Description

Implementing a grid with CAknGrid as in the FileList example application in the SDK causes incorrect behavior when the cell in focus is changed a number of times. The last 2 cells (on the right-hand side of the screen) are not redrawn properly and become white gradually (because of being highlighted a number of times).

How to reproduce

  1. Launch the FileList example application in portrait mode.
  2. Switch to landscape mode.
  3. Change the cell in focus a number of times.

Some of the cells are not redrawn properly.

Solution

The issue can be solved by calling CFormattedCellListBoxData::SetSkinStyle()in its SizeChanged() method. Normally lists and grids have code in their SizeChanged() implementation which calls SetSkinStyle():

void CGridExContainer::SizeChanged()
{
...
iGrid->ItemDrawer()->FormattedCellData()->SetSkinStyle(&KAknsIIDQsnBgAreaMain,
Rect());
...
}
