@JonB Ok, I understand now. I would expect the installation program to warn the user of this incompatibility, but that is so. I'll try the fix in the post you indicated. Many thanks, Jean-Claude

@fcarney C++ has grown to be a very versatile language. It can be used to solve "real world" engineering problem, teach someone to code, enter one of these for fun code contests and much more. That type of code is good for one of these tasks at least :) https://youtu.be/DEqXNfs_HhY

@SGaist Thank you for detailing the subject even after this discussion, and for all the contributions you have made. That will be the approach I'm going with.

I didn't intend this question to be a joke or blaming session. I invested quite some time already in trying to make testing Drag&Drop work. Does anyone have an idea how to (automatically; also in CI) post the necessary events to make the drag-engine recognize them? Nothing I tried inside the Qt-framework worked so far, because the drag-engine circumvents the Qt-framework completely. At least on Windows; could be different on Unixoid systems, but I don't have the liberty to use that system. Just a thought: is there a platform-plugin available for testing on Windows? Currently the default one is loaded.

@AndrzejB Are you looking for QFileSystemModel + QTreeView? See https://doc.qt.io/qt-5/qfilesystemmodel.html#example-usage.

@J-Hilk I guess no

@Yaldiz In what way is it "wrong"? Release builds are smaller than debug builds because they do not contain debug information.

I came to the idea of adding a context property (set initializeEngine) publishing the needed meta data...not ideal yet but good enough for my needs so far...

Figured it out. What I was trying to do was make it so if you selected a top level item in the tree it would select it's first child instead. But I was doing this from the currentItemChanged slot, which apparently doesn't work. So instead I had to use a QTimer::singleShot to call it after the signal was done... void on_treeWidget_currentItemChanged(QTreeWidgetItem *current, QTreeWidgetItem *previous) { if (current->childCount()) { QTimer::singleShot(0, ui->treeWidget, [this, current](){ ui->treeWidget->setCurrentItem(current->child(0)); }); } }

one simple way is to overlay a grid layout of proper resolution densty and then use the placement policies to center and size the buttons in their respective cells.

Hi, You are not using Qt sockets there since you are using ZMQ. You should take a look at this article from ICS implementing an application using ZMQ and Qt.

You're welcome ! Well, yours could become one :-)

Ok. I have got the font type information by font file mime type. Here is my solution. Code: QString getFontType(const QString &fileName) { QString fontType = ""; QMimeDatabase mimeDB; QMimeType mimeType = mimeDB.mimeTypeForFile(fileName, QMimeDatabase::MatchContent); if (mimeType.name().contains("application/x-font-ttf")) { fontType = "TrueType"; } else if (mimeType.name().contains("application/x-font-otf")) { fontType = "OpenType"; } else { fontType = "OtherType"; } return fontType; } So, the issue is resolved.

@SGaist said in half-ordered qmake subdirs for optimal compilation speed?: Hi, You are making a mistake. Qt 4.8 already has support for depends. See the 4.8 SUBDIRS variable documentation. Oops, I misunderstood the wiki saying "Qt 4.8.x does not support it at all ", it seems that applies only to Visual Studio. Thanks!

appreciate your response

@jsulm as i said its stuck on this vPlayer->deleteLater(); and delete vPlayer; and vPlayer->setMedia(QUrl(Url)); and vPlayer->play(); if i do only vPlayer->deleteLater(); its stuck if i do only delete vPlayer; its stuck if i do only vPlayer->setMedia(QUrl(Url)); its stuck if i do only vPlayer->play(); its stuck lets say like that .. i open my app .. i run in my cmd ffmpeg.exe to stream my screen to my rmtp server and now i have link to my stream like that https://example.com:2083/live/stream.flv i call the function LoadStream() and its working i can see the video now i close the cmd with the ffmpeg to stop sharescreen the video is black .. now if ill try to remove or to reload QMediaPlayer its stuck .. lets say i open again the cmd and run ffmpeg and run vPlayer->play(); its stuck if ill try to reload the link vPlayer->setMedia(QUrl(Url)); its stuck .... all this happend only if i close the stream before i remove or stop the QMediaPlayer ..

@SGaist Yes sir, that was the mistake, I used QVBoxLayout(), but the correct is a QFormLayout. Thank you so much.
