You indent the lines with 2 spaces, while the coding style specifies 4.
The coding style is documented in detail here: http://techbase.kde.org/Policies/Kdelibs_Coding_Style

The layout isn't done until items are actually inserted into the model, so until that happens m_columns will be 0.

What exactly is it doing, is unclear to me as I couldn't find some way to set the flow from the applet config and see the effect. Please hint on this.

The flow can only be configured in the config dialog when the applet is used as a containment, but basically it controls how the icons are laid out in the view, like this: 

LeftToRight:
[1][2][3]
[4][5][6]
[7][8][9]

RightToLeft:
[3][2][1]
[6][5][4]
[9][8][7]

TopToBottom:
[1][4][7]
[2][5][8]
[3][6][9]
