General and Desktop

Ok I found what is causing that - the torus is created facing Z. Thanks.

Hi, Not a direct answer but why not use QDesktopService::openUrl ? Or are you trying to make your app open that file type ?

By the way, can you give more information about your setup ? (hardware/software)

@David-Jacobson Hi Well if a widget is not shown http://doc.qt.io/qt-5/qwidget.html#visible-prop returns false, there is really no reason to redraw on screen as its just wasted efforts. ( as doc talks about) I think this is what you are seeing.

@mrjj Yeah! Fantasstic answer!! Thank you very much!:) We close question [EDIT: Expletives removed --JKSH]

So this problem is related with my system? can someone run a QOpenGLWidget with my format in their pc?

Hi and welcome to the forums. You can use the http://doc.qt.io/qt-5/qsqltablemodel.html#details There is sample in the docs of how to hook up the model to the view. There are also other models if showing a table is not what you want. The http://doc.qt.io/qt-5/qsqlquerymodel.html allows to use SQL to select the data. Im not sure what Qtaddon can create regarding UI files. QtCreator can both create a stand alone UI and one that has .h and .cpp also. I assumed its the same with the addon but i have no VS to test it. Does addon offer more than one option for UI file ?

@JKSH Thanks, yes I am aware of this possibility in creator. IIRC I had encouraged you to publish the browser extension for Chrome. Great tool! Basically use it all the time. I have stumbled across a couple of macros without a trace of documentation. Personally I consider as a pity.

@mrjj Thank you very much!

I think I am running qmake. Just did a full Creator update and now I can run the calendar example, so maybe it was a bug that got me and was fixed. Time will tell. Perhaps I somehow changed to make from qmake, unsure, but thank you for the tip. FWIW: I had copied and executed the comment in Makefile at the bottom of the top header section, and after then was when my troubles began. That was for a different project. After executing the qmake config command, I was able to build my project successfully from cmd line using make (will try with qmake, thanks for tip) and also from within Sublime Text 3, which I normally use. The examples started to fail to build in Creator after then. Why (if true) did my configuring another project affect Creator? What is the proper way to configure projects for external building outside of Creator that won't affect Creator's operation, if that is what happened? Any hints or advice on those lines much appreciated. Thanks.

@KiranRudigi is your issue solved? if so please don't forget to mark your post as such. Thanks

@Bart_Vandewoestyne said in QLineEdit in modal QDialog: cannot enter text.: So apparently, somewhere between Qt 4.8.7 and Qt 5.11.3 there is a change in behavior for the QWidget::grabKeyboard() method in combination with modality grabKeyboard is the ultimate "modality" and is very invasive. If you're using it (regularly) it probably means you are doing something you shouldn't be. (or we were doing something wrong and were just lucky in 4.8.7)? It is possible. No way to tell beside boiling it down to an MRE which can be dissected.

No direct way to do this in Qt. You need to write this on your own.

That is the right way.

Ended up figuring this out using Spacers. New Grid code below: QGridLayout* gridLayout = new QGridLayout(); this->setLayout(gridLayout); QTabBar* unitTabs = TabGenerator(QTabBar::RoundedEast); unitTabs->addTab("Unit"); QTabBar* subsystemTabs = TabGenerator(QTabBar::RoundedNorth); subsystemTabs->addTab("Subsystem"); QTabBar* logOrStateTabs = TabGenerator(QTabBar::RoundedWest); logOrStateTabs->addTab("Log"); QStackedWidget* mainView = new QStackedWidget(); QSpacerItem* leftVertSpacer = new QSpacerItem(1,1,QSizePolicy::Minimum, QSizePolicy::Expanding); QSpacerItem* rightVertSpacer = new QSpacerItem(1,1,QSizePolicy::Minimum, QSizePolicy::Expanding); QSpacerItem* topHorizSpacer = new QSpacerItem(1,1,QSizePolicy::Expanding, QSizePolicy::Minimum); gridLayout->addWidget(subsystemTabs, 0, 1); gridLayout->addWidget(logOrStateTabs, 1, 0); gridLayout->addWidget(mainView, 1, 1, 2, 2); gridLayout->addWidget(unitTabs, 1, 3); gridLayout->addItem(leftVertSpacer, 2,0); gridLayout->addItem(topHorizSpacer, 0,2); gridLayout->addItem(rightVertSpacer, 2, 3);

You're welcome ! Qt is C++ so by learning the second you'll be able to master the first :)
