on-change | Watch an object or array for changes | Runtime Evironment library

This question has been asked before but only regarding the cursor position as it seems..

I've implemented some kind of auto-load-on-change text editor based on QTextEdit. Problem is: when I apply the newly loaded text using

My CodenameOne app needs that some buttons have special icons. ScaleImageButton is the component that is suitable. The icons to be used are from the material icons repository, but some are modified, so the CN font is not suitable.

I created the icon images with the Flamingo tool that converts svg to java classes. It is cumbersome but it can be useful and practical, but at present time the resulting Java classes are not working on iOS.

It works on the CN simulator and Android although the button size is not exact: if state-changes reflect on some icon-changes, the layout would be rearranging and uneven.

On iOS, in addition to that, the drawing is huge or tiny in its viewport, depending of the button size that is assigned to the Flamingo image.

When I start my app in Android Studio, as usual, the emulator starts and the app openes.

But:

1. After I start the app, the run-logo doesn't change to the reload-logo.
2. When clicking the non-changed logo again, I can see "Install successfully finished in 1 s 451 ms." in "Run", but the app doesn't restart.
3. System.out and Log.e don't work

I tried:

1. Restarting Android Studio
2. Invalidate Caches / Restart
3. Rebuilding gradle
4. Wiping the emulator data
5. Reinstalling the app
6. Resetting the Run/Debug configurations

I found a question to another app starting problem, the answer was telling to delete the .AndroidStudio folder, but I could not find it (searched on my whole computer)

My theory: Android Studio is just starting my emulator and the app, but has no connection to it, as if I would start the app by myself.

Any help appreciated!

I am trying to build an app that allows a user to create multiple items and upload images for each item.

I am using Vux Uploader for uploading images like this

In React, onChange in the following code is regarded as an on input event handler, not on change, if I understand correctly:

Can someone help me with a issue when "shift + left click" selection on a filtered table and how it interacts with row deletions?

Steps:

1. Setup sample table
2. filter the table
3. register the selection changed event
4. shift + left click on two rows with discontinuous row number, selection change handler return all rows which included filtered out rows
5. right-click on the selections above and "delete sheet rows", filtered out rows were not being deleted.

Question:

• Should the filtered-out rows in between be selected?
• Should the filtered-out rows in between be deleted?

My code snippet:

I'm presenting a simple view controller. To follow MVC, I moved my programmatic view code into a separate UIView subclass. I followed the advice here of how to set up the custom view.

This works ok in iPhone. But, on iPad, the view controller is automatically presented with the new post-iOS 13 default modal style .pageSheet, which causes one of my buttons to be too wide. I looked into the view debugger and it's because the width constraint is set to self.bounds.width * 0.7, and self.bounds returns the full width of the iPad (1024 points) at the time the constraint is set, not the actual final view (which is only 704 points wide).

Three questions:

1. In general, am I setting up the custom view + view controller correctly? Or is there a best practice I'm not following?

2. How do I force an update to the constraints so that the view recognizes it's being presented in a .pageSheet modal mode on iPad, and automatically update the width of self.bounds? I tried self.view.setNeedsLayout() and self.view.layoutIfNeeded() but it didn't do anything.

3. Why is it that the Snooze button is laid out correctly on iPad, but not the Turn Off Alarm button... the Snooze button relies on constraints pinned to self.leadingAnchor and self.trailingAnchor. Why do those constraints correctly recognize the modal view they're being presented in, but self.bounds.width doesn't?
