Using Menus, Toolbars and Statusbars

Default Menubar Characteristics

By default, a menubar will have the following characteristics:

  • It will be the first horizontal bar (peBarPosition = xtpBarTop)
  • It cannot be moved and docked (pbEnableDocking = False, pbGripper = False)
  • It stretches to take the full panel width, and that space cannot be shared with other toolbars (peStretched = stStretch)
  • It cannot be closed (pbCloseable = False)
  • It cannot be edited (pbCustomizable = False)
  • When needed, it wraps to the next line (pbHideWrap = False)

The Menubar Creation Process

When the commandbar system is created, the message CreateComInstance is sent to the cCJMenuBar object. This method is used to:

  1. Create the COM menubar.
  2. Send the appropriate COM messages.
  3. Send the OnCreate event. This can be used by developers to customize the creation process.
  4. Create all child menu objects by sending CreateComInstance to all child objects.

Once the COM object is created, it remains statically bound to its cCJMenuBar proxy object.
