qt中设置菜单高度
如题所示,我建立一个菜单,代码如下,但是菜单项的高度太小了, { popupMenu = new QMenu(this); QAction *action1 = new QAction(tr("&New1"), this); QAction *action2 = new QAction(tr("&New2"), this); QAction *action3 = new QAction(tr("&New3"), this); QAction *action4 = new QAction(QIcon("./load.png"), tr("Bookstore"), this); popupMenu->addAction(action1); popupMenu->addAction(action2); popupMenu->addAction(action3); popupMenu->addAction(action4); popupMenu->exec(); } 我用如下的方法设置菜单项的高度,但是都不行: popupMenu->setFixedHeight(300);//这样只把菜单变大了,action还是那么小 popupMenu->setStyleSheet("QMenu::item { min-height: 100px }");//不好用? 究竟如何才好呢? 感谢大家的热心解答,我把我的收获贴在下面: 首先是简单的方法: popupMenu->setStyleSheet("QMenu::item{ padding:100px;}"); 这一句话就够。 其次使用QWidgetAction: 1)首先 class MyMenuItem:public QWidget { Q_OBJECT public: MyMenuItem(QWidget *parent) { new QLabel("test",this); } }; 2)其次: MyMenuItem *item1 = new MyMenuItem(this); item1->setFixedSize(100,100);//这里可以设置大小 QWidgetAction *action1 = new QWidgetAction(popupMenu); action1->setDefaultWidget(item1); MyMenuItem *item2 = new MyMenuItem(this); QWidgetAction *action2 = new QWidgetAction(popupMenu); action2->setDefaultWidget(item2); MyMenuItem *item3 = new MyMenuItem(this); QWidgetAction *action3 = new QWidgetAction(popupMenu); action3->setDefaultWidget(item3);
