<h2>Detailed Description</h2>
|
|
<p>The QtDoublePropertyManager provides and manages double properties.</p>
|
|
<p>A double property has a current value, and a range specifying the valid values. The range is defined by a minimum and a maximum value.</p>
|
|
<p>The property's value and range can be retrieved using the <a href="qtdoublepropertymanager.html#value">value</a>(), <a href="qtdoublepropertymanager.html#minimum">minimum</a>() and <a href="qtdoublepropertymanager.html#maximum">maximum</a>() functions, and can be set using the <a href="qtdoublepropertymanager.html#setValue">setValue</a>(), <a href="qtdoublepropertymanager.html#setMinimum">setMinimum</a>() and <a href="qtdoublepropertymanager.html#setMaximum">setMaximum</a>() slots. Alternatively, the range can be defined in one go using the <a href="qtdoublepropertymanager.html#setRange">setRange</a>() slot.</p>
|
|
<p>In addition, QtDoublePropertyManager provides the <a href="qtdoublepropertymanager.html#valueChanged">valueChanged</a>() signal which is emitted whenever a property created by this manager changes, and the <a href="qtdoublepropertymanager.html#rangeChanged">rangeChanged</a>() signal which is emitted whenever such a property changes its range of valid values.</p>
