@SGaist thanks for your answer, there is no way to don't list all files in the qrc? I want to do this dynamically. If there is no way, I'll going to try to add a file resource "folder.json" for example who going to list all directory (name + path)

@v-n-lee said in Pyside2 toHtml()？: But I don't know how to transmit the code to python That is because you cannot do so, until QWebEngineCallback is dealt with. Did you understand what I wrote and the Qt bug posts it references?

Did you re-run qmake after modifying your .pro file ? If not then either nuke the build folder and restart a build or force a run of qmake. On a side note, your .pro file has two issues: you have HandleURL.mm in both SOURCES and OBJECTIVE_SOURCES. If you are using a recent version of Qt, you don't need the later. The other issue is the backslash after main.cpp.

Hi, You can share also the combobox selection model.

Note that there is a WIP patch to add cursor shapes to pointer handlers : https://codereview.qt-project.org/c/qt/qtdeclarative/+/286882

Might be a silly question but are you sure that -qws parameter is passed to your QApplication instance ? Depending on what you want to test, you might also want to consider Qt's own QTest framework.

Hi Just as a note. It's also possible to do signal to signal connects. So if MainWindow just needs to know data has changed to reload something then you could also Define new Signal in class A void DataChangedForB and internally when you create the B's, connect B's signal datachanged to A::DataChangedForB signal And then in MainWindow, simply connect Mains slot to the new A::DataChangedForB signal However, if you are using sender() to access the B' instance, this wont work.

Hi and welcome Adding to @SGaist, What is HomeWindow inherited from ? If its just a QWidget, then when you give it a parent it will get inserted into the parent and not act as a window homewindow = new HomeWindow(this<<<< parent , ui->textEdit_2->toPlainText());

@v-n-lee For PySide2 see https://forum.qt.io/topic/110775/pyside2-tohtml/2.

@JonB okey thanks i try

@Pl45m4 The layout should be as attached image - https://ibb.co/M7tN1LG Yes you're correct it should be above the cancel/set. Everything you see is one widget on one mainwindow apart from the tumbler which I cant move into place. I can position eveything in the main window correctly. The tumbler is the quick-widget incorporating QML (quickWidgettum ) which is out of place and is always in the middle of the screen for some reason. So the main window is in a QHBoxLayout I have the tumbler widget in the same QHBoxLayout. Do you mean I need to place the tumbler in a seperate QVBoxlayout?

@SGaist Thanks ... I do call unregisterResource whenever I register another one, but I need to know at the end of the main() function which one is active. So the helper class sounds like a good idea.

Thanks. This was really helpful.

@Yash001 As @Christian-Ehrlicher & I have suggested, maybe you should really be down-sampling to reduce your data points. Having said that, if you are saying that a properly-compiled 64-bit now bombs out in the same way as 32-bit at what we think is only half a gig of so of memory on a machine with plenty of free RAM, something sounds wrong there. You could do some more investigations on the machine, seeing how much you are really allocating and how much free memory you are able to access. I would want to understand that before I figured what I need to save away to file or whatever.

Hi, The idea behind the painter save/restore combo is to keep said painter "clean" i.e. you return it in the same state as you received it. The fact that it seems to work the same way without it just means that there's no change that influence the next painting step. You could be using a dynamic chain of helper functions that modifies the painter, if you modify the transformation matrix in one of them and do not restore the painter before the next function, then this one will not paint the way you expect it.

Hi, Yes that book is still relevant. Qt 6 is not here yet. Beside that, one of the goal of Qt 6 is to be a "boring update" meaning that you should have minimal work to do (if any) on your code base to move to it and you also have the Qt 5.15 lifetime to clean things up.

@ahsan737 said in How to ensure complete string is received over bluetooth?: @SGaist correct me if I am wrongly using UTF8. Currently, I am receiving data from Arduino being sent via Bluetooth with serial mode (8-n-1). Well, I am guessing you are also responsible for the code running on the Arduino but by first guess is that you are likely receiving ASCII rather than UTF8. You should check.

Can you explain exactly how you are doing currently to build your application for your target ?

@Stevendragoes Hi Yes as the UI hold the widgets you put in visually and the other one seems like a dangling pointer which will crash.

@mrdebug thank you so much. for the sake of clarification, I do not need to define baud rate, parity, start/stop bits in Qt?

Did you define the brightnessChanged() in c++ or qml file ? From which component it is coming ?

@MajidKamali said in Ribbon-like QToolButton group: This is what I want actually :) There is no such a widget, but putting 4 QToolButtons into a layout shouldn't be that hard...

Yesterday i faced the same issue. The only thing i did is that i downloaded "Java SE Development Kit 8 - jdk1.8.0_241" then both the errors regarding the Platform SDK and SDK manager worked properly.

Hi @PyGrrl_FL, Glad you solved it. So please mark this topic SOLVED too. Thanks!

Hello @rrlopez, I'm somewhat familiar with RidgeRun products from your dev pages. This does indeed seem like what I am trying to implement in our product. We use both Caffe and TensorFlow engines with TensorRT, with pre/post processing implemented in C++/CUDA. Adopting Gstreamer is something that I'm highly interested in, as well as ease of integration with QML. My main question would be: what are the advantages over the DeepStream framework? In the context NVIDIA Tegra platforms only, we're not planning to target others for now. I must admit that NVIDIA sample code is frequently a mess and support is not the most reliable.

There is no built-in way to change cursor, but you can use quick-private module and override MouseArea. Add QT += quick-private to your *.pro file. Create CustomMouseArea class: #include <QPixmap> #include <QCursor> #include <QtQuick/private/qquickmousearea_p.h> class CustomMouseArea : public QQuickMouseArea { Q_OBJECT public: explicit CustomMouseArea(QQuickItem* parent = nullptr) : QQuickMouseArea(parent) {} public slots: void setBitmapCursor(const QString& path) { QPixmap p(path); QCursor c(p); setCursor(c); } }; Register it as QML type in main.cpp before qml file loaded to engine: qmlRegisterType<CustomMouseArea>("Test", 1, 0, "CustomMouseArea"); Use in in QML: ... import Test 1.0 ... CustomMouseArea { anchors.fill: parent Component.onCompleted: setBitmapCursor(":/images/cur1.png") } This is just a simple examle, better way to use Q_PROPERTY.

I will be happy to provide a "minimal example" of what I do. However, be forewarned that this could be at best a skeleton of what is going on. Since setTabOrder is so commonly used, it seems that giving me a non-trivial example of what works would be a quicker way to my solution. That way the onus is on me, and not someone else, to understand the example. For the barest skeleton, typedef QList<QWidget*> tEditor; typedef QList<type1*> tEditorList; typedef QList<QStringList> inventory; for (int i=0 ; i<inventory.count() ; i++) { tEditor* = new tEditor; tEditor->setup(inventory.at(i)); tEditorList.push_back(tEditor); } idxmax = tEditorList.at(0).count()-1; sort(&inventory); for (int i=1 ; i<inventory.count() ; i++) { QWidget* last = inventory.at(i-1).at(idxmax); QWidget* next = inventory.at(i) .at(0); setTabOrder(last, next); }

Here is my solution: I have created a new app from the template of Qt Creator and compared it with the example project for Qt Android: I conclude, that I have to modify the .pro file. First of all I had to add the following line: ANDROID_PACKAGE_SOURCE_DIR = $$PWD/android-sources Then I had to replace DISTFILES, that is automatically added by Qt Creator, if I create a Java class: OTHER_FILES += \ main.qml \ android-sources/src/com/hello/android/Backend.java \ android-sources/AndroidManifest.xml Finally I had to edit the AndroidManifest.xml, that I have copied from the exmaple project, in the text editor mode: <activity android:configChanges="orientation|uiMode|screenLayout|screenSize|smallestScreenSize|locale|fontScale|keyboard|keyboardHidden|navigation" android:name="com.hello.android.Backend" android:label="Hello Android" android:screenOrientation="unspecified"> The last step was not necessary in the project of my initial question.

Found it. Thanks to all now everything is fine.

Create a QDir and call absolutePath()

@Chris-Kawa Thx a lot. Issue closed.

@diredko What is the answer? This thread is incomplete, 4 years old or not.

@JKSH Okay, finally I did it. I wasnt able to compile any of this tools (cqtdeployer, deployqt) with my standard qt installation (5.5) in Linux Mint 19.2/32. Maybe there is only needed one preference or any other - it's too hard for me as a beginner. BUT I analyzed the output of cqtdeployer (a structure of folders with the needed libraries and finally a shell-script) and I could adopt it for another simple application. And for some of the qt-examples, all worked - I only added 3 more .SO (all for 64 bit). THEN I made a similar structure for 32bit and collected the needed .SO So far it worked. I seen my applications on Mint 17, 18, 19, Ubuntu Mate (64bit) and on Mint 18, 19 and Debian (32bit). So its prove enough for me it works. I packed all with 7zip so it becomes in fact a portable application to can run anywhere. AND for me as a Windows-User it's logical solution and similar to that what many applications do there: bring along their own runtimes (.SO) Probably there are 1000 more efficient and clever solutions to deploy - but nobody even told me any one working. And my Linux dont let me copy even my own files... forbidden, forbidden, forbidden.... :-)

Thanks for the input guys, much appreciated!

Nachtrag: Habe jetzt eine Lösung auch für Linux gefunden. War nur noch 3x komplizierter und nerviger als bei Windows. Generell würde ich mir wünschen, daß solche Aufgaben auch in eine IDE eingebunden werden. Daß man sagen könnte, das soll mein Zielsystem sein oder meine Zielsysteme und dann baut der Pakete. Sonst hört irgendwie die Unterstützung nach dem Compilieren der Anwendung schlagartig auf. Nicht alle haben ein Qt auf dem Rechner - die meisten inclusive mir haben sicher noch nie vorher davon gehört, daher sollte man doch auch ein Interesse daran haben, denen eine einfache Installation zu geben. Vorausgesetzt, man hat ein Interesse, daß irgendeiner das eigene Progi nutzt :-)

Je vous remercie, j'ai ajouter les libs ssl nécessaires et cela fonctionne correctement.
