spring mvc - How to post data and redirect to another page using GWT? -

-

when press button post data server , there redirect page. used requestbuilder waiting response, , of course it. , nothing happens, same page stays. see requestbuidler shouldn't used here... should use post data , able redirect?

in spring

@requestmapping(method=requestmethod.post, value="/ddd") public modelandview processorder(@requestbody string orderinstring, httpsession session) throws exception{     ...     return new modelandview(new redirectview("abc"));  }

in gwt

public void postdata(final string data, final string url) {     requestbuilder builder = new requestbuilder(requestbuilder.post, url);     try {         builder.sendrequest(data, new requestcallback() {             public void onerror(request request, throwable exception) {                 ...             }              public void onresponsereceived(request request,                     response response) {                 if (200 == response.getstatuscode()) {                     ..                 } else {                     ..                 }             }         });     } catch (requestexception e) {         ...     }     return; } 

    formpanel form = new formpanel("_self");     form.setmethod(formpanel.method_get);      hidden params0 = new hidden("param1", "value1");     hidden params1 = new hidden("param1", "value2");     hidden params2 = new hidden("param2", "value3");      flowpanel panel = new flowpanel();     panel.add(params0);     panel.add(params1);     panel.add(params2);      form.add(panel);      form.setaction(gwt.getmodulebaseurl() + "../myservlet");     rootpanel.get().add(form);     form.submit();

thats it. code adds formpanel , sends form.

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....
