Detailed Description

Syncs a slider measured in percentage with a spin box measuring real value getting value from parentValueOp.

E.g.

parentValueOp() — total system memory in MiB slider — percentage of the memory we can use spinBox — amount o fmemory we can use in MiB slotParentValueChanged() — should be called every time total memory changes
