B4J Question How do I iterate through/reference my open windows (Forms)?

[MrKim]

Users will have multiple windows open. Note I am opening multiple copies of the same Form. I need to check if a particular one is open. If not Open it. If it is, bring it to the front.

Thanks for your help.

Best way is to maintain a Set with the active forms:

Sub Process_Globals
    Private fx As JFX
    Private MainForm As Form
    Public ActiveFormsMap As B4XSet
End Sub

Sub AppStart (Form1 As Form, Args() As String)
    ActiveFormsMap = B4XCollections.CreateSet
    MainForm = Form1
    MainForm.RootPane.LoadLayout("1")
    ShowForm(MainForm)
End Sub

Sub MainForm_Closed
    FormClosed(MainForm)
End Sub

Public Sub ShowForm(frm As Form)
    ActiveFormsMap.Add(frm)
    frm.Show
End Sub

Public Sub FormClosed(frm As Form)
    ActiveFormsMap.Remove(frm)
End Sub

Call ShowForm whenever you want to show a form and call FormClosed from the Closed event of all forms.
