CustomPath¶

Qualified name: delphifmx.CustomPath

class CustomPath¶

Bases: Shape

TCustomPath is the base class for all 2D path-type shapes representing groups of connected curves and lines. TCustomPath renders the path Data graphics with the Paint method. Paint scales and positions the path graphics according to the WrapMode parameter. Paint draws the path contour and fills the background using the drawing pen and brush with the properties, color, and opacity defined by the Stroke and Fill properties of the TCustomPath object.

AbsoluteToLocal()¶: Converts the screen coordinates of a specified point on the screen to client coordinates.

BringToFront()¶: Puts the control in front of all other controls in its parent control.

CanFocus()¶: Indicates whether a control can receive focus.

Controls¶: Returns an iterator over contained controls

ControlsCount¶: Returns the count of contained controls

Data¶

Specifies the SVG data used to build graphic shapes. The Data property supports only a comma-separated list of instructions defined for the d attribute of the path element in SVG 1.0. In SVG 1.0, the d attribute contains the moveto, line, curve, arc, and closepath instructions. All instructions are expressed as one character (for example, a moveto is expressed as an M). For more information, see Scalable Vector Graphics (SVG) 1.0 Specification.

Example To clarify, consider the following code snippets that specify the SVG instructions at run time:

Delphi:

Path1.Data.Data := ‘M 1,0, L 2,1, L 1,2, L 0,1, L 1,0’;

C++Builder:

Path1->Data->Data = “M 1,0, L 2,1, L 1,2, L 0,1, L 1,0”;

An application that uses the above mentioned SVG instructions displays a rhomb:

Type:: PathData

IsFocused¶: Determines whether the control has input focus.

LocalToAbsolute()¶: Translates a given point from client area coordinates to global screen coordinates.

PointInObject(X: float, Y: float) → bool¶

Checks whether the specified point belongs to the path Data of the TCustomPath object. PointInObject calls the FMX.Graphics.TCanvas.PtInPath method of the TCanvas object to check whether the specified point belongs to the path Data of the TCustomPath object. X and Y are absolute pixel coordinates of the point to be checked:

X is the x-coordinate. Y is the y-coordinate.

Position¶: Returns an access to the position of the control inside its parent

PrepareForPaint()¶: Prepares the current control for painting.

Repaint()¶: Forces the control to repaint its image on the screen.

ResetFocus()¶: Removes the focus from a control of from any children of the control.

SendToBack()¶: Puts a windowed control behind all other windowed controls, or puts a non-windowed control behind all other non-windowed controls.

SetBounds(Left, Top, Width, Height)¶: Sets the Left, Top, Width, and Height properties all at once.

SetFocus()¶: Gives the input focus to the control.

Visible¶: Returns/Sets the Control Visibility

WrapMode¶

Specifies whether and how to resize, replicate, and position the graphical path representation for painting the area. The WrapMode property should be one of the constants defined in the TPathWrapMode type:

Stretch–stretches the path representation to fill the entire area. Default. Original–keeps the original path size. Fit–resizes the path representation (keeping proportions) to best fit the area. Tile–renders the path representation repeatedly to tile the area.
