Variant
toBool() [Variant class]
Returns value of the variant to an bool (boolean, true or false), converting the type if necessary. The original value is left unchanged.
| Source | Result |
|---|---|
| bool | unchanged |
| numeric | zero (0) → false, non-zero → true |
| String | false → false, 'true' → "true" |
| other | conversion fails |
There are two overloads, one that takes an ok parameter passed by reference, which is filled in as
true if the data is already this type or can be converted.
// PROTOTYPES
bool toBool() const;
bool toBool(bool& ok) const;
