# KDSingleApplication
`KDSingleApplication` is a helper class for single-instance policy applications
written by [KDAB](https://www.kdab.com).
## Usage
Currently the documentation is woefully lacking, but see the examples or tests
for inspiration. Basically it involves:
1. Create a `Q(Core|Gui)Application` object.
2. Create a `KDSingleApplication` object.
3. Check if the current instance is *primary* (or "master") or
*secondary* (or "slave") by calling `isPrimaryInstance`:
* the *primary* instance needs to listen from messages coming from the
secondary instances, by connecting a slot to the `messageReceived` signal;
* the *secondary* instances can send messages to the primary instance
by calling `sendMessage`.
See [INSTALL.txt](INSTALL.txt) for installation instructions using CMake.
