Error using mlapptools.getWebElements #25

Regarding the first issue, as the error says - more time needs to pass between the creation of the UIFigure and running
Regarding the 2nd issue - when exactly does it happen? When you run the code, or after you close a |

Thank you for your answer @Dev-iL . To answer your remarks :
I tested what you say but the issue n°2 is now showing 100% of the time...
It happens just after starting the interface (3 -4 seconds of delay). Actually, the I give you my code (I would prefer in private) but you will have many parts missing... Thanks |

@thiblab Please try to create a new App with just the minimum code required to reproduce the issue, then post the code of the App here. Did you try saving the code of the App in a regular |
|
The issue 2 seems indeed appear only with App Designer. So in which conditions I have to use mlappTools ? When using the code of App Designer but not using App Designer itself ? |
|
Yes, I would say that this is a sound course of action (at least that's how I always use it, because I used to have various problem running App Designer, so I ended up creating UIFigures completely programmatically)... You see, the App Designer itself is a uifigure (and hence, a "browser window"), so there must be some issues when we try making MATLAB have two browser windows communicating with each other. |

Sorry, I replied too fast. Below is a simple code that I am running as The behavior is actually strange : Sometimes it works, and when it works both |

I can reproduce your problem. If your use-case permits it, I suggest you only take the code that creates components (and callbacks if there are any), then apply your customizations at the end. %% Create UIFigure and add components:
app = struct(); % < This is just to keep the same structure for the rest of the code.
% Create UIFigure
app.UIFigure = uifigure;
app.UIFigure.Position = [100 100 640 480];
app.UIFigure.Name = 'UI Figure';
% Create TabGroup
app.TabGroup = uitabgroup(app.UIFigure);
app.TabGroup.Position = [100 82 325 280];
% Create Tab
app.Tab = uitab(app.TabGroup);
app.Tab.Title = 'Tab';
% Create Tab2
app.Tab2 = uitab(app.TabGroup);
app.Tab2.Title = 'Tab2';
%% Customize using mlapptools:
pause(5); % might need to be longer, depending on your computer.
[win, widgetID] = mlapptools.getWebElements(app.TabGroup);
...In conclusion - until we find a way to better way to avoid these crashes, you should only use |

Thanks for your answer, but actually it has fixed the issue. I can put Actually, I want to be able to personalize the Tab Group (cf screenshot) (Size of click panel, Selected / Unselected Color, Font, Font Size, Underlying...). Am I able to do this with mlappTools ?

I didn't try doing anything like that myself, but I expect that it is possible, yes. I would also advise you to use the documented ways to edit components as much as possible, and only when you reach their limit, switch to |
|
Actually, the documented way doesn't offer any possibility to customize the Today I tried the 'manual' way to retrieve tags and ID and the issue is the same, and appear only with the |
|
If you have to use methods (Access = private)
% Code that executes after component creation
function startupFcn(app)
start(timer('TimerFcn', @(x,y)app.customizeElements(), 'StartDelay', 10));
end
function customizeElements(app)
[hWin, widgetID] = mlapptools.getWebElements(app.TabGroup);
[childIDs] = mlapptools.getChildNodeIDs(hWin, widgetID);
mlapptools.setStyle(hWin, 'background', 'transparent', childIDs(2));
[childIDs] = mlapptools.getChildNodeIDs(hWin, childIDs(2));
mlapptools.setStyle(hWin, 'background', 'black', childIDs(4));
end
endNote that it will only crash if the timer delay is too short. |
Summary
I am having troubles when using the following function :
[win, widgetID] = mlapptools.getWebElements(app.TabGroup);The issue is quite random. I can have issue 1 or issue 2, you can find below. I don't understand any of them. About issue 2 I looked what has been said about it on Matlab forum, like upgrade driver etc.. But I did it, tried the function on several computer and I still have it.
