text: UI file can't find customer widget .h file
  Hello every one I was trying to add the source code to my project.
  source code :
  and I change the class name to fit my project.
  but the following error exist :
  .../ui_texteditor.h:24: error: mtextedit.h: No such file or directory #include "mtextedit.h" ^
  part of ui_texteditor.h :
  #include <QtWidgets/QSpacerItem> #include <QtWidgets/QToolButton> #include <QtWidgets/QVBoxLayout> #include <QtWidgets/QWidget> #include "mtextedit.h" //<---error part QT_BEGIN_NAMESPACE class Ui_TextEditor { public: QVBoxLayout *verti
  I just changed the mrichtextedit class --> texteditor class
  and I changed the .ui file and the filename as well.
  anything I missed??

  Hi,
  What exactly did you change ? Only the class name or also the matching files ?

  Ui_texteditor.h file is generated file. U should not modify this. Any reason u r adding the file entry ?
  Hi all,
  I tried not to changed any things of the code again.
  And copy the code to my project for use.
  But the issue still appeared.
  the file I copy to my project:
  - mrichtextedit.ui
  - mrichtextedit.h mrichtextedit.cpp
  - mtextedit.h mtextedit.cpp
  (in my mainwindow)
  MRichTextEdit * txtedit = new MRichTextEdit(this); // add it as one of the tab page tab->addTab(txtEdit, "tab1");
  Hey all,
  I got the point !
  I have to changed the headfile path in the Promote Widget setting form.
  Thanks a lot guys~
