Description
If High-DPI-Scaling is enabled QComboxBox item height differs for editable and non-editable comboboxes. For a 2560x1440 screen in my opinion the item height of non-editable QCombox is too large. The item height of editable QComboBox fits better for that resolution. Either way the item height should be the same for editable and non-editable QComboBox.
This issue might also affect other control-widgets that got listboxes.
An Qt 6.0 example application:
#include <QApplication> #include <QWidget> #include <QComboBox> #include <QStringList> #include <QLabel> int main(int argc, char *argv[]) { // Add this line if using Qt 5.15.2 // QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling). QApplication a(argc, argv); QWidget w; w.resize(470,305); QStringList stringList = {"Item1", "Item2", "Item3", "Item4", "Item5", "Item6", "Item7", "Item8", "Item9", "Item10"}; QLabel label1("ComboBox 1", &w); label1.setGeometry(22, 13, 150, 15); QComboBox combo1(&w); combo1.setGeometry(20,30,200,25); combo1.setFont(QFont("Roboto", 10)); combo1.addItems(stringList); QLabel label2("ComboBox 2 editable", &w); label2.setGeometry(252, 13, 150, 15); QComboBox combo2(&w); combo2.setGeometry(250,30,200,25); combo2.setFont(QFont("Roboto", 10)); combo2.setEditable(true); combo2.addItems(stringList); w.show(); return a.exec(); }
