id='myDivID'>" + content + "</div>"); $('#myDivID').fadeIn('slow'); }); What happens is that the fade out completes and calls the anonymous callback. So far, so good. The div 's content is replaced correctly, but the fadeIn() effect is immediate — no smooth transition, just a quick, snappy jump to the updated div . Is there a better way to accomplish this? Thanks for your advice. You should do it this way ( this works, is
