[SOLVED] Custom widgets disappearing from design view after projects reopen.



  • Hi all,

    At the beginning I would like to say hello to everyone, this is my first post here.

    I am creating some library with several of custom widgets, everything goes fine until I closed and reopened my *.ui file. After file reopened (I mean close in editor and open again) on "design" view in qt creator I cannot see my widgets (there are blank) but I can move them and change their size. Most interesting thing is that after compile and run program widgets are visible.

    This picture presents how it looks before closing:

    This picture presents how it looks after reopening the UI file:
    !http://piotr.grabalski.gre.pl/qt/qt_issue_02.jpg(issue 02)!

    Do you have maybe any idea to fix that?

    Thanks in advance!

    regards,
    Peter



  • Okay, solved, thanks!


  • Moderators

    How did you solve this issue? Can you mark your thread as solved, please?



  • My mistake in subclass implementing QDesignerCustomWidgetInterface,

    method:
    @QString name() const;@
    was wrongly implemented, it should return a name of widget class.
    Designer put some errors in terminal (something about widget class name mismath),

    after all everything works,

    regards,
    piograb
