Qt 4.3.2 is a bug-fix release. It maintains both forward and backward

compatibility (source and binary) with Qt 4.3.0 and Qt 4.3.1.

The Qt version 4.3 series is binary compatible with the 4.2.x, 4.1.x and

4.0.x series. Applications compiled for Qt 4.0, 4.1 or 4.2 will continue to

run with Qt 4.3.

      results for justified text.

    * Prevented a number of possible crashes that could occur when there are

      pending changes.

    * [177165] Fixed a bug that caused minimum column widths to become

      independent of the width of the text in the header.
