void setMin(float min)
void setMax(float max)
A single element of a property tree, with a name, value, description, and possibly children...
Definition: property.h:100
virtual float getFloat() const
bool multiply(float factor)
Multiply the property value by the given factor.
Property specialized to enforce floating point max/min.
virtual bool setValue(const QVariant &new_value)
Set the new value for this property. Returns true if the new value is different from the old value...
bool add(float delta)
Add the given delta to the property value.
bool setFloat(float new_value)
Float-typed "SLOT" version of setValue().
description
def default_value(type)
int min(int a, int b)
virtual QVariant getValue() const
Return the value of this Property as a QVariant. If the value has never been set, an invalid QVariant...
