In qt 4.5, is it possible to have resources in a statically linked plugin?

Question

I have a custom QT plugin module that has embedded resources. I want to statically link this plugin with an application:

LIBS += -lstatic_plugin_with_resources

In the application I am using the Q_IMPORT_PLUGIN() macro, which allows the application to use the plugin; however the plugin can not access its embedded resources.

Using the plugin as a shared library does work.

Answer 1

It is possible. In the application you need to explicitly initialize the resources that are contained in the static plugin.

This is accomplished by calling the Q_INIT_RESOURCE(resource_base_name), where resource_base_name is the base name of the .qrc file that specifies the resources. This should probably be called in main() or at application startup. Optionally you can call Q_CLEANUP_RESOURCE() if the plugin is no longer being used.

See the last section of the QT 4.5 resource doc. Also see the documentation for Q_INIT_RESOURCE.

This worked for me on the linux version of QT 4.5.
