Hi, Aren't you re-inventing QWizard ?

@J-Hilk ok It gives me the same result

Hi, AFAIK, that's the goal yes. The deletion happens after the finished emit signal is emitted.

@lfreeman6490 So start debugging that function! I take it you actually have a test_function in the test_program, else what do you expect. Maybe you need the different code in https://sites.northwestern.edu/yihanzhang/2019/08/22/how-to-invoke-python-function-from-c/, I don't know?

@ChrisW67 Thanks for your answer, as you said change '/' to '\' and in that case if it worked, I generate the backup correctly, the only thing that left me with doubts was with the password, so what I did was remove the password to the postgres user, and with that fix my problem. thanks anyway for your reply.

@mrjj Here is what I have done with paintEvent(), mouseMoveEvent(), mousePressEvent() and mouseReleaseEvent(), that's what I mean by "dot": https://imgur.com/a/cF5EeTW Now, using QGraphicsItem, I have subclassed it to Dot which has a square as Dot::boudingRect() and is painted as a 2px ellipse (a dot). Should I use my "dot" as a grid, and detect hover, press, and drags when the user is drawing a table, then constrain the user to this "grid" of Dot then add QGraphicsRectItem as the tables, OR maybe stick to paintEvent() to draw (exactly as I did on the video) and only use the Graphic View Framework for the tables ?

Solution found. Might be not so elegant but it works for me. Example published. The video of how it works for mobile here. It's not from model directly, but all of procedures with DB is in different thread. Thx to all. Issue closed.

@JKSH Thank you. I had hoped that there was a simpler way I didn't know about, maybe twerk some configure options and it'll enable and build xcb... But if there's not there's not, I'll just cross compile xcb as you and Christ both suggested.

@SGaist thanks, so what is a normal way to set a dock widget's default width? As I know, there's a method that we can install a event filter on the dockwidget's client widget, and set the widget max and min width in its show event. this method works fine. However, it seems almost every post recommend that we use sizehint() on the dockwidget's client widget. my test result is: it doesn't works fine in my special case. may I know what is your suggestion to implement that?

I want to create in .qs file

@mrjj said in How to pass the parameters between the SIGNAL and SLOTS: so its a logical bug with mence and we cannot not spot it as we see only pieces and its easy to stare blind on own code so you dont either. @ mrjj, @J.Hilk, thank you for your help, so i will try to change my logic of coded, and i will take you know of the evolution

@stretchthebits Yeah, I know, on KDE and xfce you just need to initiate dialog with a parent widget to make it modal. As for other programs - I tried Telegram, which uses Qt as well, and it doesn't have this problem. Tried looking into their code, but couldn't find anything specific, I guess the answer here is to use later versions of Qt

@wrosecrans Yes, I'm rendering using a QOffscreenSurface on a separate thread then displaying the frame on a QWindow on the GUI thread, but it makes sense to have all of the video rendering on the same thread so we're not interfering with the GUI thread. I've successfully tested this concept with GLFW-based OpenGL windows and QT UI. I doubt Vulkan will be any different since from what I understand the render window will still need to sit on the GUI thread.

Hi QPainter can draw an arc so that could be used for it. https://doc.qt.io/qt-5/qpainter.html#drawArc The center image could be an image you draw. i think that would be the most easy. You could also look at this https://github.com/mofr/QtProgressCircle

@J-Hilk , thank you, modified to: QRect rctGeom(rect()); #if defined(TRUTH_DEV) if ( mblnVisibleCopy == true && mrctDev.isEmpty == true ) { //Save current size Size szCurrent(size()), szNew; //Adjust maxmum size to prevent geometry being rejected szNew.setWidth(szCurrent.width() * 2); szNew.setHeight(szCurrent.height()); //Adjust widget geometry allowing for the development area qDebug() << "BEFORE: " << rctGeom; resize(szNew); rctGeom = geometry(); qDebug() << "AFTER: " << rctGeom; mrctDev = rctGeom; mrctDev.adjust(szCurrent.width(), + 40, szCurrent.width(), -40); qDebug() << "rctGeom: " << rctGeom << ", mrctDev: " << mrctDev; } #endif Results: BEFORE: QRect(0,0 208x644) AFTER: QRect(897,32 416x644) rctGeom: QRect(897,32 416x644), mrctDev: QRect(1105,72 416x564) Thank you!

my compiler is mingw32bit and mongocxx driver build in 64 bit . so thats make problem , i solved it by installing 64bit Qt.

The fault module is displayed as qt5gui.dll

@eyllanesc said in QWebView freezes: QWebengineView That works. It's a bit slower (on a Raspberry pi) but it's working fine so far. Thanks.
