| + | ===== Dynamic Colors ===== | ||
| + | The <Color>-Tag can be expaned to contain dynamic expressions for the color. | ||
| + | <code> | ||
| + | <Color Background="Transparent" Foreground="White"> | ||
| + | <BackgroundValue></BackgroundValue> | ||
| + | <ForegroundValue></ForegroundValue> | ||
| + | </Color> | ||
| + | </code> | ||
| + | If BackgroundValue/ForegroundValue tags are present the default values will be ignored and the given expressions will be evaluated. Expressions have to be in SPAD.neXt format (see custom expression) and will always be interpreted as a string. | ||
| + | |||
| + | To reference Gauge/Profile/Device scoped variables in the expression you can use the prefixes GAUGE: PROFILE: DEVICE: | ||
| + | |||
| + | Example: | ||
| + | <code> | ||
| + | <Color Background="Transparent" Foreground="White"> | ||
| + | <BackgroundValue>[GAUGE:MY_COOL_VARIABLE_NAME]</BackgroundValue> | ||
| + | <ForegroundValue>[DEVICE:MY_EVEN_COOLER_VARIABLE_NAME]</ForegroundValue> | ||
| + | </Color> | ||
| + | </code> | ||
| + | |||
| + | The expression can eiter return a [[https://docs.microsoft.com/en-us/dotnet/api/system.drawing.knowncolo|KnownColor]] or a hexadecimal value in form '#AARRGGBB' ([[https://en.wikipedia.org/wiki/RGBA_color_model#ARGB32|ARGB32]]) | ||
