Detailed Description
KIntNumInput combines a QSpinBox and optionally a QSlider with a label to make an easy to use control for setting some integer parameter. An input widget for integer 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 KIntNumInput, designed specifically for the situation when there are several KIntNumInputs 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 KIntValidator validator class. KIntNumInput enforces the value to be in the given range, and can display it in any base between 2 and 36.

Constructor & Destructor Documentation

Constructs an input control for integer values with base 10 and initial value 0.
Definition at line 271 of file knuminput.cpp. |
|
Constructor It constructs a QSpinBox that allows the input of integer numbers in the range of -INT_MAX to +INT_MAX. To set a descriptive label, use setLabel(). To enforce the value being in a range and optionally to attach a slider to it, use setRange().

Constructor. the difference to the one above 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 arbitary long chain).

Sets the special value text. If set, the SpinBox 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.

Sets the text and alignment of the main description label.

This method returns the minimum size necessary to display the control. The minimum size is enough to show all the labels in the current font (font change may invalidate the return value).
