TiObjectCanvas.GetDisplayXToPixelsX
TiObjectCanvas
Used to convert an X-coordinate display value to an X-coordinate pixel value
on the Object Canvas.
function GetDisplayXToPixelX(Value : Double) : Integer;
Description
Call the GetDisplayXToPixelX method to convert a Cartesian X-coordinate
display value to an upper left-hand corner 0,0 origin X-coordinate pixel value on the
Object Canvas. Since the Object canvas uses the Cartesian coordinate system
(where the default 0,0 origin is in the center of the component), this function
provides a way to convert between the upper-left-hand corner 0,0 pixel origin
that the Windows API and QT API use and the center 0,0 origin of the Object
Canvas Component.
Note: Basically this function converts the coordinate Cartesian Coordinate system
of the component to pixel values that you would get from other functions in
windows. If you need to convert a Y coordinate display value, see GetDisplayYToPixelsY.
Example
Delphi
Value := iComponent.GetDisplayXToPixelX(25.2);
C++ Builder
Value = iComponent->GetDisplayXToPixelX(25.2);
