Name |
Gets the name of this document node. Null is returned if the name is not set or unknown.
The set accessor will for most nodes throw a InvalidOperationException, since the name can only be set on IProjectItems.
(Inherited from SuspendableDocumentNodeBase) | |
ParentCollection | (Inherited from PlotItem) | |
ParentObject |
Gets/sets the parent object this instance belongs to.
(Inherited from SuspendableDocumentNodeBase) | |
Style | ||
StyleObject | (Overrides PlotItemStyleObject) |
Name | Description | |
---|---|---|
AccumulateChangeData | (Inherited from SuspendableDocumentNodeWithSetOfEventArgs) | |
AccumulatedChangeData_SetBackAfterResumeAndSuspend | (Inherited from SuspendableDocumentNodeWithSetOfEventArgs) | |
AccumulatedEventData_Clear |
Clears the accumulated event data.
(Inherited from SuspendableDocumentNodeWithSetOfEventArgs) | |
AccumulatedEventData_HasZeroOrOneEventArg |
Determines whether there is no or only one single event arg accumulated. If this is the case, the return value is true. If there is one event arg accumulated, it is returned in the argument singleEventArg.
The return value is false if there is more than one event arg accumulated. In this case the singleEventArg is null on return, and the calling function should use AccumulatedEventData to
enumerate all accumulated event args.
(Inherited from SuspendableDocumentNodeWithSetOfEventArgs) | |
ApplyGroupStyles | (Overrides PlotItemApplyGroupStyles(PlotGroupStyleCollection)) | |
ChildCloneFromT |
Clones a node that is intended to use as child node of this instance (e.g. in collections). Consider using ChildCloneToMemberT(T, T) instead if the child node
is stored in a member of this instance.
(Inherited from SuspendableDocumentNode) | |
ChildCloneToMemberT |
Sets a member variable that holds a child with a cloned instance of another variable.
If an old instance member (provided in myChild exists and can not be used, it is disposed first.
The node is then cloned using System.ICloneable. The resulting node's ParentObject
is then set to this instance in order to maintain the parent-child relationship.
(Inherited from SuspendableDocumentNode) | |
ChildCloneToMemberAltT |
Set a member variable that holds a child node of this instance. The child node may or may not implement IDocumentLeafNode.
The value to set may or may not implement ICloneable. If it implements ICloneable, then the member variable is
set to a clone of the value. Otherwise, the member variable is set directly with the value.
It helps to ensure the correct order: first, the child node is set to the new instance and then the old child node is disposed.
(Inherited from SuspendableDocumentNode) | |
ChildCopyToMemberT |
Copies a document node from another source into a member of this instance.
If an old instance member (provided in myChild exists and can not be used, it is disposed first.
The node is then copied using either Main.ICopyFrom or System.ICloneable. The resulting node's ParentObject
is then set to this instance in order to maintain the parent-child relationship.
(Inherited from SuspendableDocumentNode) | |
ChildCopyToMemberOrCreateNewT |
Copies a document node from another source into a member of this instance.
If an old instance member (provided in myChild exists and can not be used, it is disposed first.
If the node is not null, the node is then copied using either Main.ICopyFrom or System.ICloneable. If the node is null, a new node is created using the provided generation function.
The resulting node's ParentObject is then set to this instance in order to maintain the parent-child relationship.
(Inherited from SuspendableDocumentNode) | |
ChildDisposeMemberT |
Helper function to dispose a child node of this instance. It helps to ensure the correct order: first, the child node is set to null and only then the child node is disposed.
(Inherited from SuspendableDocumentNodeBase) | |
ChildSetMemberT |
Set a member variable that holds a child node of this instance. It helps to ensure the correct order: first, the child node is set to the new instance and then the old child node is disposed.
(Inherited from SuspendableDocumentNode) | |
ChildSetMemberAltT |
Set a member variable that holds a child node of this instance. The child node may or may not implement IDocumentLeafNode.
It helps to ensure the correct order: first, the child node is set to the new instance and then the old child node is disposed.

(Inherited from SuspendableDocumentNodeBase) | |
EhSelfTunnelingEventHappened(TunnelingEventArgs, Boolean) |
Is called by this instance if a tunneling event happened into this instance.
The tunneling event triggers the TunneledEvent and is - depending on the provided parameter - also distributed to all childs of this instance.

GetPixelwiseImage(Bitmap) | Gets a pixelwise image of the data. Horizontal or vertical axes are not taken into accout. The horizontal dimension of the image is associated with the columns of the data table. The vertical dimension of the image is associated with the rows of the data table. | |
GetType | Gets the Type of the current instance. (Inherited from Object) | |
HandleHighPriorityChildChangeCases |
Handles the case when a child changes, and a reaction is neccessary independently on the suspend state of the table. It is used here to change the event args
coming from the StyleObject to PlotItemStyleChangedEventArgs and event args coming from the data object to PlotItemDataChangedEventArgs.
(Inherited from PlotItem) | |
HandleLowPriorityChildChangeCases |
Processes the event args e when this object is not suspended. This function serves two purposes:
i) updating some cached data of this object by processing the event args of the child,
and ii) optional transforming the event args, for instance to a new type, which afterwards is send to the parent and is used as event args in the [E:Changed] event of this object.
The transformed event args is not used if this object is suspended (in this case the original event args is used).
(Inherited from SuspendableDocumentNode) | |
HitTest |
Test wether the mouse hits a plot item. The default implementation here returns null.
If you want to have a reaction on mouse click on a curve, implement this function.
(Inherited from PlotItem) | |
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) | |
MergeXBoundsInto | ||
MergeYBoundsInto | ||
NotifyChildrenTunnelingEventHappened |
Notifies the child nodes of this instance that a tunneling event has happened.
(Inherited from SuspendableDocumentNode) | |
OnAboutToBeResumed |
Is called when the suspend level is still 1 (one), but is about to fall to zero, i.e. shortly before the call to OnResume(Int32). This function is not called before OnResumeSilently(Int32)!
(Inherited from SuspendableDocumentNode) | |
OnChanged | (Overrides SuspendableDocumentNodeBaseOnChanged(EventArgs)) | |
OnResume |
Is called when the object is resumed, i.e. change notifications are allowed again. During the execution of this function, the [P:IsResumeInProgress] property will return true to indicate that the resume is currently in progress.
(Inherited from SuspendableDocumentNode) | |
OnResumeSilently |
Is called when the suspend level falls down from 1 to zero by a call to ResumeSilently.
This implementation disarma the suspendTokens of the childs of this object, deletes any accumulated events, and does not send any change event to the parent or the listeners of the Change event.
(Inherited from SuspendableDocumentNode) | |
OnSuspended |
Called when the suspend level has just gone from 0 to 1, i.e. the object was suspended.
(Inherited from SuspendableDocumentNode) | |
OnTunnelingEvent |
Fires the TunneledEvent event.
(Inherited from SuspendableDocumentNodeBase) | |
Paint | (Overrides PlotItemPaint(Graphics, IPaintContext, IPlotArea, IGPlotItem, IGPlotItem)) | |
PaintPostprocessing |
Called after painting has finished. Can be used to release resources. Must be overridden by a derived class.
(Inherited from PlotItem) | |
PaintPreprocessing |
Called before painting takes place.
(Inherited from PlotItem) | |
PaintSymbol |
Paints a symbol for this plot item for use in a legend.
(Inherited from PlotItem) | |
PrepareGroupStyles | (Overrides PlotItemPrepareGroupStyles(PlotGroupStyleCollection, IPlotArea)) | |
PrepareScales |
This routine ensures that the plot item updates all its cached data and send the appropriate
events if something has changed. Called before the layer paint routine paints the axes because
it must be ensured that the axes are scaled correctly before the plots are painted.
(Overrides PlotItemPrepareScales(IPlotArea)) | |
Resume(ISuspendToken) |
Resumes changed events by calling Resume for the provided suspend token, and setting the reference to the suspend token to null.
If Event data were accumulated during the suspended state, a changed event is triggered for each event data.
(Inherited from SuspendableDocumentNodeBase) | |
Resume(ISuspendToken, EventFiring) |
Resumes changed events, either with taking the accumulated event data into account (see Resume(ISuspendToken)) or discarding the accumulated event data (see ResumeSilently(ISuspendToken),
depending on the provided argument eventFiring.
(Inherited from SuspendableDocumentNodeBase) | |
ResumeCompleteTemporarily |
Resumes the object completely for only a short time. Thus, if object was suspended before, it will be suspended again when the function returns.
(Inherited from SuspendableDocumentNode) | |
ResumeCompleteTemporarilyGetToken |
Resumes the object completely for the time the returned token is referenced and not disposed.
The return value is a token that had 'absorbed' the suspend count of the object, resulting in the suspend count
of the object dropped to 0 (zero). When the returned token is finally disposed, the suspend count of the object is increased again by the 'absorbed' suspend count.
(Inherited from SuspendableDocumentNode) | |
ResumeSilently |
Resumes changed events by calling Resume for the provided suspend token, and setting the reference to the suspend token to null.
All event data accumulated during the suspended state are discarded, and thus no change event is triggered even if the instance has changed during the suspended state.
(Inherited from SuspendableDocumentNodeBase) | |
SetDisposeInProgress |
Sets the flag that dispose is in progress for this node and all child nodes recursively.
(Inherited from SuspendableDocumentNode) | |
SetMemberAndRaiseSelfChangedT(NullableT, NullableT) |
Sets a member variable of this instance and raise a change event with Empty if the new value is different from the old value.
The comparison is done using the IEquatableT interface of the member variable.
Note: to set members that implement IDocumentNode please use the Child... functions.
(Inherited from SuspendableDocumentNodeBase) | |
SetMemberAndRaiseSelfChangedT(T, T) |
Sets a member variable of this instance and raise a change event with Empty if the new value is different from the old value.
The comparison is done using the IEquatableT interface of the member variable.
Note: to set members that implement IDocumentNode please use the Child... functions.
(Inherited from SuspendableDocumentNodeBase) | |
SetMemberEnumAndRaiseSelfChangedT |
Sets a member variable (which is an Enum) of this instance and raise a change event with Empty if the new value is different from the old value.
The comparison is done using the IEquatableT interface of the member variable.
Note: to set members that implement IDocumentNode please use the Child... functions.
(Inherited from SuspendableDocumentNodeBase) | |
SetPlotStyleFromTemplate |
