connect

[mickey]

Hi, I'd like to know if there's a way to do this below with ONE connect :


connect(buttonGroupLL, SIGNAL(clicked(int)), tabWidget3, SLOT(EnableTab(int)); //??enableTab?
connect(buttonGroupLL, SIGNAL(toggled(bool)), tabWidget3, SLOT(setEnabled(bool));

In other word: I've 3 checkBox that when they're clicked, they have to enable tab1,tab2,tab3 (tabs of tabWidget3).
Wich is the best way to do this? Thanks

Several ways to achieve this
A) built on the code you wrote... to get one connect at last end...

1- create a custom signal from the groupbox that transmits an int
2- create a slot for each of the checkboxes in the groupbox that accepts a bool and emits the signal created above with correct int for the tabpage
3- create a custom slot on the tabwidget that enables/disables the page that the recieving int is.

this would make the checkboxes connected to the groupbox, the groupbox connected to the tabwidget and the tabpages get a signal from the tabwidget.

line drawing


Checkbox(bool) ----| |--- Tabpage(bool)
Checkbox(bool) ----|--- Groupbox(int) -- Tabwidget(int) ---|--- Tabpage(bool)
Checkbox(bool) ----| |--- Tabpage(bool)


B) easier. several connects :D

connect each checkbox to each tabpage directly


connect(checkbox1, SIGNAL(clicked(bool)), tabpage1, SLOT(setEnabled(bool)));
connect(checkbox2, SIGNAL(clicked(bool)), tabpage2, SLOT(setEnabled(bool)));
connect(checkbox3, SIGNAL(clicked(bool)), tabpage3, SLOT(setEnabled(bool)));

cheers,

I don't understand first solution.This below is ok.
But I need also know wnen checkbox is toggled or not (to enable/disable tab widget)
This below send right number of tab to be enabled/disabled. But EnableTab don't know if must enble or disable....


connect(buttonGroupLL, SIGNAL(clicked(int)), tabWidget3, SLOT(EnableTab(int));
