Scaling widget size

Hi, I wanted to ask if its possible to scale widgets? I’ve tried to resize a slider-element in various ways (height-keyword, putting it in a VBox, putting it in a row and use the sizing kw …) but there a no changes visible. seems to have been closed, due to it getting changed in 0.12X . I haven’t found any examples of this in the gallery either.

My goal is to increase the length of Slider since it is, depending on how many values youre allowed to slide over, pretty much a pain to use. Also the slider covers its own “value-counter” in vertical orientation when selecting its max value.

best regards
