gwt2 - PropertyChangeSupport in GWT -

-

in gwt application developed module uses java.beans.propertychangesupport. have started using module , getting the import java.beans cannot resolved error when run. application runs well. why getting compiler error in gwt dev mode window? ideas?

00:17:33.079  [error] errors in 'file:/d:/workspace/app/src/main/java/com/abc/def/client/extract/pojos/clientdata.java' 00:17:33.079  [error] line 3: import java.beans cannot resolved 00:17:33.079  [error] line 4: import java.beans cannot resolved 00:17:33.079  [error] line 11: propertychangesupport cannot resolved type 00:17:33.079  [error] line 14: propertychangesupport cannot resolved type 00:17:33.079  [error] line 14: propertychangesupport cannot resolved type 00:17:33.079  [error] line 17: propertychangelistener cannot resolved type 00:17:33.079  [error] line 18: propertychangesupport cannot resolved type 00:17:33.079  [error] line 21: propertychangelistener cannot resolved type 00:17:33.079  [error] line 22: propertychangesupport cannot resolved type 00:17:33.079  [error] line 25: propertychangelistener cannot resolved type 00:17:33.079  [error] line 26: propertychangesupport cannot resolved type 00:17:33.079  [error] line 30: propertychangelistener cannot resolved type 00:17:33.079  [error] line 31: propertychangesupport cannot resolved type 00:17:33.079  [error] line 36: propertychangelistener cannot resolved type 00:17:33.079  [error] line 36: propertychangesupport cannot resolved type

autobeans mentioned bobv great new feature of gwt, refactoring of existing code required in order use them. if application uses propertychangesupport, gwtx project provides gwt emulation of java.beans.propertychange* classes.

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....
