not compiling

[sudheer]

hi friends , the project given in below link is not compiling

http://sector.ynet.sk/qt4-tutorial/m...plication.html

i don't know y it is not compiling...... (may be due to Qt version)
i am using Qt 4.3.2( linux X11)

it giving the error as " Ui" is not declared
pls clarify me , how compile that

What exact steps did you perform to create and build the project? Did you use qmake? Did you create a form in Designer? Did you inform qmake about the form? Did you include the proper file generated by uic?

[sudheer]

i will explain procedure:-
1)selected c++ project file and named it "filebrowser6"
2)FILE->NEW-> Widget
and named the form as filebrowser6
3)FILE->NEW->c++ header file and paste the code as usual written in link(adding file to da project) named it "files.h"
4)FILE->NEW->c++ source file(for constructor definition) and paste the code as usual written in link, named it "files.cpp"
5)FILE->NEW->c++ source file(for main.cpp) and paste the code as usual written in link
6)Included the header file in "include Declaration"
7)Included the some QT header files in "include Implementation"
8)saved all
9)In terminal, typed as "qmake filebrowser6.pro"
10)and "make"

your que's

yes I included the "filebrowser6.ui.h" in "files.h" header file which is generated by .ui
yes I created the form in Designer
yes i use qmake

after comipling errors


[sudheer@localhost filebrowser6]$ qmake filebrowser6.pro
[sudheer@localhost filebrowser6]$ make
Makefile:157: warning: overriding commands for target `moc_files.cpp'

In file included from main.cpp:2:
files.h:6: error: `Ui' has not been declared
files.h:7: error: expected class-name before '{' token
make: *** [main.o] Error 1

i also attached project in zip format

so plz clarify me thanks

You are mixing Qt3 and Qt4 here. You use qmake from Qt3, you have written Qt3 code yourself, but the "files" class is created like it was a Qt4 class. Either switch KDevelop to use Qt3 instead of Qt4 or switch yourself to Qt4.

so wat should i do, i have downloaded "qt-x11-opensource-src-4.3.2" version,
and i working on Red hat Enterprise Linux4 version,

as i am new to the QT i don't have much knowledge about this, so plz explain me in detail
how i integrate designer form file with my source files and how to make the project and make

But i can able to design simple GUI applications and making it without any errors, like just creating slots and defining its functions in ".ui.h" file and connecting these slots to 'pushbuttons, lineedit, so on...'

Go to our wiki and read the articles you might find useful. Also take a look at the tutorial present in Qt reference manual.

".ui.h" file are a Qt3 concept that is not present in Qt4 anymore.

than q u very much , the tutorial in wiki is really worthy
now i can able to compile that(myapplication, in the link) project quite easily

actually wat happends is during the Qt4.3.2 installation, i left the computer over night so qmake is configured to qt3.3 that's da mistake i had done
