path: root/dist/changes-4.3.2

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.

      aliased.

- QSqlTableModel
    * [170783] Fixed a bug that caused empty rows to be displayed in a
      QTableView when a new model was set on the view. This was caused by

      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.
