|
||
|

.setSizeAdjustPolicy(policy: QAbstractScrollArea.SizeAdjustPolicy) 设置尺寸调整策略
|
||
.sizeAdjustPolicy() -> QAbstractScrollArea.SizeAdjustPolicy 获取尺寸调整策略
|
||
|
||
QAbstractScrollArea.SizeAdjustPolicy枚举值具体有如下三种：

||
https://doc.qt.io/qt-6/qabstractscrollarea.html#SizeAdjustPolicy-enum
|
||
QAbstractScrollArea.AdjustIgnored 滚动区域行为与之前相同，不做任何调整（默认值）
|
||
QAbstractScrollArea.AdjustToContents 滚动区域总是根据视口调整尺寸
|
