Basically situations can be created where the formulas
are not centered, out of view, and scroll bars not shown.
* Open Open Office Math
* In the command Window type "x+y"
* Wait 2 second till formula view is updated
* select the "+y" with mouse and Copy (Ctrl+c)
* Now paste +y (Ctrl+v) repeatedly till you get about
one line of text in the command windows as follows
"
a+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y+y
"
* Wait 2 seconds till formula display is updated
* When updated, on a 1280x1024 resolution screen, and a maximized
application window, the end of formula
display goes out of view, as formula has actually started
from the beginning. On larger resolution monitors you might need
longer texts to go out of view.
workaround
* zoom out, and zoom in, and a refresh is forced.
The formula display is centered, and scroll bars appropriately displayed
(A refresh also happens during an autosave)
This effect can be played with in many ways
* create a really long equation
* zoom in zoom out to center the formula view
* now select all (ctrl-A) replace with a small equation
* It will not be visible on screen as it might be completely to the left
and outside the formula view.
same thing can be done using multiple "x+y newline" to get the formula
out of display vertically.
The philosophy seems to be to hold the formula in the
formula display stationary, maybe for aesthetics, or maybe for future
grahical equation editing. However in doing so, large formulas
can go out of view.
Desired : When some change is made in the formula command window,
* Check where the new cursor point is still visible in the formula view
If formula-cursor-point has gone out of view then
* center formula in the formula view
* set the hscroll and vscroll so that the formula-cursor-point is
within a smaller rectangle in the view.
* Enable/disable the scroll bars appropriately.
* redraw formula view
Found in Openoffice 2.1 (release) winXP
