QComboBox hide top item from list

[karankumar1609]

Hello,

I have a problem with Qt Combobox.
I have added three item in comboBox : "Show" , "View", "Download"
Here "Show" is the permanently visible item for combobox even if i click on "View" or "Download".
But the problem is whenever popup of combobox comes it shows all three items i dont know how to hide the "Show" option in my list.
Please any idea about that?

Assuming that you want to remove/hide "Show" on some event, you have to do the following -


removeItem(int index); // for removing
insertItem(int index, QString item);// for inserting back
//index is 0 for first item

Thanks for your quick reply but i have done it via



QMenu* showToolMenu = new QMenu(ui->button_Show);
showToolMenu->addAction("View", this, SLOT(on_button_file_Download_clicked()));
showToolMenu->addAction("Download", this, SLOT(on_button_file_View_clicked()));
ui->button_Show->setMenu(showToolMenu);


but now i got stucked in a problem.
when i run this code, there is an arrow icon visible on button.
please let me know how to remove arrow icon from button.

That arrow suggests that the button has a menu, nothing else. It's an indication to the user that on press of the button, a pop-up menu will be showed.

If you want get rid of the arrow (assuming you have QToolButton) you can call:

ui->button_Show->setPopupMode (QToolButton::InstantPopup)
Although be aware that

In this mode, the button's own action is not triggered.

ui->button_Show->setPopupMode (QToolButton::InstantPopup)

QPushButton#evilButton::menu-indicator {
