Hi,
I’m implementing a custom scrollbar-like widget, and try to make it accessible.
According to the ARIA specs here and here, the valuenow should be between valuemin and valuemax, and typically presented as percentage.
Looking at gtk implementation, the adjustment’s upper property is used for valuemax, but in that case valuenow can never reach it because the adjustment page_size is not taken in account.
Is gtk correct in that regard? shouldn’t it set valuemax to upper - page_size?
