c++ - Fit the width of the view to longest item of the QComboBox -

i've got qcombobox contains long strings. long means strings wider width of qcombobox on gui. in case qt display items in way:

previously working matlab has less user friendly gui drop-down list think matlab solution better:

is there easy way achieve similar result in qt or have setup custom model , view purpose ?

i've done few years back. should working fine.

//determinge maximum width required display names in full int max_width = 0; qfontmetrics fm(ui.comboboxnames->font()); for(int x = 0; x < nameslist.size(); ++x) {     int width = fm.width(nameslist[x]);     if(width > max_width)         max_width = width; } if(ui.comboboxnames->view()->minimumwidth() < max_width) {     // add scrollbar width , margin     max_width += ui.comboboxnames->style()->pixelmetric(qstyle::pm_scrollbarextent);     max_width += ui.comboboxnames->view()->autoscrollmargin();     // set minimum width of combobox drop down list     ui.comboboxnames->view()->setminimumwidth(max_width); }
