thank you for your help
Qt 5.10.0 added support for native menus on Windows. This caused a regression in Qt Quick Controls 1 ComboBox. ComboBox did not get notified that the menu popup was closed, so it thought it was still pressed and therefore refused to re-open the popup. The bug (QTBUG-64628) has been fixed in Qt 5.10.1. Try updating.

Right now I have a small tool app that runs in the icon tray. When I click on the icon, the app goes into "windowstayontophint" mode. I added a Combo Box on this window. But when I click elsewhere on desktop, and then click the combo box, the drop down window goes to the back of the window. This seems to be a known bug as reported here:
https://bugreports.qt.io/browse/QTBUG-61804
Is there a workaround for this? I am using Qt 5.9.1.
EDIT: Add some code:
This in MainWindow constructor:
Qt::WindowFlags flags = this->windowFlags();
this->setWindowFlags(flags|Qt::WindowStaysOnTopHint);
Then I put a QComboBox in the mainwindow with preloaded items. First time click, the dropdown appears on top as normal. Then I click onn desktop and then back on the mainwindow and combobox. And drop down becomes at the back of mainwindow. CLick on the link above to see what I mean. The bug report also provide screenshot of what is happening.
Nobody want to put an answer, so I answer this myself.
ANSWER: Update to latest Qt.
It did not work for me because I was having trouble updating (noob here). What basically happened was that Selecting "Update" option on Maintenance Tool does not update SDK from 5.9.1 to 5.10.1. It only update certain things like Qt Creator.
I needed to choose "Add or remove Components" and then adding Qt 5.10.1, but only check the MinGW 32bit only. (Uncheck all others otherwise you need them (like android or other)).
Even after that, you also need to manually download CMake (get it from cmake.com) and set it in "Manage Kits" in Qt Creator.
I want to keep focus on TextField. For example i am typing something then tap to button. The focus on TextField is moving to button, that's why keyboard is automatically hiding on Android. I am using Qt 5.9.2. Thanks in advance!
In Qt Quick Controls 2, each control has a focusPolicy property which determines how the control gets focus. The default for controls like Button is Qt.StrongFocus, which means that buttons get focus after being clicked or tabbed into. If you're seeing that a control has focus and you don't want it to, just set its focusPolicy to Qt.NoFocus:
focusPolicy: Qt.NoFocus
i have an app where i have 2 widgets, one widget shows a video and the other one two buttons as transparent widget lying over the video. Means the widget with the buttons has the focus. When now somebody clicks on the video normally this should emit a signal to open a website in an external browser, but while the other widget has the focus, this signal is not emitted while the click only changes the focus to the video but is not getting the click itself.
is there a way to use the click, to change the focus and catch the click event to open my website?

I guess you can try the function: setFocusProxy()
video.setFocusProxy(button);
Maybe you can get some help.
I am working on a small UI with QT Creator and its drag-n'-drop tool (QT Designer). Everything was fine till I realized I had to make some widgets dynamic. For example, I have a checkbox and I want some button to appear only if this checkbox is checked by the user or I would like to change the appearance of another widget when the user clicks on some button.
Is it possible to do it only with QT Designer?
Yes, but it's very limited.
Qt designer have signal&slot editor. Yes, you can connect signal clicked(bool) to setVisible(bool) slot on button and make button visible only when checkbox is checked (see screenshot).
But when You need more complex dynamic interface (e.g. creating buttons), designed will not help You.
I saw once someone making the GUI in QT and he had something I have never seen until now: They looked like big buttons one after another and when you clicked on them, the buttons below were going down, making space for the dialog or tab. It was like, if you click on the button "Draw", suddenly below the button a tab or a dialog or ??? appeared with all the GUI components (radio buttons, listboxes, ...) that you need for draw. When you clicked on another button, this GUI disappeared to make space for another GUI. Does anybody know what it is?
Qt does support tabs.
They are actually different widgets you can switch from in the same window.
Here you can find an example on how to use then: http://qt-project.org/doc/qt-4.8/declarative-ui-components-tabwidget.html
Inside a tab it's just like a normal widget.
