@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.

@enmaniac QWebKit was removed in Qt 5.6. So QWebView is no longer available. Use QWebEngineView as a replacement. In Qt Designer, just add a QWidget to your form and promote it to QWebEngineView (base class: QWidget, header: QWebEngineView). Don't forget to add webenginewidgets to your project file.

@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?

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

... 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.

@Thomas-Hartmann

The problem i see is that QtCreator model is too restrictive...

I just found another problem

I have a plugin, CustomPluginBase
And i develop an app that uses this plugin, linking statically so i can extend some types in cpp, and i register new types under namespace "CustomPluginBase.ExtendedTypes"

Well, QtCreator shows "QML module not found" and as types doesn't exist, even if application works perfectly if i run it. (they get registered)

I imagine that QtCreator overwrite existing qmlRegisterType in code, with no existing plugin, as base plugin exist.

How can i create my signal for text edit with python3 ?
With as many ways i tried, but I did not succeed .. :(

Hi,

Not that I know of. Why would need that ? You can't compile anything that is an abstract

The designer does not pick up the items from a plugin automatically.
But you can write a .metainfo file that defines the contents of the item library.

An example can be found here: https://github.com/qtproject/qt-creator/tree/master/tests/manual/qml/testprojects/plugins.

Just have a look at: MyPlugin.metainfo

Could you provide some more background on your problem?
Are you using QML or Qt Widgets?
Could you share the part of the code that designer is generating from your change?

It is really hard to say anything based on one sentence.
