[solved] - How to create a GUI consisted of MdiArea as central widget and two docked widgets?



  • Hello all,

    I'm new to Qt programming framework. I would like to create a GUI interface with a MdiArea widget as its central widget and two other docked widget on the left and bottom.
    I can do this if I use stack widget or textEdit widget as its central widget, but I don't have any luck with Mdi widget as central widget.

    I would like to use MdiArea as central widget so that I’d be able to open multiple textEdit and TableView screens and organize them in cascade and tile format.

    I'm wondering whether it is not possible to have a combination of MdiArea as central widget and two docked widgets using Qt widgets and classes or there's something wrong with my code.

    Your help and feedbacks are highly appreciated.

    Hi and welcome to devnet,

    QMainWindow is what you are looking for.

    Search for the MDI example in Qt's documentation. It shows what you want to do with the MDI area. The dock widget part is covered in QMainWindow's documentation as well as QDockWidget's

    Hope it helps



  • Hi SGaist,

    Thanks for your reply. I have gone through MDI and QDockWidget examples. I can complie my code, but my application doesn't open and bug report window pops up when I run it.

    When I comment out createMenus() line my application opens, but when I close it bug report window pops up.

    Any idea what could cause this issue? Thanks

    Without any code it's pretty much Crystal Ball debugging. Please show the content of createMenus



  • Hi SGaist,

    After I created a cleen project, it worked. I think my project *.pro file was messed up.

    Thanks for your help and feedback
