flex - spark List with ItemRenderer click function not working -

-

i having issue itemrenderer, using spark list. code following:

i have list:

<s:list      id="productsetlist"      dataprovider="{ model.productsets }"      change="model.selectset( productsetlist )"      height="100%" width="100%"     bordervisible="false"      itemrenderer="sidebaritemrenderer" top="20" left="15"> </s:list>

and itemrenderer is:

<s:itemrenderer      xmlns:fx="http://ns.adobe.com/mxml/2009"      xmlns:s="library://ns.adobe.com/flex/spark"      xmlns:mx="library://ns.adobe.com/flex/halo"      width="160" height="175" autodrawbackground="false" buttonmode="true" usehandcursor="true"     click="click(event)" cacheasbitmap="true"     >       <fx:script>         <![cdata[             import com.png.vm.model.vos.productset;              protected function click(event:mouseevent):void             {                 trace('arthur');             }          ]]>     </fx:script>      <s:bitmapimage source="{productset(data).image}" width="160" height="175"/>  </s:itemrenderer>

the thing is, if scroll list, , click on item, not trace 'arthur' ! why ? must trace time clicks in list!

edit: if remove change="model.selectset( productsetlist )" in list, works!! cannot remove that, suggestions ? how can switch function?

trace works when debugging/using debugging version of flash player. make sure using that. if want pop-up message use alert.show("message")

for more information trace() check out: http://livedocs.adobe.com/flex/3/html/help.html?content=logging_08.html

and alert.show(): http://help.adobe.com/en_us/as2lcr/flash_10.0/help.html?content=00001965.html

if running debug player. try originating click event embedded <s:group> way whatever add in here beyond bitmap still trigger click event.

something like:

<s:group width="100%" height="100%" click="click(event)" >     <s:bitmapimage source="{productset(data).image}" width="160" height="175"/> </s:group>

i've had click events work me inside of itemrenderers before

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....
