iOS Question Hide keyboard event?

[rfresh]

Am I able to detect when I manually hide the keyboard? I'd like to clean up a text input panel if I choose to change my mind and manually hide the keyboard.

Thank you...

Hi,

the question is: In which case was the keyboard hide manually in your opinion?

When I'm using the keyboard and am finished with it, I press the lower right key which has the KB icon and the keyboard slides down and out of sight. I'm wondering if we have an event that I can hook into so my app can do a few small clean up tasks.

Hi,

use the _EnterPressed event, which is always fired when you press the return key.

I am using that now but that doesn't hide the keyboard. I can do my clean up needed but the BD is still there. In that event I could hide the keyboard and that would work but how do I hide the BD using code? That would be a work around but I'd still like to be able to detect the user pressing the BD hide key because I'd still need to do the clean up stuff.

Check B4XFloatTextField from XUI Views. It adds a Check button that hides the keyboard and raises the EnterPressed event.

You can call TextField.ResignFocus to hide the keyboard.

Yes, I am doing that now and that does hide the KB. I am asking if the user presses the key (lower right corner) shown in the attachment, if I can detect that? That key hides the KB and I need to do some code clean up if the user just chooses to hide the KB.

Handle the EndEdit event.

That doesn't do what I'm asking for: I am asking if the user presses the key (lower right corner) shown in the attachment, if I can detect that?

You are correct. It is not triggered.

The only event that you can handle in this case is the page KeyboardStateChanged event:

Private Sub Page1_KeyboardStateChanged (Height As Float)
   Log(Height)
End Sub

It will be 0 when the keyboard is completely hidden (there is another "short state" in iPad).

 

[rfresh]

Yes that event works...Height is 0 when I hide the KB.

When I run in the debugger I see this line in the logs window:

Unexpected event (missing RaisesSynchronousEvents): page1_keyboardstatechanged:

It seems like you can ignore that message. See here:
