Hi Antonio,
Thanks for looking into this. The problem I see with
scrollbars right now is that they are shown if the Matrix is large enough
to fill the space it is put in. The matrix control requires that the matrix
size be smaller than the maximum size by the scroll bar size. So when the
scroll bar is not shown then we see a blank area where the scroll bars
could would be shown when the matrix increases in size.
I wanted to keep the scroll bars hidden even when the matrix
occupies the entire area of the control and only show the scroll bars when
the matrix wants to grow beyond that. Now when the scroll bars have to be
shown then to make things visible the visible area of the matrix would have
to be reduced a little bit to allow the scroll bars to be displayed.
I was trying to do it manually by sizing the matrix to the
size available and then forcing the scroll bars to auto hide by setting dx
and dy but that does not work properly because I think IUP recalculates
them and the scroll bar shows up back.
Thanks,
Milind
