    How did you install Qt ?

  • @SGaist with online installer .... firs I have install all library and control missing dependancy.... desktop version with mark all in QT5.5 option, tool option, and other option pre-marked....

    N.B. I try to install other example from qt creator 3.6 .... all example with widget module in .pro file it do the same error ....

    Thanks for your interest

    Strange, can you check whether that file can be found in your Qt installation ?

  • Searching in my installatio i find these file ...... QDesignerCustomWidgetInterface(plain text) inside there is these note:

    #ifndef DEPRECATED_HEADER_QtDesigner_QDesignerCustomWidgetInterface
    #define DEPRECATED_HEADER_QtDesigner_QDesignerCustomWidgetInterface
    #if defined(__GNUC__)
    #  warning Header <QtDesigner/QDesignerCustomWidgetInterface> is deprecated. Please include <QtUiPlugin/QDesignerCustomWidgetInterface> instead.
    #elif defined(_MSC_VER)
    #  pragma message ("Header <QtDesigner/QDesignerCustomWidgetInterface> is deprecated. Please include <QtUiPlugin/QDesignerCustomWidgetInterface> instead.")
    #include <QtUiPlugin/QDesignerCustomWidgetInterface>
    #if 0
    #pragma qt_no_master_include

    is in /myhome/qt/5.5/gcc_64

    Sorry for big caracters .. is imported from .txt file


    [edit: fixed coding tags SGaist]

  • I try to add to mu .pro file several lines:

    INCLUDEPATH += /home/Qt/5.5/gcc_64/include
    INCLUDEPATH += /home/Qt/5.5/gcc_64/plugin/designer
    INCLUDEPATH += /homeQt/5.5/gcc_64/bin

    without success..

    Did you follow what was suggested and use #include <QtUiPlugin/QDesignerCustomWidgetInterface> ?
