Custom widget plugin installation[SOLVED]
-
i am using qt 5.0 on windows 7
-
yeah but now actually the plugin is loading but when building the project the compiler shows no such directory sign on my class
and is not including the header -
What IDE are you using ?
-
i am using qt creator only
-
Did you check that your class related files is listed in your pro file ?
-
how do you do that can you please help with the command
-
mainwindow.obj:-1: error: LNK2001: unresolved external symbol "public: virtual void * __thiscall LED::qt_metacast(char const *)" (?qt_metacast@LED@@UAEPAXPBD@Z)
THIS IS THE ERROR IT IS SHOWING WHILE BUILDING NOW I INCLUDED THE PATH IN THE .PRO FILE
-
What is LED ?
Please, don't write all in upper case, it's considered as shouting and a bit rude.
-
sorry
it was by mistake and LED is my class name -
Can you post your pro file ?
-
QT += core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = tester
TEMPLATE = app
#LIBS +=-L"C:\Qt\Qt5.0.1\Tools\QtCreator\bin\tester" -l"customwidgetplugin"
SOURCES += main.cpp
mainwindow.cppHEADERS += mainwindow.h
FORMS += mainwindow.ui
INCLUDEPATH += "C:\Qt\Qt5.0.1\5.0.1\msvc2010\examples\designer\customwidgetplugin"LIBS += $$(QTDIR)\plugins\designer\customwidgetplugin.lib
this is my pro file though it has now a different widget but the same error occurs. i have experimentes a lot with the library path.
the linker error when the library path is added dissapears and the program starts but terminates unexpectedly instantly without any specific error message ang if the library path is not given the linker error arises
-
Before going further, follow the suggestion Tobias Hunger made on your other plugin related post.
-
thank you for all your help and patience.
the plugin is now working -
and i would just like to ask if you could also help me with my other question you looked upon the custom menubar kind of widget and did you have any ideas

I've responded, in between, you can mark this thread as solved since it's working so other forum users may know a solution has been found. Adding a link to the post where you had the helping answer would also be a plus.

I am adding the link to the post that helped me solve the error and i would also like to add that one more conmon mistake that was not written in the post could be the mixing of debug and release files we need the the release dll to add in the designer and the debug dll to set as the library path in the pro file so both dll are required"Your text to link here...":http://qt-project.org/forums/viewthread/33712/
