aggregatedisplay.Item

You don't need to inherit from this - it is mainly to document what you have to implement.

Draw(self, dc, width, height, selected)

Draw yourself into the available space. 0,0 will be your top left.

Note that the width may be larger than the DataSource.GetItemSize method returned because unused space is spread amongst the items. It will never be smaller than what was returned. You should set the clipping region if necessary.

The main display code needs to know the bounding box for each item so that it can tell when an item has been clicked on, as opposed to the white space surrounding an item. By default it clears the bounding box and looks at what area you draw on in this function. If you return None, then that is what happens.

Instead you may also return a 4 item tuple of (minx, miny, maxx, maxy) and that will be used.

Parameters:

dc - The device context to draw into
width - maximum space to use
height - maximum space to use
selected - if the item is currently selected
