How can I handle OnExit, Key Pressed, Key Down, Key Press, Key Up event on TUniButton

[BantuKumar]

Hi,

 

I am wondering if it is possible to handle following events in TUniButton.

 

OnExit - Occurs when the input focus shifts away from one control to another.  

Key Pressed,

Key Down,

Key Press,

Key Up

 

Thanks & Regards,

Hi,

 

For now one of the possible variants, you can use the "ClientEvents" and "OnAjaxEvent":

for Example for OnExit:

 

UniButton1 -> ClientEvents -> ExtEvents ... blur fn:

function blur(sender, the, eOpts)
{
  ajaxRequest(sender, "_onExit", []);
}

and

procedure TMainForm.UniButton1AjaxEvent(Sender: TComponent; EventName: string;
  Params: TUniStrings);
begin
  if EventName = '_onExit' then
  begin
    ShowMessage('Exit');
  end;
end;

Other events similar to this...

 

Best regards.

When does OnAjaxEvent of a control trigger? I tried this with button and I could only figured out it for mouse click in on button.

Sorry, can you clarify ?!

Sorry, can you clarify ?!

 

Ohh...!

 

I mean to say. Do I need always need to fire the AjaxRequest manually (like you did in blur) or it automatically fires?

For button_click event TUniButton was triggering AjaxRequest automatically. So I was wondering if you can tell me about the actions that can triggers AjaxRequest event for a control.
