Porting Application from Qt designer 4.5.2 to Qt creator creating problem

[jsmith]

Hi,
I have been working on Qt.4.5.2 for last six months. Recently i have shifted to Qt Creator.
I have executed applications which were developed in Qt designer 4.5.2 successfully in Qtcreator. Now if i will make any small changes in ui files (ex:put one label) through QtCreator ,application is not running as per code(No errors). For example i have derived one class from QWidget. In that constructor is calling, but paint event is not calling.

i have one more doubt. Is it sufficient to install Qt creator or is it required to configure qt which is in Qtcreator folder.

can anyone help me please

regards

I have trouble understanding what it is you are trying to say.
What do you mean by "applications which were developed in Qt designer"?
You can't develop applications with Qt designer, only prototype UIs with it.
