API:VerticalScrollbarSetLineSize

UI Lua API · Scrollbar functions
Version: WAR 1.4.8

Meant to set the line size of a VerticalScrollbar. In the current client it sets the page size instead. See Details.

VerticalScrollbarSetLineSize(scrollbarName, size)

Arguments

scrollbarName

string – Name of the VerticalScrollbar.

size

number – The value to store.

Returns

Nothing.

Details

• The client passes the arguments to the scrollbar in the wrong order:
  • size becomes the page size (returned by VerticalScrollbarGetPageSize).
  • The line size is set to the page size the scrollbar had before the call.
  • If size is larger than the maximum scroll position, the maximum is raised to size.
• To set the line size, use VerticalScrollbarSetPageSize, which has the opposite mix-up. See that page for a call order that sets both values.
• The thumb is recalculated and the current position is clamped again. If that moves the position, the OnScrollPosChanged handler runs.
• The stock UI never calls this function.
• The function needs at least two arguments and only reads the last two. Any extra arguments placed in front of them are ignored.

Errors

• Error in function call 'VerticalScrollbarSetLineSize': Window %s does not exist
