3.7 WFileDropWidget - how to cancel uploads
Added by Mark Petryk 10 months ago
Hi,
How can I simply cancel and then remove all dropped files;
In the code below (line 2535 and beyond), I want to throw away all the uploads and clear out the upload widget, and remove everything. How can I 'remove' the files from the uploads() vector? This code doesn't seem to work, and the uploaded files persist in the vector.
Looking at the source code, the 'remove()' function seems to trigger on the current index, and since the current index is zero at this point, nothing gets actually removed.
2501 void
2502 WEB::FolderTableView::
2503 handleDrop( std::vector< Wt::WFileDropWidget::File *> _files )
2504 {
2505 std::cout << __FILE__ << ":" << __LINE__ << " " << __FUNCTION__
2506 << " index:" << fileDropWidget()-> currentIndex()
2507 << " size:" << fileDropWidget()-> uploads().size()
2508 << std::endl;
2509
2510 /*
2511 ** If the uploads are allowed, then do the upload
2512 ** dialog thing.
2513 **
2514 */
2515 if( m_pbUpload-> isEnabled() )
2516 {
2517 if( m_fileDropDialog )
2518 delete m_fileDropDialog;
2519
2520 /*
2521 ** Open pop-up dialog to allow the user to see what is
2522 ** uploading and its statuses and everything and all that.
2523 **
2524 */
2525 m_fileDropDialog = new FileDropDialog( rootFolder(), currentFolder(), m_fileDropWidget );
2526 }
2527
2528 /*
2529 ** Uploads are not allowed in this area, so just throw everything
2530 ** away.
2531 **
2532 */
2533 else
2534 {
2535 for( auto file : _files )
2536 {
2537 std::cout << __FILE__ << ":" << __LINE__ << " cancel:" << file-> clientFileName() << std::endl;
2538
2539 fileDropWidget()-> cancelUpload ( file );
2540 }
2541
2542 std::cout << __FILE__ << ":" << __LINE__
2543 << " all canceled:" << fileDropWidget()-> uploads().size()
2544 << std::endl;
2545
2546 for( auto file : _files )
2547 {
2548 std::cout << __FILE__ << ":" << __LINE__ << " remove:" << file-> clientFileName() << std::endl;
2549
2550 fileDropWidget()-> remove ( file );
2551 }
2552
2553
2554 /*
2555 ** the uploads() should be empty, no?
2556 **
2557 */
2558 std::cout << __FILE__ << ":" << __LINE__
2559 << " all canceled:" << fileDropWidget()-> uploads().size()
2560 << std::endl;
2561
2562 Wt::WMessageBox::show("Drop File Upload", Wt::WString::tr( "fileDropUpload.wrongFolder" ), Wt::Ok );
2563 }

Hello Mark,
I apologize for the very late response, it has been very busy lately.
It indeed is the case that remove()
uses the current index as a cutoff, with the logic being that only uploaded files can be removed, and the current index should always correctly reflect the number of uploaded files.
So for some reason this doesn't appear to be the case.
Are you uploading files one by one, or uploading a couple at once? I'd like to be able to reproduce this problem.
Best,
Matthias
