223 | /*
224 | * Adapts the sidebar widget states to the available vertical space.
225 | *
226 | * The sidebar contains two widgets stacked vertically with spacing between
227 | * them: the InfoBannerWidget (tips/sponsors) and the LearnCardWidget (docs
228 | * links + action buttons). Both support a compact mode to reduce their
229 | * height when the window is small.
230 | *
231 | * Collapse order (as the window shrinks):
232 | * 1. LearnCardWidget links collapse (vertical list -> horizontal row)
233 | * 2. InfoBannerWidget compacts (hides illustration and body text)
234 | *
235 | * Expand order (as the window grows) is the reverse:
236 | * 1. InfoBannerWidget expands back to full
237 | * 2. LearnCardWidget links expand back to vertical
238 | *
239 | * All size values are queried from the widgets and layout, not hardcoded:
240 | * - tipsFull: InfoBannerWidget::sizeHint().height()
241 | * Always returns the full preferred height (360) regardless
242 | * of compact state. This is stable because sizeHint()
243 | * reports what the widget *wants*, while compact mode is
244 | * enforced via setMaximumHeight().
245 | * - learnMax: LearnCardWidget::maximumHeight() (from .ui: 240)
246 | * - learnMin: LearnCardWidget::minimumHeight() (from .ui: 110)
247 | * - spacing: sidebarLayout->spacing() (from .ui: 16)
248 | *
249 | * Hysteresis (kHysteresis = 20px):
250 | * Without hysteresis, at the exact collapse threshold the layout
251 | * oscillates: collapsing a widget frees space, which satisfies the
252 | * expand threshold, which expands, which exceeds the threshold again.
253 | * On each resize event this cycle repeats, causing visible flickering.
254 | *
255 | * Hysteresis adds a dead zone between collapse and expand thresholds.
256 | * A widget collapses at threshold T but only re-expands at T + 20.
257 | * In the 20px gap, the current state is preserved.
258 | *
259 | * The value 20px was chosen empirically: it must be large enough that
260 | * the layout geometry change from collapsing/expanding a widget (which
261 | * can shift available height by a few pixels due to rounding, spacing,
262 | * and platform differences) doesn't cross back over the threshold. In
263 | * practice, resize events during a user drag arrive ~8-12px apart, so
264 | * 20px ensures at least one stable frame at the boundary. A larger
265 | * value would delay the transition visibly; a smaller one risks not
266 | * fully suppressing the oscillation on high-DPI displays where pixel
267 | * increments are coarser.
268 | *
269 | * Decision zones (with current widget sizes):
270 | *
271 | * available >= 636 (linksExpandAt)
272 | * -> full tips + expanded links
273 | *
274 | * available >= 506 (tipsExpandAt) and < 636
275 | * -> full tips + collapsed links
276 | * (between 616-635: hysteresis zone for links -- keeps current state
277 | * if already expanded, won't re-expand if collapsed)
278 | *
279 | * available >= 486 (tipsCompactAt) and < 506
280 | * -> hysteresis zone for tips -- keeps current tips state,
281 | * links forced collapsed
282 | *
283 | * available < 486 (tipsCompactAt)
284 | * -> compact tips + collapsed links
285 | *
286 | * Called from: resizeEvent(), showEvent(), appInitialized(), and
287 | * indirectly via updateGeometry() when the welcome header banner
288 | * visibility changes.
