Detailed Description
Spin box with accelerated shift key stepping and read-only option.The SpinBox class provides a QSpinBox with accelerated stepping using the shift key.
A separate step increment may optionally be specified for use when the shift key is held down. Typically this would be larger than the normal step. Then, when the user clicks the spin buttons, he/she can increment or decrement the value faster by holding the shift key down.
The widget may be set as read-only. This has the same effect as disabling it, except that its appearance is unchanged.

|
Returns true if the widget is read only.
|
|
Sets whether the spin box can be changed by the user.
|
|
Returns whether the spin box value text is selected when its value is stepped.
|
|
Sets whether the spin box value text should be selected when its value is stepped.
|
|
Adds a value to the current value of the spin box.
|
|
Returns the minimum value of the spin box.
|
|
Returns the maximum value of the spin box.
|
|
Sets the minimum value of the spin box.
|
|
Sets the maximum value of the spin box.
|
|
Sets the minimum and maximum values of the spin box.
|
|
Returns the specified value clamped to the range of the spin box.
|
|
Returns the unshifted step increment, i.e. the amount by which the spin box value changes when a spin button is clicked without the shift key being pressed. |
|
Sets the unshifted step increment, i.e. the amount by which the spin box value changes when a spin button is clicked without the shift key being pressed. |
|
Returns the shifted step increment, i.e. the amount by which the spin box value changes when a spin button is clicked while the shift key is pressed. |
|
Sets the shifted step increment, i.e. the amount by which the spin box value changes when a spin button is clicked while the shift key is pressed. |
|
Increments the value of the spin box by the unshifted step increment.
|
|
Decrements the value of the spin box by the unshifted step increment.
|
|
Signal emitted when the spin box's value is stepped (by the shifted or unshifted increment).
|
|
A virtual method called whenever the value of the spin box has changed.
|
|
Returns the initial adjustment to the value for a shift step up or down. The default is to step up or down to the nearest multiple of the shift increment, so the adjustment returned is for stepping up the decrement required to round down to a multiple of the shift increment <= current value, or for stepping down the increment required to round up to a multiple of the shift increment >= current value. This method's caller then adjusts the resultant value if necessary to cater for the widget's minimum/maximum value, and wrapping. This should really be a static method, but it needs to be virtual... |
|
Receives events destined for the spin widget or for the edit field.
|
|
Updates the contents of the embedded QLineEdit to reflect the current value using mapValueToText(). Also enables/disables the up/down push buttons accordingly. |
