thank you sir for your help

Hi, It's possible with dynamic properties, but as you want to pass an object, it's a little bit tricky: In the designer, you create a property named "argument" ( + sign on the right panel) and set groupBox_4 as value for this property. Then by code you can retreave that object: QString name=ui->listWidget->property("argument").toString(); QGroupBox* box=findChild<QGroupBox*>(name); if(box) { // do what you want width the groupbox } From inside LoggerList, you have to start the search from the window : QGroupBox* box=window()->findChild<QGroupBox*>(name);

Thank you it's worked, it seems that my other Frames didn't contain anything so that's why the StackWidgets covered all the window.. Thank you @Pl45m4

Hi On the bright side, when you do declare forward signals, you are doing it just right as accessing widgets left and right produces hard to maintain code that breaks easily. So by being "forced" to surface the external needed data via signals, you define an interface that will hold, even if you refactor the internal widgets. The rest of the app will remain unaffected. \o/

Hi, and welcome! @Akash-Shanmugaraj said in Application Output not Visible in Qt Design Studio: I accidentally clicked some button which disabled the Application Output (for designing app) completely. Your Application Output pane is right there in the middle of your screenshot. It's the other panes that have been hidden. You can bring them back by clicking View > Views > Form Editor, for example.

Thank you for the answer. Setting a child did enable the layout selection. I don't understand the logic behind that at all but ok. QcmEntryGuess are QWidget I've created on the side. They're only a QLabel nested in two layout Althought my QGridLayout is still only consisted of one row. I'm probably missunderstanding one of its property

Achei o problema,. acidentalmente dupliquei a linha QApplication a(argc, argv);

@Dariusz said in QtCreator - some basics questions...: maybe how to change initial type of file from QWidget to QDialog/etc/etc? If you mean how to change the .h, cpp and UI file to be other type ? You will have to change in 3 places .h class MainWindow : public QMainWindow <<< change here .cpp MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent) <<<< change here to new type .ui This you have to do outside creator, and its best if you close it. Open the ui file in other editor. ( its text)

Maybe a dependency is missing so the dll can not be loaded -> use Dependency Walker to see what dependencies you're missing.

@qt_emp I found it I think. When I turned off auto indent it stopped doing this.

@anp405, my first guess would be that by setting PYTHONPATH you are losing the location of PyQt5 package. This depends on your Python and environment setup, but if there is some PYTHONPATH existing, you are overriding it completely instead of complementing. You can verify this by opening a new command line session, setting PYTHONPATH to wherever your code sets it, then running Python interpreter and trying to import PyQt5. Another guess would be that your child process uses different Python environment (e.g. built-in system Python 2), which does not have PyQt5 installed in its site-packages.

@DSpider great! please don't forget to mark your post as solved. Thanks.

I fixed the issue by dropping the source string from the .metainfo files. For anyone that cares I was following these instructions: http://doc.qt.io/qtcreator/creator-qml-modules-with-plugins.html and on step 5 I picked a random metainfo file when I searched the Qt folder for .metainfo, not the one they specifically chose (qtcharts.metainfo vs qtquickcontrols2.metainfo) The qtcharts one was probably for some other type of module use where specifying the source does something I don't need, the qtquickcontrols2 ended up having the syntax I really wanted in the end. Eventually I found this example and found out dropping the source worked: https://forum.qt.io/topic/56207/how-to-load-custom-qml-controls-into-the-qml-designer

@Valveware said in Promoting to custom widget in QtDesigner '*.hpp' no such file or directory [cmake]: file(GLOB_RECURSE QT_MOC RELATIVE ${CMAKE_CURRENT_SOURCE_DIR} FOLLOW_SYMLINKS include/dashboard/*.hpp) Ok that looks like it would indeed moc your cameraframe.hpp.. So that's probably not the issue. Can you share the build log from gcc? And also the ui_main_window.h file as well as ui_cameraframe.h?

It might not be the answer but it is a answer. I declare my charts using QML to maintain declarative / visual design. I only control them from C++ with C++ data. I do all the processing of dynamic axis ranges inside that, I do stupidly high frequency updates. I'd recommend, if you very frequently update your line series like I do to use: void QXYSeries::replace(QVector<QPointF> points) (or QList...) and also set your LineSeries to use open GL either from QML or C++ works fine, you do lose some functionality but it saves using canvas (which is slower) if you have lots of points of data, with many fast updates. HTH

IIRC something like: ui.filters.currentTextChanged.connect(proxyModel.setFilterFixedString)

separate QTreeWidget in a QTreeView and a QStandardItemModel. create a QSortFilterProxyModel and set the QStandardItemModel as its suorce model connect currentTextChanged from the combobox to setFilterFixedString of QSortFilterProxyModel

Hi, for an integer input between 0 and 100 set the mask to "009". Thats all.

@Romain-C Well it still confused me sometimes :)

@fortyff said in Undefined referance to class::function: There are the same errors occured in the "esimplelabel.cpp" file, but I didn't write down here, since it'll consume too much place. Make sure you have all virtual functions that are declared defined. While a declaration of a regular function without a definition is perfectly valid (until it's called), that's not true for virtual methods.

Hi, Which exact version of Windows are you using ? Patch/Update applied ?

@SGaist I just want 1 window with the forms changing for the login and presentation windows. And then ill use dialog windows after the presentation window. Anyways thank you. Ill try QStackedWidget.

Reimplement the resizeEvent of your main widget and resize your label in there.

and it works ! Thank you all :)

Ok, thanks.

@curiosport this is cpp files so you need cpp compiler. Then you would open the qiron.pro and compile it all. It would produce some DLLS in the plugin folder. Those should be copied to the plugin folder in QtCreator. Note: the source is for older Qt 4.6 so it might have compile errors u need to fix if using newer Qt.

@havasu78 said in QWebEngineView in QtDesigner: but QWidget is not an item that can be added to the form in PyQt5Designer Why do you think so? QWidget is located under "Containers" in the Designer.

I also have QTableWidgets inside tabs of a QTabWidget and have had this problem for a long time. Every time the .ui file is saved in QtCreator it sets the horizontal headers of all my tables to invisible except for the first table.

@Wieland Ah. thank you. Ok, you are right - spacer wont do it. He could set Alignment to right. (for edit) Then they stay same with all the time. Not sure its 100% the wanted effect? https://www.dropbox.com/s/px3t6ir6d767nn7/keepright.zip?dl=0

Thank you, I will. For the time being I am gonna move the label text into source code. Cheers for you help!

tl;dr It's QFrame adding this extra pixel. set frameShape to NoFrame

Hola @Heinserberg said: ... jugando con los layout logre bastante lo que quería , nose si de la manera correcta pero al cambiar el tamaño de la ventana los botones se mantienen a la derecha ... Bueno, si hace lo que buscabas, en principio ya está. Lo único que quizás pueda hacerse con menos layouts, pero eso es algo que irás viendo a medida que diseñes más ventanas y vayas entendiendo su funcionamiento. Para esto no hay más que practicar, personalmente cuando me inicié con Qt, me costó mucho el tema de los layuot, pero ahora, después de haber diseñado muchas ventanas, las hago mucho más rápido, aunque de vez en cuando me encuentro con alguna que me cuesta diseñar XD Un saludo

You're welcome ! Good to know :) Since we know now that it's working, please update the thread title prepending [solved] so other forum users may know a solution has been found :)

Hi @White_Rabbit, and welcome to the Qt Dev Net! I don't know if there's a way to change the display format of the editor. You can ask the Qt Creator engineers directly (and request the feature to set the editor's format) at the Qt Creator Mailing List: http://lists.qt-project.org/mailman/listinfo/qt-creator . Subscribe to the list and post there.
