Standalone windows behave differently from other CS-Studio windows

[claudio-rosati]

Here the original problem from my integrators:

The problem is that standalone window will not have the zoom bar any more. But zoom is used quite a lot to make the graphics fill the whole window. Is it possible to enable zoom on those windows too?

Inside CS-Studio (maybe on Phoebus it's different) we have the following 3 window's possibilities ("Replace" a part) with their pros, cons, and problems:

• New Workbench Window
  • It opens a new window whose existence, location and size are remembered;
  • The ZOOM selector is available and its value is remembered;
  • The window needs extra space for the toolbar, tabs bar and status bar;
  • Other tabs can be added to the window.
  • Right-click opens the contextual menu.
• New Tab
  • It opens a new tab that can be detached and moved in a different screen (and/or workbench);
  • Existence, oosition, size are remembered (on MacOS X position on a different screen is not restored);
  • The ZOOM selector is available and its value is remembered;
  • The window needs extra space for the tabs bar;
  • Other tabs can be added to the window.
  • Right-click opens the contextual menu.
• Standalone Window
  • Opens a new window only containing the OPI, without any extra space used;
  • Position is remembered (also on different screens), but not size and existence;
  • No ZOOM control, but zoom can be set via CTRL/CMD + WHEEL. Zoom is not remembered.
  • Right-click doesn't open the contextual menu.

I suggest the following enhancements for the Standalone Window mode:

• Open a contextual menu with right-click (this probably is of very low priority if the Phoebus integration will allow to get rid of the CS-Studio version of DB soon, otherwise not);
• Add a "Zoom…" entry in the contextual menu to open a dialog containing the ZOOM control (this could be always an option, standalone or not);
• Save and restore the window's size and zoom value;
• Save and restore its existence.

'Standalone' now is a detached RCP part with context, zoom, perspective,
