#402 Detaching a tab from a tabbed window diminishes size
Version:
NEdit 5.5RC1
Jul 23, 2004
Built on: Linux, 386, GNU C
Built at: Jul 24 2004, 13:45:55
With Motif: 2.1.30 [@(#)Motif Version 2.1.30]
Running Motif: 2.1 [unknown]
Server: The X.Org Foundation 60700000
Visual: 24-bit TrueColor (ID 0x23, Default)
Locale: C
Procedure:
1. Open a window with a few tabs.
2. From window open new window.
Result:
Second window takes its size from the proceding windows
text pane size, which is reduced due to the tabs.
Suggestions:
Either:
1. Tabs don't decrease text pane size... but instead
increases window size.
2. New window size is same as previous window size,
rather than from text pane size.
Opinion:
I'd prefer 1, but would concede to accept 2 - if necessary.
If others differ in opinion, then maybe an option to
control whether window size or text pane size is effected.

Cannot reproduce on Mac OS X. The new window has the same size as
the original window. In other words, the new window's text widget is
larger because it has no tabs.

I can confirm this with RC1 running on Sarge.

Which motif you are linking to? Please post the output of
nedit -V.

BTW, unless there're changes that I am not aware of, all new
windows should be created with the default settings. The
new window does not inherit anything AFAIK from the
invoking window.

I don't understand. I thought the linux binaries are static?
Anyway, I see the same thing on SuSE 9.1:

I made no assumption your were using the official binaries. In
any case, I could not reproduce the bug. The new windows
always respect my "Initial Window Size" setting - 40x80 in my
case.

Try the following:
0. Unset "Hide Tab Bar when only one Document is open"
setting
1. Open two tabs in one window.
2. Open a new window.
3. Open tab in new window.
Result: The second window (and its text panes) is smaller
than the first.
Do you see this?

On OS X from CVS, when I follow that procedure the new window is
*larger* than the original one. If I change the pref from always showing
the tab bar to hiding the tab bar when only one file is open
(checkbox goes from unchecked to checked) then the new window is
smaller. However, the windows don't keep getting smaller and smaller,
all subsequently opened windows are the same size.
This only happens during the session where I change the "Hide tab bar"
preferences setting. If I save defaults and restart then I don't see any
problem in future NEdit sessions. If that's true on other platforms then I
don't think we should let this bug hold up the release.

Doh, I meant to say *set* the setting. Whatever, you
obviously found the matching error making the window larger.
Indeed, I don't see this if the pref is already set if NEdit
is started. This should be postponed until after the release.

You can call it whatever you want, but it's not really a bug.
This behavior is by design - we chose not to resize the
window when we show/hide the toolbar components.
Similarly, if you disable/enable the statsline or i-search line of
one window, then open a new window from it - you get a
text pane of different size in the new window too. Though
you may argue.
This 'behavior' can be changed, if so desired.

TK, I think you're misunderstanding. The outer frame of the window
changes size, not just the text widget, so the two NEdit windows side by
side differ in size by the height of the tab bar. It looks like the height for
new windows (or some component of it) is calculated assuming the tab
bar is there (or not there) and then it isn't updated when the preference
changes. It's very minor but I think it's a bug.

OK. I'll need to take a look later.

I took a look again, and I still think, or confused, in the same
way.
The 2nd window has the larger size because it's text pane is
created with the size specified by the "Initial Window Size"
setting, plus the tab bar which is now always shown. The 1st
window has a smaller size because when the "Hide Tab bar.."
setting was disabled, or when more one tab is opened, it's
tab bar shows up and occupy the space taken earlier by the
text pane - which effectively shrinked the text pane(s).
As far as I can see, the 2nd window has the right size - it's
text pane's size respect the preference setting. So the first
idea I have in fixing this 'bug' will be to resize the first
window, whenever we toggle the toolbar components, in
order to maintain the size of the text pane(s). This may bring
us back to the shrinking-window bug we had earlier.

I see you point. The size is dominated by the text widget's,
not the window's size. I think what throw me off track here
is that the text widget is resized if a new tab is opened
(if the "Hide Tab Bar..." setting is set). That is of course
preferencable, so no point arguing it.
Wally, what do you think?

I concur. When I first opened the bug I thought it was
continuously diminishing... but I think I was just imagining
it (I've recently been ill).

I've found a way to get perpetually shrinking windows:
1. Open two files with tabs enabled but set the tab bar to hidden for
single documents.
2. Detach one tab -- the new window will be smaller than the original.
3. In the smaller window, open a second document.
4. Detach one tab -- the new window will be even smaller than the
second window.
You can keep doing this until the window is very very small. Basically, it
looks like the height of the new window is calculated based on the
presence of the tab bar in the original window. The new window only
has one document, however, so the tab bar doesn't show.
And no, the number of lines displayed in the text widget is not constant:
Window 1 without tab bar: 50 lines
Window 1 with tab bar: 48 lines
Window 2 without tab bar: 47 lines
Window 2 with tab bar: 45 lines
Window 3 without tab bar: 44 lines
Window 3 with tab bar: 42 lines
etc...
Actually, it looks like the off-by-one error (48 to 47, 45 to 44) is not
restricted to the case where you set the tab bar to hidden for single
documents. If I set the tab bar to always show I still get detached
windows that are one line shorter than the originals.

Should be fixed in CVS. The fix won't make it for RC2 but will be there
for 5.5 (or RC3 if such a thing proves necessary).

I think the scenario outlined by n8gray is what originally
caused my problem.

I have renamed the bug to more accurately reflect the actual problem.
