Connecting signal to button

[steg90]

Hi,

I've got this strange warning on one of my ui forms :

'Warning : The project doesn't contain any class which uses this form!'

Very strange as it does, anybody had this error before?

All I am trying to do is connect a signal to a QPushButton!

Regards,
Steve

When do you get the error and how does your project file look like?

[steg90]

I get the error when I double click on my QPushButton on the form.

Project file is built within Visual Studio.net. I've never had this problem before?

You mean you get the warning while the application is running? Without seeing the .pro file we won't be able to help much.

I get the warning while I'm editing the form in visual studio.net.

Hello.
I work with QT 4.2 and Visual Studio 2005. Now there is a strange situation. I try to connect a signal to an element of a form and see the message: 'Warning. The project doesn't contain any class which uses this form!' (in attachment)
There was the same guestion some weeks ago... but without answer unfortunately

Sometimes the message disappears but more often I see it again when I'm trying to connect a signal. Hitherto I couldn't find any logic in its behaviour....

Hmm, you don't connect signals by double clicking. When you double click a child widget of a form the integration attempts to insert a slot stub with naming convention of automatic connections. Now, if there is no relevant class, or the integration is unable to detect where the form is being used, such error makes sense.

I get the error when I double click on my QPushButton on the form.

Most likely the message appeared not only in case of double clicking. I got it when I tried to use functionality 'Connecting Signals & Slots'. It seems to me I found the reason of the mistake in my case. A namespace was used there.... in such way

namespace Space
	{
		class  TNewDlg : public QWidget
		{
 
     private:
			Ui::TNewDlgClass ui;
..........

namespace Space
	{
		class  TNewDlg : public QWidget
		{

     private:
			Ui::TNewDlgClass ui;
..........

To copy to clipboard, switch view to plain text mode 

Probably that's why the integration couldn't find relevant class.... I refused from using namespace and it works correctly now (at least I hope so )
