c++ - QTWidget displays twice on just one click -
i have qdialog following:
and 1 gets triggered when click "ok" without selecting image , classifier files both, here
i have linked browse... buttons qfiledialog. now, when click on browse image button, opens file dialog, when select file , press ok, reopens it. same thing happens other browse button , dialog containing label.
any idea, why happening 2 times when event has occurred once?
here slots:
void mysecondqtproject::on_pushimage_clicked() { image = qfiledialog::getopenfilename(this, tr("open file"), "c:/users/mankum93/documents/visual studio 2013/projects/bananaclassifieropencv/bananaclassifieropencv", "images (*.png *.xpm *.jpg)"); } void mysecondqtproject::on_pushclassifier_clicked() { classifier = qfiledialog::getopenfilename(this, tr("open file"), "c:/users/mankum93/documents/visual studio 2013/projects/bananaclassifieropencv/bananaclassifieropencv", "xml files (*.xml)"); } void mysecondqtproject::on_pushok_clicked() { accept(); //now lets compare invalidity of string: if (image.isnull() || classifier.isnull()) { showerrordialog dialog(this); dialog.exec(); } else { //convert qstring std::string string imagefilename = image.tolocal8bit().constdata(); string cascadefilename = classifier.tolocal8bit().constdata(); // now, can go main detection logic detectobject(imagefilename, cascadefilename); } } ps: newbie qt
edit 1: meta object code
void mysecondqtproject::qt_static_metacall(qobject *_o, qmetaobject::call _c, int _id, void **_a) { if (_c == qmetaobject::invokemetamethod) { mysecondqtproject *_t = static_cast<mysecondqtproject *>(_o); switch (_id) { case 0: _t->on_pushimage_clicked(); break; case 1: _t->on_pushclassifier_clicked(); break; case 2: _t->on_pushok_clicked(); break; default: ; } } q_unused(_a); } edit2 : code ui files
