[Engine-devel] UI plugins crash course part two (for plugin developers)

Hi guys, this is a follow-up on the quick "crash course" for writing simple UI plugin. Before we proceed, please keep in mind that: - api.register() must be called exactly once, subsequent calls "overwrite" previous ones - api.register() must be called before api.ready(), otherwise your plugin will not work - you don't have to define all supported event handler functions in api.register(), just the ones your plugin is interested in (e.g. UiInit) Level 4 - Let's make things configurable ======================================== 1. Specify default plugin configuration (optional) $ vim /usr/share/ovirt-engine/ui-plugins/hello-ui-world.json [hello-ui-world.json] ... "config": { "testLink": "http://www.example.com/" } ... [/hello-ui-world.json] 2. Override default plugin configuration (optional) $ mkdir -p /etc/ovirt-engine/ui-plugins $ vim /etc/ovirt-engine/ui-plugins/hello-ui-world-config.json [hello-ui-world-config.json] { "config": { "testLink": "http://www.another-example.com/" } } [/hello-ui-world-config.json] 3. Use plugin configuration that has been merged together $ vim /usr/share/ovirt-engine/ui-plugins/hello-world-files/start.html [start.html] ... # Anywhere within event handler function code (e.g. UiInit) var conf = api.configObject(); api.showDialog('Test Dialog', conf.testLink, 600, 400); ... [/start.html] Regards, Vojtech
