how to catch CodeEditor keys? [message #47894] Wed, 19 April 2017 18:22 Go to next message

default subclassing,eg:
virtual bool Key(dword key,int count){
  return CodeEditor::Key(key,count);
}

doesn't seem to work-it's not called, or am i missing something?
for now i am using some hokus-pokus...

By the way, is there an easy way to convert key characters<65536 into virtualKeyCode,
so that Shift/Ctrl/Alt can be used/known independently - eg, when 2 is pressed to check if Shift was pressed too?
like Ctrl-2 or Shift-2, some kind of translation table or something?

This looks fine. If it does not get called, problem is probably elsewhere. Testcase would help to identify it.

Not sure if that will answer your question, but you can definitely use e.g. K_SHIFT|K_2.

Maybe the confusing part is that Key recieves both 'translated characters' and 'key codes'. So if user presses '2', Key gets K_2 and and '2' (order is not specified).

I'm not into this right now, but:

1)>>
Default subclassing:
  this is probably more or less because i'm inserting 'layout' window into layout window,
  is there an easy way to use this, so default subclassing works as expected?

2)>>
It turned out it was easier to use like it is,without any translation tables - just directly(if keyCh<65536...),
  but that 'keys used independently' may come handy sometimes,
  aha, for confusing part and K_SHIFT|K_2

Maybe your key is processed by some widget?
