Call function by change index in combobox
I want to call a function by changing Current index in my ComboBox
I wrote this code :
void publisher::on_cmb_subj_currentIndexChanged(const QString &arg1)
but this is not work!!
What is the name of your combobox?
Personally, I prefer to connect my signals and slots explicitly. Did you connect yourself, or...? And you did connect yourself, what did the connect statement return?
my combobox name is cmb_subj
i like to use connect signals and slots.
how can i connect my cmb_subj signal (current index changed) and my slot call a function.
AFAIK, underscores result in problems with automatic signal-slot connection. One of the reasons I don't like that mechanism at all...
Instead, just explicitly connect the signal to the slot in your constructor (just after the ui.setupUi(this); call), and it will work. If you need help with the syntax, refer to the [[doc:QObject]] documentation.
