                         float labelSize)

Create a dialog allowing vector appearance to be changed.

Parameters:

gisFrame - GUI holding vector to be displayed.

pointFixed - Point size will remain fixed size with zooming if true.

lineWidth - Width of vector lines in pixels (can be fractional).

lineFixed - Line width will remain fixed size with zooming if true.

trans - Transparency scaled between 0 and 1 for polygon interiors.

boundColour - Boundary colour to use for polygons.

style - Style of rendinering. Either VectorMap.QUALITY or VectorMap.SPEED.

showLabels - Point lables shown if true.

labelBgColour - Label background colour.

labelFgColour - Lable foreground colour.

labelSize - Size of label text in font point units.
