CALayer as SubLayer Not Visible

由 你。 提交于 2019-12-07 05:25:55
问题 I am trying to built an animated circle which would be drawn clockwise until it becomes complete circle as illustrated in iPhone Core Animation - Drawing a Circle Problem is that CALayer object is not added or build. I tested and saw that it is not accessing my drawInContext:CGContextRef and animatingArc methods. What so far I have done is: In AnimateArc.h @interface AnimateArc : CALayer { CAShapeLayer *circle; } -(void) animatingArc; @end In AnimateArc.m -(void) drawInContext:(CGContextRef

Android 2.2 - how do i set an spinner's alpha property?

由 大憨熊 提交于 2019-12-06 11:10:27
I'm trying to make a spinner totally transparent. In Android 4.0 I can do this setting the alpha property to 0 in the xml layout designer. But when I work with Android 2.2 i can't use that property, Eclipse mark it as an error and tell me that i can't use it. I tried to make it transparent writting this java code: final Spinner cmbCategorias = (Spinner) findViewById(R.id.cmbCategorias); cmbCategorias.getBackground().setAlpha(0); and it works, but the text in the spinner keeps visible. Someone can tell me what can i do?? Thanks Make xml Layout like spinner_textview.xml <?xml version="1.0"

Shared folder with vagrant cause invisible characters appending

问题 I have a few invisible characters (�) that appear at the end of a javascript document that cause the "illegal character" error in FF or Chrome. I saw different topics about this error, but nothing works for me, and i can't see anything wrong in my document (displaying invisible characters, open it with a hexadecimal editor). This is just driving me crazy. I use Vagrant with a nginx web server. The document looks clear in the server too (vi + :set list). Plus, when I get back a clear document

I just try to get Google Invisible ReCaptcha to work after submitting a form. My problem is, the ReCaptcha is NOT invisible, it looks like the "old" recaptcha is popping up. I don't understand why. My site-key is for invisible recaptcha. Please help me. First of all i'm loading the API: <script src='https://www.google.com/recaptcha/api.js?render=explicit&onload=onScriptLoad' async defer></script> My form looks like this: <form method="post" id="contact-form-face" class="clearfix" onsubmit="return false"> <input type="text" required name="name" value="name" onFocus="if (this.value == 'name')

Make DIV invisible in CSS and JavaScript

由 孤人 提交于 2019-12-04 10:22:35
问题 I have managed to make a DIV tag invisible in JavaScript by setting the display to none and the visibility to hidden. It can be achieved with this class also: .invisible { display: none; visibility: hidden; } Display none will ensure the DIV box is empty, and visibility hidden will ensure it isn't visible. The problem with this method is when I have scrollable DIVs or textareas with overflowing content, when you set display: none, some browsers will forget the scroll position for these

setting android button invisible but still having an onClick Listener attached

由 限于喜欢 提交于 2019-12-03 13:53:32
问题 So currently I'm putting an Easter egg inside my app and I want the Button to be invisible, but when clicked(Rick roll). So far I can make it work when I say: Button.setVisibility(view.VISIBLE); Button.setBackgroundColor(Color.TRANSPARENT); and then my onClickListener . The only problem with this is that I have to have text on the Button for it to be clickable. When I take the text out and make it completely invisible then the onClickListener is never called for some reason? Here is my

How to draw to screen in c++?

由 限于喜欢 提交于 2019-12-03 13:34:28
问题 How would I draw something on the screen ? not the console window but the entire screen, preferably with the console minimised. Also, would it show up on a printscreen ? What I want to do is create something like a layer on top of the screen that only me and my aplication are aware of yet still be able to use aplications as usual. Here's an example: Let's say I want 2 yellow squares 5 by 5 pixels in size appearing in the center of the screen on top of all the other applications, unclickable
