\class QOperatingSystemVersion
|
||||||
|
\inmodule QtCore
|
||||||
|
\since 5.9
|
||||||
|
\brief The QOperatingSystemVersion class provides information about the
|
||||||
|
operating system version.
|
||||||
|
|
||||||
|
Unlike other version functions in QSysInfo, QOperatingSystemVersion provides
|
||||||
|
access to the full version number that \a developers typically use to vary
|
||||||
|
behavior or determine whether to enable APIs or features based on the
|
||||||
|
operating system version (as opposed to the kernel version number or
|
||||||
|
marketing version).
|
||||||
|
|
||||||
|
This class is also a complete replacement for QSysInfo::macVersion and
|
||||||
|
QSysInfo::windowsVersion, additionally providing access to the third (micro)
|
||||||
|
version number component.
|
||||||
|
|
||||||
|
Presently, Android, Apple Platforms (iOS, macOS, tvOS, and watchOS),
|
||||||
|
and Windows are supported.
|
||||||
|
|
||||||
|
The \a majorVersion(), \a minorVersion(), and \a microVersion() functions
|
||||||
|
return the parts of the operating system version number based on:
|
||||||
|
|
||||||
|
\table
|
||||||
|
\header
|
||||||
|
\li Platforms
|
||||||
|
\li Value
|
||||||
|
\row
|
||||||
|
\li Android
|
||||||
|
\li result of parsing
|
||||||
|
\l{https://developer.android.com/reference/android/os/Build.VERSION.html#RELEASE}{android.os.Build.VERSION.RELEASE}
|
||||||
|
using QVersionNumber, with a fallback to
|
||||||
|
\l{https://developer.android.com/reference/android/os/Build.VERSION.html#SDK_INT}{android.os.Build.VERSION.SDK_INT}
|
||||||
|
to determine the major and minor version component if the former
|
||||||
|
fails
|
||||||
|
\row
|
||||||
|
\li Apple Platforms
|
||||||
|
\li majorVersion, minorVersion, and patchVersion from
|
||||||
|
\l{https://developer.apple.com/reference/foundation/nsprocessinfo/1410906-operatingsystemversion?language=objc}{NSProcessInfo.operatingSystemVersion}
|
||||||
|
\row
|
||||||
|
\li Windows
|
||||||
|
\li dwMajorVersion, dwMinorVersion, and dwBuildNumber from
|
||||||
|
\l{https://msdn.microsoft.com/en-us/library/mt723418.aspx}{RtlGetVersion} -
|
||||||
|
note that this function ALWAYS return the version number of the
|
||||||
|
underlying operating system, as opposed to the shim underneath
|
||||||
|
GetVersionEx that hides the real version number if the
|
||||||
|
application is not manifested for that version of the OS
|
||||||
|
\endtable
|
||||||
|
|
||||||
|
Because QOperatingSystemVersion stores both a version number and an OS type, the OS type
|
||||||
|
can be taken into account when performing comparisons. For example, on a macOS system running
|
||||||
|
macOS Sierra (v10.12), the following expression will return \c false even though the
|
||||||
|
major version number component of the object on the left hand side of the expression (10) is
|
||||||
|
greater than that of the object on the right (9):
|
||||||
|
|
||||||
|
\snippet code/src_corelib_global_qoperatingsystemversion.cpp 0
|
||||||
|
|
||||||
|
This allows expressions for multiple operating systems to be joined with a logical OR operator
|
||||||
|
and still work as expected. For example:
|
||||||
|
|
||||||
|
\snippet code/src_corelib_global_qoperatingsystemversion.cpp 1
|
||||||
|
|
||||||
|
A more naive comparison algorithm might incorrectly return true on all versions of macOS,
|
||||||
|
including Mac OS 9. This behavior is achieved by overloading the comparison operators to return
|
||||||
|
\c false whenever the OS types of the QOperatingSystemVersion instances being compared do not
|
||||||
|
match. Be aware that due to this it can be the case \c x >= y and \c x < y are BOTH \c false
|
||||||
|
for the same instances of \c x and \c y.

||||||

to macOS 11.0. If not it will correspond to macOS 10.16.

\class QSlider
|
||||||
|
\brief The QSlider widget provides a vertical or horizontal slider.
|
||||||
|
|
||||||
|
\ingroup basicwidgets
|
||||||
|
\inmodule QtWidgets
|
||||||

|
||||||
|
|
||||||
|
The slider is the classic widget for controlling a bounded value.
|
||||||
|
It lets the user move a slider handle along a horizontal or vertical
|
||||||
|
groove and translates the handle's position into an integer value
|
||||||
|
within the legal range.
|
||||||
|
|
||||||
|
QSlider has very few of its own functions; most of the functionality is in
|
||||||
|
QAbstractSlider. The most useful functions are setValue() to set
|
||||||
|
the slider directly to some value; triggerAction() to simulate
|
||||||
|
the effects of clicking (useful for shortcut keys);
|
||||||
|
setSingleStep(), setPageStep() to set the steps; and setMinimum()
|
||||||
|
and setMaximum() to define the range of the scroll bar.
|
||||||
|
|
||||||
|
QSlider provides methods for controlling tickmarks. You can use
|
||||||
|
setTickPosition() to indicate where you want the tickmarks to be,
|
||||||
|
setTickInterval() to indicate how many of them you want. the
|
||||||
|
currently set tick position and interval can be queried using the
|
||||||
|
tickPosition() and tickInterval() functions, respectively.
|
||||||
|
|
||||||
|
QSlider inherits a comprehensive set of signals:
|
||||||
|
\table
|
||||||
|
\header \li Signal \li Description
|
||||||
|
\row \li \l valueChanged()
|
||||||
|
\li Emitted when the slider's value has changed. The tracking()
|
||||||
|
determines whether this signal is emitted during user
|
||||||
|
interaction.
|
||||||
|
\row \li \l sliderPressed()
|
||||||
|
\li Emitted when the user starts to drag the slider.
|
||||||
|
\row \li \l sliderMoved()
|
||||||
|
\li Emitted when the user drags the slider.
|
||||||
|
\row \li \l sliderReleased()
|
||||||
|
\li Emitted when the user releases the slider.
|
||||||
|
\endtable
|
||||||
|
|
||||||
|
QSlider only provides integer ranges. Note that although
|
||||||
|
QSlider handles very large numbers, it becomes difficult for users
|
||||||
|
to use a slider accurately for very large ranges.
|
||||||
|
|
||||||
|
A slider accepts focus on Tab and provides both a mouse wheel and a
|
||||||
|
keyboard interface. The keyboard interface is the following:
|
||||||
|
|
||||||
|
\list
|
||||||
|
\li Left/Right move a horizontal slider by one single step.
|
||||||
|
\li Up/Down move a vertical slider by one single step.
|
||||||
|
\li PageUp moves up one page.
|
||||||
|
\li PageDown moves down one page.
|
||||||
|
\li Home moves to the start (mininum).
|
||||||
|
\li End moves to the end (maximum).
|
||||||
|
\endlist
