Qt Solutions Component: Service

The QtService component is useful for developing Windows services and Unix daemons.
wangwenx190: Some modifications were made to meet my personal needs.

Version history

2.0

• Reimplemented for Qt 4 with improved API.

2.1

• More feedback while installing / uninstalling.
• Unix: Documentation about installing service improved.
• Windows: Added account and password arguments to install().
• Windows: Report status correcty when stopping through the controller.
• Windows: Send command IDs correctly.

2.2

• Unix: logMessage() works properly with '%' characters.
• Windows: Dependency on the QtGui library removed.

2.3

• Unix: Using QProcess in a service no longer leaves zombie processes around.
• Windows: Place controller's receiver object in proper thread. (makes QtService work with Qt 4.2).
• Compilation fixes for MinGW.

2.4

• Windows: Do net require Administrator privileges just to start service.
• Improved command-line help text.
• Document the caveats of using GUI services, including that Vista does not support it.
• Added -w(ait) argument to controller example.
