Description John Gymer

The Slider widget does not calculate positions correctly when setThumb() is > 1.

For example:
								slider.setMinimum(0);
slider.setMaximum(101); // for some reason, Sliders go up to Max-1 in SWT
slider.setIncrement(1);
slider.setPageIncrement(10);
slider.setThumb(10);

This should give a possible range of 0-100, as it does in SWT.
However, in RAP, the maximum possible is only 91, due to the Thumb size.

Thanks, John

John, just checked it in SWT (Windows) and it behaves exactly like in RAP - with the setup above the maximum possible value is 91 (max - thumb size). Please reopen if you disagree.

Sorry Ivan,
You are absolutely correct.
It seems a silly way to do it, but yes, SWT works the same way.
I have adjusted by code (SWT, RAP and TABRIS) to set the slider's Max to my maximum value PLUS the thumb size.
Thanks, John
