资源内容介绍

在QT中创建一个图片开关控件。该控件允许用户切换显示不同状态的图像，类似于开关的功能。

#include "imageswitch.h"#include <QPainter>ImageSwitch::ImageSwitch(QWidget *parent) : QWidget(parent){ isChecked = false; buttonStyle = ButtonStyle_2; imgOffFile = ":/image/imageswitch/btncheckoff2.png"; imgOnFile = ":/image/imageswitch/btncheckon2.png"; imgFile = imgOffFile;}void ImageSwitch::mousePressEvent(QMouseEvent *){ imgFile = isChecked ? imgOffFile : imgOnFile; isChecked = !isChecked; Q_EMIT checkedChanged(isChecked); this->update();}void ImageSwitch::paintEvent(QPaintEvent *){ QPainter painter(this); painter.setRenderHints(QPainter::SmoothPixmapTransform); QImage img(imgFile); img = img.scaled(this->size(), Qt::KeepAspectRatio, Qt::SmoothTransformation); //按照比例自动居中绘制 int pixX = rect().center().x() - img.width() / 2; int pixY = rect().center().y() - img.height() / 2; QPoint point(pixX, pixY); painter.drawImage(point, img);}QSize ImageSwitch::sizeHint() const{ return QSize(87, 28);}QSize ImageSwitch::minimumSizeHint() const{ return QSize(87, 28);}bool ImageSwitch::getChecked() const{ return isChecked;}void ImageSwitch::setChecked(bool isChecked){ if (this->isChecked != isChecked) { this->isChecked = isChecked; imgFile = isChecked ? imgOnFile : imgOffFile; this->update(); }}ImageSwitch::ButtonStyle ImageSwitch::getButtonStyle() const{ return this->buttonStyle;}void ImageSwitch::setButtonStyle(const ImageSwitch::ButtonStyle &buttonStyle){ if (this->buttonStyle != buttonStyle) { this->buttonStyle = buttonStyle; if (buttonStyle == ButtonStyle_1) { imgOffFile = ":/image/imageswitch/btncheckoff1.png"; imgOnFile = ":/image/imageswitch/btncheckon1.png"; this->resize(87, 28); } else if (buttonStyle == ButtonStyle_2) { imgOffFile = ":/image/imageswitch/btncheckoff2.png"; imgOnFile = ":/image/imageswitch/btncheckon2.png"; this->resize(87, 28); } else if (buttonStyle == ButtonStyle_3) { imgOffFile = ":/image/imageswitch/btncheckoff3.png"; imgOnFile = ":/image/imageswitch/btncheckon3.png"; this->resize(96, 38); } imgFile = isChecked ? imgOnFile : imgOffFile; setChecked(isChecked); this->update(); updateGeometry(); }}
