Empty rows in ITSMobile screens

More fun deploying ITSMobile screens for mobile devices.  This time, I was tasked with finding a way to shrink the screens so they fit better on the handheld devices used in our factories.  It took a lot of research and trial and error, but I finally satisfied my users.  Here’s a summary, all in one place.

First I concentrated on reducing the horizontal size of the screen elements.  This turned out to be pretty easy: I created a custom generation style using this excellent walkthrough.  I overrode the _COMPUTE_WIDTH_STRING method and changed the emfactor value from 1.0 to 0.8.

The vertical dimension proved more challenging. I knew I could save a lot of space by removing all the empty lines at the bottom of every screen, but it took me a while to figure out how to do this.  Here’s the solution I ended up with: In my custom generator class, I overrode the _CONTENT_EMPTY_SPACE method, which is called for every empty cell.  In the case of a empty row the generator writes a single empty cell that spans the entire screen.  To trap this condition I added the following check:

IF pi_columns = _screen_header-columns. 

Inside this block I grabbed the value of the style attribute ( l_replacement-value) and added ” height:1px; “.  Now all the empty rows are shrunk down to 1 pixel in height, effectively removing them.

One last trick – our mobile devices use Internet Explorer which has a feature where the vertical scrollbar is always visible, even when it’s not needed.  I added the following entry to my mobile.css stylesheet to hide the vertical scrollbar and regain some screen real estate:

html, body {
overflow: auto;
