Capturing key press in VFP custom section

[hmischel@diligentsystems.com]

Hi,

I have several items that I need to have the user move around on the screen.
To make this quick, I allow different keystrokes for the different items.

Is it possible to use something like "on key label ctrl+leftArrow mytext.left = mytext.left -2"

Thanks.

Hi Herb,

Thats an old foxpro command. Not supported.

What sort of UI controls is it that you want to move about the screen? What type of section are these in?

Hi Barry,

These are images that I need to move side-by-side (and sometimes overlay).

In the application that I am replacing, I use different keystrokes to change the focus between images and then the arrow keys to move them.

This would be in either a custom VFP section or a Canvas VFP section.

Thanks.

Hi Herb,

An image In a custom section the KEYPRESS event handler is called with 2 args:

proc mykeypress(keycode as numeric, keymodifiers as numeric)
// your code here
endproc

Hi Barry,

I am not seeing a keypress delegate in the custom section.
But perhaps I am not understanding exactly how to do this.

Thanks

Hi Herb,

So you're looking for something ike ON KEY LABEL etc. from VFP?

Yes - and I think it had it working a while back, but I am not as young as I used to be....

Hi Herb,

Use the Section Hotkey event delegate.

v3.2: Added a new "Hotkey" delegate to "App", "Page" and "Section". This is only called in runtime mode so you need to switch into that mode to test your delegates. The delegate is called with one argument which is the keycode string e.g. "F5", "Ctrl+F5", "Ctrl+Shift+F5". If the current section has a hotkey delegate that is called otherwise if the page has a hotkey delegate that is called otherwise if the app has a hotkey delegate that is called.

Hi Yvonne,

What are the rules around hotkeys?
ctrl+right works, so does left, up and down.

what about ctrl+z or ctrl+shift? those don't seem to work.

Thanks
