Implementations
Remove the item at the selected index and returns it. Panic of the index is out of bounds
Sort the inner collection by the display value of it’s items and update the view
Internally this uses Vec.sort_unstable_by
.
Return the index of the currencty selected item. Return None
if no item is selected.
Return the display value of the currenctly selected item
Return None
if no item is selected. This reads the visual value.
Set the currently selected item in the combobox. Does nothing if the index is out of bound If the value is None, remove the selected value
Search an item that begins by the value and select the first one found. The search is not case sensitive, so this string can contain any combination of uppercase and lowercase letters. Return the index of the selected string or None if the search was not successful
Add a new item to the combobox. Sort the collection if the combobox is sorted.
Insert an item in the collection and the control.
SPECIAL behaviour! If index is std::usize::MAX
, the item is added at the end of the collection.
The method will still panic if index > len
with every other values.
Update the visual of the control with the inner collection. This rebuild every item in the combobox and can take some time on big collections.
Set the item collection of the combobox. Return the old collection
Return the number of items in the control. NOT the inner rust collection
Return true if the control user can interact with the control, return false otherwise
Enable or disable the control
Return true if the control is visible to the user. Will return true even if the control is outside of the parent client view (ex: at the position (10000, 10000))
Show or hide the control to the user
Set the position of the button in the parent window
Get read-only access to the inner collection of the combobox This call refcell.borrow under the hood. Be sure to drop the value before calling other combobox methods
Get mutable access to the inner collection of the combobox. Does not update the visual
control. Call sync
to update the view. This call refcell.borrow_mut under the hood.
Be sure to drop the value before calling other combobox methods
Winapi class name used during control creation
Winapi flags required by the control
