One function for multiple pushbuttons in matlab -


i thinking of setting 1 function multiple pushbuttons, same thing, has different defining value. when 1 pushbutton activated not mixed other pushbutton of same function

see the documentation callbacks. callbacks accept 2 input arguments default: handle of object invoked function , structure of event data object, may or may not empty. can use string or tag properties of pushbutton control behavior of gui based on button pressed using single callback function. consider following example:

function testgui handles.mainwindow = figure();  handles.mytextbox = uicontrol( ...     'style', 'edit', ...     'units', 'normalized', ...     'position', [0.15 0.80 .70 .10], ...     'string', 'no button has been pressed' ...     ); handles.button(1) = uicontrol( ...     'style', 'pushbutton', ...     'units', 'normalized', ...     'position', [0.05 0.05 .30 .70], ...     'string', 'button1', ...     'callback', {@mybuttonpress,handles} ...     ); handles.button(2) = uicontrol( ...     'style', 'pushbutton', ...     'units', 'normalized', ...     'position', [0.35 0.05 .30 .70], ...     'string', 'button2', ...     'callback', {@mybuttonpress,handles} ...     ); handles.button(3) = uicontrol( ...     'style', 'pushbutton', ...     'units', 'normalized', ...     'position', [0.65 0.05 .30 .70], ...     'string', 'button3', ...     'callback', {@mybuttonpress,handles} ...     ); end  function mybuttonpress(src, ~, handles) switch src.string     case 'button1'         handles.mytextbox.string = 'button 1 has been pressed';     case 'button2'         handles.mytextbox.string = 'button 2 has been pressed';     case 'button3'         handles.mytextbox.string = 'button 3 has been pressed';     otherwise         % strange happened end end

note requires matlab r2014b or newer in order use dot notation accessing object properties. see this blog post more information.

i have defined aidl file interface imyfeature { void dotask(class clazz); } but need pass class object process. possible in android? if so, how? i tried: interface imyfeature { serializable class; void dotask(class clazz); } but doesn’t work. aidl in android supports custom class implement parcelable interface. in case want send class object not possible. can send class canonical name , retrieve in service. for example have aidl file interface imyfeature { void dotask(string classname); } then call : binder.dotask(myclass.class.getcanonicalname()); and in service binder stub implementation : private final imyfeature mbinder = new imyfeature.stub() { public void dotask(string classname) { try { class<?> clazz = class.forname(classname); constructor<?> ctor = clazz.getconstructor((class[]) null); object object = ctor.newinstance(); ...
