Description

When setting invalid index for a WComboBox programmatically, the first item in combo box will be displayed as selected instead.

Repro:

Wt::WComboBox *combo = new Wt::WComboBox(this);
combo->addItem("Apples");
combo->addItem("Oranges");
combo->setCurrentIndex(-1); // ERROR: it will display "Apples" instead of an blank field

Please find attached a patch proposal; it works fine for me, but Wt team might want to tweak it to make it more efficient.

Regards.

Hey,

Contrary to what I've been thinking until now, it is indeed supported in most browsers to have 'no selection' in a combo-box (but only using JavaScript).

I've made a change so that setting currentIndex to --1 works properly now.

Thanks for pointing this out.

Regards,
