The Height parameter should be a larger value than the main body of the gadget, since it also sets the height of the drop down list part of the ComboBox.
You can add a 'mini help' to this gadget by using GadgetToolTip().
The following commands can be used to act on the list contents:
- AddGadgetItem(): Add an item.
- GetGadgetItemText(): Returns the gadget item text.
- CountGadgetItems(): Count the items in the current combobox.
- ClearGadgetItemList(): Remove all the items.
- RemoveGadgetItem(): Remove an item.
- SetGadgetItemText(): Changes the gadget item text.
- GetGadgetState(): Get the index (starting from 0) of the current element.
- GetGadgetText(): Get the (text) content of the current element.
- SetGadgetState() can be used to change the selected element.
- SetGadgetText(): Set the displayed text. If the ComboBoxGadget is not editable, the text must be in the dropdown list.
'Flags' are always optional and can be composed of one of the following constants:
#PB_ComboBox_Editable : Makes the ComboBox editable #PB_ComboBox_LowerCase : All text entered in the ComboBox will be converted to lower case. #PB_ComboBox_UpperCase : All text entered in the ComboBox will be converted to upper case.Example:
If OpenWindow(0,0,0,270,140,#PB_Window_SystemMenu|#PB_Window_ScreenCentered,"ComboBoxGadget") And CreateGadgetList(WindowID(0))
ComboBoxGadget(0,10,10,250,100,#PB_ComboBox_editable)
AddGadgetItem(0,-1,"ComboBox editable...")
ComboBoxGadget(1,10,40,250,100)
For a=1 To 5 : AddGadgetItem(1,-1,"ComboBox item "+Str(a)) : Next
SetGadgetState(1,2) ; set (beginning with 0) the third item as active one
Repeat : Until WaitWindowEvent()=#PB_Event_CloseWindow
EndIf
