e2MDB – Skinner: optional panels
An optional panel should load only when both modules exist and the necessary functions are enabled. The example checks .py and .pyc. Keep ordinary picon/text presentation outside the optional panel in the complete InfoBar.
<panel name="MyE2MDBInfoBar" condition=" (isfile('/usr/lib/enigma2/python/Plugins/Extensions/e2MDB/plugin.py') or isfile('/usr/lib/enigma2/python/Plugins/Extensions/e2MDB/plugin.pyc')) and (isfile('/usr/lib/enigma2/python/Components/Converter/E2MDBEventInfo.py') or isfile('/usr/lib/enigma2/python/Components/Converter/E2MDBEventInfo.pyc')) and config.plugins.e2mdb.enableDatabase.value and config.plugins.e2mdb.epgMetaEnabled.value and config.plugins.e2mdb.epgInfoBarEnabled.value" />MyE2MDBInfoBar is a panel defined by the skin. It must exist under that name and can contain the widgets from covers and text. This supplements a base view without requiring a plugin modification.
Two complete variants
Section titled “Two complete variants”When the whole layout changes, define two panels, for example MyBase_InfoBar and MyMedia_InfoBar. Use the positive condition for the media panel and the identical condition with the skin parser’s leading exclamation-mark inversion for the base panel. Both sides must use the same complete condition.
For channel selection, replace the last switch with config.plugins.e2mdb.epgChannelSelectionEnabled.value. For other screens, check only the switches required by their actual integration. A media EventView is not a live-TV InfoBar.
Both panel calls in XML
Section titled “Both panel calls in XML”Place both calls in the same InfoBar screen. Define MyBase_InfoBar and MyMedia_InfoBar in the skin; the media definition contains the widgets from Appendix E. The exclamation mark is the first character of the attribute value. The base view remains active when the plugin is absent or integration is disabled.
<panel name="MyBase_InfoBar" condition="!(isfile('/usr/lib/enigma2/python/Plugins/Extensions/e2MDB/plugin.py') or isfile('/usr/lib/enigma2/python/Plugins/Extensions/e2MDB/plugin.pyc')) and (isfile('/usr/lib/enigma2/python/Components/Converter/E2MDBEventInfo.py') or isfile('/usr/lib/enigma2/python/Components/Converter/E2MDBEventInfo.pyc')) and config.plugins.e2mdb.enableDatabase.value and config.plugins.e2mdb.epgMetaEnabled.value and config.plugins.e2mdb.epgInfoBarEnabled.value" />
<panel name="MyMedia_InfoBar" condition="(isfile('/usr/lib/enigma2/python/Plugins/Extensions/e2MDB/plugin.py') or isfile('/usr/lib/enigma2/python/Plugins/Extensions/e2MDB/plugin.pyc')) and (isfile('/usr/lib/enigma2/python/Components/Converter/E2MDBEventInfo.py') or isfile('/usr/lib/enigma2/python/Components/Converter/E2MDBEventInfo.pyc')) and config.plugins.e2mdb.enableDatabase.value and config.plugins.e2mdb.epgMetaEnabled.value and config.plugins.e2mdb.epgInfoBarEnabled.value" />Availability and current artwork are different checks
Section titled “Availability and current artwork are different checks”| Check | Purpose |
|---|---|
| Plugin and converter exist | Before loading the optional panel, avoid imports of missing modules. |
| Relevant function enabled | Decide whether the media layout is wanted and available. |
| HasCover / HasBackdrop | React to the current event’s actual image data, for example to show a background. |
| Event changes to an empty source | Clear the previous image and text until new data is available. |
HasMetadata does not guarantee that artwork is ready or provider lookup succeeded. Check the specific image or text field you intend to display.
