EventIDE provides several built-in data types that are used for element properties. The built-in types are also available for coding in the snippets and developing the custom AddIns. The built-in types are not classes but plain .NET values types - it means they don't need a class constructor and disposing. On this page all built-in EventIDE types are listed with complete descriptions and code examples.

stColor type ¶

stColor is a data type for managing colors in EventIDE. stColor is a data struct that stores a single 32-bits ARGB value.

Fields ¶

stColor contains the following struct fields:

Field Name	Description	Value Type
.A	Defines a value for the Alpha channel (transparency). The valid range is 0..255.	Int32
.R	Defines a value for the Red channel. The valid range is 0..255.	Int32
.G	Defines a value for the Green channel. The valid range is 0..255.	Int32
.B	Defines a value for the Blue channel. The valid range is 0..255.	Int32
.Hue	Defines the color hue in HSB/HSV color space. The value has to be in the range 0..360. If the Saturation and Brightness have extreme values(e.g. 0 or 100) changes in the Hue field are ignored	Double
.Saturation	Defines the color saturation in HSB/HSV color space The value has to be in the range 0..100	Double
.Brightness	Defines the color saturation in HSB/HSV color space The value has to be in the range 0..100	Double
.Color	Represents the current value in System.Windows.Media.Color format	System.Windows.Media.Color
.GDIColor	Represents the current value in GDI+System.Drawing.Color format	System.Drawing.Color

GUI type editor ¶

stColor data type underlies a majority of color properties in EventIDE objects. The program provides an dedicated editor for stColor values.

Code examples ¶

 
// Declaration and initialization 

// declare a new stColor and initialize its value to the green
stColor MyColor;
MyColor.A=255;
MyColor.R=0;
MyColor.G=255;
MyColor.B=0;

// declare and initialize with the green color with an optional stColor constructors
stColor MyColor2=new stColor(0,255,0); 
stColor MyColor3=new stColor(255,0,255,0); 

// declare and initialize the blue color with functions and constants of GDI+ API
stColor MyColor3.GDIColor=Color.FromArgb(255,0,0,255);
stColor MyColor4.GDIColor=Color.Blue; 

// using stColor type in GDI+ drawing procedures
stColor RedColor=new stColor(127,0,0); 
Pen BluePen = new Pen(RedColor.GDIColor, 3);
Graphics.DrawRectangle(BluePen, 0,0,50,50);

// The following examples cause runtime errors because the field values have to be integers in the range 0..255
stColor MyColor=new stColor(0,256,0);  
stColor MyColor2;
MyColor2.R=-20;

clPoint ¶

clPoint is a data type for managing screen positions in EventIDE. clPoint is a data struct that stores a 2D screen position both in cartesian (units: pixels) and polar coordinates (units: visual degrees).

Fields ¶

clPoint contains the following struct fields:

Field Name	Description	Value Type
.X	Defines the X-Axis value (in pixels) relatively to left-top corner of the screen.	Int32
.Y	Defines the Y-Axis value (in pixels) relatively to left-top corner of the screen.	Int32
.R	Defines a distance (in visual degree) between the given point and the screen center- the radius in the polar coordinate system. The exact pixels/visual degree conversion depends on chosen screen settings for each experiment.	float/Single
.Theta	Defines a distance (in visual degree) between the given point and the screen center- the radius in the polar coordinate system. The exact pixels/visual degree conversion depends on chosen screen settings for each experiment.	float/Single

GUI type editor ¶
