In flex, how to have 'justify' text align option - apache-flex

How to make text in flex justified (text-align option)

If I understand you correctly, you want the text of your paragraph to be flush on both the right and left sides, which means you want to set the textAlign style to be TextAlign.JUSTIFY (which is really just a static member that maps to the string 'justify'.) Hope that helps.

Short questions, short answer:
myLabel.setStyle('textAlign', 'left');

How to add a default Text at the start of the multiline React Native TextInput

I'm trying to implement the replying input in React Native and I'd like to have a possibility to render the person name I want to reply to at the start of my reply text. I attached the example image. This Input will be multiline and it's important because I was thinking about adding some padding for my reply TextInput and just absolutely position the Person Name text at the padded space.
It looks like a possible solution but:
How to do it if we have multiline Text? if we add some padding for the TextInput it will affect all lines when I need only the first one
The person name text could have various width so the padding value shouldn't be hardcoded. I think it could be solved by just rendering the Person name text first, calculating its width, and the set the padding for the TextInput but even in this case we'll face the issue 1)
Is it possible to achieve this feature somehow?
Thanks for any help!
You could have a nested style.
<Text style={styles.username}>#Rosemary#9234<Text style={styles.body}>I agree with you!</Text></Text>

How do I truncate a Flex StyleableTextField after two lines?

In my Flex 4.5 mobile app, I have an actionScript item renderer (that derives from Flex's LabelItemRenderer). I want to fit in exactly 2 lines of text, and then truncate the rest. The width and height of the label are fixed and known statically.
How can I do this? The StyleableTextField.truncateToFit() method only works for one line of text.
I've set wordWrap = true, so the text now flows into the second line - but I need to truncate the text if it doesn't fit in two lines.
I need it to show all the text if there is only one line. (in both cases the label should be vertically middle-aligned in my renderer)
I know how to override layoutContents to do sizing and positioning etc of the StyleableTextField. So I'm looking specifically for ideas to implement custom text truncation with the StyleableTextField).
Any ideas?
Unless you're using something specific to the StyleableTextField try the s:Label. It has a property maxDisplayedLines which you could set to 2 and it will handle the truncation.

Centering item renderers in a HorizontalList

I am trying to center itemRenderers in a horizontal list if the number of items in the list is less than the maximum visible number. Has anyone found a good way to do this?
See an illustration of what I mean if it is hard to picture.
Thanks!
Override the measure() method - I've writen a blog entry here: http://flexmonkey.blogspot.com/2010/05/centre-aligned-horizontallist-in-flex.html

One solution that comes to mind would be to add invisible renderers to achieve the same centering.
You might want to consider using a horizontal box or "Hbox" instead of a horizontal list component. This will allow you to use the horizontal align property to set center. If not, simply extend the horizontal list component to accept a center align property, and copy it from the hbox to your new extended component.
Would paddingRight or paddingLeft accomplish what you're looking for? If you combine it with setting the columnWidth and the columnCount, that would allow you to adjust where the items first appear.

how to wordwrap in flex tree node

I have a Tree object in my Flex code. It's width is 100%, and it is contained by a Panel with width=200. I am using a custom itemrenderer that extends TreeItemRenderer.
I need the text in each node to word wrap if it's too big (as happens often). I have tried
label.wordWrap = true;
in my item renderer without any luck. Any other suggestions?
If 'label' is an instance of the Label component, you won't be able to get it to wrap, no matter what you do, as the Label component doesn't support wrapping. Or, rather, is meant to be used only for single-line text.
If you are using a Label component, try using a Text component, instead. It's meant to display multi-line text.
With the default TreeItemRenderer you just need to set two properties on your Tree to enable wordWrap:
tree.variableRowHeight = true;
tree.wordWrap = true;
Enjoy.
What is the height that is set on the label? Is there enough room for the text to go vertically?
try setting the label width to a constant width. If your not able to do this because it needs to be dynamic then you need to override the update functions and set the width of the label then. The problem is the label hasn't calculated the actual 100% width at the time of rendering so it doesnt know it has to warp or not.
Dont Use Label. Use ' mx:Text width=" 100%" ' ( Text with 100% width) and it will wrap on its own.

Ghost/translucent caption inside text input?

First, what does one call the ghost caption that appears in a text edit if that edit has no real text?
Second, has anyone invented that particular wheel for Flex text components?
Thanks
It's called a Watermark.
I'm not an expert on Flex but here is one example:
