[rajeshclt3]

Hi,

When we resize the QComboBox to bigger size,drop down arrow of combo box becomes big sync with combo boz size but vertical Scroll bar's width is small (default size).How can we increase the width of combo box sync with Combo box's size .This behavior is on panels.Please give any suggestions.

Thanks

that drop down menu is the listview

QComboBox:: view()->width()

QComboBox:: view()->width()

To copy to clipboard, switch view to plain text mode
