Qtabwidget addtab duplicates tab on second click
-
Hello
I have two buttons with two slots, on click I add a new tab to my qtabwidget, this works. However, It only works the way I want if I have one button, I can click multiple times it won't duplicate the tab, but If I click the second button which creates a second tab, then click the first button it duplicates the tab. If I come back to second it duplicates too. And it keeps duplicating. I would like to know how I can prevent from duplicating on second click. Thanks
my code:bool MainWindow::control_tab(QString addst){ bool kontrol = false; for(int i=0; i < ui->open_tools_tab->count(); i++) { if(addst == ui->open_tools_tab->tabText(i)) { kontrol = true; } else if (addst != ui->open_tools_tab->tabText(i)) { kontrol = false; } } return kontrol; } void MainWindow::on_tB_add_students_clicked() { addst = "Add student"; if (control_tab(addst) == true) { for(int i=0; i < ui->open_tools_tab->count(); i++) { if(addst == ui->open_tools_tab->tabText(i)) { ui->open_tools_tab->setCurrentIndex(i); }} ui->tab_menu->setCurrentIndex(1); } else { ui->open_tools_tab->addTab(new QWidget(), icon, addst); } } void MainWindow::on_tB_add_teachers_clicked() { addst = "Add teacher"; if (control_tab(addst) == true) { for(int i=0; i < ui->open_tools_tab->count(); i++) { if(addst == ui->open_tools_tab->tabText(i)) { ui->open_tools_tab->setCurrentIndex(i); }} ui->tab_menu->setCurrentIndex(1); } else { ui->open_tools_tab->addTab(new QWidget(), icon, addst); } } -
What are you trying to achieve? Only adding the tab once? Then you should fix your control_tab() function to return true once the tab with the given name is found.
