总结： （1）setLayout()是设置界面布局，如界面有几行几列 如jf.setLayout(new GridLayout(2,1));//容器共有2行1列。...设置布局GridLayout——容器几行几列 JFrame jf = new JFrame（）； jf.setLayout(new GridLayout(2,1));//2行1列 setLayout()...GridLayout(); // 定义一个GridLayout对象 gridLayout.numColumns = 6; // 设定GridLayout对象的列数 shell.setLayout
创建好一个布局：mainLayout，然后不停地把各个控件往mainLayout里面放，最后调用setLayout(mainLayout)就行了。...会出现这种提示： QWidget::setLayout: Attempting to set QLayout "" on MainWindow "", which already has a layout...You must first delete the existing layout manager (returned by layout()) before you can call setLayout...If layout is the layout manager on a different widget, setLayout() will reparent the layout and make...(layout); // w.setCentralWidget(&window); delete w.layout(); w.setLayout(layout); return
JFrame窗体的默认布局管理器是边界布局管理器，在使用之前应该先使用setLayout(null)取消该布局管理器。 Hello！大家好，我是灰小猿！ ?...了解了这个时候，我使用了setLayout(null)来取消窗体的默认布局管理器，也就是告知窗体不再使用边界布局管理器。...但是意外又来了，在我添加了setLayout(null)之后，发现界面仍然没有变化，如下所示， ? 这就很奇怪了，明明已经取消了边界布局管理器，为什么在设置了控件之后还是没有效果？ ?...经过仔细研究发现，是显示窗体可见的代码setVisible(true);放在了取消布局管理器代码的前面，这就造成了窗体先显示出来，然后才取消了边界布局，这样导致了setLayout(null)就没有了意义...最后将setLayout(null)放在了显示窗体可见的代码setVisible(true)之前，问题解决，结果如下： ?

这种情况下就是两次调用了QWidget的setLayout方法。解决办法是优化代码或者删掉其中一个QLayout。 （2）隐式的设置了QLayout后，再次给QWidget设置QLayout。...mainLayout->addWidget(mFootageList); QWidget* centralWidget = new QWidget(this); centralWidget->setLayout...而后面3处代码又再次显式调用了setLayout()方法，相当于重复设置了。于是出现了上面的警告。解决办法是，删掉1/2处的this指针或者setLayout调用即可。
