QFileDialog::getOpenFileName

[meikelneit]

Hello,

i have a Problem with this function. I am Looking to get a Directory of a file to open it later on.

QString l_filePath = QFileDialog::getOpenFileName(this,tr("open directory"),QDir::homePath(),("*.db"));

but how can i react on the different Buttons beeing pushed. When the OK button is pushed i want to execute another Funktion, how can i do that?

Hi
@meikelneit said in QFileDialog::getOpenFileName:

but how can i react on the different Buttons beeing pushed.

Connect buttons 'clicked' signal to the method you want to call
see signals & slots doc

QPushButton *okBtn = new QPushButton("ok", this);
QObject::connect(okBtn,&QPushButton::clicked,this, &ClassName::slotName)

Doesn't this function open a static Dialog??
So how can i connect the button inside with a Signal?

Hi
with QFileDialog::getOpenFileName static call, if user press Cancel or close X the
returned string will be empty.

QString l_filePath = QFileDialog::getOpenFileName(this,tr("open directory"),QDir::homePath(),("*.db"));
if ( ! l_filePath.isEmpty()  ) { // if user did select something
....
}
