General and Desktop

@Kent-Dorfman In Qt 5.12.4 is openssl 1.1.1 included. Do you know, how I use this version or compile the libs?

Hi Well its a bit odd as normally the options is just not there is not right classes/types so since it allows it, one should think it should work. Give it some hours and see if someone has an idea. I know writing a small sample is a bit hard as its a plugin. Im trying to find some other Designer button i could try with and see if it generally do not work or there could be something in the plugins XML or similar that needs filling out.

@Grand-Williamson and how this issue is related to Qt framework?

@Patrick-Fromberg said in Qmake TEMPLATE variable manipulation via command line interface: Why is TEMPLATE += or TEMPLATE-= not a syntax error then? Those are operators on list variables. Most probably because nobody bothered to make it into an error. What effect can any variable change have after processing is complete? After parsing sounds better? I guess that is what they have meant. The documentation of the cli option -tp explains that this will add a prefix to the TEMPLATE variable. The documentation of the TEMPLATE variable does not say anything about a prefix. What would prefix.lib as TEMPLATE value mean? Just like the other option, will this be "after processing"? This is used on Windows to generate Visual Studio stuff, I think. More info https://stackoverflow.com/questions/1043294/qt-qmake-tp-vc-to-create-visual-studio-project-files Will qmake command line options applied to a subdirs project also recurse to the child projects? Yes, as far as I remember. Just try it out ;-)

OK, thank you for the answer

I found the solution: https://doc.qt.io/qt-5/stylesheet-customizing.html#box-model The bug in the current code was that that we tried to use margins instead of borders. m_pProgressBar->setStyleSheet(QString::fromUtf8(R"( QProgressBar { border-image: url(:/images/launcher/ProgressBar_BG.png); font-family: "Verdana"; font-size: 13px; font-weight: bold; color: #bfbfbf; text-align: center; border-top: 2px; border-left: 2px; border-bottom: 3px; border-right: 3px; } QProgressBar::chunk { border-image: url(:/images/launcher/ProgressBar.png); } )")); Setting the borders correct in the Style and not using margins in the ```Style::chunk```` solved the problem.

Thanks to all ... I have decided to remain with QDialog because it has so many convenient signals and slots. In the constructor, I can resize the window using QScreen, e.g.: // Set the window to fill the available desktop area, // but leave a little space to allow for resizing the dialog: QScreen *screen = QGuiApplication::primaryScreen(); if (screen) { QRect r = screen->availableGeometry(); int l,t,w,h; l = t = 10; w = r.width() - 2*l; h = r.height() - 2*t; this->setGeometry(l,t,w,h); } Also, it was necessary to set the sizePolicy of the dialog to Ignored in order to allow the user to resize it without it jumping back to the default dimensions. So I am now marking this as "Solved".

@sonichy Which version of Deepin? According to Deepin Wiki, F11 should work (as it seems to be the standard key for displaying a fullscreen window). https://wiki.deepin.org/wiki/Deepin_Terminal#Display_Window_in_Fullscreen (Dont know if this is for terminal window only). Deepin (15.X.X) is Debian-based (Desktop Environment even based on Qt), as written here (https://en.wikipedia.org/wiki/Deepin), so it's probably the same as on Debian (F11)..

@Kerndog73 oh means entirely writing a seperate class for this purpose

hi @mrjj said in index out of range: or items.at(x) sorry i said i never do this calls,but in the lib itself there is that call. Just after closing the file writePath() is called: void RenderItemList::writePath(QPainter& painter, bool updatedFromFile) { QPainterPath path; ItemToBase *item = list.at(0); // << crash here item->setParams(scale, windowSize.height(), offsetx, offsety); erros # else RaiseFailFastException(nullptr, nullptr, 0); # endif qt_message_fatal(QtFatalMsg, context, message); { Q_ASSERT_X(i >= 0 && i < p.size(), "QList<T>::at", "index out of range"); i saw ind debug mod that list was empty .. i initialised it after reading the file, now everything works correctly. thank you for help

@Kent-Dorfman Yep, running on ARM. BTW, could you tell me how to make a LineEdit's text cursor always is visible. I found something in source code , if (QApplication::keypadNavigationEnabled()) { if (e->type() == QEvent::EnterEditFocus) { end(false); d->setCursorVisible(true); d->control->setCursorBlinkPeriod(QApplication::cursorFlashTime()); } else if (e->type() == QEvent::LeaveEditFocus) { d->setCursorVisible(false); d->control->setCursorBlinkPeriod(0); if (d->control->hasAcceptableInput() || d->control->fixup()) emit editingFinished(); } } it's in QLineEdit's event(), so how can I use this setCursorVisible(bool) ?

Bingo!!!

@mrjj thanks.

Subclassed QGestureRecognizer and created own custom solution. It's little bit ugly, but working. Waiting for bug fix.

@jsulm ok thank you for the answer. Let me check. once again thanks

@pablomuniz Can you show your code? Maybe something can be optimised, but without the code is impossible to say.

You can wrap it in your own thing that happily converts to and from a connection and make the bool operator always return true: class MyConnection { public: MyConnection(const QMetaObject::Connection& c) : conn(c) {} MyConnection& operator=(QMetaObject::Connection& c) { conn = c; return *this; } operator QMetaObject::Connection() const { return conn; } operator bool() const { return true; } private: QMetaObject::Connection conn; }; If it's just for testing then you could typedef it, something like: #ifdef TESTING using ConnType = MyConnection; #else using ConnType = QMetaObject::Connection; #endif and use it like this: ConnType conn = connect(...); Q_ASSERT(conn); // always true in testing, can fail otherwise but I kinda agree with @VRonin that it makes little sense.
