General and Desktop

Did you check that all the dependencies of it are also deployed/available ?

@SGaist said in QUndoStack with dropdown: You would need to implement your own model to set on the QComboBox. @vijaychsk Given what @SGaist is pointing it out here, you would have to write some code to replicate the functionality. Using your button to icon to "pop up" a QUndoView in some shape or form sounds like less work than utilising a QComboBox. You might want to bear that in mind.

I do not own such a board. You should contact the company that builds them.

@Christian-Ehrlicher Ok Thank you for the clarification

If anyone finds this same problem, what solved it for me was to add "harfbuzz" to the list of dependencies, now everything is working just fine!

I fixed it with: setStyleSheet("QHeaderView::section{ padding-left: 4px; padding-top: 1; padding-bottom: 1; }");

@jsulm said in Action Button in MenuBar: setCurrentIndex Thanks a lot I tried the setCurrentIndex method and it worked! like magic.

@JKSH said in QByteArray to quint16: There are not enough bytes, so you will get a QDataStream::ReadPastEnd For Qt 5.7 or later: quint16 var; stream.startTransaction(); stream >> var; if(!stream.commitTransaction()){ quint8 tempVar; stream.startTransaction(); stream >> tempVar; if(!stream.commitTransaction()){ //handle this error } var=tempVar; }

@AlexKrammer Just a small point. @eyllanesc uses a member variable for mMovie. You use a local variable for QMovie *movie = new QMovie(...). Be aware that this means you leak a QMovie. If your on_btn_ON_clicked() can be called more than once you have no way of releasing the previously-created movie (unless whatever your GifEffect *effect is does that for you). And the same leak applies to your GifEffect *effect = new GifEffect();, unless your ui->frm_BG->setGraphicsEffect(effect) looks after that too. Your on_btn_OFF_clicked() sets that to Q_NULLPTR, does that release any current GifEffect and its QMovie?

@Dannick-Stark One correction to what I wrote before (thanks @JonB for the hint): if you use "sh -c" then on Linux you have to pass everything after -c as ONE string!

@SPlatten It's a widget, so simply add it to your window like any other widget and add it to the layout, so it consumes whole space. Then put all other widgets inside the frame.

@jsulm @raven-worx Hi! Thanks for your reply! I want to start my qt application in startup after login in qt application then I will press the button behind which my wireshark application will drive. Wireshark support command line arguments. Thanks

Thank you both very much for replying! I will implement an extra check, then. Thanks!

Hi, Does it also happen from a clean build ?

@JonB Yes, I followed @artwaw example and worked perfect. Thank you for helping me too !
