Have a small question... In my HTML5 (web) publication I've a text box which is filled with information by collecting data from a database. In the text box a variable (which holds the data from the database) is inserted to put the text there, which works OK.
However, some of the text is much larger than the text box can show, but I can't find the solution to scroll the text as scroll bars don't seem to work.
Please note that when I add some static text, it all seems to work OK...

Hi Jan,

If you're using Firebug, right click on the text box and inspect the element. You'll notice that it's a DIV that contains an SVG element and another DIV with your content. Scrollbars in HTML are controlled by the CSS overflow property and these are set to hidden but need to be changed to auto.

There are various ways you could achieve this including adding the following code to an on-show on the text box:

Code:
document.getElementById(this.m_elementId).getElementsByTagName("DIV")[0].style.overflow = "auto";


Because this uses the default HTML scrollbars, you don't need to add them in Opus.

Mack

Well, as I'm not a programmer by profession and do this as a hobby, I sometimes need the skills of the professionals :wink:
It works Mack... MANY THANKS!
