           Summary: Slow resizing because screen updates after each
                    row/column
           Product: kspread
           Version: 1.5.2
          Platform: Debian testing
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: kspread-bugs-null kde org
        ReportedBy: holgerschurig gmx de


Version:           1.5.2 (using KDE KDE 3.5.4)
Installed from:    Debian testing/unstable Packages
OS:                Linux

I have a simple spreadsheet with 200 rows and ~15 columns. Now When I select all 200 rows and click on the leftmost bar (the one with the numbers) to resize the height, then kspread does resize all 200 rows.

Good.

What is not good is that it updates the screen after each resize operation, about 200 times. That very slow, on my computer with 1 GHz and a normal 2D graphics card about 40 seconds.

Suggestion: use setUpdatesEnabled(False)/setUpdatesEnabled(True).
