Flex :: Prevent Copy Event In TextArea With Scroll?
Feb 14, 2012
I would like to disable copy event in the TextArea I'm using. To achieve so I added the following code block:
function initTA(){
var tf:IUITextField = body.mx_internal::getTextField();
tf.enabled = false;
}
<mx:TextArea id="body" creationComplete="initTA()" .../>
This is working fine unless the text area has lots of text inside in which case a scroll bar appears. After the scroll bar is being used by the user, the text area stopped blocking the copy event.
By the way, I am using text area for display purposes since I use rich text area format.
I have a TextArea that I don't ever want to be scrolled. When scrolling within the application that holds this TextArea, however, the scrolling stops as soon as the mouse ends up over the TextArea.
Is there any way to pass the scroll event to the application, or tell the TextArea to not claim the event?
If you have two text areas with different styles (fontFamily, weight, color etc) and you copy text from one to the other it also copies the style from the originating text area. Is there any slick way to prevent that?
Here is a sample of code that will illustrate the problem. Type some text in the top box and some text in the bottom, then copy some characters from the top box to the bottom. I'm not using htmltext.[code]...
I have a TextArea that shows the conversation from selected chat room. For valueCommit event I use: verticalScrollPosition = maxVerticalScrollPosition; And it works fine scrolling text to the bottom. However in one case it doesn't work as expected. There's verylittle text, so TextArea has no scrollbar and then I put a lot of text and a scrollbar is necessary. The text is scrolled almost to the bottom (still a few lines need to be scrolled down). I am pretty sure it gets maxVerticalScrollPosition as if there was no scrollbar. So the question is how can I wait with updating verticalScrollPosition with respect to TextArea's new size (that is now with a scrollbar). I tried calling validateSize and other methods that start with 'validate' but unfortunately with no luck. I also tried the old trick of putting caret at the end of text. So the TextArea's scrollbar makes a difference when getting maxVerticalScrollPosition and I need to update verticalScrollPosition once all measurements are done. I forgot to mention. I use htmlText.
Below is the code for a simple Flex actionscript project. A sprite is partially covering a hyperlink. What's happening is that when you hover over the sprite, if you're also hovering over the hyperlink, the hyperlink is activated. I want to prevent that. I want the hyperlink to be activated only when the mouse hovers over it -- but not when the mouse hovers over the sprite which covers it.
I have a weird issue (weird because it is specific to one component) with applicationComplete in a fairly simple application. All the UI components are declared in MXML. I can access them all in applicationComplete, but not a spark.components.TextArea component, named taStatus here; it is null in the handler.[code]...
Every time a user takes a new line (i.e each time they press the return/enter key) when typing in a textArea, I would like the textArea to dispatch an event.I can then listen for this event and then carry out some processing on the textArea's contents.
I need the ability to create a TextArea entity in a constrained area (i.e., it is located at x and y and is w pixels wide and h pixels high and have that never change.), containing a proportional width font. As such, no 'num char entry limit' strategy is feasible. They need to be able to fill the entire area, and if that means 1,000 period '.' characters, or 200 '#' or "W' characters, then so be it.
The two lines following this one consist of 30 periods followed by 30 Ws. .............................. WWWWWWWWWWWWWWWWWWWWWWWWWWWWWW
I cannot limit a user to 30 characters. They need to be limited by using a TextArea that will let itself be filled until full, and then refuse further input until space is created by removing existing content. I then need to print that TextArea _as rendered on the user's screen_. Any 'scrolled' lines would be unprintable, and therefore the user's entry must be limited BEFORE any scrolling occurs, or contrariwise, when scrolling occurs, the last entered content would need to be removed and the entity forced to un-scroll. I can program this. It won't be elegant, and in fact will be quite stupid, as any programming where a change event is called with each keystroke or paste and then conditions tested is inefficient, wasteful, and well.
I'm using Flex 4.5.1 with AIR 2.7 (and Flash Builder 4.5.1) to build an app for the Blackberry Playbook.
The app has a large textarea that needs to be resized when the soft keyboard shows up. I am able to hook into the soft keyboard events and do things there.
Now, I want to resize the textarea to fit the remaining part of the screen when the keyboard shows up. I know the current and destination size and want to use a smooth animation to show the textarea resizing. (I can't already set the height and can see the textarea being correctly resized in the keyboard_activating event - but I want to do it through an animation). I've tried using the Animate class, the spark.effects.Move class and none of them seem to work in this case. They seem to run the animation but the screen does not get refreshed!
In the code below, image01.gif is 'higher' than the textArea readingPane(ie image01.height > readingPane.height). My problem is that I cannot srcoll the image. Is it possible? If so,how?
import fl.controls.TextArea; var readingPane:TextArea; var htmlString:String = <img src='http://localhost/strategist/images/image0.gif' hspace =
I created a custom scroll bar, you can see it here [URL] My scroll dragger is not working. First, I have removed all of my code except my scroll bar code and my scroll dragger still doesn't work. If I remove all of my stage elements and leave my custom scroll bar on the stage, the scroll dragger works. If I try to add an object back onto the stage the scroll dragger stops working. It doesn't seem to matter what object I add back to the stage. There are no compile errors or output errors to fix. I even created a new fla and I am getting the same issue. Adding movie clips from the library to the stage prevents the dragger from working. I am really puzzled by this. I am using Flash CS3. I have added a zip file of my fla.
I want to make a dynamic textarea with loaded text from an external textfile, and then I want custom made arrow buttons to start scrolling the loaded text on mouseover (not click) andt stop scrolling on mouseout. Ala like in this webpage[url]...
The part with the loaded text is fine, but I can't manage to script the arrow buttons to do what I've just described. Even though I have searched the Internet for recipes I just find how to scroll loaded text on click or with a scrollbar
Now, when I click on the button in the area where the movieclip is it will register this movieclip as event.target. I would like to make the button the event.target regardless where I click and prevent flash from registering the movieclip inside the button as the target.
I have a movieclip containg several containers with other objects attached to them. Those containers have different levels of nesting. Now I want to add an EventListener to the top-level MovieClip and the called function uses attributes of this MovieClip. Because of that I cannot just retrieve the MovieClip by saying e.target.parent but have to stop the propagation. I know there is a stopPropagation() method but I don't really get how (and when) to use it.
If I have sth like this: function myResponse(e:Event):void { //Things happening } myMC.addEventListener(MouseEvent.CLICK, myResponse);
In my game, if the ball hits the winBox, you get a Win message. The problem is that the ball bounces, and it might hit the box repeatedly. How can I prevent the message from happening twice per session?
if (simContacts.isCurrentContact(winBox,gameBall)) { // Won.
Here is the code I get when I do a motion tween in cs4 and select Copy Motion as AS3. I want to add this event but I don't know where to add it? WANT TO ADD THIS EVENT TO HE CODE BELOW: MotonEvent.MOTION_END.
I have an AS3 movieclip with a button. Both the movieclip and button needs a click event but when I click the button it also fires the parent movieclip's event handler.
I'm trying to make a vieport in which you can pan by dragging the background image around. Here is what I've done: [URL] Note that I've hidden the mouse cursor and replaced it with 2 custom ones. The problem is, the event attached to the background, which is a touch event, fires even when the mouse is over a sprite/movieclip (the monkey or the stats) that's in front of that background. And the stats isn't even in the gameLayer (where the monkey and the bg and the mouse cursors are). Try to drag the stats around, and see that the background and everything else pans with it (this is unwanted). Also, I need to remove the custom cursor and show the regular cursor whenever the mouse is NOT on the background (i.e. when it's on the monkey or stats or any new sprites I may/will have in the future).
if I type any thing in textarea, then this colorize() function is called twice. How can I stop this one that both event should not be triggered together.
A web channel streaming service streams to a certain IP range, it only checks the IP in example.com/cmd.php?id=xxx (channel number) and outputs an rtmpe stream URL, nothing else.How do I trick it to get my local URL instead of the one on their server? I have considered squid proxy, but is there some way to do it with a firefox plugin or greasemonkey script?
Edit:I will try to specify:It's a streaming service from an ISP and cable provider. They stream for free to people on their IP's. On their webtv page, which is called webtv.example.com, there is a flash player. If you are not on an IP from their ISP, you can't stream anything but the test channel.When you try to change channel via. javescript:videoplayer_changechannel(xxx) it makes this HTTP request:
[URL]
If you are on one of their IP's you will get an RTMP URL, like this:
[URL]
This is what the flash player requests, and if it get's this response it load the channel requested. There is no HTML on the php page, just the URL. Note that the rtmp URL is static.If you are not on one of their IP's it will return a random sentence (something stupid, the programmers having fun).I wan't to trick the flash player into getting the right value, even though it's not on one of the ISP's IP's.
Our users want to copy and paste some rows from an Excel spreadsheet, or a chart generated in Excel, into a text box within a Flex application.It would be ok for it not to be fully functional, like an ActiveX object, embedded in the flex app. If it converted it to a static image, that would be fine. But I don't know of any Flex component that supports this.
Unfortunately, when I start placing text in this text area. Either through code or user input, the text will be placed on a new line after about 80-100 pixels. Yet I want it to start a new line after 320 pixels (it's length).
