@eyllanesc [image: 031bcaf4-f4d8-4c76-8775-25281823cfbc.png] printer->setPageMargins(3, 3, 3, 3, QPrinter::Millimeter); What's wrong with the margin that doesn't apply to the preview?

@JKSH Thanks, I will try this. I m new to QT so finding it difficult. You are right need to organize SVG file as per requirement.

@ChrisW67 Indeed the fasted way is just to try and see. I did not have access to the environment to try it when I posted my last question, so I figured I'd ask about identifying existence of driver beforehand just in case QSerialPort doesn't work when I do try. But luckily it worked. I did learn a lot and have much to learn, thanks for all the help.

@kameshbhai32 Thank you.

The goal is to have the hover style applied correctly regardless of how the widget wound up under the mouse. One example for how the widgets get moved is the window being maximized then restored. If the window is restored and the widget is moved under the mouse as a result of the restore, the hover style isn't applied. The HoverLeave event has the inverse of the issue, where if the widget is moved away it doesn't receive a HoverLeave event. This is mostly an issue with my custom title bar, where if I maximize then restore the TitleBar, the maximize button never receives a HoverLeave event and so displays the hover style when the window is restored and the maximize button is shown. Edit: The HoverEnter seems to function correctly when the window is restored, but the HoverLeave event still has the issue. A better example for the HoverEnter event may be a dynamic layout, where a widget is removed resulting in a different widget moving under the mouse.

@jsulm oh, you're right. So maybe the real reason was I had to take back ownership of the widget every time the tab was closed, so it wouldn't get destroyed. Have been writing this app ever since I started learning programming an year ago, and I can't remember all of my decisions, sorry.

Hi, Depending on what you want to do, you might want to check the nzmqt project which provide integration with Qt. But before trying that, you should rather define your architecture first.

thanks. i will go for karchive then.. greetings

@ADR_PT you may want to start using QSerialPort the asynchronous (non-blocking) approach, by using signals & slots. Take a look at the serial terminal example

Just add the qrc to the list of sources: add_library(Mylib STATIC map.cpp map.h window.cpp window.h resources.qrc ) Since you set AUTORCC ON everything will be done automatically

Sure, but I can't just call super().whatever to draw the rest because that the draws the image itself as well..

@JPatrick You were close, for a noob you did well on your own, you should see some of the questions we get! :) Like I said, do yourself a favour and stick to that new style connect() syntax, then you get compile-time incompatibility error messages, look at those closely and you should be able to discern the cause.

@Krulle said in Struggle with struct, const QVector and register to QML: Can anyone explain? You get the error because QObject's are not copyable. When you use a pointer nothing gets copied since its... a pointer.

@JoeCFD Thanks for the reply. I understand now. I'll try it soon. Thank you for your kindness and clear explanation. (^_^)

Thanks guys! it worked

I solved it,, thank you all. lst_m.append(m) if (pstrList.size() == 0) { pstrList.insert(0, lst_m); } else if (!pstrList.contains(lst_m) ) { pstrList.replace(0, lst_m); }

@eyllanesc Works like a Charme! Thanks Mate!! :D
