You can also use this program to - verify that Qt is actually receiving mouse events from your mouse. - - Many 'gamer' mouse devices are configured with high-numbered "buttons" - sending text shortcuts for certain games. With such a mouse, no mouse - button events occur: The "mouse" sends keystrokes, and the - 'Mouse Button Tester' Window will not see the event. Receiving no event, - it will not repaint the Window with new text describing a button event. - - And so, in addition to it's use as Qt example code, the program may be - useful s a mouse device tester. Note that there is another example - mouse buttons example which provides the same function, written in QML. - - This program (the Widget-based example) consists of three classes, - in addition to the main() parent program: - - \list - \li \c A QPushButton, "Quit". - \li \c ButtonTester. This is derived from Qt's TextArea class, for - purpose of customizing/re-implementing the mouse and wheel event - member functions. - \li \c A simple QVBoxLayout layout. - \endlist - - First we will review the main program, with it's layout and "Quit" - QPushButton. Then we will take a look at the \c ButtonTester class. - - \section1 The Main Program - - Note that the QPushButton, "Quit", is defined directly within the main() - program, rather than another class. This is a correct way of defining a - "Quit" QPushButton: A "Quit" Button defined inside another - class would result in the destructor of that second class being - called twice. This "Quit" Button uses the traditional Signal/Slot - connection to invoke termination of the QApp, which will properly destroy - its child classes before terminating itself. - - The remainder of the main() program is concerned with defining the layout, - and applying a minimum size to the customized ButtonTester. - - \section1 ButtonTester Class Definition - - The \c ButtonTester class inherits from QTextEdit, and listens for - mouse events on all possible Qt::MouseButton values. It also listens for - wheel events from the mouse, and indicates the direction of wheel motion - ("up", down", "left", or "right"). It prints short debug messages into - the Window, and also on the console QDebug() stream, when mouse button - and wheel events occur. Our reimplementation of mousePressEvent(), - mouseReleaseEvent(), mouseDoubleClickEvent(), and wheelEvent() "drive" - the program; the other functions simply convert the Qt::MouseButton - values into text strings. - - You should call the ignore() function on any mouse event (or other event) - which your widget-based classes do not use and consume. This function - assures that Qt will propagate the event through each parent widget, - until it is used or propagated to the Window Manager. (Qt attempts to do - this automatically, but it is better programming practice to explicitly - invoke the function.) - - \image mousebutton-buttontester.png -*/ diff --git a/examples/widgets/widgets/CMakeLists.txt b/examples/widgets/widgets/CMakeLists.txt index 35118b984d..06f57d1e28 100644 --- a/examples/widgets/widgets/CMakeLists.txt +++ b/examples/widgets/widgets/CMakeLists.txt @@ -15,7 +15,6 @@ qt_internal_add_example(lineedits) if(QT_FEATURE_movie) qt_internal_add_example(movie) endif() -qt_internal_add_example(mousebuttons) qt_internal_add_example(scribble) qt_internal_add_example(shapedclock) qt_internal_add_example(shortcuteditor) diff --git a/examples/widgets/widgets/mousebuttons/CMakeLists.txt b/examples/widgets/widgets/mousebuttons/CMakeLists.txt deleted file mode 100644 index 2957a2b787..0000000000 --- a/examples/widgets/widgets/mousebuttons/CMakeLists.txt +++ /dev/null @@ -1,37 +0,0 @@ -# Copyright (C) 2022 The Qt Company Ltd. -# SPDX-License-Identifier: BSD-3-Clause - -cmake_minimum_required(VERSION 3.16) -project(mousebuttons LANGUAGES CXX) - -if(NOT DEFINED INSTALL_EXAMPLESDIR) - set(INSTALL_EXAMPLESDIR "examples") -endif() - -set(INSTALL_EXAMPLEDIR "${INSTALL_EXAMPLESDIR}/widgets/widgets/mousebuttons") - -find_package(Qt6 REQUIRED COMPONENTS Core Gui Widgets) - -qt_standard_project_setup() - -qt_add_executable(mousebuttons - buttontester.cpp buttontester.h - main.cpp -) - -set_target_properties(mousebuttons PROPERTIES - WIN32_EXECUTABLE TRUE - MACOSX_BUNDLE TRUE -) - -target_link_libraries(mousebuttons PRIVATE - Qt6::Core - Qt6::Gui - Qt6::Widgets -) - -install(TARGETS mousebuttons - RUNTIME DESTINATION "${INSTALL_EXAMPLEDIR}" - BUNDLE DESTINATION "${INSTALL_EXAMPLEDIR}" - LIBRARY DESTINATION "${INSTALL_EXAMPLEDIR}" -) diff --git a/examples/widgets/widgets/mousebuttons/buttontester.cpp b/examples/widgets/widgets/mousebuttons/buttontester.cpp deleted file mode 100644 index f2cbd4ea06..0000000000 --- a/examples/widgets/widgets/mousebuttons/buttontester.cpp +++ /dev/null @@ -1,184 +0,0 @@ -// Copyright (C) 2016 The Qt Company Ltd. -// Copyright (C) 2016 Rick Stockton <rickstockton@reno-computerhelp.com> -// SPDX-License-Identifier: LicenseRef-Qt-Commercial OR BSD-3-Clause - -#include "buttontester.h" - -#include <QDebug> - -void ButtonTester::mousePressEvent(QMouseEvent *e) -{ - int j = ButtonTester::buttonByNumber (e->button()); - QString result = "Mouse Press: raw button=" + QString::number(j) - + " Qt=" + enumNameFromValue(e->button()); - QString buttonsString = ButtonTester::enumNamesFromMouseButtons(e->buttons()); - result += "\n heldbuttons " + buttonsString; - qDebug() << result; - this->setText(result); - this->repaint(); -} - -void ButtonTester::mouseReleaseEvent(QMouseEvent *e) -{ - int j = ButtonTester::buttonByNumber (e->button()); - QString result = "Mouse Release: raw button=" + QString::number(j) - + " Qt=" + enumNameFromValue(e->button()); - QString buttonsString = ButtonTester::enumNamesFromMouseButtons(e->buttons()); - result += "\n heldbuttons " + buttonsString; - qDebug() << result; - this->setText(result); - this->repaint(); - -} - -void ButtonTester::mouseDoubleClickEvent(QMouseEvent *e) -{ - int j = ButtonTester::buttonByNumber (e->button()); - QString result = "Mouse DoubleClick: raw button=" + QString::number(j) - + " Qt=" + enumNameFromValue(e->button()); - QString buttonsString = ButtonTester::enumNamesFromMouseButtons(e->buttons()); - result += "\n heldbuttons" + buttonsString; - qDebug() << result; - this->setText(result); -} - -#if QT_CONFIG(wheelevent) -void ButtonTester::wheelEvent (QWheelEvent *e) -{ - QString result; - const bool vertical = qAbs(e->angleDelta().y()) >= qAbs(e->angleDelta().x()); - const int delta = vertical ? e->angleDelta().y() : e->angleDelta().x(); - if (delta > 0) { - if (vertical) { - result = "Mouse Wheel Event: UP"; - } else { - result = "Mouse Wheel Event: LEFT"; - } - } else if (delta < 0) { - if (vertical) { - result = "Mouse Wheel Event: DOWN"; - } else { - result = "Mouse Wheel Event: RIGHT"; - } - } - qDebug() << result; - this->setText(result); -} -#endif - -int ButtonTester::buttonByNumber(const Qt::MouseButton button) -{ - if (button == Qt::NoButton) return 0; - if (button == Qt::LeftButton) return 1; - if (button == Qt::RightButton) return 2; - if (button == Qt::MiddleButton) return 3; - -/* Please note that Qt Button #4 corresponds to button #8 on all - * platforms which EMULATE wheel events by creating button events - * (Button #4 = Scroll Up; Button #5 = Scroll Down; Button #6 = Scroll - * Left; and Button #7 = Scroll Right.)
