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.

Constructor. the difference here is the "below" parameter. It tells this instance that it is visually put below some other KNumInput widget. Note that these two KNumInput's need not to have the same parent widget or be in the same layout group. The effect is that it'll adjust it's layout in correspondence with the layout of the other KNumInput's (you can build an arbitrary long chain).

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 865 of file knuminput.cpp. References QWidget::layout(). |

Sets the text and alignment of the main description label.

This is an overloaded member function, provided for convenience. It essentially behaves like the above function. Contains the value in units of referencePoint.

You need to overwrite this method and implement your layout calculations there. See KIntNumInput::doLayout and KDoubleNumInput::doLayout implementation for details. Implements KNumInput. Definition at line 720 of file knuminput.cpp. References QSize::width(). |
