Qt4.5 windows TextFind tutorial not working

[wysota]

Do you get any warnings in the console about the connect() statements? How do you know the code doesn't work?

[czlowiekcien]

QObject::connect(ui->pushButton,SIGNAL(clicked()),this,SLOT(huj()));
this is compiling but nothing happens when I press the button, the button even not going down (is freeze).
QObject::connect(ui->pushButton,SIGNAL(clicked()),ui,SLOT(huj()));

is saying "no maching function for call..."
in creator I cant set connection by clicking becouse he didnt see my slots

I have good news
QObject::connect(ui->lineEdit,SIGNAL(returnPressed()),this,SLOT(huj()) );

this is working, but why manualy connected button with signal clicked not working? and why on_pushButton_clicked() is not connecting automatycaly even if I use //QMetaObject::connectSlotsByName(this);

that metod is the last method in setupUi so i dont must to type it. what is wrong here?

[wysota]

Can we see the whole message you are getting?

[czlowiekcien]

when i using
QObject::connect(ui->pushButton,SIGNAL(clicked()),ui,SLOT(huj()));

widget.cpp:12: error: no matching function for call to `Widget::connect(QPushButton*&, const char*, Ui::Widget*&, const char*)'

M:/Qt/projekty/textfajnd/TextFind/../../../2009.02/qt/include/QtCore/../../src/corelib/kernel/qobject.h:202: note: candidates are: static bool QObject::connect(const QObject*, const char*, const QObject*, const char*, Qt::ConnectionType)

M:/Qt/projekty/textfajnd/TextFind/../../../2009.02/qt/include/QtCore/../../src/corelib/kernel/qobject.h:308: note: bool QObject::connect(const QObject*, const char*, const char*, Qt::ConnectionType) const


that is working well
QObject::connect(ui->lineEdit,SIGNAL(returnPressed()),this,SLOT(huj()) );

now I`m confused 7 hour of searching what is wrong for nothing. I create another button and it was working fine so I check properties and was everething the same so I delete first button and create it again and it is working. so admin can close that subject. thanks for helping

[wysota]

Hmm... you said it was working well - I thought you found the problem. If not then I can tell you what was wrong - "ui" is not a widget thus passing "ui" as the third parameter to connect() is illegal.

[czlowiekcien]

I type ui there becouse I trying to find any way to solve my problem I know that was wrong but I still dont know why I had that problem. maybe Qt Creator is not the best tool

[wysota]

Qt Creator is just a text editor, it doesn't make syntax errors - you do
