Using variables to acces UI
-
HI Guys,
I'm new to QtI have about 50 buttons in my UI, and I need to modify them if the certain condition is met,
void aaa::on_push_button1_clicked()
{
ui->pushButton_00->setEnabled(true);
}this one works well, but so I wil have to manually check for every button, so I want to replace pushButton_00 with a variable, but I can't get it to work

Hi and welcome
There is a special sender() in a slot you can use to know which button was the sender of
the clicked() signalvoid aaa::on_push_button1_clicked()
QPushButton *butt=qobject_cast<QPushButton *> ( sender() ) ;
if (butt) {
}that way u can use a variable and not ui->NAME
All you buttons should be connected to same slot then.
You could do that after setupUI()
QList<QPushButton *> list = this->findChildren<QPushButton *>();
foreach(QPushButton *b, list) {
connect(b, XXX
}
