I have a question to you. I'm working with Pega 7.1.7 and have the following setting:
The application has to run in a window of a fixed size.
The Harness I use has 3 containers
a header part,
a middle part,
and a footer.
The content of header and footer are known and don't cause any trouble.
However, the middle part can vary quite a lot. In particular, there are situations in which the fixed size of the window does not suffice and a scrollbar appears. The requirements about the colors then show an unaesthetic behaviour of Pega. As soon as the scrollbar appears, pega recalculates the size of the content window (the scrollbar is seemingly not considered to be part of the window). In particular, you can see that the containers are being "resized" as soon as the scrollbar appears, which is distracting (actually, you see a grey shape (container) "hopping") .
Therefore my question: Is it possible to tell Pega to ignore the scrollbar width? The padding I defined is more than sufficient to comfortably accomodate the scrollbar, and hence I don't require Pega's auto-resize.
Its difficult to visualize the issue based on the description, however have you tried using Screen layouts (for your scenario Header Footer could work) ? Does the issue with scrollbar happen with screen layouts as well ?
Yes the content of the "middle" layer changes dynamically. There is one button for a longer version of text. If this is pressed it is possible (but not necessary) that the content becomes too large for the given space and the scrollbar appears. Then you see the described flicker.
If the content is too large at Initial load, then the scrollbar is already present. You then don't see any flicker, but this still impacts the layout (the content in the "footer" layer is alligned to the middle layer (when there is no scrollbar). As soon as the scrollbar appears, the allignment is not correct any longer.)
