Changelog ========= __v3.0a__ -------- * Depricated secondary instances count. * Added a sendMessage() method to send a message to the primary instance. * Added a receivedMessage() signal, emmited when a message is received from a secondary instance. * The SingleApplication constructor's third parameter is now a bool specifying if the current instance should be allowed to run as a secondary instance of there is already a primary instance. * The SingleApplication constructor accept a fourth parameter specifying if the SingleApplication block should be User-wide or System-wide. * SingleApplication no longer relies on `applicationName` and `organizationName` to be set. It instead concatenates all of the following data and computes a `SHA256` hash which is uses as the key for the `QSharedMemory` block and the `QLocalServer`. Since at least `applicationFilePath` is always present there is no need to explicitly set any of these prior to initialising `SingleApplication`. * QCoreApplication::applicationName * QCoreApplication::applicationVersion * QCoreApplication::applicationFilePath * QCoreApplication::organizationName * QCoreApplication::organizationDomain * User name or home directory path if in User mode * The primary instance is no longer notified when a secondary instance had been started by default. An setting for this feature exists. * Added instanceNumber() which represents a unique identifier for each secondary instance started. When called from the primary instance will return `0`. __v2.4__ -------- * Stability improvements * Support for secondary instances. * The library now recovers safely after the primary process has crashed and the shared memory had not been deleted. __v2.3__ -------- * Improved pimpl design and inheritance safety. _Vladislav Pyatnichenko_ __v2.2__ -------- * The `QAPPLICATION_CLASS` macro can now be defined in the file including the Single Application header or with a `DEFINES+=` statement in the project file. __v2.1__ -------- * A race condition can no longer occur when starting two processes nearly simultaneously. Fix issue [#3](https://github.com/itay-grudev/SingleApplication/issues/3) __v2.0__ -------- * SingleApplication is now being passed a reference to `argc` instead of a copy. Fix issue [#1](https://github.com/itay-grudev/SingleApplication/issues/1) * Improved documentation.
