For web applications, see WebPopupMenu.

Class (inherits from RectControl)

Displays a list of items when clicked. The user can select one item from the list. The ComboBox control is similar except that the user also has the option of typing an item instead of choosing one from the list of items.

Notes

NOTE: Changing the Height property has no effect for apps run on macOS. As a native control, macOS always draws the PopupMenu at its system-standard height.


Warning24.png The MouseDown and MouseUp event handlers are never called on Linux due to a limitation of the underlying GtkComboBox that is used. [1]


Warning24.png ContextualMenus do not work with PopupMenu on macOS due to a limitation of the underlying macOS control that is used.

Examples

This code in the Open event handler populates a popup menu and sets the initial value to the current month:

Dim months() As String = Array("January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December")
For Each m As String In months
Me.AddRow(m)
Next

Dim d As New Date
Me.ListIndex = d.Month - 1 // Select current month

Examine the value of ListIndex in the Change event handler to determine which item was selected.

This example adds an item to PopupMenu:

PopupMenu1.AddRow("October")

This example populates the RowTag identifier with a sequence number:

For i As Integer =0 To Me.ListCount - 1
Me.RowTag(i) = i
Next

Since RowTag is a Variant, you must first convert it to an Integer if you want to compare it to another integer. Do this with a simple assignment statement such as:

Dim recID As Integer
recID = PopupMenu1.RowTag(1)

Then compare recID to another Integer.

This example opens a new window when an item is chosen.

Sub Change()
Dim w As ListEditorWindow

If PopupMenu1.Text = "Edit List..." Then
w = New ListEditorWindow
End If

Changing the selected item in a PopupMenu:

PopupMenu1.ListIndex = 3 // Selects the 4th item in the list (0-based)

Displaying the RowTag of the selected menu item:

TexField1.Text = PopupMenu1.RowTag(PopupMenu1.ListIndex)
