How to set the property for jslider

%This is what I have declare in the OpeningFcn

[class,handles.jSlider_brightness] = javacomponent(javax.swing.JSlider,[440,340,350,40]); set(class,'PaintTicks',1,'SnapToTicks',0,'MajorTickSpacing',1,'PaintLabels',1,'PaintTrack',1,'maximum',1,'minimum',-1,'value',0); set(handles.jSlider_brightness,... 'StateChangedCallback',{@jSlider_brightness_Callback, handles});

%%I have a callback function as below :

_________________________________________________________

function jSlider_brightness_Callback(hObject, eventdata, src) global hLoadFile; handles = guidata(src); listIdx = get(handles.popupmenu_colormap,'Value'); handles.beta = get(handles.jSlider_brightness,'value'); handles.new_colormap_P = brighten(hLoadFile.handles.colormap.all_colormap{listIdx},handles.beta); colormap(handles.axes_fig,handles.new_colormap_P); % Update structure guidata(hObject,handles);

____________________________________________________________

this gui is to update the brightness of the colormap when sliding the slider but it only allow me to show the result with -1,0,. Anyone know how to solve this problem?

Thank you in advance!!!
