I have a TextArea in a mobile application that I want to force invalidation on a certain event. So far I can do this:
myTextArea.width = myTextArea.width + 1;
I know it works because the text area updates correctly.
I've tried to do it "correctly" using the following:
testing.invalidateProperties();
testing.invalidateDisplayList();
testing.invalidateSize();
testing.validateNow();
parentGroup.invalidateProperties();
parentGroup.invalidateDisplayList();
parentGroup.invalidateSize();
parentGroup.validateNow();
None of the previous code works.
The TextArea is using the StageTextAreaSkin.
UPDATE
This seems to work as well as setting the width but is also a hack and also doesn't sync with the rest of the components:
testing.skin.styleChanged("anything");
The only way I've found to force a validation is to call myTextArea.setStyle("anything_here") or myTextArea.skin.setStyle("anything_here"). Note, it may be the fault of the skin, it is a mobile spark skin from the SDK (not my own creation). Better answers are appreciated.

I am trying to use Autoresize on some of my View Controllers Auto Layout on others. Everything looks fine on all device sizes when I use the "View As:" tool in Storyboards. There are no overlaps and everything fits nicely. However, I have Auto Layout Warnings:
Why am I getting these warnings if nothing is clipping or overlapping? And how do I get rid of them?
Well I think you don't need to do any special steps, just try adding auto-layout margins using (control + actions told) storyboard and xCode will automatically handles them separately.
Other controllers that you have made ready using Auto-resizing would not be effected by this.
And new controller you made ready with auto-layout would work fine as well.
Hope this would work out for you.
For reference adding 2 screenshots (both are from same xCode project) for you to be clear of that what I am trying to say...
if you don't want to use auto layout just disable it.
select ViewController in storybored,go to file inspecter -> locate the Interface Builder Document section.uncheck use Autolayout.
I'm creating an app in Angular 6 and I want to change all the scrollbars to a custom one. I'm aiming for something similar to the Mac OS scrollbar;
Transparent
Over the content
Shows on mouse over
I want a method that will replace all and any scrollbar that will appear in the app to this custom one without altering the html.
I've been looking for an Angular/Typescript plugin to do this but each one I found is suggesting that I wrap my content in it's related selector. Which is not something I want to do. Or am I not understanding how to use this?
This one plugin I'm looking at: https://www.npmjs.com/package/ngx-perfect-scrollbar
Is there a way to use this plugin without wrapping my content with <perfect-scrollbar>?
Sorry, I'm very new to Angular :(
I was also looking into Custom CSS scrollbars but that only works for webkit browsers.
just use this :
const ps = new PerfectScrollbar('.scroll-container');
and set scroll-container class on all the elements that need scroll
A recurring problem with modern web design can be summed up as "too much sh** all over the place". There're two problems with this: one, it takes up memory and takes longer to load, and two, it visually clutters the webpage.
If I just wanted to solve the second problem, I wouldn't need help. JavaScript can delete DOM nodes and CSS can hide them, so there're already a few visible ways to simply hide parts of a webpage. What I want to do is solve the first problem - make a webpage load faster by not loading certain elements.
I'm pretty sure it's impossible to selectively download certain parts of an HTML file. But once the source is downloaded, the browser doesn't have to actually parse and display all of it, does it?
Of course, if this is done after it's already been parsed and displayed, it would be pointless. So I need a way to tell Chrome what to do before it begins parsing the HTML. Is this possible, and do you think it would significantly reduce load time/memory usage?
Yeah, unfortunately Ive never seen a way of changing the html before Chrome renders it.
But as far as blocking things that that page gets to display then Id recommend just using AdBlock https://chrome.google.com/webstore/detail/gighmmpiobklfepjocnamgkkbiglidom
AdBlock can be used to stop resources (js,images,css,xmlhttprequest) from ever being downloaded (it blocks them in the background using the webRequest api) and can also hide elements using css...its rather effective (just remember to select advanced options in its option page and then when you click the AdBlock button you get "Show the resource list"). Also installing Flashblock can help...or disable plugins in Chromes settings, doing this will make them not load but will still show on the page and then you can make them load.
Totally possible! Meet the newest Chrome API: webRequest, finalized in the current version of Chrome - 17.
Docs for webRequest: http://code.google.com/chrome/extensions/webRequest.html#event-onBeforeRequest
I'm trying to think of a solid way to do this... one suggestion I have is using the 'sub_frame' filter, and watching if it's a like/tweet/social button url
You could also block known analytics stuff... and the list goes on! Have fun! Do you have an email list I can sub to for when you launch? If not, get one and drop me a comment!
(From the comments, here is how a innerHTML hack could work)
//This modLoop constantly peers into and modifies the innerHTML in attempt to modify the html before it's fully processed.
var modLoop = function modLoop(){
var html = document.documentElement.innerHTML
//modify the page html before it's processed!
//like: html = html.replace('//google'sCDN.com/jquery/1.7.1/', chrome.extension.getURL('localjQuery.1.7.1.js'));
//I just pulled that ^ out of nowhere, you'll want to put careful thought into it.
//Then, mod the innerHTML:
document.documentElement.innerHTML = html;
setTimeout(modLoop, 1);
};
var starter = function starter(){
if (document.documentElement.innerHTML && document.documentElement.innerHTML.lengh > 0) {
modLoop();
} else {
setTimeout(starter, 1);
}
};
starter();
I've been asked to fix a few bugs on a website, and one of them is throwing me for a loop. Due to the style layout of this particular site, when a user selects and copies text from a specified area, they copy rich text data which if pasted into a rich text editor, results in a large black text on black-background blob.
Ideally, I would like to strip all style data, or somehow enable plain text copying on a particular set of data.
Is this possible? Or would I have to resort to something like a a Flash applet like what GitHub uses for Git URLs?
If you're happy with using JavaScript to solve the problem you can capture the "oncopy" events (credit to #FirstZero) on the elements you wish to restyle, and then restyle the element using JavaScript and style it back again after a timeout.
If you are okay using jQuery you can use JavaScript similar to the following:
$('p').bind(
'copy',
function(e) {
var copyElem= $(e.target);
var defaultColor = copyElem.css('color');
copyElem.css('color', 'pink'); // Change the color to pink for copy
window.setTimeout(
function() {copyElem.css('color', defaultColor);}, // Change it back
1
);
}
);
(Try it out in jsFiddle)
Note that this would be neater if there existed an onaftercopy event, but unfortunately there doesn't seem to.
I've only tested the above solution in Chrome, but it should work in Firefox (since 3.0), latest versions of Chrome and Safari, and in Internet Explorer. It will probably not work in Opera.
Many many years ago, I made a custom form that replicated the look of a menu on a video game. At the time, Firefox didn't allow many form UI widgets (Firefox 2.something?) to be styled with CSS. Apparently in the last few years that has changed.
What I wound up doing to resolve this problem was creating a very large input text-box with the content passed in via the value="" attribute. (<input type="text", not <textarea)
Despite the ability to style input boxes and their content, this information is not retained when copying the text itself. So I completely side-stepped the issue, and the fixes are live!
It was quite a bit simpler too, absolutely no-JS required.
This is more of a best practices question rater than something technical.
I'm working on a mobile app using the Flex 4.5 SDK and I'm trying to figure out the best way to handle notification windows. In most cases these windows will be alerting the user to when something goes wrong. Ex: bad login, no data, cannot resolve server.
I'm using a singleton design pattern, I have a Requests class that handles server calls. Most popups will be originating from this class (IOErrorEvents from my loader being used to access the API). Since this class is a singleton and is used from all Views inside the app it is not aware of applications current view. I'm also not sure having this class keep track of the current view and having it push popups on top of it would be best practice.
I'm hoping that I can use PopUpManager to keep track of where to add popups and what popups are currently on the stage. Though all examples I've seen online about this show static Components being used in a views Declarations tag.
I'm really just looking for any examples or input on how you would solve this problem. Any help would be greatly appreciated!
I had the same problem, and sorted it by making an Alert popup component that you can call from anywhere in the code base, and it will pop up in the currently active window. It also has an always visible scrollbar text area which is handy

It works for a view navigator application, but if your using a tabbed navigator application, you can add a call for that, or simply change the code to
mainTabbedNavigator = FlexGlobals.topLevelApplication.tabbedNavigator;
currentTab = mainTabbedNavigator.selectedNavigator as ViewNavigator;
