How to show full text of QComboBox without resizing



  • Hello All,
    I've a QcomboBox which should display the full text of current item when mouse is hovered on it. This should happen without resizing the QComboBox.
    The solution that i can think of is to have a QLabel which can show rich text on QCombobox when mouse is hovered on it. I tried tooltips and they weren't visually appealing, so i thought of using QLabel.
    But how can i do this, i mean how can i capture mouse hover event and display QLabel exactly on top of QcomboBox?
    I'm new to GUI programmig & to Qt. Please share your ideas.

    Hi and welcome to devnet,

    Are you looking for something like QToolTip ?

    Hi,
    I tried tool tip but it din't look that good visually,
    So i want to have something which can show rich text & QLabel is what i thought of using.
    Btw does tooltip allow text fromating & changing background colors & stuff like that.
    But still tooltip is for small text & some of my items are dynamically changing which can be of large length at times.

    Yes you can use rich text in tool tip, there's a link in the detailed description of the class for that.

    How big can your items be ?



  • thanks for the quick replies @SGaist & i'll check that link in class detailed description now,
    Well, some items of combo boxes have several object names so i can't guess how big that item is gonna be. I just want the user to be able to see all those object names when they hover mouse on QComboBox.
    This is the reason i want to use something else like QLabel but i donno how to show exactly on top of combobox and this should work cross platform too.



  • Well, I'm happy with QToolTip. That means that i'll have a tool tip which displays full text of combobox currently selected item which changes with the current item.
    Thanks to @SGaist .
