Lazarus Windows ist OK.
Lazarus macOS Carbon is OK.
Lazarus macOS cocoa: the combobox list does not open on typing something into the field.
Does anyone have an idea for a workaround?
The goal is: the user types something and the system searches at each keypress an external source (internet, database, ...), if it finds something containing the text in the field. If there is something, the corresponding phrases are filled into the itemlist of the combobox, so the user can select one. Everything works as desired, but the user cannot see, that there is something, since the dropdown list remains closed.
