Question

qt qss按钮边款颜色设定为什么上面的和下面的边没变色

Answer 1

用enterEvent和leaveEvent头文件：<pre t="code" l="cpp">#include <QPushButton>

class MyButton : public QPushButton
{
Q_OBJECT
public:
MyButton(QWidget *parent = 0);
~MyButton(){return;}
protected:
virtual void enterEvent(QEvent* e);
virtual void leaveEvent(QEvent* e);
};源文件：<pre t="code" l="cpp">
MyButton::MyButton(QWidget* parent)
: QPushButton(parent)
{
setText("I am a button");
setFixedSize(100, 100);
setStyleSheet("QPushButton{background: yellow;}");
}
void MyButton::enterEvent(QEvent* e)
{
setStyleSheet("QPushButton{background: red;}");
}
void MyButton::leaveEvent(QEvent* e)
{
setStyleSheet("QPushButton{background: yellow;}");
}
