How to use a QWidget created or defined by some programmer?

[jesse.zwd]

Hi, there.

I often see some customized QWidget written by programmer, for example :

MyComboBox::MyComboBox( QWidget * parent ) : QComboBox(parent)
{
}

MyCombobox is inherited from Qcombobox and not a standard QWidget provided By QT, I can't see it on the Design mode, how to use it graphically?

Thanks a lot!

Hi, koahnig, thanks for reply.

There are MyComboBox.cpp and MyComboBox.h, but no MyComboBox.ui.
I read some help documents where there are some words about "Promoting widgets" and some dialog titled "Promoted widgets".

Where is the "Promoted widgets" dialog? I have not found it.

Thanks again for your help!
