* Cleanup QtWidgets (widgets) examplesChristian Ehrlicher2019-09-171-14/+11
| | | | | | | | | | | | | Cleanup QtWidgets widgets examples: - use member-init (clang-tidy) - fix includes/don't include QtWidgets globally - include own header first - use nullptr (clang-tidy) - avoid c-style casts - use QVector instead QList Change-Id: Ib56bb507eb2ef885f1ddc664050d3c7af92adb70 Reviewed-by: Friedemann Kleint <Friedemann.Kleint@qt.io>
* Tablet example: add a menu item to clear the canvasShawn Rutledge2018-08-231-0/+1
| | | | | | | | It's annoying to have to kill the app and start over when it gets too cluttered. Change-Id: Ic72e372e5742de4e7c6bb818a3150283498a517b Reviewed-by: Friedemann Kleint <Friedemann.Kleint@qt.io>
* Tablet example: update only the drawn areas of the canvasShawn Rutledge2017-09-151-1/+1
| | | | | | | | This makes an enormous difference in responsiveness on the iPad Pro: it actually feels like real-time drawing with hardly any lag. Change-Id: I17c3b948e818d4ee46b4d24934c929ab9b386e69 Reviewed-by: Richard Moe Gustavsen <richard.gustavsen@qt.io>
* tablet example: make smoother strokes with the rotation stylusShawn Rutledge2017-05-081-0/+2
| | | | | | | | | | Each stroke is a polygon (quadrilateral) connecting the previous tablet event point to the current one. Previously we used the same width for both ends of the stroke, so rapid changes in pressure caused steps in the stroke width. Now it is tapered from one end to the other.

* Polish the Tablet exampleShawn Rutledge2016-01-281-25/+21
| | | | | | | | | | | | | | | | | | | | | - Introduce Qt 5 signal-slot connection syntax. - Merge MainWindow::createMenus()/createActions() into MainWindow::createMenus(), removing the need to store the actions as member variables. Use QMenu::addAction() for brevity. - For actions in QActionGroups, carry the Valuator enum in QAction::data so that the slot to handle the selection does not need to compare the QAction pointer itself. - Use a non-modal QColorDialog, so that the user can change colors more easily while drawing. - Choose saner shortcut keys: control-Q should not override the default usage for quitting the application, and using shortcuts for About dialogs is anyway dubious. - Improve the example documentation.

* Tablet example: smoother, rotation stylus, better airbrushShawn Rutledge2015-07-311-2/+6
| | | | | | | | | | | | The drawing is antialiased and with rounded caps and joins. Rotation stylus acts like a felt marker. Airbrush sprays a radial gradient of color, and its alpha can depend on the tangential pressure if so chosen.

* Update copyright headersJani Heikkinen2015-02-111-5/+5
| | | | | | | | | | | | | | | | | | Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to qt.io. Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination. New header.LGPL-COMM taken in the use file which were using old header.LGPL3 (src/plugins/platforms/android/extract.cpp) Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license combination Change-Id: I6f49b819a8a20cc4f88b794a8f6726d975e8ffbe Reviewed-by: Matti Paaso <matti.paaso@theqtcompany.com>
* Examples: Add Q_DECL_OVERRIDE to overridden functionsOlivier Goffart2014-07-151-3/+3
| | | | | | | | | | | | | | | | | | Q_DECL_OVERRIDE (which expands to 'override' for supported compiler) helps to declare the intent (that it is an overridden function) and force compilation error when there is no such virtual function in the base class. The examples should show the best practice of having it, as it may save the programmer quite some time in case of change of API or typo in the function name or arguments. This change was done automatically with clang-modernize -add-override -override-macros And fixed MSVC compilation by removing inline for TorrentViewDelegate::paint Change-Id: Ice66ae93fae571266f908703d5b8892b2c1ebb1a Reviewed-by: Jędrzej Nowacki <jedrzej.nowacki@digia.com>
