Reimplement windows with DIVs

[Joonas Lehtinen]

Trying to support "real" windows is just plain silly, because:

• It is guaranteed to be unrealiable
  • Many of us have popups blocked
  • Or "open windows to new tab" selected
  • There are countless number of browser security related bugs in different browsers
  • Sometimes new windows are opened behind other windows. There is nothing we could do about it (reliable)
• MDI is just what people want
  • People use browsers to get everything on one page
• DIVs are lightweight
• Window close button should work - it is easy to do in div-based impl, but hard with real browser windows

My conclusions:

• Do not try to support real browser windows in AJAX
• Do not try to support real frames in AJAX

What could we do in HTML-mode? Either

• Nothing, current implementation works. Usually.
  • HTML mode rendering must be reworked anyhow to get everything working reliably..
• Reimplement windows with IFRAMES

Now "real" windows work, as well as they will...

Windowing

createWindow(

z-index

• Z-Index regions
  • 0-11999 Free main window
  • 12000-19999 Windows: 100 indexes / window
    • 12000 Window shadow
    • 12001 Iframe (blocker)
    • 12002 Window border and content divs (content overflow: auto|hidden)
    • 12050- Reserved
  • 20000 Modality curtain
  • 20001 Modal window
  • 30000 Popuping thingys (descriptions, contextual menus, ...),

Modality

• What about dual modals? Not supported.
• Server side api needed for window

Native window support

• Native windows are kept, but not as default

Frames

• Div frames

Borders

• BORDER_DEFAULT "Div" window with controls (titlebar, move, close, resize,...)
• BORDER_MINIMAL == BORDER_DEFAULT
• BORDER_NONE "Div" window with no titlebar, small border (closable, resize, move?)
• BORDER_NATIVE Browser native windows as well as we can

Events

Add listeners, getters and setters for:

• Resize
• Close
• Position
• Positioning base
• Z-index changes listener

Both server and javascript sides

Postponed 4.0.1.

[Jani Laakso]

Decided to push release date for rc two days ahead in order to try getting this ticket into rc too.

[Matti Tahvonen]

in [] a first commit. Lots of bugs still though.

Joonas, one request for you:Could you make repaintAll send uidl all windows, unless they have "native" style set.

[Matti Tahvonen]

changeset for last command was [780]

[Joonas Lehtinen]

Matti, added [781] to repaint all non-native windows on repaintAll.

[Matti Tahvonen]

quite a lot of improvements done between [781]-[806]. Default (div) and "native" style windows now work side by side.

Known issues left atm:

• API (at least closing window from client side)
• DIV windows with external URI or resource (via window.open(blaah, ...) calls) don't work (need yet another iframe)
• bit rude window colors

[Matti Tahvonen]

Status at [848] :

• themes ok (Base, Corporate)
• closing mechanism on both server and client implemented
• at least URL opens work and most likely others too
• fixed first bugs

I'd consider that DIV windows are already more stable than old "native". I'm closing this now. Remaining issues can be put (like feeding x,y coordinates to server) to separate tickets.
