CalloutPanel

Qualified name: delphifmx.CalloutPanel

class CalloutPanel

Bases: Panel

A container for extra information relevant to another item, with a visual indicator pointing to that item. A call-out often takes the form of a pull-quote, in which a particular snippet of text in a document is duplicated to attract attention: in a larger size, with a different typeface, in a colored box, with stylized quote marks, etc. With illustrations, boxed text will refer to different elements of interest, and each box will be drawn with extra lines that point to its element. Use TCalloutPanel to create a call-out for elements in the user interface. The call-out may be transient, like a heavy-duty tool tip. The default style is a TCalloutRectangle, a rectangle with a triangular “peak” on one of four sides. A custom style that is not a TCalloutRectangle at the root should contain one with the ResourceName “background”, so that the size and position properties for the triangle can be applied. The bounds of the control includes that peak: the longer the peak, the shorter the rectangle, and vice versa.

AdjustSizeValue

Updates the width and height of this control according to its current style

AdjustType

Determines if and how the width and height of this control should be modified to take the fixed space dictated by the style of this control

ApplyStyleLookup()

Gets and applies the style of a TStyledControl.

AutoTranslate

Specifies whether the control’s text should be translated

CalloutLength

The length of the visual element that points at the area of interest. By default, TCalloutPanel uses TCalloutRectangle, which renders its callout pointer as an isosceles triangle on one of its sides. CalloutLength is the height of this triangle. The triangle is included in the bounding rectangle ShapeRect of the TCalloutPanel object; therefore, the longer CalloutLength is, the smaller the height (or width) of the callout panel itself is, and vice versa. Keeping the bounding rectangle the same size while changing the length of the triangle CalloutLength requires changing the height or width of the callout panel TCalloutPanel itself, depending on which side the triangle appears.

Type:

float

CalloutOffset

The position of the callout pointer, relative to the center or edges of the side on which it appears. By default, TCalloutPanel uses TCalloutRectangle, which renders its callout pointer–visual element that points at the area of interest–as an isosceles triangle on one of its sides. The CalloutPosition defines the side on which the triangle appears. CalloutOffset is the offset of the callout pointer implemented according to the following conditions:

If CalloutOffset is zero, then the callout pointer is centered on the specified side. If CalloutOffset is positive, then the closest point to a corner of the callout pointer has the CalloutOffset offset on the following sides: Top–offset to the right from the upper-left corner. Left–offset to the bottom from the upper-left corner. Right–offset to the bottom from the upper-right corner. Bottom–offset to the right from the lower-left corner. If CalloutOffset is negative, then the closest point to a corner of the callout pointer has the CalloutOffset offset on the following sides: Top–offset to the left from the upper-right corner. Left–offset to the top from the lower-left corner. Right–offset to the top from the lower-right corner. Bottom–offset to the left from the lower-right corner.

Type:

float

CalloutPosition

Defines the side where the callout pointer appears. Set CalloutPosition to one of the Top, Left, Bottom, or Right constants predefined in TCalloutPosition to define the side on which the callout pointer should appear. By default, the callout pointer appears on the top side CalloutPosition = Top. By default, TCalloutPanel uses TCalloutRectangle, which renders its callout pointer–the visual element that points at the area of interest–as an isosceles triangle on one of its four sides.

Type:

CalloutPosition

CalloutRectangle

A reference to a TCalloutRectangle style object.

Type:

CalloutRectangle

CalloutWidth

The width of the visual element that points at the area of interest. By default, TCalloutPanel uses TCalloutRectangle, which renders its callout pointer as an isosceles triangle on one of its sides. CalloutWidth is the length of the base of the triangle.

Type:

float
