Flex :: 3 - Property "editable" Of TextArea Control
May 28, 2010
I'm having issues with the property "editable" of textArea control. I have a component: OrderView.mxml and it's associated data class OrderViewData.as. Orderview.mxml is inside a viewStack to enable navigation from a component to another. In this particular case, OrderView.mxml is called by another component: SearchResult.mxml. I can thus navigate from SearchResult.mxml to OrderView.mxml, and back to SearchResult.mxml... OrderView.mxml has textArea and textInput control, that have to be editable or nonEditable depending on the property var isEditable:Boolean from OrderViewData.as.
When the application is launched, isEditable = true. So, all textInput and textArea controls are editable the first time the user gets to OrderView.mxml. When the user clicks on the button order from OrderView.mxml, isEditable = false. When the user goes back to SearchResult.mxml, isEditable = true (again) --> Until here, everything works fine. The thing is: when the user goes back to OrderView.mxml for the second time (and beyond), even if the property isEditable = true, textArea controls are still non editable... But the textInput controls are editable!
I am simply wanting to stop a user entering carriage returns in a TextArea. I have been experimenting with the 'restrict' property in the TextArea but cant seem to work it out.I have the following code:
<mx:Canvas id="cvs1" label="Panel 1" width="100%" height="100%" creationComplete"addEvtListnerOnPlaceText()" backgroundColor="#FFFFFF"> <mx:TextArea id="txtP1T1" x="10" y="176" text="{placeName}" width="210" textAlign="center" color="#DC0000" restrict="this is where I need some help"/> </mx:Canvas>
I've now managed to get something working:
private function addEvtListnerOnPlaceText():void{ txtP1T1.addEventListener(KeyboardEvent.KEY_DOWN, onKeyEventDown); txtP1T1.addEventListener(KeyboardEvent.KEY_UP, onKeyEventUp);
[code]....
The only issue now is that if you hold return down, it clears the first carriage return and then keeps adding as long as you hold it down. I need a way to stop this happening without just losing focus on the text area.
How do you scroll an editable TextArea (Flex Hero) on a touch device? I am referring to the situation where the text does not fit in the TextArea height.When I try to tap and drag the text gets selected and not scrolled... Am I missing a something here? I am using verticalScrollPolicy = on (also tried auto).I am testing the code in the Blackberry Playbook simulator (my targeted device for my app).
I have a TextArea component in a flash document, and this TextArea is loading text from a .txt file.
However, when you're viewing the textarea in a webpage, you can not only select the text that has been loaded into the textarea, but you can also delete the text written there, like it's a word document or something.
I am developing a Flex based window application. In that I have used a textArea, Now when I type some characters like ctrl+b, ctrl+e or ctrl+q, it shows some square characters in text area, I think these are some unicode characters but why these are being entered.
Unlike in simple textArea control on adobe example when I presses these key combination, there is nothing being entered, so why this only with me.
in flex,I have a textarea control i like to select some text in textarea. when mouse releases then selected text will be hilighted to GREEN RECTANGLE as sprite.
I am writing a flex application that involves modifying a textarea very frequently. I have encountered issues with the textarea sometimes not displaying my modifications.[code]When you run the above code in a flex project, it should repeatedly print, character by character, the sentence "The big brown fox jumps over the lazy dog.". But, if you are typing into the textarea at the same time, you will notice the text the timer prints is distorted.I am really curious as to why this happens. The single-threaded nature of flex and disabling user input for the textarea when I make modifications should prevent this from happening, but for some reason this doesn't seem to be working.I must note too that, when running the timer at larger intervals (around 100ms) it seems to work perfectly, so I am tempted to think it's some kind of synchronization issue in the internals of the flex framework.
I have an app that has text appended to a TextArea (TA). It automatically scrolls to keep the recent line added in view. Over time, this could be a lot. Do I have to worry about this? Is there an upper limit? And, if so, how can I prune the oldest lines of text?
I have a class which inherit from ComboBox .i want to implement a function to control the position of the cursor.Any builtin function?

Latest_News_Display is under the Latest_News state. I want to set Latest_News_Display's x property even if the currentState is set to Intro. However, when I try to use Latest_News.Latest_News_Display.x = 10,it returns an error that says 1120: Access of undefined property Latest_News
I have created a textArea element but cannot display my HTML content. If I just display regular text it works or if I change the textArea element to a RichEditableText element it works fine. Since this is for a mobile app I would prefer to use the textArea element as recommended by Adobe.Here is the MXML code for the textArea. All I get is the border and no content displayed.
I am trying to: 1) create a dynamic property 2) bind that property to a label This works great for "sealed properties", but for dynamic properties there doesn't appear to be any event triggered. Are dynamic properties implicityly not bindable?
var myObj:MyType = new MyType(); // MyType is dynamic myObj["myDynamicPropertyName"] = "initialized"; BindingUtils.bindProperty(myLabel, "data", myObj, repeatedLabel.name); // myLabel now displays "initialized" myObj["myDynamicPropertyName"] = "changed"; // myLabel still displays "initialized", it should say "changed" !!!
What's the difference between selectedChild property and selectedIndex property? I read the documentation, both seems to be setting currect active accordion. selectedChild can be only used in actionscript, but other than this, what's the difference?
I have a number of textarea controls which display data retireved through XMLConnector / PHP / dataset. How can I change the font size (or colour) using actionscript 2.0 in a Flash textarea control?
the second instruction just does not work, and the textarea scrolls to the beginning (as a consequence of the first assignment). Has anyone else run into this and have you come up with any workaround?
This only happens in AIR, not FP, and only with TextArea, not with a plain input text.
Users need to be able to paste the contents of an Excel spreadsheet into a grid in my flex application. I have implemented this using a TextArea with a change event handler that parses the text the the user pastes - splitting it up by newlines and tabs - and adding it to the ArrayCollection that is bound to the grid. However, it makes no sense for users to be able to manually enter text into the TextArea. How can I prevent them from doing so?
I realize that ItemFocusIn is somehow only applicable to editable datagrids in flex,nevertheless I want to fire an event anytime the user selects a new row in a non-editable datagrid. I have successfully used the CLICK event, but this event is not fired when the user uses the keyboard to select a different row in the datagrid. What do I have to do to cause an event to fire whenever the currently highlighted row in the datagrid changes, regardless of weather it was changed by the mouse or by the keyboard?
All i have a flex editable datagrid. By default if i press the left navigation arrow key , it moves to the left but not to the next cell. I would like to override the keydown event such that if the left navigation arrow key is pressed down i set the focus to the next cell on the left.
In short the user needs to be able to navigate using the keyboard through the cells using just like in excel(currently the arrow keys move between characters within a cell).
I'm trying to override the default handling of the 'up' and 'down' keys for an editable list, such that when they are pressed a list entry that is being edited behaves as if the escape key has been pressed, but the 'selected item bar' moves up or down.
Here is my (simplified) component: <?xml version="1.0" encoding="utf-8"?> <mx:List xmlns:mx="[URL]" enabled="true" width="100%" height="100%" creationComplete="initialise()" editable="true" [Code] .....
For some reason this doesn't work: if a row is being edited, the first 'up' (or down) keypress ends the edit and moves the bar. Further up or down keypresses have no effect, but if you click somewhere near the list it does start working. This makes me think it is a focus issue. Weirdly, if you hit escape the edit finishes and you can move up and down correctly. If the 'callLater' line is uncommented to try and make the list retain focus, the bar initially moves in the direction of the keypress but then moves back again and re-edits the original line!
I have a datagrid in flex and i am making the datagrid as editable. I can able to edit it and enter the values. so far so good. Now my requirement was, i want to restrict the editable datagrid cell to some max chars like 10. I mean to say maxChars = 10, i want to restrict like this & i want to implement like this.
I'm using a Flex datagrid where only 1 rowItem is editable. All the other row items are non editable. When I edit the value of the row, and press ENTER or TAB the focus is send to the next editable item in the datagrid. In this case the editable field on the next datagrid row.
I don't want this standard behaviour... I don't want the focus to be processed to the next editable item. Since the data is saved instant, it's quite strange that the focus is given to the next field. The focus has to be remained on the item that was edited.
I have an editable datagrid, whenever I make a change it automatically gets saved. How can I disable this? So the changes gets saved only when I click on an external save button.
I have an editable datagrid. If sorting is applied by clicking any header of datagrid, it works fine. But after that, if data values are changed in any row of datagrid, sorting is applied automatically. How to prevent from this behaviour? i.e. sorting should only be applied if user clicks on any header of datagrid and sorting should not be applied when user modifies data in grid.
I have an advanced datagrid, but I want users to allow to copy some lines they want. when I use the property editable they are allowed to select the text they need, but they also are allowed to edit this. How can I prevent that?
I want users to be able to select any text in the datagrid, but they are not allowed to change the value of the grid. They should only be allowed to select and copy (ctrl + c).

I have multiple tab loops, where I enable/disable the loops as needed to control the tabbing experience. I'm attempting to set control the tabbing with the tabChildren property on the Movieclip or Sprite containers I have by setting their tabChildren property to true/false. I am trying to set up tabbing that has three distinct tab loops (three different containers), each with their own internal Sprites/Movieclips that have their tabIndex properties set as needed. I am able to properly set tabChildren to false, and back to true. But with the component, once I set it to false, I can't set it to true again.
Tab loop 1: main content (a loaded SWF file)
Tab loop 2: nav bar (previous & back buttons to load different SWFS, and a Help button)
Tab loop 3: a help pop-up window (a Sprite container) with a scrollPane component used to show scrolling content
Things seem to work fine without the ScrollPane component involved in the mix.Have others experienced this inability to control tabChildren like this? And with regards to using components? I am not using the FocusManager class in any capacity, and believe that it only applies to the components (unless I created my own components and implemented IFocusManager, which I haven't).
