B4J Question Trap key_event F8 and F10 in an B4J program

[Pietro Pancino]

HI all

I need to trap keyboard event in the app on top level. (F8, F10 and so on)
It's for displaying a programming tools windows in my global application, even if there is not selected elements (textfields, etc..)

Is there a way to trap key_event like sub mainform_keypress_event or anything else ?

I use the GameViewHelper library with the following code to capture a press of the F1 key to display a help file.

Private gvh As GameViewHelper

gvh.AddKeyListener("keylistener", MainForm)

Sub KeyListener_KeyPressed (KeyCode As String) As Boolean
    If KeyCode.Length = 2 And KeyCode.StartsWith("F1") Then
        Dim mf As ModalForm
        mf.Initialize(MainForm)
        mf.Show
    End If
    Return False
End Sub
