Currently this project use some assets and code from [ShadowPlayer](https://github.com/ShadowPower/ShadowPlayer), which have a very interesting license -- do whatever you want but cannot be used as homework -- obviously it's not a so called *free* license. I *may* do some license housecleaning works by replaceing the assets and code implementation when the code become reasonable, and the final codebase may probably released under MIT license. + +Anyway here is a list of file which is in non-free state (with license: do whatever you want but cannot be used as homework): + + - All png images inside `icons` folder. + - FlacPic.h + - ID3v2Pic.h + - seekableslider.{h,cpp} + +Also there are some source code which I copy-paste from Qt codebase, which released under BSD-3-Clause license by the Qt Company: + + - playlistmodel.{h,cpp} diff --git a/mainwindow.cpp b/mainwindow.cpp index 0d271a7..be5af93 100644 --- a/mainwindow.cpp +++ b/mainwindow.cpp @@ -3,6 +3,9 @@ #include "playlistmodel.h" +#include "ID3v2Pic.h" +#include "FlacPic.h" + #include #include #include @@ -13,6 +16,7 @@ #include #include #include +#include MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent) @@ -124,6 +128,31 @@ void MainWindow::mouseReleaseEvent(QMouseEvent *event) return QMainWindow::mouseReleaseEvent(event); } +void MainWindow::dragEnterEvent(QDragEnterEvent *e) +{ + // TODO: file/format filter? + + e->acceptProposedAction(); +} + +void MainWindow::dropEvent(QDropEvent *e) +{ + QList urls = e->mimeData()->urls(); + if (urls.isEmpty()) { + return; + } + + QString fileName = urls.first().toLocalFile(); + if (fileName.isEmpty()) { + return; + } + + // TODO: file/format filter? + + createPlaylist(urls); + m_mediaPlayer->play(); +} + void MainWindow::loadFile() { QStringList files = QFileDialog::getOpenFileNames(this, @@ -281,10 +310,32 @@ void MainWindow::initConnections() { connect(m_mediaPlayer, &QMediaPlayer::currentMediaChanged, this, [=](const QMediaContent &media) { #if QT_VERSION < QT_VERSION_CHECK(5, 14, 0) - ui->titleLabel->setText(media.canonicalUrl().fileName()); + QUrl fileUrl = media.canonicalUrl(); #else - ui->titleLabel->setText(media.request().url().fileName()); + QUrl fileUrl = media.request().url(); #endif // QT_VERSION < QT_VERSION_CHECK(5, 0, 0) + + ui->titleLabel->setText(fileUrl.fileName()); + if (fileUrl.isLocalFile()) { + using namespace spID3; + using namespace spFLAC; + + QString filePath(fileUrl.toLocalFile()); + + if (filePath.endsWith(".mp3")) { + if (spID3::loadPictureData(filePath.toLocal8Bit().data())) { + QByteArray picData((const char*)spID3::getPictureDataPtr(), spID3::getPictureLength()); + ui->coverLabel->setPixmap(QPixmap::fromImage(QImage::fromData(picData))); + spID3::freePictureData(); + } + } else if (filePath.endsWith(".flac")) { + if (spFLAC::loadPictureData(filePath.toLocal8Bit().data())) { + QByteArray picData((const char*)spFLAC::getPictureDataPtr(), spFLAC::getPictureLength()); + ui->coverLabel->setPixmap(QPixmap::fromImage(QImage::fromData(picData))); + spFLAC::freePictureData(); + } + } + } }); connect(m_mediaPlayer, &QMediaPlayer::positionChanged, this, [=](qint64 pos) { diff --git a/mainwindow.h b/mainwindow.h index 8e7e43d..cfe6b10 100644 --- a/mainwindow.h +++ b/mainwindow.h @@ -29,6 +29,8 @@ protected: void mousePressEvent(QMouseEvent *event) override; void mouseMoveEvent(QMouseEvent *event) override; void mouseReleaseEvent(QMouseEvent *event) override; + void dragEnterEvent(QDragEnterEvent *e) override; + void dropEvent(QDropEvent *e) override; void loadFile(); void centerWindow(); diff --git a/mainwindow.ui b/mainwindow.ui index 4cea614..8bd141a 100644 --- a/mainwindow.ui +++ b/mainwindow.ui @@ -16,6 +16,9 @@ 160 + + true + Pineapple Player @@ -185,6 +188,9 @@ QLabel#coverLabel { AlbumCover + + true +
