使用两个按钮和一个Label封装了一个功能和状态圆角组合按钮,Label用来显示颜色或者图片。
实现的效果如下:
显示图片:
显示红色:
其中颜色或者图片是通过函数设置进去的。
两个按钮:前一个是状态按钮,可以Check,表示使用此项功能;后一个按钮是功能按钮,可以Check,表示跳转到此功能对应的选项。两个按钮都有信号,可以通过信号进行连接你需要的槽函数。
具体实现代码:
#include <QPushButton> #include <QLabel> class QStateFunctionButton : public QWidget { Q_OBJECT public: QStateFunctionButton(QWidget *parent = 0); ~QStateFunctionButton(); void setColor(const QColor &color); void setImage(const QImage &image); void setText(const QString &text); signals: void stateButtonClicked(bool bClicked); void functionButtonClicked(bool bClicked); private: QPushButton *m_stateButton;//状态按钮 QPushButton *m_functionButton;//功能按钮 QLabel *m_colorImageLabel;//显示图片或者颜色 };
#include "QStateFunctionButton.h" #include <QHBoxLayout> #include <QPainter> QStateFunctionButton::QStateFunctionButton(QWidget *parent) : QWidget(parent) { m_stateButton = new QPushButton(this); m_functionButton = new QPushButton(this); m_colorImageLabel = new QLabel(this); m_stateButton->setCheckable(true); m_stateButton->setSizePolicy(QSizePolicy::Preferred, QSizePolicy::Preferred); m_stateButton->setStyleSheet("QPushButton{border:2px groove gray; border-top-left-radius:16px;border-bottom-left-radius:16px;border-style: outset;}" "QPushButton:checked{background-color:rgb(85, 170, 255);}"); m_functionButton->setCheckable(true); m_functionButton->setSizePolicy(QSizePolicy::Preferred, QSizePolicy::Preferred); m_functionButton->setStyleSheet("QPushButton{border:2px groove gray; border-top-right-radius:16px;border-bottom-right-radius:16px;border-style: outset;}" "QPushButton:checked{background-color:rgb(85, 170, 255);}"); m_colorImageLabel->setScaledContents(true); m_colorImageLabel->setFrameShadow(QFrame::Sunken); m_colorImageLabel->setFrameShape(QFrame::Shape::Panel); QHBoxLayout *pHBox = new QHBoxLayout(this); pHBox->setSpacing(0); pHBox->setContentsMargins(0, 0, 0, 0); pHBox->addWidget(m_stateButton, 1); pHBox->addWidget(m_functionButton, 3); pHBox->addWidget(m_colorImageLabel, 1); connect(m_stateButton, &QPushButton::clicked, this, &QStateFunctionButton::stateButtonClicked); connect(m_functionButton, &QPushButton::clicked, this, &QStateFunctionButton::functionButtonClicked); setColor(QColor(0, 0, 0, 255)); } QStateFunctionButton::~QStateFunctionButton() { } void QStateFunctionButton::setColor(const QColor &color) { m_colorImageLabel->setAutoFillBackground(true); QPalette pal = m_colorImageLabel->palette(); pal.setColor(QPalette::Background, color); m_colorImageLabel->setPalette(pal); } void QStateFunctionButton::setImage(const QImage &image) { QPixmap pixmap = QPixmap::fromImage(image).scaled(m_colorImageLabel->width(), m_colorImageLabel->height(), Qt::IgnoreAspectRatio, Qt::SmoothTransformation); m_colorImageLabel->setPixmap(pixmap); } void QStateFunctionButton::setText(const QString &text) { m_functionButton->setText(text); }
