Hi,
I would like to change bk color of a EditString (edit) when the change event takes place. Is there any other way to do this appart from rewriting the Paint event?

Thank you,
Alex

Something like:

EditField::Style editstyle; // Member variable of owner window

void OnEditChange()
{
    editstyle = EditField::StyleDefault();
    editstyle.paper = SLtBlue();
    
    editfield.SetStyle(editstyle);
}

Many thanks!

By the way, what is the name of the OnChange event (CALLBACK) of the EditString

Edit1.change <<= THISBACK(OnChange);

change does not exist.
Is there any doc, help or trick to know the name of all events a specific control supports?

1. type the name of the ctrl then '.When'. As almost all callbacks are of the form WhenSomething this gives a list of the callbacks.
2. Check the source. Press Ctrl-Q, type EditField, then click on one of the options at the bottom of the screen to go to the header file.

In this case the action you want is default ctrl callback WhenAction, so:

editfield <<= THISBACK(OnChange);

editfield.WhenAction = THISBACK(OnChange);

will work.

I'm very sure it does since I was the one who added it Smile

. Are you using an older version of Upp? It's there in 2008.1, not sure about 2007 version.
