Summary:
In apps Listbox scrollbars appearance and placement can be wrong and
is inconsistent
Requests: 8
Category:
REALbasic / Framework / User Interface / Controls / ListBox
Severity:
Incorrect Functionality
Description
This is BOTH incorrect functionality AND cosmetic
Tests show it affects OSX, Classic, Win2K ... I assume Win XP but I
can't test it.
With Autohide = false (I did not try with true) listbox scrollbar
placement is wrong can be wrong and the order of operations affect
appearence...
Note: I have since verified at least some of these issues occur with
Autohide = True
The end cap is where the horizontal and vertical scrollbars come
together is never drawn on 10.4.7 or 10.4.8. When both are present
sometimes a white square (OSX) is left where the end cap should be,
sometimes the vertical scrollbar extents the whole height even when a
horizontal scrollbar is present.
And sometimes the horizontal scrollbar is not drawn at all leaving a
"hole" where the window shows through
In R4B5 in classic the listbox does draw the end cap ... but in some
cases outside the listbox bounds (see tiff)
The same code run from RB 5.5 always draws the scrollbars correctly
but not the end cap on 10.4.7
See Rb55Listbox.tiff. That was not the case back when I was using 5.5
in a lower OSX version. In classic for RB 5.5 everything is correct
For RB2006R4b5 when the app is run in CLASSIC, the end cap is always
drawn but sometimes totally outside the listbox bounds
On Win2K The same problems as on OSX are seen.
also, the new IDE sets the autohidescrollbars of v5.5 listboxes to
true when they should remain false.
IDE Version
RB2006R3 and R4
Steps to Reproduce
Run the attached project
Top unpopulated listbox is missing the horizontal scrollbar leaving a
"hole" and vertical scrollbar extends the full height
Middle populated list box shows correct horizontal scrollbar but
vertical scrollbar extends the full height... and on classic the end
cap is still drawn below below the verticak scroolbar ... but out
side the listbox bounds!
Bottom listbox shows both scrollbars correctly but in missing the end
cap at the intersection. Push the buttons to activate both scrollbars,
See enclosed project and Tiffs
In short it seems that on 10.4.7 (amd Win2K) the end cap is simply
not drawing though code is in place to draw it at least on PEF Mac
Apps as it is drawn in Classic . Also the logic for positioning/
drawing scrollbars is buggy, at least for AutoHide = false... Though
I would not be surprised if it is also an issue in some cases for
AutoHide = True
Note: Confirmed some of these issue exist for AutoHde = True
Workaround
none. the default for autohidescrollbars should be false, and the IDE
should not set listboxes brought in from v5.5 to true. Scrolbar
drawing and updating when autohidescollbars is false does not work
and needs fixed.
the "hole" goes away if you set ColumnCount to match the number of
columns specified in ColumnWidths. drawing is still wrong (the
scrollbar goes all the way across instead of leaving an endcap), but
at least there's a usable scrollbar.
Report State Change Request
Could this at least get reviewed so it has chance of getting fixed?
Listbox are important!
