class KIntNumInput |
|
|
An input widget for integer numbers, consisting of a spinbox and a slider. KIntNumInput combines a QSpinBox and optionally a QSlider with a label to make an easy to use control for setting some integer parameter. 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.

Constructs an input control for integer values with base 10 and initial value 0. |
|
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().
value - initial value for the control base - numeric base used for display parent - parent QWidget |
|
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 arbitrary long chain).
below - append KIntNumInput to the KNumInput chain value - initial value for the control base - numeric base used for display parent - parent QWidget Deprecated use the version without the below parameter instead. |

|
|
Returns the maximum value. |
|
Returns the minimum value. |
|
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). Returns the minimum size necessary to show the control |
|
Returns the prefix displayed in front of the value. See also setPrefix() |
|
Returns the current reference point |
|
Returns the curent value in units of the referencePoint. |
|
Emitted whenever valueChanged is. Contains the change relative to the referencePoint. |
|
|
sets focus to the edit widget and marks all text in if mark == true
|
|
|
Sets the maximum value. |
|
Sets the minimum value. |
|
Sets the prefix to prefix. Use QString() to disable this feature. Formatting has to be provided (see above). #setSuffix() |
|
min - minimum value max - maximum value step - step size for the QSlider slider - whether the slider is created or not |
|
Sets the reference point for relativeValue. |
|
Sets the value in units of the referencePoint |
|
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 suffix to suffix. Use QString() to disable this feature. Formatting has to be provided (e.g. a space separator between the prepended value and the suffix's text has to be provided as the first character in the suffix). #setPrefix() |
|
Sets the value of the control. |
|
Returns the string displayed for a special value. See also setSpecialValueText() |
|
Returns the spin box widget. Internal |
|
Returns the suffix displayed behind the value. See also setSuffix() |
|
Returns the current value. |
|
Emitted every time the value changes (by calling setValue() or by user interaction). |
