@cawell which version of Qt? Unfortunately this has a direct relationship. On version 5.9, everything worked fine everywhere. At 5.12 it was broken and it worked as I mentioned above. I didn't look further

@KOHAK said in subprocess cmd Real-time output: I want to enter CMD command into textbrowser What does this mean? in real time What does this mean? using subprocess module in pyqt. Is there an example site or something like that? If you want to use Python's subprocess then this has nothing to do with Qt, and you should look through any of the plethora of examples of that out on the web, in Python questions/examples.

@sierdzio Ah, okay then. I guess I will wait for the official support. Thanks!

Just changing MenuItem to CheckBox does the job. Menu stays as long as you clicking CheckBox items: Menu { CheckBox { text: "Item A" checkable: true checked: false onCheckedChanged: { console.debug("item A", checked) } } CheckBox { text: "Item B" checkable: true checked: false onCheckedChanged: { console.debug("item B", checked) } } } This topic is still high in search results, so I think it would be helpful to post correct answer. Despite question is old it is still useful.

Hi, IIRC, it's not part of the 6.0 release and should come back between 6.1 and 6.2.

That's true, I definitely can do the interpolation, I'm just avoiding it both because Qt has already done it somewhere in the backend, and because it's going to be messy - as I mentioned I need to draw a vertical line for every pixel's width of the QChart, so it'll be a slope between every point, and then draw up to whatever height it needs. It would be nice to get the smoothness of a spline series as well, but I guess that's just higher order interpolation. I guess what I'm looking for is a way to return a vector of points that describe where, in pixel values, the QChart has drawn the line, but that might be too much to ask. ;) Thanks for your response - I'll probably do the interpolation myself unless someone else knows the magic function call!

Can you update to a more recent build of Qt Creator ? IIRC current is 4.14

Hello @Pablo-J-Rogina , Yes, Ice is properly installed in the VCPKG directory, which is referenced in my generator command ( I accidentally provided the command without the path properly updated in my post above): cmake -G "NMake Makefiles" "-DVCPKG_TARGET_TRIPLET=x64-windows-static-md" "-Dstatic=ON" "-DCMAKE_TOOLCHAIN_FILE=D:\Users\Skewb\Documents\repos\vcpkg\scripts\buildsystems\vcpkg.cmake" "-DIce_HOME=D:\Users\Skewb\Documents\repos\vcpkg\installed\x64-windows-static-md" "-DCMAKE_BUILD_TYPE=Release" .. Since I posted this question I've been studying CMake a bit, and I think the problem is that I can't input options into the generator (I guess?) [image: b4149733-9caf-4d83-a221-00ad94438ea0.png]

@Mourad2021 Now might be on opportune moment to consider moving onto QRegularExpressionValidator instead?

guy,I found that I made a mistake when I created a TCPSERVER and passed this pointer to QTcpServer (which was not needed). This should have caused the newly running socket to exist in the new memory thread, causing an exception on subsequent exits.

@JonB Wait really !? I could swear that they were blocking methods hmmmmmmmmmmmmmmmmmmmmmmmmmmmmm my bad! Thanks :D

I also tried this no luck: networkEditor.setWindowFlags(networkEditor.windowFlags() | QtCore.Qt.X11BypassWindowManagerHint) networkEditor.move(posx, posy) networkEditor.setWindowFlags(networkEditor.windowFlags() & ~QtCore.Qt.X11BypassWindowManagerHint) This topic is relevant: https://forum.qt.io/topic/5375/qt-4-7-0-ubuntu-10-10-cannot-move-application-window-out-of-desktop-bounds/4
