UIFigure button callbacks not working when cursor over uiimage (R2020b)

2 views (last 30 days)
I really just need WindowButtonMotionFunction to work, but it doesn't:
classdef SIMineyCricket < matlab.apps.AppBase
% Properties that correspond to app components
properties (Access = public)
UIFigure matlab.ui.Figure
SwitchLabel matlab.ui.control.Label
Switch matlab.ui.control.Switch
cricketImage matlab.ui.control.Image
refPinImage matlab.ui.control.Image
DataStreamAxes matlab.ui.control.UIAxes
end
% Callbacks that handle component events
methods (Access = private)
% Code that executes after component creation
function startupFcn(app)
app.UIFigure.UserData = struct('clickedObject',{[]},'lastPosition',{[]});
end
% Window button motion function: UIFigure
function UIFigureWindowButtonMotion(app, event)
disp(randi(10));
if ~isempty(app.UIFigure.UserData.clickedObject)
app.UIFigure.UserData.clickedObject.Position = [app.UIFigure.CurrentPoint,app.UIFigure.UserData.clickedObject.Position(3:4)];
end
end
% Image clicked function: refPinImage
function refPinImageClicked(app, event)
disp('clicked pin')
if ~isempty(app.UIFigure.UserData.clickedObject)
%drop object
app.UIFigure.UserData.clickedObject = [];
else
%pick up object
app.UIFigure.UserData.clickedObject = event.Source;
end
end
% Window button down function: UIFigure
function UIFigureWindowButtonDown(app, event)
display(app.UIFigure.CurrentPoint);
end
end
% Component initialization
methods (Access = private)
% Create UIFigure and components
function createComponents(app)
% Create UIFigure and hide until all components are created
app.UIFigure = uifigure('Visible', 'off');
app.UIFigure.Position = [100 100 679 481];
app.UIFigure.Name = 'MATLAB App';
app.UIFigure.WindowButtonDownFcn = createCallbackFcn(app, @UIFigureWindowButtonDown, true);
app.UIFigure.WindowButtonMotionFcn = createCallbackFcn(app, @UIFigureWindowButtonMotion, true);
% Create SwitchLabel
app.SwitchLabel = uilabel(app.UIFigure);
app.SwitchLabel.HorizontalAlignment = 'center';
app.SwitchLabel.Position = [605 190 42 22];
app.SwitchLabel.Text = 'Switch';
% Create Switch
app.Switch = uiswitch(app.UIFigure, 'slider');
app.Switch.Position = [603 227 45 20];
% Create cricketImage
app.cricketImage = uiimage(app.UIFigure);
app.cricketImage.Position = [11 15 341 222];
app.cricketImage.ImageSource = 'cricket.jpg';
% Create refPinImage
app.refPinImage = uiimage(app.UIFigure);
app.refPinImage.ImageClickedFcn = createCallbackFcn(app, @refPinImageClicked, true);
app.refPinImage.Position = [351 161 72 76];
app.refPinImage.ImageSource = 'pin.png';
% Create DataStreamAxes
app.DataStreamAxes = uiaxes(app.UIFigure);
title(app.DataStreamAxes, 'Data Stream')
xlabel(app.DataStreamAxes, 'time (s)')
ylabel(app.DataStreamAxes, 'mV')
app.DataStreamAxes.ColorOrder = [0 0.447 0.741;0.85 0.325 0.098;0.929 0.694 0.125;0.494 0.184 0.556;0.466 0.674 0.188;0.301 0.745 0.933;0.635 0.078 0.184];
app.DataStreamAxes.TickDir = 'out';
app.DataStreamAxes.Tag = 'DataStream';
app.DataStreamAxes.Position = [11 246 659 226];
% Show the figure after all components are created
app.UIFigure.Visible = 'on';
end
end
% App creation and deletion
methods (Access = public)
% Construct app
function app = SIMineyCricket
% Create UIFigure and components
createComponents(app)
% Register the app with App Designer
registerApp(app, app.UIFigure)
% Execute the startup function
runStartupFcn(app, @startupFcn)
if nargout == 0
clear app
end
end
% Code that executes before app deletion
function delete(app)
% Delete UIFigure when app is deleted
delete(app.UIFigure)
end
end
end
