I'm creating my first app with my own slot .
Everything goes sooo fine till now . However when I want to create my own slot , nothing is happened (i.e. slot didn't work !! )

The purpose of my App : when the user press a button , an empty .txt file 'll be created .

I'm working under MS Win XP , & I've tried to run it over Linux to find out the problem . I've such that output :

Object::connect: No such slot QDialog::Custom()
Object::connect: (sender name: 'pushButton')
Object::connect: (receiver name: 'Form')

Though , I've add such this slot "Custom" @ QTDesign .

I've got .exe BUT the slot never responds ( i.e. Createing the file )

I've added a little piece of code @ the header file which was generated , is that true !!
I'm using :
- qt-win-opensource-4.4.0
- qmake to build the project
-MinGw
N.B. : I've created the slot , according to what I've understand from QT Assistant

So , What' the problem @ My Code :
