Flex :: Handling TextInput Element Width And Styles In AS3

Nov 10, 2009

I made a Form container with few TextInput fields in Flex and I would like to change a style of clicked TextInput element. I managed to do it with MouseEvent.CLICK event listener but it is not what I expected. I would like to change style of TextInput when user try to edit that field. However, I want to change back to 'default' style when user clicks another TextInput field or outside any field. Is there some event listener made specific for such interactions? I have also a question, is it possible to make width of TextInput depending on amount of text? I mean to resize it to width of text inside of it? Text comes from some database and is always different widths...

Flex :: Mobile Application TextInput Width

Jan 19, 2012

I made a simple Flex mobile application to test TextInput fields. I define my View with width=height=100% and use vertical layout. Inside I'm simply placing static TextInput components with width of 100, 200, 300, 400 respectively.I'm also displaying the width of each TextInput in its text property and it shows values which I've defined. What bothers me is the actual width of the TextFields doesn't match the properties of the phone emulator I'm running (Samsung Epic WxH = 480x775) or actual device. For instance the TextInput with width of 400 completely extends past the left and right sides of the device, while it should be contained inside it: it's 400 pixels wide and device has 480 usable pixels available. So do all other TextInputs.

Professional :: Element Width Vs Height

May 1, 2010

I'm writing jsfl script where I'm setting an element width and height. When I go to run the script, my element's width and height are off by what I set it to. For example, I set the width and height to 800, the results I get for width and height are 799.4, 799.0 respectively. I'm not understanding why my element's width and height aren't exactly what I typed in?Btw, I can go into the "size and position" property UI and set them to 800 x 800 and those values stick. It's only when I set the width and height via the element.width and element.height that my values change on me.

Flex :: How Does A Component Know Whether One Of Its Styles Got Changed

Jun 26, 2009

I inherited a custom component from TextField. The component needs to know when any of its styles got changed at runtime via setStyle. How would I do that? It's probably obvious but I couldn't find an event or appropriate method to override.

Flex :: How To Change Component Styles In AS3

Nov 4, 2009

In MXML, there is a Button class which you can instantiate like so:
<mx:Button id="something />
But what if you wanted to dynamically build this in AS3 and add it to the Flex app dynamically, without the use of components (just AS3) and then modify Flex's styles, for example, here you access the Button's properties and set them:

var btn:Button = new Button();
btn.height = 50;
btn.width = 75;
btn.x = 100;
btn.y = 40;

But how would you go about changing the Style, for example:
btn.downSkin = "something";
btn.color = "0xfffff";

I'm sort of starting to lean towards making a flex component in MXMLand than just making it visible true/false, but I like the fact that i create an object in AS3 and then destroy it when I don't need it anymore, than create it again once needed.

Flex :: Custom ItemRenderer Does Not Use Styles Specified

Overridden Styles For Flex Module?

Jun 11, 2009

Can a flex module have styles different from the main application which loads the modules? Meaning... can I have a main set of styles for the application, and separate styles for each module.. with each of them rendering their own styles without disturbing the other at runtime?

My specific case:The main application is developed by me... and the modules are developed by different people who want to contribute to the main application. I want to provide some way for each of the module developers to have their own styles for their modules, without touching the main application or its styles.

Flex :: Current Theme Spark Styles Not Working

May 2, 2011

I am trying to figure out why I am getting an error when using the chromeColor (or other spark style related items):
<s:Button x="10" y="208" label="CALL" width="185" fontWeight="bold" id="bCall" chromeColor="#F90000"/>

This is the error:
The style 'chromeColor' is only supported by type 'spark.components.Button' with the theme(s) 'spark'.

Yet in project - properties, the theme is set to Spark. I also tried setting it to Halo and then back to Spark. Here is my app definition:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="[URL]"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="800" minHeight="600" width="100%" height="100%">

I have seen references that define the mx namespace as "xmlns:mx="library://ns.adobe.com/flex/halo", but then my mx components break (TabNavigator for example) - not sure if that would fix it anyway. I is using flex 4.1 library (I believe the project was originally created when flex builder was at 4.0 if that matters).

No other libraries included.
Project - properties is set to MX+Spark.

Also, if I remove that chromeColor, the project compiles, BUT there are warnings such as: The style 'borderAlpha' is only supported by type 'spark.components.TitleWindow' with the theme(s) 'spark'. Flex Problem (and others - borderColor, cornerRadius, dropShadowVisible).

Css :: Setting Different Chart DataTip Styles In Flex Components

Nov 1, 2011

I have a following issue:My task is to style a datatip for two charts in Flex 4.5.Both charts reside in two different <Group> based components which are added to the <Application>

So after a thorough research here is what I tried to do.First applying a css descending selectors:

#container#chart1 chartClasses|DataTip{
backgroundColor:white;
backgroundAlpha:0.01;

[Code]....

Then I would like to be able to get access to the instance of the CustomDataTip class.But I can't .So currently the only thing I can do is to create a distinct custom datatip renderer class for each chart.That could be fine if you have only a couple of charts you want to style but what can we do if we have many of them?

Flex :: Changing Left / Right Arrow Button Styles For DateChooser?

<mx:DateChooser id="dc" cornerRadius="0" bottom="0" width="100%" allowMultipleSelection="true" allowDisjointSelection="false" styleName="dateChooserGradient" change="fetchDateAgenda(dc.selectedDate)"/>

And the dateChooserGradient:

header-colors: #133c59, #29506c;

headerStyleName: myHeaderStyleName;
weekDayStyleName: myWeekDayStyleName;

arrowColor: #062338;
arrowAlpha: 0.1;

Am facing issue with session timeout. Say for instance, the user logs into the application and he waits for 30 mins (session timeout time) and then tries to get a service through remote object.Ideally speaking, since the session has timeout the user shouldn't be able to hit the remote object, but this is happening the other way round.

Flex :: Keyboard Event Handling?

Jul 31, 2009

I'd like to arrange things so that I have a chain of keyboard event handlers in my flex application, all of whom are queried when key down events occur. Basically, when a visual component is on screen, it is a candidate for handling a key press event. Something like this (clearly this is pseudocode):

<application handles_keys="F5, F6">
<tabGroup>
<tab1 handles_keys="pgup, pgdn">
<control handles_keys="0,1,2,3,4,5,6,7,8,9" />

[code]...

I have a class written that will respond to the key events the way I want it to, so how do I register one or more instances of this class to have the results I want? Also, note that there are some situations where this class should receive events that would ordinarily be handled by a UI component. The TAB key is the main example; I have a few cases where I want my key down event handler to fire even when the focus is on a text field.

Flex :: Http - Handling Redirected URL Within App?

Apr 1, 2010

We have a Flex client and a server that is using the Spring/Blazeds project. After the user logs in and is authenticated, the spring security layer sends a redirect to a new URL which is where our main application is located. However, within the flex client, I'm currently using HTTPService for the initial request and I get the redirected page sent back to me in its entirety. How can I just get the URL so that I can use navigatetourl to get where the app to go where it needs to?
