@JonB Yes ! and my problem is solved thank you @posktomten

@CJha So it's obviously internal. Ignore it, and no you won't be able to alter what qApp->topLevelWidgets() returns, just remove any QComboBoxPrivateContainers.

The problem arises from the usage of the method m_model.setStringList(). The latter always clear the previous data, hence the index always reset upon its call. Solution: Use m_model.setStringList() only in the constructor to init the model. After that manually insert the row on the model and set the data for the respective row. This can be achieved with a simple modification in the slot method. MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent) , ui(new Ui::MainWindow) { ui->setupUi(this); m_model.setStringList({"1","2"}); ui->comboBox->setModel(&model); } void MainWindow::on_pushButton_clicked() { m_model.insertRow(model.rowCount()); m_model.setData(model.index(model.rowCount()-1), "3"); } In the example above, "3" is appended to the list model without changing the current index from the QComboBox.

@Proton-Phoenix Thank you!

@mrjj said in QComboBox foregroun color not displayed in main widget: Hi That sets the colors when drawn. It sounds like you want to also change the selection color ? https://forum.qt.io/topic/108718/change-qcombobox-popup-highlighted-item-background-color/12 So in a "human" test it works, if I set it, it works properly. But when I try to load my settings and set it "programmatically", even tho it says it sets pallets (btw I had to use ButtonText). Then it does not work... sigh. Its bananas. Will try to make simple examples.

@artwaw I'm not sure, but in addition to @SGaist you may also find you want to use https://doc.qt.io/qt-5/qabstractitemview.html#openPersistentEditor ?

@Pl45m4 I'll try this...changing it's position

@SGaist Thanks I got it working, I don't know why it works but I'll take it. I updated the first post for future reference.

@learnist Np :) However, for a real app, you should also consider the use case where users spell the new name wrong and want to delete it/edit it later to correct it.

@mikael-larsson Hi You could try an event filter on the Combobox and call the code for hover effect but if your effect is purely stylesheet based then i think you then must send it fake hover event to trigger it or something like that. You might also be able to subclass the combo and rig the paintEvent with if (someflag) option.state |= QStyle::State_MouseOver; to trigger hover on command from the event filter/ or combo hover or how you plan to trigger it.

I think I have found a solution that is not necessarily complete (e.g. drive the combbox with keyboard). I add a boolean (e.g. mSkipToogle=false) at the same place than mSkipHide. I rewrite eventFilter (QObject* object, QEvent* event). bool CFilterCountryComboBox::eventFilter (QObject* object, QEvent* event) { QEvent::Type type = event->type (); if (object == view ()->viewport ()) { switch (type) { case QEvent::MouseButtonRelease : case QEvent::MouseButtonPress : mSkipHide = true; mSkipToogle = false; break; case QEvent::Hide : case QEvent::Show : mSkipToogle = true; break; default : break; } } if (type == QEvent::MouseButtonRelease && static_cast<QMouseEvent*>(event)->button () == Qt::RightButton) { return true; } return QComboBox::eventFilter (object, event); } Now rewrite toggleItemCheckState (int index) void CFilterCountryComboBox::toggleItemCheckState (int index) { if (!mSkipToogle) { QVariant value = itemData (index, Qt::CheckStateRole); Qt::CheckState state = static_cast<Qt::CheckState>(value.toInt ()); setItemData (index, (state == Qt::Unchecked ? Qt::Checked : Qt::Unchecked), Qt::CheckStateRole); } else { mSkipToogle = false; } } It seems to work on Windows with Qt 5.12.7. Good luck

@hobbyProgrammer You cannot have a combo which is both bound to a model and has some extra row inserted into it --- it's one or the other. There are several possible approaches: Make your SQL query return a UNION ALL which includes a literal <select> as an extra row. Not really nice, because it makes the <select> be an extra row from the query. Copy the result set from the query into another model (you probably only need a list, perhaps a QStringList) where you insert the extra <select> as an item and use that as the combo's model. If you don't get a better example, this is the most obvious to code. Interpose a QIdentityProxyModel between the query model and the combo, and add the extra row there. I suspect this is the way it's supposed to be done(?).

That article answers quite a few questions I had about that scenario, woah nice thanks! But... I kinda like the idea of more "control"... somehow, creating the widget this way allow the user to resize it which won't be possible using a popup, so I would like to get the focus to work properly... TIA

@SGaist Awesome thanks! I think I can get it to do my bad biding now :- )

@AloyseTech IIRC hidePop() will reset the Popupwidget, so maybe hijack the add/remove process. Call hidePopup before adding are removing item and call showPopup afterwards?

What's the problem replacing the QSpinBox with a QComboBox in the example? Did you even try?

@J.Hilk ok then you can follow the suggestion from @mrjj (in case you would have set a custom model you would have need to handle the Qt::SizeHintRole in your data() method) or try to set a QStyledItemDelegate to the view and use your stylesheet.

I did this: ui->comboBox->clear(); ((QSqlTableModel*)ui->comboBox->model())->select(); And it's working!

@koahnig Not directly. You have to fake it: bool eventFilter(QObject* watched, QEvent* event) { if( watched == comboBox ) // or watched->inherits("QComboBox") ?? { // you may want to do additional checks here for a generic solution (like the combobox is really editable, it has a insert policy set, etc) switch( event->type() ) { case QEvent::FocusOut: { QKeyEvent keyEvent( QEvent::KeyPress, Qt::Key_Enter, Qt::NoModifier ); QCoreApplication::instance()->sendEvent( watched, &keyEvent ); } break; } } return BaseClass::eventFilter(watched,event); }

Hi @SolaVitae , as suggested by @jsulm you have to delete param name in connect signal, you can keep const & Your connect will be then: connect(charactersBox, SIGNAL(currentIndexChanged(const QString &)), this, SLOT(characterSelectedChange(const QString &)));

Right, that's the best solution if you are using a QTabWidget.

I had create a model with key and value and pass it to qml, it worked!!! Sorry for late reply. Thank you @raven-worx

@tamlong0205 I think most of this can be done from C++ side. You can add a function in the model which can return what type is the data for current index. This function will be called from QML and depending upon its value use a Loader to load the specific delegate. Perhaps setting currentIndex in Component.onCompleted handler ? Create a C++ function which will store in info in the model itself i.e When you change the index in ComboBox call this function and update the value there and may be maintain a role to store this update.

I apologise for the delay in response. The question was to make sure that the combobox always pops up in a given direction or position.

Ok, thanks a lot! Marked as solved!

QComboBox {background-color:rgb(190,190,190);color:black;padding-left: 10px;padding-right: 30px;border-style: solid;border-width: 0px;} "padding-left: 10px;" the padding will shift the combo-box displayed content form the left edge QComboBox::drop-down {subcontrol-origin: padding; subcontrol-position: top right;width: 40px;border: 0px ;} "subcontrol-position: top right;" and the above will position wot text to the right. Hopefully this helps.

@VRonin With the provided code the whole dropdown list will be invisible. Do you know how to keep the items unaffected?

@mrjj said: this->ui->personComboBox then pointer must be corrupt?

@raven-worx Thanks a lot ! This does exactly what I want !

@SGaist Thanks. That's definitely another option. I suppose these approaches are as good as it gets for having a toolbar item auto-adjust to horizontal vs. vertical. Thanks again.

@Rondog I was already thinking of setting the maximum width for each combobox but when creating the comboboxes I dont know the width of the scrollareas viewport. @SGaist Will try that, seems to be the more nice solution :) Thanks

Solution that works for me is to call unpolish and polish on combo box: auto cb = new QComboBox(this); cb->setItemDelegate( new QStyledItemDelegate); style()->unpolish(cb); style()->polish(cb);

@_compiler said: thanks.

@elveatles Thank you. You were right.

Hi, Isn't QComboBox::activated what you are looking for ?
