居中调整大小的 Qwizard 页面
Center resized Qwizard page
我有一个 Qwizard
有 2 页。
当向导打开时,它位于屏幕中间。
第一页比第二页小。
单击下一步并显示第二页时,它会将额外的项目添加到第一页的底部,但不会重新居中页面。
在较小的屏幕上,这意味着按钮在屏幕底部不可见,除非用户将 window 向上移动才能看到。
我尝试使用标准的 QT 小部件居中,但 Qwizard
似乎对此没有反应。
如何重新居中向导的第二页以便显示整个小部件?

如果你想使 window 居中,你必须在它可见时进行,在这种情况下,必须使用 currentIdChanged
信号,但是当插槽被调用时,即使是新的 window 不可见,所以我们稍后将使用 QTimer
更新它。
