@DiZhu if you read the docu, you may realize that the collides funcs of QGraphicsItem use bounding boxes of items to detect collision and this may not fit your app. If you have only triangles, it might be relatively easy for you to implement more accurate methods for collision detection. But it can be tough to handle all shapes of polygons.

Thank you for your help.I consider that the point is that executing .sh should be in Component when status of installer is Succcess.

@PatG thanks, This helped me

@JonB Thank you i application is normally running Pictures (⁠◠⁠‿⁠◕⁠) . [image: fed506fc-8f36-40bf-8c4a-cf3c0dcd324f.png]

Hi sorry, I was in the midst of rewriting the code to a simpler example, but decided to try adding Q_INVOKABLE in front of the function that was not working in the .h file. Now it works! Thanks.

opening the qhc file with assitant rather the the .qch file makes a huge difference!!!

@Pl45m4 said in How to dynamically hide/show widgets in a custom QWidget-based toolbar on window resize?: OP asked how caculate the visibility of toolbar items, not the toolbar itself. The toolbar should always be visible, if I understood correctly. I misunderstood earlier — I thought he was showing or hiding the whole toolbar. If the toolbar is a toplevel widget or its parent is the MainWindow, then yes, it still makes sense to handle it the way I mentioned. From MainWindow::resizeEvent(), he should pass the size information to the toolbar so it can decide which items to show or hide based on the available space.

Yes, by default Qt builds dlopens OpenSSL.

Congratulations! Glad to hear you got it resolved. I noticed that QtHttp uses socket->waitForBytesWritten(-1); when writing chunks — it’s a simple and straightforward approach. I’m still curious why QHttp doesn’t apply the same method.

After a long brainstorming till the brain explosion I have decided to use the QTcpSocket object implementing the http request by hand like this QTcpSocket TcpSocket; TcpSocket.connectToHost(Url.host(), Url.port()); if (TcpSocket.waitForConnected()) { TcpSocket.write(QString("GET "+ Url.path()+ " HTTP/1.1\r\n").toLatin1()); TcpSocket.write(QString("Host "+ Url.host()+ " \r\n").toLatin1()); TcpSocket.write(QString("Connection: close\r\n\r\n").toLatin1()); if (TcpSocket.waitForBytesWritten()) { while (TcpSocket.waitForReadyRead()) { ... Seems to work

That makes sense, thank you.

@Pixelord said in Making the VSProject and Binary executable named differently: I looked into the pro file, and tried to change the TARGET name to change the exe project name. It worked, but issue is, it also change the name of the binary output. The project name in QMake is set by the name of the *.pro file. Unlike CMake where everything is named CMakeLists.txt and within that file there is the option for a project(....) command. And as you've already said, the TARGET is for your platform-independent binary output. e.g. foo.pro by default results in a foo project with a foo.exe/foo.dll/foo.so etc. binary. If you want to rename the project you are working on, rename foo.pro to like helloworld.pro and then set separate name(s) for your target(s).

@mirro I already answered: @JonB said in How to kill yourself in qt program?: @mirro Why not tell us whether in that case your SERVICE_CONTROL_STOP code is actually hit, or would you like us to guess? Do you not think we need to know whether your function is being hit? Just pasting more code and not telling us what does/does not happen is not helpful when asking a question. Also this now a Windows programming question, nothing to do with Qt.

@SimonSchroeder I need to get my glasses fixed ! I missed the ; while reading 😅

Thankyou @Pl45m4 for the detail link.

It works! [image: d3b628f8-c13d-49ac-8474-d9b8af794be4.png]

@Alexey-Serebryakov thank you

In Qt3, QVBox is a widget, not a QVBoxLayout. You have two options to handle this: Recreate QVBox by subclassing QWidget. Inside it, use a QVBoxLayout to arrange the child items. Make LCDRange inherit from QWidget, add the slider into a QVBoxLayout inside it, and adjust the layout to match the original logic. Hope this helps you!
