@skylendar

you shortened the log, so I can't see the GDB version. Please check these.

Also, GDB must be python enabled, and last the python dumper script must be loaded. Have you checked the directories?

Regards

Thank you so much for your helping

@aha_1980 : I just noticed something else: In the log file, there are lines saying "GDB 71101", presumably because it is using v7.11.1 (?!). But I have installed GDB v8.2 in both usr/bin and usr/local/bin. And I've set those locations in QtCreator's options pages for kits and for debuggers. There should be no way for QtCreator to find an older GDB version.

The GDB version in both usr/ folders above is 8.2, confirmed by running via terminal. And I did not find any older stray 7.11.1 versions that QtCreator could be picking up.

Another oddity. Is there any other options page where the GDB location needs to be set?

@im_vidhya - Look at the QScreen class. There are functions to give you the available screen size, for example.

But if you do the layout correctly, as Christian pointed out, then the user can resize the windows just about any way they want without problems. Qt layouts take care of the rest. I only use the information from QScreen to show my main windows in a reasonable initial default size, centered on the screen.

Figured out my issue. I just needed to instantiate a QQmlDebuggingEnabler object. Calling QtQml.QQmlDebuggingEnabler() before instantiating my QApplication was enough.

@jsulm we make an installation file for our combined system, including multiple programs sharing some but not other resources. we use an nsi script to manage this. usually works fine. I just missed updating some of the .dll files.

@Ratzz
Thanks for your references.

@J.Hilk
It works ! THANKS :-)

@jsulm
I got this, thanks

My bad, I misread from where the signal came from.

@sergsmi privet !
вы можете использовать QML Shape type : https://doc.qt.io/qt-5.11/qml-qtquick-shapes-shape.html

@Devopia53
It works! , Thanks.

@MikhailG thank u so much sir
i will try.

Sorry for the late response!

If I use NMake Makefiles, I get the following Error:

-1: error: Failed to activate protocol version: "CMAKE_GENERATOR" is set but incompatible with configured generator value.

I changed to the MSVC 2017 toolchain and configured it the following way:

and I'm getting the same error as above.

thanks !! . I will look into both of them

It is boost library issue. Looks like you are not using the capture method of boost properly . Look at some examples of boost and fix your issue.

@Paul-Colby Thanks

i myself did something like this :)

QVariantMap json_map; const QJsonDocument doc = QJsonDocument::fromJson(output); qDebug().noquote() << doc; qDebug().noquote() << doc.array(); foreach (auto value, doc.array()) { qDebug().noquote() << value; qDebug().noquote() << value.toObject(); qDebug().noquote() << value.toObject().value("name"); json_map["name"] = value.toObject().value("name").toString(); json_map["installed"] = value.toObject().value("installed").toBool(); json_map["id"] = value.toObject().value("id").toString(); json_map["filename"] = value.toObject().value("filename").toString(); }

@noone Would this be of any help to you? https://forum.qt.io/topic/79730/no-build-step-for-android

It seems this guy had the same problem and solved it with adding gradle.

Usually that error has to do with missing ndk/sdk or the more likely ant/gradle. Try running the build or deploy on the command line and see if it gives you more information.

SOLUTION

with the help of @mrjj i found solution. It's just that instructions were not clear on tutorial

Steps

get the Qt creator source : git clone --recursive https://code.qt.io/qt-creator/qt-creator.git

set qmake version . your qmake version should be close to the qt version you are using . for e.g. if you are building for 5.10 your qmake should also use 5.10.

you can set qmake version by

sudo mv /usr/lib/x86_64-linux-gnu/qt-default/qtchooser/default.conf /usr/lib/x86_64-linux-gnu/qt-default/qtchooser/default.conf_orig sudo vim /usr/share/qtchooser/my_Qt_5.10.0_Desktop_gcc_x64.conf <Qt_dir>/5.10.0/gcc_64/bin <Qt_dir>/5.10.0/gcc_64/lib ln -s /usr/share/qtchooser/my_Qt_5.10.0_Destop_gcc_x64.conf /usr/lib/x86_64-linux-gnu/qt-default/qtchooser/default.conf

check qmake by qmake --version

mkdir qt-creator-build
cd qt-creator-build
qmake ../qt-creator/qtcreator.pro

4. ``` cd qt-creator-build make qmake_all make -j <number-of-cpu-cores+1>

wait for some time . it will take long time to build.

now you have both source and build of Qt creator . Now just follow the wizard and point the qt soruce and build locations

build and run

voila !! \0/

@mranger90 said in sqlite commands not working in qt:

Apparently you can not directly access an SQLite database from a resource. There are some discussions about this, but I cant find the links right now.

Indeed, Qt resources are compiled into the executable (or standalone binary file) which is read-only. Good catch! :-)

@jsulm said in Qt creator cannot successfully start app built with custom built qt bundle on windows:

@farta clone means here cloning from Qt repository (git clone)

Thank you.
I never clone it from Qt repository.

There is no straightforward API for this. I see several possibilities:

custom painting in QQuickPaintedItem custom painting in QQuickItem custom painting via GL shaders custom painting in QML Canvas a set of 4 animated Rectangle components, simulating the line. An ugly solution, but probably the easiest to do

Perhaps BorderImage component can be forced to do an animation like that, but I doubt it.

@nour.m

if you mean here:
http://freetexthost.com/l5wzgtntzb
than no, you did not make the changes @aha_1980 told you to do

SOURCES += main.cpp mainwindow.cpp my_polyhedron.cpp myqglwidget.cpp HEADERS += mainwindow.h My_CGAL_Config.h My_Face_base.h My_Halfedge_base.h my_polyhedron.h My_Vertex_base.h myqglwidget.h

still mising \ at the end of the line

also you are adding the widgets module twice. I'm not sure in what that will result, but you should remove one

QT += core gui QT += widgets //remove me DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x000000 greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

@SGaist, could You provide an example please - fixed mylibrary.pro? Thanks!

Don't @ the moderators unless you have an issue requiring moderation.

Depending on the content of your line edit, you can use toLatin1() or toUtf8() rather than making these two conversions.

@dokif Do you see the plug-in in QtCreator under "Help/About Plugins..."?

@hassene
Hi and welcome
Is there a reason you simply dont use a layout ?
To make it autofollow the size of window ?
if you place a QLabel on a form ( mainwindow.ui) , right click somewhere on
empty form, and select Layout menu and select layout, the label will follow maniform.
https://doc.qt.io/qt-5.10/examples-layouts.html

@aha_1980
Hi. As I know, qtcreator doesn't handle well with auto keyword. I wish another trick, when I put cursor onto a auto variable's call, such as

auto v = SomeClass(); v.func();

Cursor is at func(). I wish to use shortcut key to show the option list, just as the result that I move cursor to Locator and input

:m func

then it will give me a list where func appears.

Is there such a shortcut ? If it exists, it may improve my code-reading greatly

@GregWilsonLindberg
I think that the g++ version is what is doing it. The old version of rasbian
is using g++ v4.9.2. The new version of rasbian is using g++ v6.3.0-18+.
For the old compiler we had had to add an "INCLUDEPATH =
/usr/include" line into the .pro file to get everything picked up
properly. For the new compiler (and the change from #include to #include_next
in cstdlib) that messes up.
I'm removing the INCLUDEPATH, (which seems to have been included as -isystem
instead of -I) and that is fixing the problem.

@jsulm yes, I tried launching it this way but it didn't resolve the issue - the error is same. Thanks for suggestion though :)

@JonB I think i won't be able to understand something more detailled and that answer the whole questions =)

Thanks a lot, you ma real expert ! ;D

For future reference, this approach only works if you know in advance all the roles you will use.
You can use KSelectionProxyModel instead if you need a proper general implementation

This is strange. could you try if this snippet works for you?

#include <QApplication> #include <QWidget> #include <QVBoxLayout> #include <QPushButton> #include <QTableWidget> #include <QLabel> int main(int argc, char *argv[]) { QApplication a(argc, argv); QWidget mainWid; QStringList changedValues; QVBoxLayout* mainLay=new QVBoxLayout(&mainWid); QTableWidget* tableWidget = new QTableWidget(&mainWid); QPushButton* button = new QPushButton(QStringLiteral("Display list"),&mainWid); QLabel* resultLabel = new QLabel(&mainWid); mainLay->addWidget(tableWidget); mainLay->addWidget(button ); mainLay->addWidget(resultLabel ); tableWidget->setColumnCount(1); tableWidget->setRowCount(5); for(int i=0;i<5;i++){ QTableWidgetItem* const newItem= new QTableWidgetItem; newItem->setData(Qt::EditRole,i); tableWidget->setItem(i,0,newItem); } QObject::connect(tableWidget,&QTableWidget::cellChanged,[&changedValues,tableWidget](int row, int column)->void{changedValues<<tableWidget->item(row,column)->text();}); QObject::connect(button ,&QPushButton::clicked,[&changedValues,resultLabel ]()->void{resultLabel->setText(changedValues.join(','));}); mainWid.show(); return a.exec(); }

Did you have any system update happening in between ?

@gizalp said in When resizes the entire window, the vertical layout (and thus its content) will stretch to fit it:

How can I enable these options?

click on the background. You probably also want to use "lay out in a grid" instead

Then even easier to use 1 QSqlQueryModel or QSqlTableModel
