Member Function Documentation

getTextFromValue()

String juce::ColourComponentSlider::getTextFromValue ( double  value )

overridevirtual

Turns the slider's current value into a text string.

Subclasses can override this to customise the formatting of the text-entry box.

The default implementation just turns the value into a string, using a number of decimal places based on the range interval. If a suffix string has been set using setTextValueSuffix(), this will be appended to the text.

getValueFromText

Reimplemented from juce::Slider.

getValueFromText()

double juce::ColourComponentSlider::getValueFromText ( const String &  text )

overridevirtual

Subclasses can override this to convert a text string to a value.

When the user enters something into the text-entry box, this method is called to convert it to a value. The default implementation just tries to convert it to a double.
