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.

I ask if konva.js may behave like other graphics libraries as Raphael.js or Paper.js when the mouse is pressed and then leaves the canvas or browser window, this video illustrates the difference in behavior by default.

Is there a trick to konva.js work the same way?
(google translator)
It is fixed in develop version.
You can get the last build here: https://raw.githubusercontent.com/konvajs/konva/master/konva.js
I am trying to create an animation to a control.
So think of the animation and control of a now playing page on most touch screen devices. You see the control (album photo) and swipe either way and get it to slide off the screen and then the next control (album photo) slides on in its place.
I am not asking for you to code me this, but I am having trouble wrapping my head around a way that this could be done.
The control content is always changing, when you swipe one way, an image is removed from the view and then the next is added.
What you need is FlipView control which can get you the interface you described.
Here are some references:

I'm trying to create a simple animation example on the Windows Phone 8, but I imagine this should apply for WPF, WinRT, etc. anywhere XAML is used.
How do you animate the opacity of an to change from 0 to 1 when a 's click event is fired?
I've seen many examples of animations, but the button is always animating it's own properties, not the properties of a different control. I know I'm missing something small but I'm stumped -- no matter what I try I get XAML parse exceptions. I can get this to work with C#, but not with XAML.

Both GridView and ListView have a nice "bounce-effect" when you try to scroll beyond the begin or end.
Some applications (on other platforms) use this "drag-beyond-end" gesture as a trigger for some actions, like loading more items.
How can I detect this "state" (=user is at the begin/end and tries to scroll beyond that) in Windows Store App using XAML/C# ?
The rubber-band effect cannot be detected by code in a Windows 8 app (verified with the XAML controls team).
One way you could do that would be by handling all the inputs and the rubber-band effect yourself, but that is a bit of work, it reduces scrolling performance and requires manual handling of input on any list elements as well, so I would only recommend it as a last resort.
Also note the problem of the mouse input scenario since mouse scrolling doesn't involve this pull-beyond-edge behavior.
If you just want to load more items when you reach the end of the GridView, implement the ISupportIncrementalLoading interface with your collection derived from ObservableCollection<T>. See the answer here Load more items on grid view scroll end.
I am looking to use the nativeWindow.startMove() to drag the chrome around, but with a touchEvent rather than a mouse event. I'm not sure if this is at all possible after extensive googling.
I have also tried to dispatch manual mouseEvents when a touchEvent is fired.
Ultimately is the startMove function strictly a mouse only driven function, or can I force this to occur through a touchEvent?
Any input would be most grateful :)
You can manually change x and y properties of the NativeWindow in response to TouchEvents, not necessary using startMove().
