[Gambas-user] Resize event...

[Stephen Bungay]

   Well, after much consultation with Benoit I finally understand what 
is going on and how to get around the problem.

   For the benefit of anyone else who has been reading this thread, 
Doraino and I were talking about instantiating a form inside a container 
on another form and resizing that embedded form when the parent is resized.

   In a nutshell the solution is to reference the instantiated form by 
it's handle reference, created at the time of it being instantiated, and 
NOT by its' name.

For example, consider an application that has three form classes, 
FormMain, FormX, and FormY. Form Main will contain a tabstrip and inside 
that tabstrip we want to instantiate FormX on tabstrip index 0 and FormY 
on tabstrip index 1. When we resize FormMain we want the embedded forms 
in their tabs to resize appropriately. Our FormMain Class logic might 
look like this;

' Gambas class file
Private mFormInitialized as Boolean
Private mhFormX As FormX
Private mhFormY AS FormY

Public Sub Form_Open()
   InitializeControls
End


Private Sub InitializeControls()
   TabStrip1.Index = 0
   mhFormX = New FormX(TabStrip1)

   TabStrip1.Index = 1
   mhFormY = New FormY(TabStrip1)

   TabStrip1.Index = 0

   mFormInitialized = True
End


Public Sub Form_Resize()
   With TabStrip1
        .Width = .Parent.width - 10
        .Height = .Parent.height - 20
        mhFormX.Resize(TabStrip1.Width - 10, Tabstrip1.Height - 10)
        mhFormY.Resize(TabStrip1.Width - 10, Tabstrip1.Height - 10)
   End With
End

   The resize events in the forms referenced by mhFormX and mhFormY will 
now fire as expected, the embedded forms resize events will now fire as 
expected.
