Desktop Popup Menu

From Xojo Documentation

Popup Menu Library Icon

Popup Menu controls are useful when you have a single column of data to present in a limited amount of space. It presents a list of items and the user can choose one item. On macOS, when the user displays the Popup Menu’s items, the selected item is indicated by a checkmark.

Use the Set Default Value feature to add the default values that will appear in the list, one value per line.

Refer to PopupMenu in the Language Reference for details on all its events, properties and methods.

Below are the commonly used events, properties and methods.

Handling Focus

On Windows, when a PopupMenu receives the focus if the currently selected item is highlighted. It responds to the up and down arrow keys and provides the type selection functionality. For example, if the user types an “O” while the PopupMenu has the focus, the first entry with an “O” in it is highlighted. When a PopupMenu gets the focus on Linux, the currently selected item is highlighted. You can change the selected menu item with the up and down arrow keys.

Usage

This code in the Popup Menu Open event handler adds map directions to it:

Me.AddRow("North")
Me.AddRow("South")
Me.AddRow("East")
Me.AddRow("West")

This code in the Change event handler displays the selected direction:

If Me.ListIndex >= 0 Then
MsgBox(Me.List(Me.ListIndex))
End If

This could also be written more simply as:

MsgBox(Me.Text)
