Preconfiguration "Circular meter"
Creates the
PmgCanvas object configured as circular meter.
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 min and
max defining the value range of the device. Additional configuration 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
- sTextSize - description text size
- majTicks - number of main scale ticks
- minTicks - number of minor scale ticks between main ticks
- nTechnolMin and nTechnolMax - technological limits setup (if the entered values are identical, then no limits are rendered)
- bgColor1 and bgColor2 - the values define the background colors of the device
These configurators can be set before the preconfiguration is created:
| Object name | Name (identifier) of the Pmg object. It is used to obtain 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, empty string, spaces and the first character must not be a number. |
