Tiles

Wrapping grid of fixed-size tiles. Each tile is drawn by a user-supplied ItemRender callback. The number of columns is computed at render time from the content width: cols = max(1, contentWidth / tileWidth).

Constructor: NewTiles(id, class string, render ItemRender, tileWidth, tileHeight int) *Tiles

tileWidth and tileHeight must be ≥ 1 (panics otherwise).

type ItemRender func(r *Renderer, x, y, w, h, index int, data any, selected, focused bool)

Methods

• Items() []any — current items
• SetItems(items []any) — replace all items
• SetDisabled(indices []int) — mark item indices as non-selectable (skipped by navigation)
• Selected() int — current highlighted index (-1 if empty)
• Select(index int) — set highlighted index; fires EvtSelect
• Move(dr, dc int) — move selection by row/column delta
• First() / Last() — jump to first/last enabled item
• PageUp() / PageDown() — scroll by viewport height

Events

Event	Data	Description
"select"	int	Highlighted item index changed
"activate"	int	Item activated via Enter or double-click

Notes

Flags: "focusable".

Navigation wraps between rows in reading order: moving right past the last column advances to the first column of the next row; moving up/down keeps the current column. A vertical scrollbar is drawn when the items don't fit; toggle via the internal scrollbar field (set during construction; no public setter).

SetItems accepts any slice — []string, []MyStruct, etc. — passed through []any. The render callback gets the raw data any and is responsible for type-asserting.
