Masking Techniques

We can mask over a number of different objects by putting a 1 row portal with no border, based on the FOC = FOCUS table occurrence for the data being modified. In the images that follow, the invisible portal row is on the right hand side.

In the case of the layout that displays a list of projects, if no project is selected, then no matching ID is present in GT_ID_FOCUS, and as such no ‘focus’.

Once the user has highlighted a row in the portal, the focus is evident (to the right). See the illustration below:

Another masking technique employed is that of putting a text object with a single space in it, and attaching a conditional formatting calculation to the object.
