problem with emiting a signal

[msmihai]

Hello everybody. I'm just testing how to emit a custom signal . For example, i have a button and , when I press it, ai want a signal called MySignal to be emited. I've done that quite easy

emit MySignal();

emit MySignal();

To copy to clipboard, switch view to plain text mode 

I now declare this signal in the "h" file :

signals:
	void MySignal();

signals:
	void MySignal();

To copy to clipboard, switch view to plain text mode 

The problem is in the "cpp" file where i define this signal:

void App1::MySignal()
{
}

void App1::MySignal()
{
}

To copy to clipboard, switch view to plain text mode 

When it compiles it gives the following error:

tmp/obj/release_shared/moc_app.o(.text+0x60):moc_app.cpp: multiple de
 `App1::MySignal()'
tmp/obj/release_shared/app.o(.text+0x0):app.cpp: first defined here

tmp/obj/release_shared/moc_app.o(.text+0x60):moc_app.cpp: multiple de
 `App1::MySignal()'
tmp/obj/release_shared/app.o(.text+0x0):app.cpp: first defined here

To copy to clipboard, switch view to plain text mode 

What seems to be the problem ?

you don't need to implement signal, the moc does it. you need just emit a signal like this

....
connect(myButton, SIGNAL(clicked()), this, SIGNAL(processButtonClick()));
....
void App::processButtonClick()
{
...
emit MySignal();
...
}

....
connect(myButton, SIGNAL(clicked()), this, SIGNAL(processButtonClick()));
....
void App::processButtonClick()
{
...
emit MySignal();
...
}

To copy to clipboard, switch view to plain text mode 

or in your case (of cource if you don't need to process a button click)

...
connect(myButton, SIGNAL(clicked()), myWidget, SIGNAL(MySignal()));
...

...
connect(myButton, SIGNAL(clicked()), myWidget, SIGNAL(MySignal()));
...

To copy to clipboard, switch view to plain text mode 

myWidget -- is the widget which has MySignal.
