My name is Pedro DV. I’m a Software Engineer, Entrepreneur with studies and experience in User Experience and User Interface Design. I love and have an extensive experience creating user interfaces.
I'm a freelancer / consultant and the owner of Pixel Duke a software consultancy company specialized in front end / user interface development in various technologies. Many years of expertise in Java and its UI platform JavaFX and formely Swing but have worked and can also work with other technologies. More information here and for a detailed CV style report my LinkedIn page.
It’s been too long since my last post! I plan on posting more regularly in the coming future.
Meanwhile, I took the opportunity to re-design this site which was looking pretty bad. Also thought my free open source libraries needed more attention, namely documentation so I’ve started working on that. The first one is going to be JMetro, you can check out the documentation here.
While I was looking over JMetro to write the documentation, I noticed some bugs and also a few aesthetic issues that I fixed:
Spinner: remove white background glitch with some style classes
List Box: added border around control
Slider: Somehow the fix to the slider when in vertical orientation, that fixed the fact that the fill started from the top instead of the bottom got lost. I re-implemented this fix.
Still haven’t had time with the font rendering issue. You can notice poor font rendering in JMetro on Windows with text in big font sizes. This is probably a JavaFX bug/problem because I’ve seen this elsewhere on images in other people’s blog posts and also other applications I’ve worked on.
I decided to give it a go at testing javafx in an android device. My android device might be considered a low end device, it’s a nexus 4 from LG. The result can be seen below in a video. The quality of the video isn’t the best, I had to scale down the quality because the video was occupying 2GB.
My conclusion is that java/javafx runs with a very good performance in a low end android device with a pretty decent start up time. There were just 2 problems with this test, the first was with a demo which tested multi touch but didn’t run with top notch responsiveness but that might be the demos fault and not an issue with javafx itself. The second problem were dialogs: they aren’t showing up well.
The demo took about 6 seconds to start which is more than the standard android app but not too much.
Going through JMetro I just remembered the Toggle Switch control that I have created. It reminded me that this should be in a control repository next to other controls, publicly available for anyone to grab. I think this is one of those controls that should be part of the java sdk, it’s very popular especially on touch based devices. For more information read my previous blog post on the Toggle Switch control.
I have heard more than once people saying why a new control, why not simply style the Checkbox to appear the same way as a Toggle Switch. I think Toggle Switch merits being its own control the same way the Radio Button and Checkbox aren’t just skins of the Toggle Button, besides being conceptually a different control a Checkbox has the indeterminate state which doesn’t make sense in a Toggle Switch. Toggle Switch are usually also animated which can’t be achieved by skinning. And finally creating a Toggle Switch control makes it easier for others to style the control in different ways via css (styling a Checkbox to look like a Toggle Switch is difficult and hacky) .
One of the pertinent feedbacks I’ve received from the project members was that the default skin should be inline with the Modena theme. And so I created a new css stylesheet that I think is inline with Modena and is the default look of the control (if you don’t override the default stylesheet).
