Changes

Multi snaps

We are now able to activate multiple snap modes simultaneousely. We can see in the picture that, when multiple modes are active at the same time, we have multiple possible snaps location depending ont he cursor position.

Snap modes choices

The consuming app can now choose what snap modes are available in their app. Ex, Bisector option has been filtered out.

Testing

2 unit tests are added to check the functionnality.

• Ensuring at least one snap mode active at all times.
• Validating if we are able to select what snap modes are available in the app.

Usage

// Remove Bisector from the modes available.
const snapModes = Object.values(SnapMode).filter(snapMode => snapMode !== SnapMode.Bisector) as SnapMode[];

// Register a status bar item that has the custom snap modes. 
UiItemsManager.register({
    id: "customStatusBarSnapModes",
    getStatusBarItems: () => [
        StatusBarItemUtilities.createCustomItem({
            id: "booster.SnapMode",
            section: StatusBarSection.Center,
            content: <SnapModeField snapModes={snapModes} />
        })
    ]
})
