uninumber edit value if empty

[jahlxx]

Hi.

 

I need some uninumberedit get the value as 0, when they have emty text.

 

I have trested with emptytext := '0', and minvalue := 0, but when the user "empty" the field, it doesn't take the value 0.

 

is some vcl components, I have the property valueifempty.

 

How can I solve this with unigui?

 

Thanks.

Hi,

 

Maybe, for now you need to use this approach ?!:

 

UniNumberEdit -> ClientEvents -> ExtEvents -> blur fn:

function blur(sender, e, eOpts)
{
    var me=sender;
    if (Ext.isEmpty(me.value)) {
        me.setValue(0);
    }
}

Best regards.

Can you try these events?:

procedure TMainForm.UniNumberEdit1ChangeValue(Sender: TObject);
begin
  if (Sender as TUniNumberEdit).Text = '' then
    (Sender as TUniNumberEdit).Value := 0;
end;

Or

procedure TMainForm.UniNumberEdit1Change(Sender: TObject);
begin
  if (Sender as TUniNumberEdit).Text = '' then
    (Sender as TUniNumberEdit).Value := 0;
end;

for every numberedit in every form?

 

huge work.

 

why don't work emptytext property?

 

or perhaps I don't understand the meaning of that property.

Also you can try this:

procedure TMainForm.UniFormCreate(Sender: TObject);
begin
  UniNumberEdit1.JSInterface.JSAddListener('blur', 'function(me){if (Ext.isEmpty(me.value)) {me.setValue(0)}}');
end;

I am sending you an example.
When you delete all the values in the above component, you will see the value of -1.

* If the onchange feature is -1, do not say 0, after all, the user can give a value of -1.
