Module: Panel

Overview​

The default LayoutTemplate has panels on the left and right sides, however one could make a template with panels at the top or bottom and make extensions with panels intended for such slots.

An extension can register a Panel Module by defining a getPanelModule method. The panel module provides the ability to define menuOptions and components that can be used by the consuming application. components are React Components that can be displayed in the consuming application's "Panel" Component.

panel-module-v3

The menuOptions's target key, points to a registered components's id. A defaultContext is applied to all menuOptions; however, each menuOption can optionally provide its own context value.

The getPanelModule receives an object containing the ExtensionManager's associated ServicesManager and CommandsManager.

An extension can also trigger to activate/open a panel via the PanelService - either by explicitly calling PanelService.activatePanel or triggering panel activation when some other event fires.

import PanelMeasurementTable from './PanelMeasurementTable.js';

function getPanelModule({
commandsManager,
extensionManager,
servicesManager,
}) {
const wrappedMeasurementPanel = () => {
return (
<PanelMeasurementTable
commandsManager={commandsManager}
servicesManager={servicesManager}
/>
);
};

return [
{
name: 'measure',
iconName: 'list-bullets',
iconLabel: 'Measure',
label: 'Measurements',
isDisabled: studies => {}, // optional
component: wrappedMeasurementPanel,
},
];
}

Consuming Panels Inside Modes​

As explained earlier, extensions make the functionalities and components available and modes utilize them to build an app. So, as seen above, we are not actually defining which side the panel should be opened. Our extension is providing the component with its.

New: You can easily add multiple panels to the left/right side of the viewer using the mode configuration. As seen below, the leftPanels and rightPanels accept an Array of the IDs. The mode configuration also allows for either (or both) side panels to be closed by default. In the code below, the right panel is closed by default. The mode can optionally add event triggers to the PanelService that when fired will cause a side panel that was defaulted closed to open. In the code below, the right side panel, that contains the trackedMeasurements panel, is triggered to open when a measurement is added. Note that once a default closed side panel has been opened once, only a PanelService.EVENTS.ACTIVATE_PANEL event with forceActive === true will cause it open (again).

_activatePanelTriggersSubscriptions = [];
},
extensions: extensionDependencies
};
}

const mode = {
id,
modeFactory,
extensionDependencies,
};

export default mode;
note

You can stack multiple panel components on top of each other by providing an array of panel components in the rightPanels or leftPanels properties.

For instance we can use

rightPanels: [[dicomSeg.panel, tracked.measurements], [dicomSeg.panel, tracked.measurements]]

This will result in two panels, one with dicomSeg.panel and tracked.measurements and the other with dicomSeg.panel and tracked.measurements stacked on top of each other.
