QPushButton：如何使它足够小以仅显示它的文本

Question

我有这些按钮，我试图减小它们的尺寸，但它们拒绝变小。它们都在QHBoxLayout中。 我可以缩小它们只显示+， - ，＆lt; - ＆gt;和欧共体文本？

在布局上：

->setSpacing(1);
->setContentsMargins(1,1,1,1);
->setAlignment(Qt::AlignLeft);

在按钮上：

->setSizePolicy(QSizePolicy::Minimum, QSizePolicy::Minimum);

将按钮添加到布局时：

->addWidget(button, 0, Qt::AlignLeft); 

Answer 1

You can get your buttons a little smaller by removing the padding on the buttons using style sheets.

ui->myPushButton->setStyleSheet( "padding: 0px;" );

I would however strongly advise against using incredibly small buttons. As per Fitt's Law, the smaller a button is, the longer it takes for the User to move their cursor to within the bounds of the button, and the more likely they'll miss and click a neighboring element (made even more likely as there's no padding between the buttons in your example). This leads to user frustration, which is never a good thing.
