java - Synchronized JList and JComboBox? -

synchronized jlist , jcombobox?

hello,

in java swing, what's best way jlist , jcombobox synchronized in terms of data, i.e., have same list of items @ given point of time? basically, if add items (or remove items from) one, other should reflect change automatically. i've tried doing following, doesn't seem work:

jlist list = new jlist(); jcombobox combobox = new jcombobox(); defaultlistmodel listmodel = new defaultlistmodel(); // add items listmodel... list.setmodel(listmodel); combobox.setmodel(new defaultcomboboxmodel(listmodel.toarray()));

you're creating 2 models in code. when construct new defaultcomboboxmodel passing in listmodel contents constructing second model starts same contents first. won't update same. want 2 components share model. in other words...

jlist list = new jlist(); jcombobox combobox = new jcombobox(); defaultcomboboxmodel listmodel = new defaultcomboboxmodel(); // add items listmodel... list.setmodel(listmodel); combobox.setmodel(listmodel);

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,...

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
