QDial 功能
|
||||
旋钮控件提供了刻度、是否环绕等功能
|
||||
|
||||
.setWrapping(on: bool) 设置是否开启环绕,即不在下方留有缺口,而最大值最小值位置紧贴
|
||||
.wrapping() -> bool 获取是否开启了环绕
|
||||
.setNotchesVisible(visible: bool) 设置刻度是否可见
|
||||
.notchesVisible() -> bool 获取刻度是否可见
|
||||
.setNotchTarget(target: float) 设置刻度间的间距,单位为像素,默认值3.7
|
||||
.notchTarget() -> float 获取刻度间距
|
||||
.notchSize() -> int 获取当前刻度尺寸
