C++ QSpinBox::setFocusPolicy方法代码示例

/*! 
 * Makes a labeled spin box, with the label given by [text] to the left of the
 * box and right aligned to it, provided that [layout] is a horizontal layout 
 * box in which to place them.  (In a toolbar, [layout] can be NULL.)  
 * [minValue], [maxValue], and [step] are the  minimum, maximum, and step 
 * sizes for the spin box.  If [nDecimal] is non-zero, it creates and returns 
 * a QDoubleSpinBox with that number of decimal places.  It skips the label
 * if [text] is NULL.  The focus policy is set to ClickFocus.  Keyboard 
 * tracking is turned off.  If a pointer is supplied in the optional argument [labelPtr]
 * (which is NULL by default), it is returned with the label pointer.
