Preconfiguration "Meter"

Creates the PmgCanvas object configured as meter Half-circle.

This preconfiguration can be activated when creating a new Pmg object and is included in the group: "/ Meter".

This object contains embedded PmgCanvas object named "Dynamic". It controls the movement of the device pointer by using the variable named "val". It is possible to connect it to the measured value by data binding.

In the parent PmgCanvas object there are variables title as meter name, min and max defining the value range of the meter. The values technolMin and technolMax differentiate the technological limits by color. The arcScale value defines the angle section where the scale is rendered. Additional configuaration variables are located in the context itself, in the section beginning with the USER VALUES comment.

Additional configuration variables are located at the beginning of context itself, or at the beginning of designer's method. The following items can be set:
- sUnit - measuring unit
- fontSize - description text size
- majTicks - number of main ticks of the scale
- minTicks - number of minor ticks between main ticks
- nDescPer - specifies the quantity of main segment descriptors (0 = no, 1 = each main, 2 = each second)
- bgColor1 and bgColor2 - the values define the background colors of the meter
- borderWidth - width of the meter border
These configurators can be set before the preconfiguration is created:
The name of created objectName (identifier) of the Pmg object. It is used for obtaining the Pmg object by the PmgObject.Items method.
This configurator sets the initial value of the Name property.
The maximum name length is 30 characters.
This is a system name, so it must contain only alphanumeric and must not contain any diacritics (i.e. national dependent characters), empty string, spaces and the first character must not be a number.
