check box and signal

[mickey]

Hi, I'm trying to do this:

connect( checkBox, SIGNAL(toggled(bool)), this, SLOT (activeOption() )); 
connect( checkBox2, SIGNAL(toggled(bool)), this, SLOT (activeOption() ));

connect( checkBox, SIGNAL(toggled(bool)), this, SLOT (activeOption() )); 
connect( checkBox2, SIGNAL(toggled(bool)), this, SLOT (activeOption() ));

To copy to clipboard, switch view to plain text mode 

problem is that check box belog to button group exclusive of 2 check box; When I active check1 start my SLOT and SLOT starts a second time because when checking the fisrt box, I de-checking the second too (is exclusive); I need something like:
connect( checkBox2, SIGNAL(checked()).....but it is not a signal?
is there a signal?
Thanks

emm..why you dont want get bool flag(checked/unchecked) in your slot

Since you have the check boxes in a button group, you can use:
QButtonGroup::clicked(int id) [signal]

At least in Qt4, the corresponding signal is emitted for the check box that was "checked".

because I'd like the SLOT starts only when checkBox is checked and avoid control of a bool inside SLOT; I resolve so:

connect(buttonGroupEquation, SIGNAL(clicked(int)), this, SLOT (activeOption(int) ));

connect(buttonGroupEquation, SIGNAL(clicked(int)), this, SLOT (activeOption(int) ));

To copy to clipboard, switch view to plain text mode 

clicked(int) say to SLOT who is the sender too; Thanks

Is it possible to change checked window's contens (caption and icon) regarding to this button check state? I mean, how do I rewrite non virtual slot to do this?

Could you elaborate a bit? What is a checked window? What non-virtual slot?

Ok, here we go:

The checked button term is used in qt QPushButton documentation and it refers to a button, which supports toggle button. And here is my problem, since i do not know how to make a code that will:

1) in button state ON set a predefined text and icon
2) in button state OFF set a different predefined text and icon

Construct a QIcon with two pixmaps, one for each state. To update button text, you can simply connect to toggled(bool) signal and set the button text in the corresponding slot, or you can reimplement for example QAbstractButton::checkStateSet() and change the button text there.
