Field Detail

fbContDraw

private Bool_t fbContDraw

If true, draw corresponding value as label on working pad

private Bool_t fbHasConnector

Switch connectionline between marker and label on or off.

private Bool_t fbHasLabel

Switch marker label on or off.

private Bool_t fbIsPainted

Flag to prevent Paint() method to redraw marker views after UnDraw.
Problem with Paint() called from ROOT event loop.

private Bool_t fbVisible

Visibility of this marker on pad. For marker array in editor

be used in Paint() which is called on TPad::Update automatically for
all TObjects appended to the pad.
