Detailed Description
KDoubleNumInput combines a QSpinBox and optionally a QSlider with a label to make an easy to use control for setting some float parameter. An input control for real numbers, consisting of a spinbox and a slider.This is especially nice for configuration dialogs, which can have many such combinated controls.
The slider is created only when the user specifies a range for the control using the setRange function with the slider parameter set to "true".
A special feature of KDoubleNumInput, designed specifically for the situation when there are several instances in a column, is that you can specify what portion of the control is taken by the QSpinBox (the remaining portion is used by the slider). This makes it very simple to have all the sliders in a column be the same size.
It uses the KDoubleValidator validator class. KDoubleNumInput enforces the value to be in the given range, but see the class documentation of KDoubleSpinBox for the tricky interrelationship of precision and values. All of what is said there applies here, too.

Sets the special value text. If set, the spin box will display this text instead of the numeric value whenever the current value is equal to minVal(). Typically this is used for indicating that the choice has a special (default) meaning. Definition at line 835 of file knuminput.cpp. References QWidget::layout(). |
