window=CreateWindow( "ComboBox demo",0,0,350,200 ) combobox=CreateListBox( 0,0,128,100,window) textfield=CreateTextField(130,0,128,24,window) For k=0 To 9 AddGadgetItem combobox,"Item "+k Next SelectGadgetItem combobox,0 While WaitEvent(20)<>$803 If EventSource()=combobox SetGadgetText(textfield,"Item selected:"+SelectedGadgetItem(combobox)) EndIf Wend End Ok, this is a slightly modified version of the simple_combobox.bb example in the Mak folder. You can select different items with the mouse and the value shows up in the text area. But... if you change them with the arrow keys, it doesn't get updated. Is this a bug or am I doing something wrong? |

| Thanks! That's a handy work around - just what I needed. It's still a bit flakey when you hold the key down until it starts repeating though :( |
