General and Desktop

Item delegates only works on item views, in your case, the popup view of the combo box. If you want to change the painting of combo box's current text, then it must be done in paintEvent() of the combo box. If you are talking about the items in the popup view, then I don't understand because they should be elided by default. (If you use your own item view, check QAbstractItemView::textElideMode.)

@SGaist Thank you

@VRonin @JonB Thank you :)

Simply add '-Wno-attributes' to your compiler flags.

Hi Try overwrite https://doc.qt.io/qt-5/qcombobox.html#hidePopup and see if that makes it controllable.

@fcarney I'm using a lot of QElapsedTimer objects into a lot of threads without any problem.

I found the solution... Only on Linux, the static library that will be linked to my shared library MUST be recompiled using -fPIC flag. I don't understand why...but only works in this way....

OK! That will get the job done! Thanks - it's not knowing the idioms that always catches you out.

Hi and welcome to devnet, @JuliusCaesar said in How to properly close QThread: StartPlayFile You call exec in that method and you connect your signal after calling StartPlayFile.

Thanks__

@Pl45m4 Windows 10, Qt Creator 4.13.2 (Community)(Basing on 5.15.1 MSVC 2019), Qt 5.15.1, tried different compilers but usually MSVC 2019 64-bit

@Christian-Ehrlicher said in Subclassing QIODevice: if (port1.setBaudRate(9600)) <<-- here you try access even if open failed I fixed this, but problem stays... Source code from topic header was updated to. [image: image.png] Why did it call QIODevice::isSequential but not my own implementation?

I answered this previously, with an examlple for QFrame as base class here: https://forum.qt.io/topic/96728/change-button-color/3 You should be able to adjust it for QPushButton.

@charry Yes, you are normally supposed to double-click to edit a cell (one click to select the cell, double-click to edit the cell). If you want single-click to edit, you should look at, say, QTableView::setEditTriggers(QAbstractItemView::AllEditTriggers). See if one of those values do what you want? If not, have a read through e.g. https://stackoverflow.com/questions/18831242/qt-start-editing-of-cell-after-one-click, there are other possibilities there. Or further hits via Google qtableview click edit.

@J-Hilk Wow! They think of everything! I wonder if that would accept -fconstexpr-steps fibonacci(25) ;-) OK, enough now, thanks!

@TomNow99 Your explanation isn't really clear. Do you open in QtCreator? What window do you mean? Kit selection? If you want to build for 64bit you need Qt build for 64bit and a compiler for 64bit. So, simply install Qt 64bit version.

@dheerendra , could you please provide your feedback on this issue?

Microsoft Windows 10 10.0.17763 Ok i will post there, thank you!
