Returns the number of FlowElement children that this FlowGroupElement object has.

Base class - invoking new FlowGroupElement() throws an error exception.

Appends a child FlowElement object. The new child is added to the end of the children list.

Parameters

Adds a child FlowElement object at the specified index position.

Parameters

Given a relative text position, find the index of the first child FlowElement that contains relative position. More than one child can contain relative position because of zero length FlowElements.

Examine the children to find the FlowElement that contains the relative position. The supplied relative position is relative to this FlowElement.

Parameters

Given a relative text position, find the leaf element that contains the position.

Looks down the flow element hierarchy to find the element that is the FlowLeafElement containing the specified position. The specified position is relative to this FlowElement object.

Parameters

Returns the FlowElement child at the specified index.

Parameters

Searches in children for the specified FlowElement object and returns its index position.

Parameters

Returns the first FlowLeafElement descendant of this element.

Returns the last FlowLeafElement descendent of this element.

Removes the specified child FlowElement object.

Parameters

Removes a child FlowElement object at the specified index position.

Parameters

Replaces child elements in the group with the specified new elements. Use the beginChildIndex and endChildIndex parameters to govern the operation as follows:

• To delete elements, do not pass any replacement elements.
• To insert elements, pass the same value for beginChildIndex and endChildIndex . The new elements is inserted before the specified index.
• To append elements, pass numChildren for beginChildIndex and endChildIndex .

Otherwise, this method replaces the specified elements, starting with the element at beginChildIndex and up to but not including endChildIndex .

Splits this object at the position specified by the childIndex parameter. Creates a shallow copy of this object and adds it to the parent after this object. Moves elements following childIndex into the copy.

Parameters

Splits this object at the position specified by the relativePosition parameter, where the relative position is a relative text position in this element.

Parameters
