235 \class QAbstractItemView -

236 -

237 \brief The QAbstractItemView class provides the basic functionality for -

238 item view classes. -

239 -

240 \ingroup model-view -

241 \inmodule QtWidgets -

242 -

243 QAbstractItemView class is the base class for every standard view -

244 that uses a QAbstractItemModel. QAbstractItemView is an abstract -

245 class and cannot itself be instantiated. It provides a standard -

246 interface for interoperating with models through the signals and -

247 slots mechanism, enabling subclasses to be kept up-to-date with -

248 changes to their models. This class provides standard support for -

249 keyboard and mouse navigation, viewport scrolling, item editing, -

250 and selections. The keyboard navigation implements this -

251 functionality: -

252 -

253 \table -

254 \header -

255 \li Keys -

256 \li Functionality -

257 \row -

258 \li Arrow keys -

259 \li Changes the current item and selects it. -

260 \row -

261 \li Ctrl+Arrow keys -

262 \li Changes the current item but does not select it. -

263 \row -

264 \li Shift+Arrow keys -

265 \li Changes the current item and selects it. The previously -

266 selected item(s) is not deselected. -

267 \row -

268 \li Ctr+Space -

269 \li Toggles selection of the current item. -

270 \row -

271 \li Tab/Backtab -

272 \li Changes the current item to the next/previous item. -

273 \row -

274 \li Home/End -

275 \li Selects the first/last item in the model. -

276 \row -

277 \li Page up/Page down -

278 \li Scrolls the rows shown up/down by the number of -

279 visible rows in the view. -

280 \row -

281 \li Ctrl+A -

282 \li Selects all items in the model. -

283 \endtable -

284 -

285 Note that the above table assumes that the -

286 \l{selectionMode}{selection mode} allows the operations. For -

287 instance, you cannot select items if the selection mode is -

288 QAbstractItemView::NoSelection. -

289 -

290 The QAbstractItemView class is one of the \l{Model/View Classes} -

291 and is part of Qt's \l{Model/View Programming}{model/view framework}. -

292 -

293 The view classes that inherit QAbstractItemView only need -

294 to implement their own view-specific functionality, such as -

295 drawing items, returning the geometry of items, finding items, -

296 etc. -

297 -

298 QAbstractItemView provides common slots such as edit() and -

299 setCurrentIndex(). Many protected slots are also provided, including -

300 dataChanged(), rowsInserted(), rowsAboutToBeRemoved(), selectionChanged(), -

301 and currentChanged(). -

302 -

303 The root item is returned by rootIndex(), and the current item by -

304 currentIndex(). To make sure that an item is visible use -

305 scrollTo(). -

306 -

307 Some of QAbstractItemView's functions are concerned with -

308 scrolling, for example setHorizontalScrollMode() and -

309 setVerticalScrollMode(). To set the range of the scroll bars, you -

310 can, for example, reimplement the view's resizeEvent() function: -

311 -

312 \snippet code/src_gui_itemviews_qabstractitemview.cpp 0 -

313 -

314 Note that the range is not updated until the widget is shown. -

315 -

316 Several other functions are concerned with selection control; for -

317 example setSelectionMode(), and setSelectionBehavior(). This class -

318 provides a default selection model to work with -

319 (selectionModel()), but this can be replaced by using -

320 setSelectionModel() with an instance of QItemSelectionModel. -

321 -

322 For complete control over the display and editing of items you can -

323 specify a delegate with setItemDelegate(). -

324 -

325 QAbstractItemView provides a lot of protected functions. Some are -

326 concerned with editing, for example, edit(), and commitData(), -

327 whilst others are keyboard and mouse event handlers. -

328 -

329 \note If you inherit QAbstractItemView and intend to update the contents -

330 of the viewport, you should use viewport->update() instead of -

331 \l{QWidget::update()}{update()} as all painting operations take place on the -

332 viewport. -

338 \enum QAbstractItemView::SelectionMode -

339 -

340 This enum indicates how the view responds to user selections: -

341 -

342 \value SingleSelection When the user selects an item, any already-selected -

343 item becomes unselected, and the user cannot unselect the selected item by -

344 clicking on it. -

345 -

346 \value ContiguousSelection When the user selects an item in the usual way, -

347 the selection is cleared and the new item selected. However, if the user -

348 presses the Shift key while clicking on an item, all items between the -

349 current item and the clicked item are selected or unselected, depending on -

350 the state of the clicked item. -

351 -

352 \value ExtendedSelection When the user selects an item in the usual way, -

353 the selection is cleared and the new item selected. However, if the user -

354 presses the Ctrl key when clicking on an item, the clicked item gets -

355 toggled and all other items are left untouched. If the user presses the -

356 Shift key while clicking on an item, all items between the current item -

357 and the clicked item are selected or unselected, depending on the state of -

358 the clicked item. Multiple items can be selected by dragging the mouse over -

359 them. -

360 -

361 \value MultiSelection When the user selects an item in the usual way, the -

362 selection status of that item is toggled and the other items are left -

363 alone. Multiple items can be toggled by dragging the mouse over them. -

364 -

365 \value NoSelection Items cannot be selected. -

366 -

367 The most commonly used modes are SingleSelection and ExtendedSelection. -
