Interaction principles
Dimming of objects
Texts are dimmed by changing the color of the text. Normally the text has
foreground color (-3). The alternative color, that is the dimmed color should be 4.
The condition for using the alternative color should be NOT EnableName.
The project constant cColors.Disable function can be used for dimming the objects.
If the operator window has an input field (interaction object) for a physical value,
this input field usually is preceded by a text presenting the name of the quantity, and
succeeded by a text presenting the unit of the quantity. If the input field is disabled,
both the preceding and succeeding texts should be dimmed. Static texts and text
objects that present values that are not changeable from the user window should not
be dimmed. Icons that cover interaction objects should always be dimmed if the
interaction object is disabled.
