Flex :: How To Get X / Y Coordinates Of Caret Inside TextArea Component
Mar 4, 2011
I googled for almost a day to find the answer to my question: [URL]. This almost works (and is a great solution), but the solution doesn't work when I do:
1). Copy and paste multiple-line texts.
2). Write long and scroll the texts.
I also found another working example at: [URL]. (The autocomplete prompt appears when you press ctrl+space right at the caret's position). But an email from its author says he uses monotype fonts to calculate individual character's location. Is there a way to get multi-line input from a textfield?
I am working on flash cs3. I am having a TextArea component in my application.
when i am doing right click on top of the TextArea component, I can able to see the options cut, copy, paste, delete and select all. Now i want to remove those options when i right click on top of the component. how to do this using Flash cs3.

With the Flex 3 SDK you simply needed to set the borderThickness style to 0, or set borderStyle to none. With the Flex 4 SDK ad the Spark theme, this has no effect.
I am putting together a presentation on flex for adobe user group that specialize in coldfusion. In my example I would like to display the text of the cfc being called from the webservice tag in my flex application. Is there a simple way to load the actual text for the cfc instead of the html that coldfusion is passing back to my URLloader variable?
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]...
I am trying to determine the global coordinates of the visible rectangle that is currently rendered on the stage.
Specifically, if a canvas has an explicit height and width and is a child of a panel that has a scrollbar, the scrollbar can "hide" a part of the canvas. ContentToGlobal(x,y) provides the global position of the content at the time, but content coordinates can scroll off the boundaries of the parent panel and continue to give x,y coordinates that are not visible.
Is there a way to determine the viewable rectangle that is not hidden by anything?
I have a text area control on a form that is supposed to accept 5 digit US zip codes. I have assigned the control a keyUp event that checks the number of characters entered until it reaches 5 then forces a new line.
public function forceNewLine(event:KeyboardEvent):void { var maxLineChars:int = 5; var currentLine:int = 1;
[code]...
It works fine except that when the new line is inserted, the cursor moves to the beginning of the textarea. I want it to go to the end.
Now after initialization i want to get the location of my textInput with respect to Application.I tried with with localToGlobal(PointofLocalCoridnate), then it is not giving the correct location of textInput.
I've wrote a custom itemrenderer for a List component (Flex 3.5) which is a VBox with a Label and a TextArea wrapped inside. All works fine so far but I want the TextArea in the first itemrenderer to receive focus so that it instantly becomes editable when tabbing onto the List. Is that possible and if how would I achieve this?
I've already added an event listener that selects the item at index 0 but the textArea in it should also be focussed at that moment _list.addEventListener(FocusEvent.FOCUS_IN, onListFocusIn);
private function onListFocusIn(e:FocusEvent):void { _list.selectedIndex = 0; }
I have two components. One is called "InsideComp" and one is called "OutsideComp". OutsideComp has InsideComp as one piece of its component, and in my main MXML file, I have embedded an instance of OutsideComp. How do I access a public variable of InsideComp within my main MXML file?In Actionscript, I could just do something like:OutsideComp.InsideComp.valToChange = 5; But I dont know how to do it in MXML. I know this is probably an easy question.
I was trying to convert global coordinates to local coordinates of a UIComplenent in my flex project using below code using below code
var gp:Point = new Point(e.stageX,e.stageY); //global point var lp:Point = uic.globalToLocal(gp); //local point
uic is UIComponent in which I have subclass of Sprite for drawing something I have set the sprite's mouseEnabled and mouseChildren to false to not interrupt the mouse event. above code is within uic's mousemove event where I was tracing the gp and lp gp was giving correct value and suprisingly lp was giving negetive values. when I move the move to the top left corner of uic i expect lp to be 0,0 but it is giving the -width of of uic. I broke my head for hours and ended up finding an alternate by using offsets. Infact my original code was much simpler like this which was same issue
var lp:Point = new Point(e.localX,e.localY);
I am not sure what exactly is causing this problem. the workaround had lot of issues and it creating a mess in my rest of the algorithms.Just now I found even more interesting thing (which is actually weird). for some reason I went and create a new lp2
var lp2:Point = new Point(e.localX,e.localY);
now surprisingly it was giving correct values as expected and I went back and changed the code as
var gp:Point = new Point(e.stageX,e.stageY); //global point var lp:Point = uic.globalToLocal(gp); //local point var lp2:Point = new Point(e.localX,e.localY); var lp2:Point = uic.globalToLocal(gp);
now it is expected to have all the lp, lp2 and lp3 variables to be same but weiredly lp two is giving wrong value and lp2 and lp3 were giving correct. I am suspecting using the variable lp has something to do. I am not sure about that but above proves it so right now I am using lp2.
I have a login form with various textInputs and a submit button. If you submit proper login credentials the system unloads the login view and loads the app view. Pretty standard. Unfortunately I've noticed this weird bug where if you hover over one of the textInput boxes with the mouse, then fill the form using only the keyboard (and leave the mouse parked on top of the textInput), and then tab to the submit button and press the space bar, i.e. login via keyboard, the mouse cursor will remain a caret in the new view, no matter what you do (move, click), until you find another textInput to undo the cursor state. I've tried to do all sorts of stuff via CursorManager but nothing seems to do the trick. I've tried dispatching events ROLL_OUT or MOUSE_OUT events to the textInput but that doesn't do the trick either.
I have the strangest issue in Flex!Consider an <mx:TextInput /> with text. This textbox has focus and a nice little caret blinking inside. Now when you press the -> or <- button, the caret moves two positions instead of one! Also when you press the delete button, it removes two characters instead of one.This only occurs in Firefox, but it's not a FF bug because it only happens in my application.
Is there a method to set the caret position within a RichEditableText control? The control's contents can contain errors that the user must fix which are navigated though via Next/Previous buttons, and during the navigation I would like to set the caret cursor to the end of each error within the text.
I am creating a custom component in Flex with extends the BorderContainer class, and I would like to be able to place additional content within the tagset when I use it in my main application, like this:
<components:CustomComponent title="Hello"> <s:Label text="If you have one enter it below:"/> <mx:Spacer height="15" />
[Code]....
This works just fine, except that my component definition had some additional things inside of it, such as a <s:Label/> and styling, which is replaced by the content within the tagset above when I go to use it.
If I do not put anything within the tagset, the content that was originally in the component is not replaced.
Is there a way that I can simply append additional content inside of the component when I go to use it, instead of it being replaced each time?
How do I say an MXML component is inside some package? Well, it's in a different folder... I know how to do it ActionScript... But when I do in MXML I don't declare the package explicitly because I don't know how, and when I call it to my application, it states that The prefix "package" for element "package:Component" is not bound.
But I get a warning from Flex that the binding wouldn't work that way and it doesn't. It works the first time I load up the component but every time I change findFriendsPaginationElement it doesn't reflect on the component. Do you know how I can go about doing this? (making changing a value in the binding variable changes the status of an element inside a component?)
I've developed a component which is a combination of a few items (canvas, labels, etc...) but when I try to bind it to a variable such as: {stationXML.getItemAt(1).AAA.@value}, it doesnt work. Before I combined all the items in a component, they were all in the main MXML file at which time they worked. Not sure if it matters, but the "stationXML" arraycollection variable is declared inside the file "Station.as".
I've created a custom component based on Image component. I want to teach it to respond to change of binded variable. E.g. if main class has a variable balance, I want the component to change image in case balance = 100 one image, in case balance = 50 to another.[code]...
I have an Item Renderer having HBox. Now I want to add child in that HBox from my application file using addChild method. Any way around for the same. I am not able to access the properties of HBox inside the item renderer.
I have a component in AIR like so:[code]The 2 alerts both work. however nothing happens when you click the new window link.all 3 links works when in a real browser so I know its ok.Is there just no support for window.open in the AIR HTML component? or is this a bug?Is there a work around?
We have a TextArea that is created dynamically reading in XML data with the textFormat set to Arial font as the default. When we publish it the font tag for a subscript and superscript fonts is not displaying even though we have embedded the fonts. It displays properly if the font is installed.
The scroll policy for the textArea component appears to be "auto", and that works just fine.However, I want to be able to turn it off in certain situations, i.e., not have the scroll bar appear.I do the following which I thought would turn it off but the scroll bar still shows up.
