Do you want to know how you can integrate the ExtJS Javascript Library into Oracle Application Express (APEX)?
Mark Lancaster has set up an ExtJS example application showing the integration and how such an Oracle APEX application could look like. Check it out!
Oracle Application Express (APEX) doesn’t come with a built-in Slider Control widget, but it’s quite easy to integrate one of the existing Javascript libraries like the Tigra Slider Control. See there example page 1 and page 2 for how the sliders can look like. But you can also use your own images for the slider.
Do you want to improve the usability of the Oracle APEX Shuttle Widget a little bit?
Let’s enhance it by adding support for double click. It will allow users to double click on an entry in one of the two lists of the shuttle, to move the selected entry to the other list as they would normally do with the corresponding icons. I think that’s a little bit more convenient and faster than using the icons.
There comes the necessary code.

Some time ago I was asked if it’s possible to set the background color of the entries of a select list.
Sure why not! I thought I had already answered the question before, so I searched on the OTN forum but didn’t find my posting. No problem, shouldn’t be too hard to find the solution again.
Just noticed a slightly different behavior of $x in Oracle APEX 3.0.
Probably many of you just use it to pass the id-string of an element (eg. $x(“P4_TEST”)) to this function to get the object of this field/div/… id, but you can also call it with an object and in that case the function will just return the object which has been passed in.
You may ask when do you need that? Continue reading

Today there was a thread on the OTN forum about how to access a Tabular Form cell with JavaScript and I thought it might be of general interest.
You have a Tabular Form with 3 columns (Amount, Tax, Total) and want to populate the Total column with the sum of Amount and Tax as soon as Tax has been entered.
If you are a JavaScript developer or create your web-pages with CSS, then the Firefox add-on Firebug is a must have for you!
There is a new beta available, with lot of features, compared to the one hosted by the Firefox extension web-site.
Never heard of Firebug? Continue reading
Just kidding 
I was just looking for an eye catcher…
Maybe you have already seen my announcement that I have released v0.17 of the ApexLib Framework, which contains a lot new features.
The previous features in the Framework mostly concentrated on improvements of Oracle APEX on the server, so that’s easier to access Tabular Forms or do automatic validation of date picker or numeric items. The main idea was to make APEX applications more secure without having to do a lot of additional coding. Continue reading
If you are using Firefox for your APEX development you may want to check out my list of add-ons I’m currently using for the web development. If you have any useful add-ons you are using, drop me a note!
