I am making a plugin to CkEditor. It's a widget
which is mostly just a h1 with a css class.
That is working fine, but now I need to listen to all keyboard presses when the cursor is in my plugin, because my widget need special actions on some keyboard input.
But how do I listen to keyboard events, when the cursor is in my widget?
I can use
editor.on('key', function(event) {
console.log("Got key up");
})
But then I get all keyboard events in the entire editor. My widget only need/want input if the cursor is within the widget

Flutter desktop:
I'm successfully using the RawKeyboardListener widget to use physical arrow keys and control the listview (selects items up and down). The scaffold is wrapped in it.
The problem is the listview widget itself has built in default keyboard actions on the arrow keys that also scroll up and down. These actions that are randomly triggered in the listview when they are pressed along with my custom actions handled by the RawKeyboardListener.
Does anyone know how to disable default listview keyboard actions on flutter desktop to prevent it from listening to physical keyboard input / triggering built-in actions. Cheers.
I have a number of Dialogs that use a keyboard for text input. Whenever the keyboard is activated, the Dialog windows shift position upwards and resize.
I would like to stop this behaviour so that the keyboard is forced over the Dialog content. Is there a way to force this?
I have set resizeToAvoidBottomInset: false in my Scaffold.
Note that I am using a DefaultTabController as a parent widget of my Scaffold
How can I implement default android Messages like a custom widget in place of the keyboard shown in the GIF?
When you tap on + button, what happens is,
Keyboard Closed, to achieve this you can use FocusNode instance and assign in TextField, to unfocus or to close keyboard, you can achieve it by focusNode.unfocus().
The content you see on tap of + is outside keyboard, i.e. you have to create widget and change it's visibility accordingly, Visibility can be used.
In other case misc options is visible and user tap on keyboard icon then change visibility of extra options and obtain focus of FocusNode instance(enable keyboard), by focusNode.requestFocus().
How would I override events e.g. OnmouseOver, OnMouseOut in extended widgets?
I am trying to extend the Anchor widget and want to set a certain stylename from my CSS.
In this case you could add handlers in you constructor via addMouseOverHandler and addMouseOutHandler and the handlers add/remove your stylenames.
Another option is to override the OnBrowserEvent(Event event) method on catch the mouse over and mouse out events.
However, mouse out events won't work perfect in all browsers. Sometimes the mouse out event is not triggered on the widget and you're style will stay on the widget. If you want to set style on a widget you could also add a yourstylename:hover in you're style sheet, such that you let the browser do the work of adding and removing the stylenames.
