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 (using the '|' operator) 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, "ComboBoxGadget", #PB_Window_SystemMenu | #PB_Window_ScreenCentered) 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 a
SetGadgetState(1, 2) ; set (beginning with 0) the third item as active one
Repeat : Until WaitWindowEvent() = #PB_Event_CloseWindow
EndIf
