Create F1 key in tooltip (similar to qtcreator)

  • Hi,

    I have been searching for the past few days but I cannot figure out on how to do it. I would like to do reproduce a behavior similar to the newest qtcreator where a F1 hint is shown in tooltip and allows you to show full help in a context sensitive manner by pressing F1 while the tooltip is displayed.

    Has anyone tried yet to get the same tooltip feature in their programs?


  • I haven't done it in action but this might give you some hint

    Implement "hoverEvent" on your editor

    Look for the word below the mouse (e.g. QTextCursor::WordUnderCursor is a possible way)

    You should have some "keywords" to check if it points to a specific "help/tooltip" (it is up to you to implement)

    Implement "keyPressEvent" and wait for "Qt::Key_F1"

    The rest is up to you...


  • I have the downstream documentation files in qt format and it works well with my kewords. But isn't QTextCursor only for QTextDocument? I want to act on widgets tooltips.

    Anyone else with some ideas?

  • Nope, it is supported by "QTextEdit":, etc. (AFAIK, all Qt classes that were designed to edit texts support this)
