In Flex, is there an easy way to change the size of a Checkbox? I want to make the checkbox bigger, but the label beside it the same font size. Thanks!
I've used scaleX and scaleY. I think the syntax is scaleX="1.5" scaleY="1.5" to make it 50% larger.
I would imagine you could programatically skin the checkbox but ive never done it. Just increase the w and h passed in from the updateDisplayList(w:Number, h:Number) function when creating a programmatic skin.
Another option, albiet rather hacky, would be to make a custom control. A canvas, a label for the checkbox text and an image for the actual "check". Click on the image, if its checked it shows your unchecked image and vice versa.

In a chrome extension (so feel free to make Chrome-specific suggestions), I'd like to make a textarea and a button on a single row. The textarea has a defined height (in rows). The button should be the same height as the textarea. Ideally some attribute or setting allows me to manually determine the width of the button versus the width of the textarea. Ideally this is just a css/html solution, not javascript if I can avoid it.
You will need to use flex box with
{ align-items:stretch }

I am trying to set the text background of the JavaFx label text as green using the following CSS
label.setStyle("-fx-background-color:rgba(85, 255, 68,0.7););
And the unhighlight using the following
label.setStyle("-fx-background-color:rgba(0,0,255,0);");
However these does not work most of the times when it has to be done back to back.
Is there any way to set the style without using CSS i.e. using JavaFx API itself. I found label.textFill(Paint p) for text color but nothing for background colour i.e. the color of the label itself.

For some styles (such as the text fill) yes. For background colors, background images, borders, etc API methods will not be available until JavaFX 8 is released (see Public API for Region backgrounds and borders in the JavaFX issue tracker for more information - anybody can sign up for access).

If you just highlight a label and then unhighlight it again without using something like a PauseTransition to give the user some time to see the highlighted label, then, from the user's perspective nothing is going to happen as all the user will see is an unhighlighted label.
Not sure of your use case, but if you only want to highlight part of the text in a label or let the user highlight the text with a mouse, then you can use a TextField with editable set to false.
Possible Workaround
If the Java 8 preview does not work for you and you are experiencing errors due do bugs in the JavaFX CSS processing, then try placing a Pane then a label inside a StackPane. Set the background color of the Pane to label.setStyle("-fx-background-color:rgba(85, 255, 68,0.7);); Bind the Pane's preferred width and height to the Label's width and height and toggle setVisible on the Pane as appropriate.
Finally I found the workarround. I had to give a PauseTransition to give the system some time between unhighlight and highlight. CSS showed effect only after the pausetransaction if the labels were already highlighted. I think it may be a bug. I will file a jira. The duration of paustransition may be as low as 1 milisecond so that there is not lag from the user's point of view.
I want to set background color for specified range of text in UITextField. So Itried using setSelection. But it need focus. Any one please help. Can we set selection without focus.
Use UITextField.alwaysShowSelection property.
I'm trying to create a custom tab navigator that has to look like this http://www.freeimagehosting.net/uploads/b470d024c4.jpg.
Also, when there's a rollover, the borders of the arrow have to be in blue (like the label in the current tab).
For that purpose, I've created a custom component: a hbox containing a label and a canvas with 3 images inside (for the arrow tip that has to change depending on the currentState).
Then, I thought of overlapping the components in order to get the blue highlight color (ex: arrow button 3 is over arrow button 4. The image of the arrow tip in button 3 will be transparent outside the arrow, so that we can see the black color of the following button).
I'm now trying to position the components inside the canvas ... but I cannot.
After the creationComplete event, I assign the label text and I was calculating the coordonates of the component but it doesn't take into account the label width... -_-'
Any ideas?
Thanks. Regards,

Read up on the Flex Component LifeCycle. You should be positioning and sizing your child components in the updateDisplayList() method; not in a creationComplete handler.
You should assign the label text in either commitProperties or createChildren depending upon when you know what it is.
If you want to share some code, we may be able to hone in on the exact problem. If you run code like this:
myLabel.text = 'Blahblahblahblah';
trace(myLabel.width);
I would expect that the width has not changed to reflect the new text because the myLabel has not gone through it's own component lifecycle steps yet.
how can i get a title window with all rounded courners, so that i may make it whole round or circular shape ?
i want shape like circle..
set the property: cornerRadius
default is 4
A couple of possible approaches:
If you are using Flex 4 (spark TitleWindow as opposed to the halo TitleWindow) you can create your own skin and assign that skin in CSS. In your custom skin you can draw the background however you want, including an Ellipse set to the width and height of the TitleWindow.
If you don't want to create a skin, or you are using a halo TitleWindow, you can create a circular mask and set it as the mask property on the TitleWindow. The downside to this approach is that you will probably clip the title and the close button (if it is visible), not to mention the contents as well.
Hope that helps, let me know if you need more details on either of these approaches.
