[Gambas-user] How to soft depend on gambas3-gb-qt4-webkit

[Geoffrey De Belie]

I get "invalid identifier WebView" when trying to run the software without gambas3-gb-qt4-webkit:

in the HelpBrowser class:
Private Sub GetView() As WebView
  
  Try Return tabBrowser[tabBrowser.Index].Children[0]
  
End

in the Main class meanwhile:
Public Sub OpenHelp()
    
    Component.Load("gb.gui.qt.webkit")
    HelpBrowser.Show()
    Catch
        Desktop.Open("./help/index.html")
    
End

Kind regards,
Geoffrey De Belie
