Input Service for Jetpack Compose

I'm building my own soft keyboard for my app.
I was wondering if there was a way of popping open my custom keyboard instead of the default android soft Keyboard.
For example, when clicking on a TextField, I would like my custom keyboard to be the input source.

Reacting on Head Event at Kinect

I just wanted to ask how to handle the Event when for Example the Head comes in the Sensorview. I did read the Documentation, but dont find the Method for that.
There is no event emitter from the SDK for your purpose. You need to pool Bodyframe and check is there any new skeleton is arrived. You can check out my repository if you need any reference, In there I build more complicated gestures such as click and swipe gestures.

Create a keyboard shortcut for a button in a windows app?

Create a keyboard shortcut for a button in a windows app?
I have an Autodesk Revit app which i use for CAD.
There is a button in this app that does a "Fit to view" command. You click it and a 3D view centers around an object.
The app does not allow me to bind this "action" to a keyboard shortcut in it's current version.
If you use a Spacepilot 3D mouse this action si available to one of its the buttons.
Is there any way to bind this to a keyboard shortcut using some kind of software?
Revit also allows extensions through it's API so this might be a way also.
Apparently there is a "Zoom to awesome" addin that uses the API to do that but only in plan view not 3d camera perspective views like you can do with the viewcube.

How to implement simple javascript touch events for webkit on WebOS while developing web content

did anyone come across difficulties while trying to implement simple js touch events for webkit and found a solution for it ?
Basically my touch start, touch move, and touch end events are not being detected.
Thanks
Palm webOS's webkit doesn't implement touch events at this time. Instead, the system sends gesture events. These aren't super well documented, but they are used in the mojomatters sample code that's part of the Palm webOS SDK. Look at the gesture-assistant.js source file for gestureStart, gestureChange, and gestureEnd.

How to catch scrolling events in wxGTK?

I have a wxTextCtrl with a vertical scrollbar. I need to capture scroll events from the text control's scrollbar. I have a handler for EVT_SCROLL but it only gets invoked on the Windows build. On wxGTK it does nothing. Is there any way to make this work?
No, EVT_SCROLL, like many other events, only works for wxWidgets windows and not the native ones.
You can use wxRichTextCtrl or wxStyledTextCtrl but you probably won't find any way to be notified about scrolling in the native GTK+ text widget.
