Toggling hide/show gaps corrupt sequence display

[westram]

• reproduce:
  • save properties with uncompressed display (showing gaps)
  • restart editor
  • set cursor to a "far-right" column (or behind alignment)
  • switch to compressed display (hiding gaps)
  • ⇒ sequences disappear (and it seems impossible to make them re-appear)

• related : fixed with #509
  • save props with compressed display + restart editor
  • value displayed in EDIT4/Properties/Edit Options/Seq.Compression is wrong (Show all gaps is selected), but display is correct
  • see also [8354]

I am unable to reproduce this .

What I dit:

• Open arb_ntree
• Open arb_edit4
• Choose 'show all gaps' in editor options
• click Properties → save properties → save Properties
• restart arb_edit4
• choose 'hide all gaps' in editor options
• sequences are still there, gaps are missing.

I can reproduce something. At least, playing with the show gaps settings pretty quickly messes up the editor entirely. There is something rotten in the editor though, doing the same in motif doesn't cause display mess-up but does result in a motif warning:

Warning: 
    Name: scroll_bar_horizontal
    Class: XmScrollBar
    The specified scrollbar value is greater than the maximum
    scrollbar value minus the scrollbar slider size.

This is probably at least one thing that makes GTK puke.

I'm not getting anywhere. The editor's internals are simply too confusing. Ralf, can you maybe have a look at this? Right now I'm tempted to claim that I'd be faster writing EDIT5 than fixing this issue (i.e. many months).

Not atm, I've already spend months with that issue w/o being able to fix that properly.

Ok, deferring the issue for now.

Ok, seems to be mostly fixed now.

I had to change the sequence in which ED4_window updates scrollbar settings in trunk: r10883

The rest is in log:branches/gtk_only@10884-10889

The is mostly fixed. The display isn't updated correctly yet.

Ralf: could you confirm that it's fixed?

Yes - it's fixed - great!
