Flex: Why does setting scaleX/Y in mxml effect the components size but setting it in actionscript does not?
by XLNC in Programming Languages

I'm playing around with the scaleX/Y in the canvas tag and have noticed some strange behaviour. When I set scale in in mxml the width and height of the canvas are adjusted accordingly. For example if I have a canvas like this:

<mx:Canvas width="1000" height="1000" scaleX="0.1" scaleY="0.1" />

The canvas now appears on screen to have a width and height

Is setting image dimensions with CSS as “good” as setting them in HTML?
by jaset in Web Design

When I was first learning HTML a very long time ago, I was told that it was important to always set the dimensions of your images in your HTML, so that browsers could draw an empty box where the image should go, render your page, and then download and render the images where they belong.

Is just setting a value faster than the checking of existance and only setting if doesn't exist - like in this Android / Java code?
by Denis Chaykovskiy in Java


That code is run each time, when the listAdapter requests a new row:

if (textViewTitle != null)


if (textViewTitle != null
&& textViewTitle.getTypeface() != null
&& textViewTitle.getType

PDFBox - Setting or Retaining Font Size while Setting a Field Value
by YoNGaR in Programming Languages

I am using PDTextbox's setValue and setReadOnly to set a form field value. The field is defined using a bar code font. The modified PDF changes the font size to match the height of the field box and this scaling makes the bar code unreadable by a bar code reader. Using the Enfocus PDF Browser I see that the field's normal appearance data stream (field->AP->N->"--data--") shows "/3of9Barcode

Difference between setting `scrollTop` directly and setting it with `$.animate`
by Darren Torpey in Development Tools & Services

In a mousewheel event handler, I changed a statement that updates a element's scrollTop:

- list.scrollTop(newScrollTop);
+ list.animate({
+ scrollTop: newScrollTop
+ }, 80);

I added this animate to make the list scroll smoothly, and it works on Chrome like the original stat

How is the Eclipse JDK setting affecting the system's JDK setting
by jazzyfox in Programming Languages
