LinkPanel

Construct an empty LinkPanel.

Gets or sets the nature of the link implementation.

Gets the LinkShape that represents the visual path of the Route of the Link.

Arrange the child elements of this panel and of any label nodes.

finalSize

Dynamically compute the desired angle of an element along a segment of the route.

elt

the UIElement being rotated

orient

the LabelOrientation declared for the element

angle

the angle of the segment of the route where the element is attached

戻り値: the intended angle for the element

Compute the offset to use in determining the position of a label.

elt

the label being positioned, either a child element of the LinkPanel or the VisualElement of a label Node

index

the segment of the link, or a negative value if the label should be at the MidPoint

segangle

the angle of the th segment, or the MidAngle

sz

the size of the label

labelangle

the angle at which the label is rotated, from calling Double)

戻り値: an offset that is rotated according to the angle of the segment; this will be added to the midpoint of the link or to the fractional point along the segment

Gets an element's alignment spot, which controls the point of the element that is positioned at a distance of the way along a particular segment of the route.

d

a child element of a LinkPanel

戻り値: The default value is Center.

Gets the fractional distance along a segment at which the element should be positioned.

d

a child element of a LinkPanel

戻り値: The default value is zero. For negative indexes, the fraction increases from zero to one as the point moves from the "to" end towards the "from" end.

Gets the Arrowhead on a Path, at the FromNode end.

d

a child element of a LinkPanel

戻り値: The default value is None, meaning there is no Arrowhead on the element.

Gets the size of the Arrowhead on an element, at the FromNode end, as a scale multiple of its base size.

d

a child element of a LinkPanel

戻り値: The default value is 1.0, indicating the base size defined in Generic.xaml.

Gets an element's segment index along the link's route.

d

a child element of a LinkPanel

戻り値: Zero identifies the segment closest to the "from" end of the route. Positive values identify segments further along the route. Negative values identify segments starting at the "to" end of the route; -1 is the last segment, -2 is the next to last, etc. If the index is not specified for an element, the LinkPanel will arrange it to be at the Route's MidPoint.

Gets whether a LinkShape is the primary stroke for the link.

Gets the distances from the fractional point of a link segment at which the element should be positioned.

d

a child element of a LinkPanel

戻り値: The default value is (0, 0). The offset distances are in model coordinates. The offset is rotated to the angle of the link segment. Positive X values result in the element being positioned farther along the link segment; negative values are closer. Positive Y values result in the element being positioned away from the link segment on the right side of the path; negative values go toward the left side.

Gets an element's intended rotation policy.

d

a child element of a LinkPanel

戻り値: The default value is None, meaning the element is not to be rotated.

Gets the Arrowhead on a Path, at the ToNode end.

d

a child element of a LinkPanel

戻り値: The default value is None, meaning there is no Arrowhead on the element.

Gets the size of the Arrowhead on an element, at the ToNode end, as a scale multiple of its base size.

d

a child element of a LinkPanel

戻り値: The default value is 1.0, indicating the base size defined in the xaml.

Returns whether an Arrowhead should be filled.

arrow

The Arrowhead which should or should not be filled.

戻り値: True if the Arrowhead should be filled.

Determine the size of the union of the bounds of the positioned and rotated child elements.

availableSize

Sets an element's alignment spot, which controls the point of the element that is positioned at a distance of the way along a particular segment of the route.

d

a child element of a LinkPanel

v

Sets the fractional distance along a segment at which the element should be positioned.

d

a child element of a LinkPanel

v

The fraction should be between zero and one, inclusive. For non-negative indexes, the fraction increases from zero to one as the point moves from the "from" end toward the "to" end. For negative indexes, the fraction increases from zero to one as the point moves from the "to" end towards the "from" end.

Sets the Arrowhead on a Path, at the FromNode end.

d

a child element of a LinkPanel

v

the constant of the Arrowhead enum to which FromArrowProperty is being set.

Sets the size of the Arrowhead on an element at the FromNode end as a scale multiple of its base size.

d

a child element of a LinkPanel

v

the scale factor. Acceptable values are real numbers between zero and infinity.

Sets an element's segment index along the link's route.

d

a child element of a LinkPanel

v

Zero identifies the segment closest to the "from" end of the route. Positive values identify segments further along the route. Negative values identify segments starting at the "to" end of the route; -1 is the last segment, -2 is the next to last, etc. If the index is not specified for an element, the LinkPanel will arrange it to be at the Route's MidPoint.

Sets whether a LinkShape is the primary stroke for the link.

Sets the distances from the fractional point of a link segment at which the element should be positioned.

d

a child element of a LinkPanel

v

The offset distances are in model coordinates. The offset is rotated to the angle of the link segment. Positive X values result in the element being positioned farther along the link segment; negative values are closer. Positive Y values result in the element being positioned away from the link segment on the right side of the path; negative values go toward the left side.

Sets an element's intended rotation policy.

d

a child element of a LinkPanel

v

Sets the Arrowhead on a Path, at the ToNode end.

d

a child element of a LinkPanel

v

the constant of the Arrowhead enum to which ToArrowProperty is being set.

Sets the size of the Arrowhead on an element, at the ToNode end, as a scale multiple of its base size.

d

a child element of a LinkPanel

v

the scale factor. Acceptable values are real numbers between zero and infinity.
