javafx - JavaFX8: How to tell when the mouse hovers over the header portion of a table column? -

-

i'd display legend in popover control when user hovers mouse on 'header' portion of particular tablecolumn. possible? how? if not possible, welcome suggestions other approaches.

you can install tooltip on node, trick node in mouse neighbourhood of column header. there way using node.lookup it's not ideal since may change.

i think simplest way set own graphic header instead of default text , add tooltip that.

    tablecolumn<data,string> tc1 = new tablecolumn<>();     tablecolumn<data,string> tc2 = new tablecolumn<>();     tooltip t1 = new tooltip("column one");     tooltip t2 = new tooltip("column two");     tc1.setgraphic(new text("col 1"));     tc2.setgraphic(new label("col 2"));     tooltip.install(tc1.getgraphic(), t1);     tooltip.install(tc2.getgraphic(), t2);

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...
