QCanBusFactory 類是用作 CAN Bus 插件的插件接口的工廠類。 更多...
| 頭： |
#include <QCanBusFactory>
|
| CMake: |
find_package(Qt6 REQUIRED COMPONENTS SerialBus)
target_link_libraries(mytarget PRIVATE Qt6::SerialBus)
|
| qmake: |
QT += serialbus
|
| virtual QList<QCanBusDeviceInfo> | availableDevices (QString * errorMessage ) const = 0 |
| virtual QCanBusDevice * | createDevice (const QString & interfaceName , QString * errorMessage ) const = 0 |
所有插件必須實現此工廠類提供的函數。
[pure virtual]
QList
<
QCanBusDeviceInfo
> QCanBusFactory::
availableDevices
(
QString
*
errorMessage
) const
Returns the list of available devices and their capabilities for the QCanBusDevice .
errorMessage contains an error description in case of failure.
[pure virtual]
QCanBusDevice
*QCanBusFactory::
createDevice
(const
QString
&
interfaceName
,
QString
*
errorMessage
) const
創建新的 QCanBusDevice . The caller must take ownership of the returned pointer.
interfaceName is the CAN interface name and errorMessage contains an error description in case of failure.
