Details
Constructors
DropDownList<T>()
Properties
OptionFormat
Specifies how to format the SelectedOption in the label text.
Property Value
OptionMaxLines
Maximum number of lines to allow per option in the drop-down list.
Property Value
Remarks
Setting this allows options in the list to wrap lines instead of being truncated to one line. Applies only to the open list, and not the selected item text within the main border, which is always single-line.
OptionMinWidth
Minimum width for the text area of an option.
Property Value
Remarks
If this is 0, or if all options are larger, then the dropdown will expand horizontally.
Options
The options available to select.
Property Value
SelectedIndex
Index of the currently-selected option in the Options, or -1 if none selected.
Property Value
SelectedOption
The option that is currently selected, or null if there is no selection.
Property Value
T
SelectedOptionText
The text of the currently-selected option.
Property Value
SelectionFrameLayout
Customizes the layout settings of the selection frame.
Property Value
Remarks
The selection frame is the frame surrounding the text of the selected item, not including the dropdown button (arrow) itself which is fixed size. By default, the selection frame matches the width of the selected item text; this can be changed, for example, to stretch to the available layout width, minus the button.
Methods
CreateView()
Creates and returns the root view.
Returns
Measure(Vector2)
Performs layout on this view, updating its OuterSize, ActualBounds and ContentBounds, and arranging any children in their respective positions.
Parameters
availableSize Vector2
The width/height that is still available in the container/parent.
Returns
Whether or not any layout was performed as a result of this pass. Callers may use this to propagate layout back up the tree, or perform expensive follow-up actions.
Remarks
Most views should save the value of availableSize for use in IsDirty() checks.
Events
Select
Event raised when an item in the list is selected.
