Drop application shortcut into qt application (Windows)
To drop an application shortcut into a Qt application on Windows, you can utilize the QDropEvent
and handle the event in the appropriate widget. Here's an example of how you can achieve this:
- Create a custom widget that will handle the drop event. For example, let's call it
DropWidget
:
cpp#include <QtWidgets>
class DropWidget : public QWidget
{
public:
DropWidget(QWidget* parent = nullptr) : QWidget(parent)
{
setAcceptDrops(true);
}
protected:
void dragEnterEvent(QDragEnterEvent* event) override
{
if (event->mimeData()->hasUrls())
{
event->acceptProposedAction();
}
}
void dropEvent(QDropEvent* event) override
{
if (event->mimeData()->hasUrls())
{
QList<QUrl> urls = event->mimeData()->urls();
QString filePath = urls.first().toLocalFile();
// Process the dropped file (e.g., open it or extract information)
qDebug() << "Dropped file path:" << filePath;
}
}
};
- In your main application, create an instance of the
DropWidget
and set it as the central widget of the main window:
cppint main(int argc, char* argv[])
{
QApplication app(argc, argv);
QMainWindow mainWindow;
DropWidget dropWidget(&mainWindow);
mainWindow.setCentralWidget(&dropWidget);
mainWindow.show();
return app.exec();
}
The DropWidget
class overrides the dragEnterEvent
and dropEvent
functions to handle the drag-and-drop events. In the dropEvent
function, you can access the dropped file(s) by extracting the file path from the QDropEvent
object.
When a file is dropped onto the DropWidget
, the file path will be printed to the console. You can modify the dropEvent
function to perform any desired actions with the dropped file, such as opening it or processing its contents.
Remember to include the necessary headers (#include <QtWidgets>
and any additional headers specific to your application) and link against the required Qt libraries.
With this implementation, you should be able to drop an application shortcut or any other file onto the Qt application and handle it accordingly.
