Assign(TPersistent)
|
Represents method Assign(TPersistent).
|
|
Change
|
Called when the position changes.
The Change method triggers an OnChange event.
|
|
DefineProperties(TFiler)
|
Provides methods to read and write unpublished data.
DefineProperties is implemented so that the position is written as a single string in the form file, not as separate X and Y values.
DefineProperties uses the methods of the filer passed as the Filer parameter to assign methods that can load and save the Point property.
|
|
Empty
|
Returns true if the position is at the origin (0, 0)
|
|
ReadPoint(TReader)
|
Reads the coordinates of a point from the given Reader.
ReadPoint transforms the string data from the TReader given as a parameter into TPointF properties and assigns them to the Point property.
|
|
Reflect(TRSVector)
|
Returns the reflection of the current vector across a specified line.
Use the Reflect function to obtain the reflection of the current position across the perpendicular on the point given as parameter.
|
|
SetPointNoChange(TRSPoint)
|
Sets the position without triggering an OnChange event.
|
|
WritePoint(TWriter)
|
Writes the properties of the current Point into the given TWriter object.
WritePoint transforms the properties of Point into a string and writes the result in the TWriter given as a parameter.
