API:HorizontalScrollbarSetPageSize

UI Lua API · Scrollbar functions
Version: WAR 1.4.8

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

HorizontalScrollbarSetPageSize(scrollbarName, size)

Arguments

scrollbarName

string – Name of the HorizontalScrollbar.

size

number – The value to store.

Returns

Nothing.

Details

• The client passes the arguments to the scrollbar in the wrong order: size becomes the line size (returned by HorizontalScrollbarGetLineSize). The page size and the maximum scroll position are not changed.
• To set the page size, use HorizontalScrollbarSetLineSize, which has the opposite mix-up. To set both values, call:

HorizontalScrollbarSetLineSize( name, pageSize )   -- sets the page size (line size becomes the old page size)
HorizontalScrollbarSetPageSize( name, lineSize )   -- sets the line size

• 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 'HorizontalScrollbarSetPageSize': Window %s does not exist
