```

## Constructors

- [GH_Timer](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/ctor.md)

## Properties

- [AllowModeSwitching](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/allowmodeswitching.md): Override this property and return false to disable switching between manual and scheduled modes.
- [AllowTargetLocking](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/allowtargetlocking.md): Override this property and return false to disable target locking UI.
- [ComponentGuid](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/componentguid.md)
- [DisplayIcon](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/displayicon.md): Override this property and return true to include the icon in the attributes.
- [DisplayUserName](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/displayusername.md): Override this property and return false to not include the user name in the attributes.
- [Exposure](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/exposure.md)
- [GlobalTimerBlock](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/globaltimerblock.md): (static) Gets the global timer block state.
- [Icon](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/icon.md)
- [IconCapableUI](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/iconcapableui.md)
- [InstanceDescription](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/instancedescription.md)
- [Interval](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/interval.md): Gets or sets the interval (in milliseconds between timer ticks). Any interval less than or equal to zero results in a manual timer.
- [IntervalString](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/intervalstring.md)
- [IsDataProvider](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/isdataprovider.md)
- [LockTargets](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/locktargets.md): Gets or sets whether the target objects ought to be locked while not triggered by this timer. This property does not itself perform any locking/unlocking, that is the responsibility of the caller.
- [Manual](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/manual.md): Gets whether updates must be triggered manually or whether they are automatically scheduled. Negative interval values imply a manual trigger.
- [TargetCount](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/targetcount.md): Gets the number of targets directly specified by this trigger.
- [Targets](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/targets.md): Gets the targets directly specified by this trigger.
- [TargetsRecursive](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/targetsrecursive.md): Gets the target specified by this trigger, and by any other trigger which is referenced by this trigger.
- [TimerComponentID](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/timercomponentid.md): (static)

## Methods

- [AddTarget](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/addtarget.md): (2 overloads)
- [AppendAdditionalMenuItems](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/appendadditionalmenuitems.md)
- [AppendMenuItems](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/appendmenuitems.md)
- [CleanTargetList](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/cleantargetlist.md): Remove all targets which can no longer be resolved. You typically don't want to call this as objects may have been deleted but may be re-instated via UNDO again. There's no real harm in having 'dirty' targets.
- [CollectData](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/collectdata.md)

- [EnsureBlockIcon](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/ensureblockicon.md): (static)
- [ExpireTargets](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/expiretargets.md): (2 overloads) Expire all target objects, but do not start a new solution.
- [HtmlHelp_Source](https://developer.rhino3d.com/api/gh1/type/grasshopper.kernel.special.gh-timer/htmlhelp-source.md)
