[Qt-interest] program execution issue

[Malyushytsky, Alex]

I normally don't  use Designer to anything except widget design, skipping slots creation and connection in Qt4 , so I might be wrong.
But according to my impression this message means that you are trying to connect slot which does not exist in QDialog using the pointer to QDialog.

I assume TeacherForm is a  pointer to QDialog. In this case this is a problem. To make this code work you can crate your own class CTeacherForm (derived from  QDialog ), add openColorDialog() slot there  and promote QDialog in QtDesigner to CteacherForm.

If  TeacherForm is already a subclass of QDialog, check that slot openColorDialog() exist,  Q_OBJECT macro is defined, etc.

Hope this helps,
            Alex Malyushytsky

Subject: [Qt-interest] program execution issue

Hi,

I have QDialog Widget created in Qt Designer, this dialog contains a button that open a QColorDialog box. So I've created a slot called openColorDialog() in designer that I attached to the clicked() signal.
The compilation of the program goes without error, but when I run the program and click on that button nothing heppen and the application output window of qt creator displays the following message:

Object::connect: No such slot QDialog::openColorDialog() in Interface\/ui_teacherform.h:121
Object::connect: (sender name: 'toolButton')
Object::connect: (receiver name: 'TeacherForm')

The QDialog has also others slots that are correctly executed when the corresponding signal arises.

In the line 121 of the ui_teacherform.h this code:
QObject::connect(toolButton, SIGNAL(clicked()), TeacherForm, SLOT(openColorDialog()));

I'm suspecting the "\/" symbole in the pathname.

Any help is welcom.

Cheers.
